Hooks mechanism for TYPO3

Usage:

processHook

To call a hook, simple add the following code in any class of your code.

\Bitpatroon\Typo3Hooks\Helpers\HooksHelper::processHook(<class>, <hookname>, [<params>]);

• Class (I) can be the instance, the static reference or the classname i.e.
  • $this
  • self
  • \VENDOR\CALLING_HOOK_CLASS::class
• Hookname (II) is the name of the hook is the hook,
• Params (III) is a y reference passed array with values for the hook.

Register the hook

In your or any localconf.php, add the hook.

 $GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'][\VENDOR\CALLING_HOOK_CLASS::class] = [
        'className' => \VENDOR\CALLED_CLASS::class
 ];

• CALLING_HOOK_CLASS is the name of the class, as specified in (I).
• CALLED_CLASS is the name of the class, handling the hook

The class with the hook

Add a TYPO3 class CALLED_CLASS with the following code.

namespace VENDOR;

class CALLED_CLASS
    
    /**
     * Hook
     * @param array $params The parameter Array
     * @param object $ref   The parent object
     */
    public function MyHook(&$params, $ref)
    {
    
    }
}

Notice the $params is by reference. Changing the content affects the original array. $ref is the calling class. See (I).
