[Vtigercrm-developers] Vtiger Class Loader?

[Hamono, Chris (DPC)]

This is the hackiest hack I have ever done... and I have done a few



The problem: Replace a core class with my own custom class at runtime



The Solution (not overly tested) ...



Change /index.php and add the following after the last include statement



// do this as late as possible

require_once ('modules/yourmod/__autoload.php');







Create modules/yourmod/__autoload.php :-



<?php

define('MODULESPATH', realpath(dirname(__FILE__) . '/../') . '/');





// create our own autoloader

function my_autoloader($class) {

    if ($class === "Users_Record_Model"){

        return require_once MODULESPATH . "mymod/modules/Users/models/Record.php";

    }

    return false;

}



spl_autoload_register('my_autoloader',true,true);

?>



Create  mymod/modules/Users/models/Record.php :-



<?php

// replace the users record model with our own

$path = MODULESPATH . 'Users/models/Record.php';

$stuff = file_get_contents($path);

$newstuff = str_replace('Users_Record_Model','orig_Users_Record_Model' , $stuff);

eval(' ?>' . $newstuff);



class Users_Record_Model extends orig_Users_Record_Model {



...

classy stuff

...



}

?>



Voila





I would strongly recommend against using this hack. It was just an experiment...

That's really quite interesting... Worth a test certainly.



Thanks.
