Hi

i'm realtively new At Whmcs and looking to extend its functionality

i'm not doing anything fancy here i m just trying to run the example hook you provided us with

but it gives me nothing can you guide me how can i run my code through hooks

 

This is what i changed in Example hook

 

if (!defined("WHMCS"))

die("This file cannot be accessed directly");

 

function create_forum_account($vars) {

print_r($vars);

$firstname = $vars['firstname'];

$lastname = $vars['lastname'];

$email = $vars['email'];

 

// Run code to create remote forum account here...

$content = $email;

$fp = fopen("myText.txt","wb");

fwrite($fp,$content);

fclose($fp);

}

 

add_hook("ClientAdd",1,"create_forum_account");
