Help with php!

[Duckface]

Hiya,

I've allowed the use of includingphp into the templates by adding this as a plugin hook in the global_start:

ob_start();
   include('/forums/donate/donate.php');
   $includedphp = ob_get_contents();
ob_end_clean();
vB_Template::preRegister('Donate',array('php_include' => $php_include));

And I've added this to the custom page 'Donate' (template):

{includephp}

Within the template, I have this when you click the 'Upgrade Now' button:

<form name="upgrade" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">

However, when the button is clicked, the php isn't recognized and it opens literally a link with the output:





Link:
http://spawnscape614.co.uk/forums/donate/donate.php

How can I get the php to be recognized?
