Simple fromString and toString interface for attributes

This is a copy of only document available that describes the extremely useful toString and fromString functions of datatypes, which greatly simplify storing and retrieving attributes in php.

This is a design document, so there may be some inaccuracies but it seems to work ok into the 4.2 series. It is recommended to verify the format of not-trivial datatypes by doing toString on attribute of that type with data in it and examining output.

Source: https://pubsvn.ez.no/nextgen/trunk/doc/features/3.9/to_from_string_datatype_functionality.txt

To simplify writing of import export scripts we have added two functions to the ezcontentobjectattribute class. Also related functions with the same name have been added to the datype interfase and to all datatypes in standard eZ Publish distribution exept of ezenum which is now deprecated and ezpackage which is not used.

To show possibilities of these functionality two scripts have been added under bin/php/. These scripts are very simple CSV import/export scripts:
- ezcsvimport.php
- ezcsvexport.php
They are very basic and do not pretend to be fully functional CSV import/export for ezpublish though you can use them to do real import/export. Here is a description of formats which are accepted by the datatypes for
fromString( &$contentObjectAttribute, $string ), and generated by toString( $contentObjectAttribute ) methods.

ezauthor:
To separate one author from another '&' char is used, to separate parts of author data '|' is used. The system escapes '|','&','\' with the '\' char.
Example of toString result:

To make it easy to parse such kind of strings the class ezstringutils is added under lib/ezutils. It has to functions as a members.
explodeStr( $str, $delimiter = '|' ) and implodeStr( $str, $delimiter = '|' ). The first one explodes string to an array with delimiter char, the difference from PHP explode/implode is that these functions do propper escaping/unescaping of all values.

ezbinaryfile:
toString function of this datatype return string of format:
filepath|original_filename
filepath is to a file in filesystem so you can make copy of the file.
original_filename is the original filename of uploaded file as string.
To import binary file to the attribute you need to supply it with full path
to the source file, which will be copied into system.

ezboolean:
Returns and accepts 1 or 0 for true and false accordingly.

ezcountry:
Returns comma-separated list of selected countries locale strings, ex.:
rus-RU,eng-GB,nor-NO

ezdate:
Returns and accepts unix timestamp of the date.

ezdatetime:
Returns and accepts unix timestamp of the date.

ezemail:
Returns and accepts email address.

ezenum:
Not supported (deprecated)

ezfloat:
Returns and accepts float number.

ezimage:
Returns path to file containing original alias (size) of the image, so it can be copied. Accepts full path to original image you want to import, it will be copied into system.

ezinisetting:
Returns and accepts value of an inisetting.

ezinteger:
Returns and accepts integer value.

ezisbn:
Returns and accepts ISBN number as string

ezkeyword:
Returns and accepts comma separated list of keywords.

ezmatrix:
Identical to ezauthor datatype. The columns are sparated with '|' and rows are separated with '&'

ezmedia:
toString function of this datatype return string of format:
filepath|original_filename
filepath is to a file in filesystem so you can make copy of the file.
original_filename is the original filename of uploaded file as string.
To import binary file to the attribute you need to supply it with full path
to the source file, which will be copied into system.

ezmultioption:
The first '&' separated value is the name of multioption set, then each '&' separated string represents
each option in multioption set. This string it self is '|' separated value, that consist of, in this order:
_name_ of the option and the _id_ of option item which should be selected by default. After these two
values we have option_value and additional price for the option item.

ezmultiprice:
The structure of a data handled by this data type is
currency_name_1|value_1|type_of_price_1|currency_name_2|value_2|type_of_price_2|......currency_name_n|value_n|type_of_price_n|
Where currency_name is thre char currency name like EUR,USD and so on,
value is the price in this currency,
and type can be AUTO or CUSTOM dependin on if the price in this currency
has been inserted by user or calculated automaticaly.

ezobjectrelation:
Returns and accepts ID of related object.

ezobjectrelationlist:
'-' separated list of related object ID's.

ezoption:
'|' separated list of name of the option and then | sparated list of option_item|additional item price values.

ezprice:
'|' separated list of price, VAT id, and flag wether VAT is included to the price or not.

ezproductcategory:
Returns '|' separated string with product category name and category id. Accepts just category
name as a papameter.

ezrangeoption:
'|' separated string contains name of the option, start,stop and step values for the option.

ezselection:
'|' separated list of selected item names.

ezstring:
Returns and accepts the string value.

eztext:
Returns and accepts the string value of eztext field.

eztime:
String with the time of the day in HH:MM , 24h format

ezurl:
string containing the url

ezuser:
'|' separated string with user login, email, password hash, and password hash type.

ezxmltext:
Returns valid ez publish xml, and expects the same as input.

Extended sort

Tue, 01 Dec 2009 16:00:35 GMT

Requirements

For taking proper advantage of this feature you should know something about:

writing an extended_attribute_filter (fetch content list)
SQL
the eZ Publish database layout

Function

There is an undocumented feature in the eZ Publish fetch content list function for sorting on arbitrary sql statements. On regular fetches this feature is not available. However, when including an extended_attribute_filter parameter in the fetch, eZ Publish allows the user to sort on any arbitrary sql clause.

Use

Add an empty 'extended_attribute_filter' parameter in the fetch like this: 'extended_attribute_filter', hash(). Then add a 'sort_by' parameter, like this: 'sort_by', $sql_statement.

The sql string in the $sql_statement variable is inserted directly in the ORDER BY sql clause. Tables included by a regular fetch content list are:

ezcontentobject_tree
ezcontentobject
ezcontentobject_name
ezcontentclass

which means that any fields within these tables can be used in the $sql_statement string. If a sort_by attribute is involved, the ezcontentobject_attribute table are also included.

Furthermore, if required one can add other tables in an extended_attribute_filter's code, giving you access to sort on any field or combination of fields in the database.

Examples

fetch( 'content', 'list', hash( 'parent_node_id', 2,
                                'sort_by', array( 'ezcontentclass.identifier ', true() ),
                                'extended_attribute_filter', hash()
    ) )

This example will sort the resulting node list by the class identifier string. Note that this will not work if the extended_attribute_filter parameter is not included.

fetch( 'content', 'list', hash( 'parent_node_id', 2,
                                'sort_by', array( array( 'cast( a0.data_text as unsigned )', true() ),
                                                  array( 'attribute', true(), 'article/select_attribute' ) ),
                                'extended_attribute_filter', hash()
    ) )

This sorts an attribute of the selection datatype in the article class by the selection id as a number (and not by selection id as a string, as is default for this datatype, which makes the sort fail on id's above 9). The second sort element tricks the fetch into including the ezcontentobject_attribute table in the sql, named as a0, but will not have any effect on the actual sorting.

fetch( 'content', 'list', hash( 'parent_node_id', 2,
                                'sort_by', array( 'obj.name ', true() ),
                                'extended_attribute_filter', hash( 'id', 'ObjectRelationSortFilter',
                                                                   'params', hash( 'relation_attribute_id', 337,
                                                                                   'related_class_attribute_id', 343 ) )
    ) )

Here is an example on how to sort the nodes by an attribute of the related objects in an object relations attribute.

This example requires an extended_attribute_filter to include the right tables, the main function of the code for this follows...see the extended_attribute_filter documentation for setting up this.

function sqlObjectRelationSort($params)
    {
        $sqlTables= ", ezcontentobject_tree AS node
                LEFT JOIN ( ezcontentobject_link AS link, ezcontentobject AS obj, ezcontentobject_attribute AS attr )
                ON ( node.contentobject_id = link.from_contentobject_id AND
                    node.contentobject_version = link.from_contentobject_version AND
                    link.contentclassattribute_id = {$params['relation_attribute_id']} AND
                    link.to_contentobject_id = obj.id AND
                    obj.id = attr.contentobject_id AND
                    obj.current_version = attr.version AND
                    attr.contentclassattribute_id = {$params['related_class_attribute_id']} )";
 
        $sqlJoins = ' ezcontentobject_tree.node_id = node.node_id AND ';
 
        return array( 'tables' => $sqlTables, 'joins'  => $sqlJoins, 'columns' => '' );
    }

As you see, this filter requires two parameters. relation_attribute_id is used to specify the attribute id of the object relation. related_class_attribute_id is used to specify the attribute id of the related object that is to be sorted on. This function requires that all nodes are of the same class, and all related objects in the specified object relation attribute are of the same class.

This can potentially be further expanded to sort on the attributes of the children of the nodes. This is left as an excercise for the reader.

Debugging

Whenever developing extended_attribute_filters or extended sorting, switch on the SQL output in the debug in settings/override/site.ini.append.php:

[DatabaseSettings]
 
SQLOutput=enabled
 
[DebugSettings]
 
DebugOutput=enabled

If you can't immediately see what is wrong, copy the complete sql statement from debug and paste it into your favourite SQL program. It is a lot easier to make the sql work there than to test it against eZ Publish.

indexing/searching pdf files with accented chars

Thu, 24 Sep 2009 13:53:57 GMT

eZpublish needs external tools for pdf file indexing. Path to that tool is set in binaryfile.ini

Originally i was using the pstotext too, but it does not work well and often gives garbage as output. Better tool is pdftotext from xpdf project, as suggested in this article.

In my case the above was not enough, as pdf files apparently are in iso-8859-1 but eZpublish expects UTF-8 as input.

So, the contents of ezpdftotext should be:

#!/bin/sh
pdftotext $1 -|iconv -f ISO-8859-1 -t UTF-8

What to do if ez publish loads a blank page or error?

Mon, 31 Aug 2009 10:10:16 GMT

Clear the caches using a shell command (in sites root folder):

php bin/php/ezcache.php --clear-all --purge

Check var/log/error.log and php error log for more information.

Performance Tuning eZ Publish 4

About

Recommended eZ Publish 4 Apache configuration improvements for best possible production web server performance.

Topics

Application / Web Server

Apache

The basis of Apache PHP application server configuration requires virtual host configuration be stored within Apache solely.

The htacess Problem

The basis of Apache PHP application server configuration best practices for performance is preventing the use of htaccess configuration usage as not-possible as it prevents best practices and reasonable performance.

This is because .htaccess files are check per http request, ie: per file included on webserver from browser within html page (including html page) ie many many times per requested page to set any required httpd / php application configuration variables / conditions / etc (ie: loading the web server configuration) from direct disk access each time (not cached).

This represents a tremendous systemic performance problem that can only be resolved by relocating all configuration changes to the Apache virtual host configuration file and disabling .htaccess file access completely.

Remember htacess files configuration syntax is almost always different than the same applicable syntax within an apche virtual host configuration file.

Disable htaccess

Here is an example of how to disable htacess file access using the AllowOverride None setting. This example would be added within your virtual host configuration file for your we eZ Publish installation within Apache.

<Directory /var/www/path/to/ezpublish>
  Options Indexes FollowSymLinks MultiViews
  AllowOverride None
  Order allow,deny
  allow from all
</Directory>

Recommended Apache Modules

mod_expire - Greatly improves performance
mod_rewrite - Greatly improves application server flexibility and provides for clean user friendly aka nice urls.

PHP

I recommend increasing the following default php.ini variables to increase default limits to prevent future performance and upload limits from being reached as the default configuration is insufficient.

memory_limit
max_input_time
upload_max_filesize
post_max_size

Database Server

What follows is based on certified results and has been tested and proven in practice. Please discuss any corrections and additionally needed information before making changes.

About

About software coding standards

General

Enforcing a software coding convention is a recommended best prance

What convention should I use?

The answer is simple. It's your choice. Your free to choose.

Yet it is strongly recommended that you follow the recommended convention.

If you are creating an ezpublish extension / site use the ezpublish conventions as they are directly applicable.

However if you are creating an ezcomponent itself you will want to use the ezcomponents conventions as they are directly applicable.

eZ Publish

eZ publish has it's own coding standard convention. This convention has evolved over time but the documentation regarding these improved methodologies.

eZ Components

eZ Components also has it's own coding standard convention

How to enable large file upload support

Mon, 17 Aug 2009 15:31:07 GMT

This is a Stub article. Help the eZ Publish community by expanding it!

About

Web applications basically must usually be configured to support large file uploads as well as web servers.

I can't begin to remember to forget the first time I configured eZ Publish v1.x and Apache 1.x to support large file uploads.

Example

Here is an example solution

Steps

It sounds like you want to optimize your web server and php configurations together to avoid this error.

Evaluation: Which version of apache are you running?
1. Apache 1.3.x
- This sounds strikingly similar to an apache 1.3 (large file upload) configuration issue I've learned to avoid over the years. set LimitRequestBody to an int (file size in bytes) value larger than your largest file.
- I found I often needed this apache settings change along with the php settings changes to enable large file uploads with apache 1.3
- Based on the size of the file being uploaded. Consider raising the values of the post_max_size to a larger value than the file being uploaded, as well as the value of max_input_time and max_execution_time beyond the amount of time required to complete the upload of the file.
eZ 4.x, Edit ... to enable large file support withing web application.
1. Example missing. Must not be required (per say)

PHP 5.x, Edit relevant php.ini configuration values

max_execution_time = 45     ; Maximum execution time of each script, in seconds
max_input_time = 60 ; Maximum amount of time each script may spend parsing request data
;max_input_nesting_level = 64 ; Maximum input variable nesting level
memory_limit = 258M      ; Maximum amount of memory a script may consume (128MB)
 
; Maximum size of POST data that PHP will accept.
post_max_size = 201M
 
; Whether to allow HTTP file uploads.
file_uploads = On
 
; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
;upload_tmp_dir =
 
; Maximum allowed size for uploaded files.
upload_max_filesize = 201M

Overriding kernel classes within an extension

Thu, 13 Aug 2009 10:51:01 GMT

This feature is available since eZ publish 4.1.

About

The best way to override kernel classes within eZ Publish.

This article features solutions for both eZ Pubish 3 and eZ Publish 4.

Please notice that the primary solution described for eZ Publish 4 is a supported but not recommended feature.

Please use with care and caution when working with the internals of the eZ Publish Kernel.

Question

What is the best way to override default eZ Publish kernel classes?

Answers

Several solutions come to mind. The best solution in eZ Publish 4 is to override the class within an extension. Remember this should be considered kernel hacking which while allowed and even more supported than ever in eZ Publish 4 it is still causioned.

PATCHING

In the past the best way to do this was to simply patch the original file and replace it with a modified file within original kernel location.

Creating a Kernel Override Extension

This is the standard solution within eZ Publish.

Create and activate extension

See articles on creating an extension

Copy default kernel file into the extension.

Remember pathing is a relative scheme (pattern) which must be maintained within the extension directory root.

mkdir -p extension/customname/kernel/classes/; cp -va kernel/classes/ezcontentobjecttree.php extension/customname/kernel/classes/;

Configure config.php enable kernel overrides

Create if file does not exist in root of ezpublish directory. Edit config.php file and enable the following setting.

EZP_AUTOLOAD_ALLOW_KERNEL_OVERRIDE

Activating kernel override extension

Activate extension in settings
Regenerate autoload cache

./bin/php/ezpgenerateautoload.php -o

Upgrading eZ Publish 3.3 to 3.9

Sun, 09 Aug 2009 10:23:08 GMT

Prerequisits

If you need to upgrade eZ, start here:
https://ez.no/doc/ez_publish/upgrading

Examine this image carefully:
https://ez.no/doc/layout/set/full/ez_publish/upgrading/images/ez_publish_releases

Requirements

Backup the database!

Steps

Then, open Notepad and list your upgrade path, with every stop. You can then copy and paste out of Notepad onto the command line.
Pay particular attention to the scripts listed on each page (for example: upgrading from 3.3-5 to 3.4).
Some of the scripts don't run (due to version conflicts), and some are optional. Read the pages in the upgrade documentation carefully - or you'll have to do it over and over.
Take your time and be patient. The commands below are an example, you'll need to substitute your database access parameters as well as the siteaccess names.

Commands will vary between different upgrade paths.

mysql -udb_ez -p db_ez < update/database/mysql/3.4/dbupdate-3.3-5-to-3.4.0.sql
 
php-cli update/common/scripts/updateremoteid.php

Results

I upgraded from 3.3-5 to 3.8.6 and it went fairly smoothly.

Problems

Issues I did encounter

updatetoplevel.php updated override/content.ini.append.php like so, and the system didn't run well. (I commented the changes out):

#[NodeSettings]
#RootNode=4159
#UserRootNode=4160
#MediaRootNode=4161
#SetupRootNode=4163
#DesignRootNode=4162

Results

updateiscontainer.php didn't run, and although I normally don't make changes in the database - I changed the ezcontentclass table and set the is_container flag manually.

At this time, you should be able to use the admin console.
Go to Setup > Upgrade > and check the database consistency.
Manually run any SQL through the database engine.
Clearing the cache and updating the search index are important.

About

I am using the xrowecommerce extension from xrow and the paymentgateway directebanking which is written by all2e in order of us (wirverbindenwelten).

For a special shopmodification I need to have a paymentlimitaion by productclass.

This example is using a modified xrowecommerce extension.

in the paymentgateway event php I add the following to the execute function

$productPayment = $order->attribute( 'product_items' );

Also add the variable $productPayment to template through $process->Template['templateVars']

$process->Template['templateVars'] = array( 
  'event' => $event, 'product_gateway_limitation' => $productPayment 
 );

After this I check my product class in the template file selectgateway.tpl

by looping the product items in my $productPayment array as needed.

If u need help u are welcome in irc://irc.freenode.net#ezpublish and irc://irc.freenode.net#ezpublish.de

How to shrink or reduce the site of eZ Publish database backup dump files

Sun, 19 Jul 2009 18:38:48 GMT

Question

I have a small site like a blog with only a few hundred entries. My mysql database backup dump files have grown in size upwards to over 1,000 MB! How can I reduce the size or amount of data stored in the eZ Publish Database?

Answers

Sadly the size is quite common. We have seen much larger sizes in the GB of exports of active clean eZ Publish installation databases. Suggest reading up on the flatten.php an cleanup.php php cli shell scripts as these should help you reduce some database size.

Suggested steps

- Empty the trash for all users

- Run flatten.php and cleanup.php scripts

- Remove session information from database

eZ Publish will store session information in the database and you may need to enable the php configuration setting, 'session.gc_probability' to purge the expired sessions.

PHP Sessions

Confirm these values in php.ini

session.gc_probability = 1
session.gc_divisor = 100

eZ Publish Sessions

If you dump your database and review the file size and then review the contents you would find that the ezsession table often contains large amounts of session rows.

Mysql

You can quickly truncate the ezsession table using sql thus freeing the table of records.

mysql > truncate table ezsession;

PHP

Or you may use the eZ Publish PHP CLI API (cleanup script) to free sessions in eZ Publish.

php update/common/scripts/cleanup.php session;
php update/common/scripts/cleanup.php expired_session;

eZ ODF

Fri, 17 Jul 2009 09:55:35 GMT

This is a Stub article. Help the eZ Publish community by expanding it!

This feature is available since eZ publish 3.9.

The Open Document Format extension or in short ezodf allows you to import and export eZ publish content objects to the OASIS Open Document Format. From eZ publish 3.9 on, ezodf is included in the standard eZ publish distribution.

Before it's inclusion in eZ publish 3.9, the ezodf extension was called oo. The extension first allowed import and export of OpenOffice.org Writer documents (OpenOffice.org extension contribution page at ez.no), but later on it moved to the OpenDocument format (OASIS OpenDocument extension contribution page at ez.no).

About

For some of the nice feature of the ODF extension, like MS Word import and export and PDF generation via OpenOffice.org you need OpenOffice.org installed on your server and running as daemon.

You can follow the installation guide from the official ezodf documentation.

Solution: Converting MS Word or PDF on Mac

These instructions were written from the perspective of attempting to manipulating ms word or pdf documents on Mac OS X 10.4.11 Intel

First install open office, you may prefer to install this MacOS port of open office called, neooffice / neojava.

Step 1, Install NeoJava

Step 2, Follow eZ ODF Installation documentation steps almost to completion (wait till next step before starting daemon).

Install extension, macro, daemon, etc

Optional, Step 3, Before starting the daemon via command shell ...

Edit the file, extension/ezodf/daemon.php with a PHP editor and change line 40:

$ooexecutable = "openoffice.org-2.0";
 
to
 
$ooexecutable = "/Applications/NeoOffice.app/Contents/MacOS/soffice";

Summary

That's all and now you can work with it.

Works sometimes

Export PDF with errors in charset … ô
Export .doc with errors in charset
Import .doc, no socket

Templates

Also perhaps you want to offer some money for the open funding of new PDF templates for cooler PDFs out of eZ Publish:

https://ez.no/developer/open_funding/open_funding_projects/pdf_templating_export

Tested

This article was tested with the following

October 2007: XAMPP for MacOS X 0.7.0, 7

eZ Publish Version: 4.0.0rc1
PHP Version: 5.2.4

October 2007: XAMPP for MacOS X 0.7.0, 7

Functionality tested, Import / Export .doc and Export PDF
Webserver software, ApacheFriends' Xampp
eZ Publish Version: 3.10.0
PHP Version: 4.4.7

Issues

Perhaps of bug in Online Editor < 5.0

Installation Dependencies

Error: "sh: openoffice.org-2.0: command not found".

Commonly based this error in your reported error text informs you that you should add the program binary to your shell path and try executing the program again.

Error: "Set DISPLAY environment variable, use -display option or check permissions of your X-Server".

Often the problem is that the software requires open office to start and execute one of it's own conversion macros. This in turn requires the graphical X Window environment already installed, configured and running properly. It may not display a gui application window and refuse to start without one.

Possible Solutions

Install and run a standard X Window service on the server. Negatives: Consumes much more memory and and system resources. Positives: The simplest solution to setup and troubleshoot since you have a chance to see what is actually happening through the X Window gui screen.
Install and run a standard X Window service on a remote computer and set the shell environment variable, 'DISPLAY' on the eZ Publish server to direct the server's visual output to the remote machine. Advantages: This will naturally save on ram and system resources exausted while also introducing another dependency on one more server computer. Often depending on the networks involved this practice is discouraged in most non-LAN networks for performance reasons.
Install and run xvfb on the eZ Publish server (or the variant, xvnc). This saves on memory and introduces no external dependencies.

Rewrite

Tue, 23 Jun 2009 10:29:13 GMT

About

mod_rewrite uses a rule-based rewriting engine (based on a regular-expression parser) to rewrite requested URLs on the fly.

It supports an unlimited number of rules and an unlimited number of attached rule conditions for each rule, to provide a really flexible and powerful URL manipulation mechanism.

Quotes

``The great thing about mod_rewrite is it gives you all the configurability and flexibility of Sendmail. The downside to mod_rewrite is that it gives you all the configurability and flexibility of Sendmail.'' -- Brian Behlendorf | Apache Group
`` Despite the tons of examples and docs, mod_rewrite is voodoo. Damned cool voodoo, but still voodoo. '' -- Brian Moore

Performance

mod_rewrite enabled apache services perform faster than .htaccess for production services; performance best practices solution.

Enable mod_rewrite

Virtual host setup

Alternatives

.htaccess apache configuration rules

These .htaccess files are faster to use for development without additional configuration.

These are useful for some users who avoid apache configuration or virtual host configurations.

Converting HTML Form Post Variables into URL View Parameters

Sat, 20 Jun 2009 19:01:46 GMT

This feature is available since eZ publish 3.5.

About

A recommended feature within eZ Publish template language is the use of view parameters instead of ezhttp operators to access _GET or _POST variables. View parameters are eZ Publish cache friendly while ezhttp usage is not.

Example Problem

Often a problem arises during requirements analysis and development with eZ Publish is how to submit complex combinations of view parameters as _POST variables and transform those variables into view parameters and redirecting the browser.

An example of this might be a filter bar which limits the results of a fetch with a series of html form inputs and options.

This document should provide an example of turning the html form _POST variables into view parameters.

Solutions

At the end of the day this requires either using one of the following

javascript onSubmit/onClick solution (incompatible with text browsers to append parameters and redirect browser)
custom module view (compatible with all browsers and simple to create)
default '/content/action' module view in eZ Publish to provide this parameter type translation/redirection.

Default /content/action module view

This module view is provided in the default kernel but has some limitations

Variables

DestinationURL - This is the path to your view without starting slash. Don't use ezurl on this value as it would add a starting slash.
Parameter - Any input variable with the name ie, 'Example #1 In a custom template for the node uri, 'ez_publish_root_node/events'
Submit - This parameter is ignored and not translated. Apparently this includes multiple values with the same name.
All other parameters submitted within the html form elements be added with the /([name])/[value] view parameters format.

Example Form

<form action={"content/action"|ezurl} method="post">
 
<input type="hidden" name="DestinationURL" value="{$node.url_alias}" />
 
<input type="text" name="(keyword)" value="" size="12" /> <br />
 
<input type="checkbox" name="(year)" value="1999" /> <br />
 
<input type="checkbox" name="(month)" value="12" /> <br />
 
<input type="submit" name="Submit" value="Go" />
 
</form>

Result

Upon submit the user will be redirected to: 'ez_publish_root_node/events/(keyword)//(year)/1999/(month)/12' if both checkboxes are checked and no text is input.

Limitations and Problems

The primary problem with the default 'content/action' module solution is certain html form input _POST values are converted inconsistently due to the generic nature of the solution provided by default.

Checkboxes are only submitted if checked, textline could be optional and on submit send empty values and cause further user page loading / redirection problems.

These problems at any level require custom php to properly detect, evaluate and set reliable url + view parameters hence the recommendation to use the bcposttoview custom module solution if these limitations affect you and your code.

Custom module view

You could create a custom module view within an extension activated for your user siteaccess to provide custom redirection implementation (review the file kernel/content/action.php for the default example).

At some point I hope for someone to publish at least an example of such a solution for further modification as needed by the user / developer as a starting point for avoiding null values in url parameters in redirected url (a common short coming of using the default /content/action module method).

Example Solution

2009.09.20 Brookins Consulting published the bcposttoview module view extension which was an example (several in fact) self contained modules and module views within the bcposttoview extension. The name mirrored off of an old deprecated module view name ezposttoview mentioned online in conjunction as an older example of this functionality but not available to the public, while our bcposttoview is freely available example in response to the for mentioned need (above).

Javascript redirection

You could use javascript to convert html form variables into view parameters. This would be better when used in conjunction with ajax content request than simply html form variables to url variable conversion to avoid the need for a custom module view for redirection.

In the end we think a module view redirection provides better browser compatibility than javascript hands down. Although a javascript solution (or ajax solution) was used on top of the module view solution that would be just fine since it provides a reliable fallback for browsers without javascript.

Example Javascript Method #1

function defaultStaticFormToViewParameterUrlRedirect( suffixString = '' )
{
    var form=document.getElementById( 'form_search' + suffixString );
    var action=form.action;
 
    var todaySelect=document.getElementById( '(today)' + suffixString );
    var locationSelect=document.getElementById( '(location)' + suffixString );
    var keywordSelect=document.getElementById( '(keyword)' + suffixString );
    var eventTypeSelect=document.getElementById( '(eventType)' + suffixString );
 
    if (todaySelect.value)
    {
        action += '/(today)/' + escape( todaySelect.value ); 
    }
    if (locationSelect.value)
    {
        action += '/(location)/' + escape( locationSelect.value ); 
    }
    if (keywordSelect.value)
    {
        action += '/(keyword)/' + escape( keywordSelect.value ); 
    }
    if (eventTypeSelect.value)
    {
        action += '/(eventType)/' + escape( eventTypeSelect.value ); 
    }
 
    form.action=action;
}

Example Javascript Form (with fallback)

<form action={"content/action"|ezurl} method="post"  onsubmit="defaultStaticFormToViewParameterUrlRedirect( '' )">
 
<input type="hidden" name="DestinationURL" value="{$node.url_alias}" />
 
<input type="text" name="(keyword)" value="" size="12" /> <br />
 
<input type="checkbox" name="(year)" value="1999" /> <br />
 
<input type="checkbox" name="(month)" value="12" /> <br />
 
<input type="submit" name="Submit" value="Go" />
 
</form>

Example Javascript Method #2

function eventFilter( i )
{
   var filter=document.getElementById( 'EventFilter' );
   var filter_action=filter.action;
 
   var offset=document.getElementById( 'Offset' );
   var date=document.getElementById( 'Date' );
   var city=document.getElementById( 'City' );
   var state=document.getElementById( 'State' );
   var country=document.getElementById( 'Country' );
   var production=document.getElementById( 'Production' );
   var coordinator=document.getElementById( 'Coordinator' );
 
   if ( offset.value != '0' )
   {
   filter_action += '/(offset)/' + escape( offset.value ); 
   }
   if ( date.value != 'all' )
   {
   filter_action += '/(date)/' + escape( date.value ); 
   }
   if ( city.value != 'all' )
   {
   filter_action += '/(city)/' + escape( city.value ); 
   }
   if ( state.value != 'all' )
   {
   filter_action += '/(state)/' + escape( state.value ); 
   }
   if ( country.value != 'all' )
   {
   filter_action += '/(country)/' + escape( country.value ); 
   }
   if ( production.value != 'all' )
   {
   filter_action += '/(production)/' + escape( production.value ); 
   }
   if ( coordinator.value != 'all' )
   {
   filter_action += '/(coordinator)/' + escape( coordinator.value ); 
   }
   filter.action=filter_action;
}

eZ Publish 4.1 extension incompatibilities

Mon, 30 Mar 2009 18:09:28 GMT

eZ Publish 4.1 introduced a new way of loading certain plugins from extensions, which is not compatible with eZ Publish 4.0. Therefore your extension might not work on eZ Publish 4.1 and requires some changes.

Broken plugin types

The following plugin types use the new way of loading:

Binary file handlers
Cluster file handlers
Database cluster file handler backends
Database plugins
eZXML input handlers
eZXML output handlers
Image convertors
Package handlers / creation handlers / installation handlers

Switching to rewrite rules

Wed, 11 Feb 2009 15:42:24 GMT

Redirect old url conventions/patterns

If you're switching from a setup where index.php is occuring in the URL, to a rewrite rule based setup, you can make sure any old links are properly redirected (with HTTP status MOVED PERMANENTLY) to the new URL without index.php. Put this in the appropriate virtual host context of your Apache configuration:

RewriteRule ^/index\.php/(.*)$ /$1 [L,R=301]

Tips Running - Cronjobs and scripts with required arguments in limited hosting environment

Fri, 09 Jan 2009 14:15:30 GMT

Previous Title

Running cronjobs and scripts with required arguments / parameters in limited hosting environment

Question

How can I run eZ Publish scripts and cronjobs with parameters on shared hosting without ssh.

You may only be allowed to run php files as a cronjob without any parameters and without the possibility to browse eZ Publish directory.

You also may not have command line access. Yeah, this can be pretty frustrating, but can not find or afford a better hosting solution.

Solution

When your provider doesn't allow you to run cronjob tasks with parameters and when your server runs php-cgi.

In order to run cronjob task with parameters, you can create a separate php file and then create a cronjob task pointing to that file.

Custom Script Example

Here is an example of the solution using the data_import extension as an example.

File: /path/to/ezpublish/extensions/custom/cronjobs/run_custom_cronjob_script.php

<?php
 
$output = shell_exec('cd /path/to/ezpublish/; /path/to/php5 runcronjobs.php import_images_csv');
 
echo "<pre>$output</pre>";
 
?>

The above example creates an output (as seen in the code) so you will know if your import is successful or not.

Web Browser Example

You may for very small tasks be able to run the above file from a web browser as long as the script completes quickly as browser requests do not work well with long running tasks.

The following tasks have been reported to be able to be run from the web browser with success if only limited. Most successes have been reported to resolve around limited execution time.

Scripts: Custom Scripts - Try limiting the execution time
Cronjobs: Data Import - Try limiting how much complicated data import you attempt each time
Database: Dump / Load / Custom SQL- Try using phpmyadmin or other dba tools

Topics

Cache: You must use the new cache clearing script, 'bin/php/ezcache.php' to clear cache in eZ Publish (separate from autoload cache entirely)
Cache: You must now (almost constantly) regenerate autoload cache when adding or changing the php class contents of extensions with the ez php cli shell script 'bin/php/ezpgenerateautoloads.php' and not the admin module view controls (as these only reload the admin siteaccess enabled extensions within the autoloads which breaks all your user siteaccess extension dependencies, it's a nasty negative feature)
Workflow: The workflow system internals changed key variable names which means custom workflow events must be changed to mstch the new required style in eZ Publish 4.0 (Consider reviewing existing default kernel workflow events for examples of these changes)
