Hi Frank,

usually the method is the following :

1. Create your kernel-override class in your extension, the class name obviously matching one of the kernel's
2. Run the following script from the eZ Publish root :

   php bin/php/ezpgenerateautoloads.php -o

3. Then run the "normal" autoload generation (same line as above, without he "-o" option).

No direct edition of the autolad files.

Have you tried this already ?
Let us know,

Nicolas

Hi Nicolas and thank you for your quick reply!

I do not have shell access, but the server owner ran the commands for me - this is the output:

Still not working :-(

Just a note: there are still a few places in eZP (esp. ez-approved extensions) where include_once and require_once are present, hardcoded to the php classes in the standard directories. You should take care about that when overriding the provided php classes...

Kernel override capability is great but there are 2 issues though :

1. Does not work with datatypes (sometimes really annoying)
2. When setting EZP_AUTOLOAD_ALLOW_KERNEL_OVERRIDE in config.php, it does a require_once() statement of var/autoload/ezp_override.php without testing if it exists. So you can have a PHP Fatal Error if you just plan to make a kernel override...

Hi Walter

Unfortunately overriding modules is not currently possible :(

Friday 30 April 2010 4:07:09 am

Hi,

A little trick to Override a module in ez, (this is not very clean but it can be useful when you can not do this otherwise)

In the file module.ini, define:

[ModuleSettings]
# Important to initialize the variable
ModuleRepositories []
ModuleRepositories [] =extension / [costum_extension] / modules
ModuleRepositories [] =kernel
ModuleRepositories []=kernel / private / modules

PS: But we must override all of the views's module.

I hope it will be useful for someone;)

Extension arh_jdebug : EzDebug using jquery

Friday 30 April 2010 10:41:24 am

@Jérôme, yes, every day we discovered new things about EZ :)

In fact we can do the same thing to override the datatype. On a project, I overloaded single relation object datatype in order to redirect the link browse to the destination defined in the class. and it work well.

to do it, edit file content.ini, and set the parameter :

[DataTypeSettings]
RepositoryDirectories []
RepositoryDirectories []=extension/[Costum Extension]/datatypes
RepositoryDirectories []=kernel/classes/datatypes

Regrads

Tks

To override the default shop user handler (kernel/classes/shopaccounthandlers/ezusershopaccounthandler.php) you need to create settings/override/shopaccount.ini.append.php:

 <?php /* #?ini charset="utf-8"?

[HandlerSettings]
Repositories[]
Repositories[]=extension/your_extension/classes
Repositories[]=kernel/classes

*/ ?>

Then take a copy of kernel/classes/shopaccounthandlers/ezusershopaccounthandler.php to extension/your_extension/classes/shopaccounthandlers/ezusershopaccounthandler.php

Then run kernel override autorun. Easiest way to verify that it is working is just to echo something in the beginning of your custom ezusershopaccounthandler.php
