Snippet not working in MODx

I've got a snippet in my ModX Evo. The problem is that on my local this shippet is working ok,but when I upload it to the host it returns only blank space. The code is a mess, but I need to get figured that out. Any ideas?Thx.

    <?php
$action=$_GET['action'];

switch ($action){
case('add'):_add();break;
case('view'):_view();break;
case('order'):_order();break;
case('del'):_del();break;

}
/////////////////////////////////////////////////////////////////
function _add()
{
global $modx;
session_start();
if(!session_is_registered('things')){session_register('things');}
$ar=$_SESSION['things'];
$ar_size=sizeof($ar)-1;
$break=false;
$i=0;
if($ar_size>=0)
 {
  while ($i<=$ar_size):
  $buf=$ar[$i];
   if($buf['id']==$_GET['thing']){$_SESSION['things'][$i]['count']=$buf['count']+1;$break=true;}
  $i++;
  endwhile;
 }
if($break==false){
$_SESSION['things'][($i)]=array('title' => $_GET['title'],
'id'=>$_GET['thing'],
'price'=>$_GET['price'],
'count'=>1);}
$modx->sendRedirect("/index.php?id=".$_GET['return']);


}
function _view()
{
if (!isset($_GET['zakaz'])){

session_start();
if(!session_is_registered('things')){session_register('things');}


if (isset($_GET['del']))
{
$buf=array();
$ar=$_SESSION['things'];
$ar_size=sizeof($ar)-1;
if($ar_size>=0)
 {  
  $i=0;
  while ($i<=$ar_size):   
    if(($i+1)!=$_GET['del']){$buf[sizeof($buf)]=$ar[$i];}
    $i++;
   endwhile;

}
$_SESSION['things']=$buf;

}
if (isset($_GET['delall']))
{
$_SESSION['things']=array();
}
if (isset($_GET['cn']))

session_register() and session_is_registered() are deprecated in PHP 5.3 and removed in PHP 5.4, according to the docs. I'd definitely take that out.

As OptimusCrime says, you can't use <?php and ?> in snippets; the ENTIRE snippet will be evaluated in parse time and doing that results in parse errors. May find some evidence of that in the error log.

Also all the references to session_start really shouldn't be there - MODX handles the sessions for you and you should not be re-starting them again. I'm not sure if that will cause issues, but if anything it can help to clear up your code even just a tiny bit ;)

You should put all your functions in:

If (!function_exists('yourfunction')) { [....]

EDIT: does your snippet work in a local modx install? Or does it work as a normal php-script? I dont think you can stop/start php (?> and

You could check your error-log within Modx. If it displays blank errors might be turned off
