Paypal_lib Success Page Problem

[eluser]Jesse Schutt[/eluser]
This code is in the "Success" view of the Paypal_lib. It is not displaying any information regarding the _POST information. Actually, it isn't displaying anything at all other than the "Success, Your Payment was received..." Any ideas?

Code:

<h2>Success!</h2>

<p>Your payment was received using Paypal.</p>

&lt;?php if($this->input->post()): ?&gt;
<p>Here's its information:</p>
<p><code>
&lt;?php    
    foreach ($this->input->post() as $key => $value)
        echo '<strong>$key</strong>: $value <br/>';
?&gt;
</code></p>

&lt;?php endif; ?&gt;

If I insert the following, I can see results, so I am pretty sure that there is _POST data.

Code:

<?php
if (isset($_POST))
{
   print "<pre>". htmlspecialchars(print_r($_POST, TRUE)) ."</pre>";
}
else
{
   print '$_POST not set!';
}
?&gt;
