The following requirements exists for using BC XML Template Override Conditions extension:

eZ Publish version

  • Make sure you use eZ Publish version 5.x (required) or higher.

  • Designed and tested with eZ Publish Community Project 2014.11

PHP version

  • Make sure you have PHP 5.x or higher.



  • This solution depends on eZ Publish Legacy and kernel class overrides enabled in config.php

Kernel class override

This solution overrides the following kernel class:

  • PHP Class : eZXMLOutputHandler - Found by default at: kernel/classes/datatypes/ezxmltext/ezxmloutputhandler.php

This solution provides the following kernel class override:

  • PHP Class : eZXMLOutputHandler - Found by at: extension/bcxmltemplateoverrideconditions/classes/kerneloverride/kernel/classes/datatypes/ezxmltext/ezxmloutputhandler.php

Note: This solution requires only one legacy kernel class override of a class that is very stable and not subject to much change (if at all) per release (which is important for maintainability). The class has not been modified or needed a bugfix since late 2012.

Template override rule match conditions added

This solution provides the following ezxmltags template override rule match conditions you can use in your override.ini settings:

  • Provided by default in eZ Publish:

    • attribute_identifier
  • Added by bcxmltemplateoverrideconditions:

    • object
    • class
    • class_identifier
    • remote_id
    • node
    • node_remote_id
    • depth
    • url_alias
    • parent_node
    • parent_node_remote_id
    • parent_object_remote_id
    • parent_class
    • parent_class_identifier

Note: Additional match conditions can be added by patching the kernel override class and documentation. We support with this solution nearly all possible match conditions (minus state and some other more obscure and rarely used conditions).


Extension Installation via Composer

Run the following command from your project root to install the extension:

bash$ composer require brookinsconsulting/bcxmltemplateoverrideconditions dev-master;

Extension Activation

Kernel class override extensions are not activated via ini settings. Normal site.ini extension activation settings are not required to use this extension and it's solution.

Enable eZ Publish Kernel Overrides

Kernel class overrides are only able to be used if you add the following to your eZ Publish Legacy config.php configuration file.

cp -va config.php-RECOMMENDED config.php;
# Edit config.php to set 'EZP_AUTOLOAD_ALLOW_KERNEL_OVERRIDE' to true. It should look like this:

Regenerate kernel class override autoloads

Regenerate kernel class override autoloads (Required).

php ./bin/php/ezpgenerateautoloads.php --kernel-override;

Clear the caches

Clear eZ Publish Platform / eZ platfrom caches (Required).

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


The solution is configured to work virtually by default once properly installed.

You can use the additional override.ini rules match conditions within your settings to use this solution's features
