Here is a simple fix, try it if you are interested. Just copy/paste whatever is inside the code block to your donate.php file, make sure to overwrite the old contents:

PHP Code:

<?php

class DonateController extends AppController{

    private $view;
    private $subController;

    public function __construct(){
        parent::__construct("member");
    }
    
    public function index(){
        $mysidia = Registry::get("mysidia");
        $document = $mysidia->frame->getDocument();
        $document->setTitle($mysidia->lang->title);
        
        if($mysidia->input->post("recipient") and is_numeric($mysidia->input->post("amount"))){
            $recipient = preg_replace("/[^a-zA-Z0-9\\040]/", "", $mysidia->input->post("recipient"));
            $amount = preg_replace("/[^0-9]/", "", $mysidia->input->post("amount"));
            $recipient = new Member($recipient);
            
             if($amount < 0){
                $document->setTitle($mysidia->lang->fail);
                $document->addLangvar($mysidia->lang->negative);
            }
            elseif($mysidia->user->money < $amount){
                $document->setTitle($mysidia->lang->fail);
                $document->addLangvar($mysidia->lang->funds);
            }
            elseif($recipient->username == $mysidia->user->username){
                $document->setTitle($mysidia->lang->fail);
                $document->addLangvar("Cannot donate to yourself!");
           } 
            else{
                $mysidia->user->donate($recipient, $amount);
                $document->setTitle($mysidia->lang->success);
                $document->add(new Comment("You've just donated {$amount} of {$mysidia->settings->cost} to <a href='profile/{$recipient->username}'>{$recipient->username}</a>. "));
                $document->add(new Comment("You'll be redirected back to the donation page within 3 seconds. Click "));
                $document->add(new Link("donate", "here "));
                $document->add(new Comment("if your browser does not automatically redirect you."));
                header("Refresh:3; URL='donate'");
            }
            return;
        }

        $document->add(new Comment("This page will allows you to donate your money to other users. "));
        $document->add(new Comment("You currently have {$mysidia->user->getcash()} {$mysidia->settings->cost} left."));
        $document->add(new Paragraph(new Comment("")));

        $donateForm = new FormBuilder("donateform", "donate", "post");
        $donateForm->buildComment("Donate to: ", FALSE)
                   ->buildTextField("recipient")
                   ->buildComment("Amount to donate: ", FALSE)
                   ->buildTextField("amount")
                   ->buildButton("Donate", "submit", "submit");
        $document->add($donateForm);    
    }
}
?>
