HOW TO register the autoload of an embeded Zend like component in an Extension ?

Tuesday 10 November 2009 12:12:38 pm

Hi there,

I'm building an extension that will expose a bunch of template operators and modules that user a small component lib i wrote. This component, called Ewm is built using the Zend Coding standard.

I want to embed this lib in an extension and use the lib autoloader to avoid require/includes in operators and module functions

Can't find a way to include the Autoloader code somewhere. Who an i acheave this?

extension
  - ewmadapter
    - autoloads
    - design
    - lib
       - Ewm
    - modules
    - settings
    - translations

the autoloader looks like this (in Ewm/Autoloader.php) :

class Ewm_Autoloader
{
  static public function register()
  {
    ini_set('unserialize_callback_func', 'spl_autoload_call');
    spl_autoload_register(array(new self, 'autoload'));
  }

  static public function autoload($class)
  {
    if (0 !== strpos($class, 'Ewm'))
    {
      return false;
    }

    require dirname(__FILE__).'/../'.str_replace('_', '/', $class).'.php';

    return true;
  }
}

Or you can set it up in config.php, have a look in config.php-RECOMMENDED file, it includes an example in the bottom.

This means the users of your extensions would need to set this up as part of the extension installation procedure, but should be simple if you provide examples in your installation doc.

It should work in 4.0 too. In fact, ezpgenerateautoload.php looks for class definitions in all PHP files of each extension.

Btw, I've just discovered that from the 4.1, you can also define and register your own autoload function and register it in config.php but as said by André, it's less handy, if you want to distribute your extension.

This means:

// Append your directory to the include path
set_include_path( get_include_path() . PATH_SEPARATOR . 'extensions/xyz/library/');

// Just create the new object it, or do a spl_autoload_call( $className );
// to look for the class before you try to initiate it.
$object = new $className();
