Add rules to autoload

Hi there,

I would like to know if it is possible to add rules to autoload through ez extensions without having to alter /autoload.php .

My problem is that I have to include an extra library to read some xls files.

It works well outside of ezpublish. But to integrate it I have to add some things in the beginning :

$path = './Classes/';
    set_include_path(get_include_path() . PATH_SEPARATOR . $path);

    function __autoload($classe)
    {
        $fichier = str_replace
           (
             '_',           # Caractère à remplacer.
             DIRECTORY_SEPARATOR, # Caractère de remplacement.
             $classe              # Cible du remplacement.
           ) . '.php' ;
        require_once($fichier) ; # Chargement de la classe.
    }

    // Because the name of the classes is made of the full path to the class file
    // ex. : $objet = new PHPExcel_Reader_Excel5();

Hi Damien

Yes, this is possible, but not inside extensions. You will need to alter your config.php.

Here's an extract from config.php-RECOMMENDED :

/*
   CUSTOM AUTOLOAD MECHANISM
   -------------------------
   It is also possible to push a custom autoload method to the autoload
   function stack. Remember to check for class prefixes in such a method, if it
   will not serve classes from eZ Publish and eZ Components.
   Here is an example code snippet to be placed right in this file, in the case
   you would be using your custom Foo framework, in which all PHP classes would be
   prefixed by 'Foo' :

   <code>
       ini_set( 'include_path', ini_get( 'include_path' ). ':/usr/lib/FooFramework/' );
       require 'Foo/ClassLoader.php';

       function fooAutoload( $className )
       {
          if ( 'Foo' == substr( $className, 0, 3 ) )
          {
              FooClassLoader::loadClass( $className );
          }
       }
       spl_autoload_register( 'fooAutoload' );
   </code>

Hi Damien, in fact you can use external libraries without altering config.php, see here:

It looks interesting too. I'll look at this when I'll have some time

Thanks
