specific controllers allowing query strings

[eluser]xwero[/eluser]
It's a php error. You can't add an array as a value of a constant. So you have to work with

Code:

define('MY_GET',$_SERVER['QUERY_STRING']);

To get the key value(s) out from the string you can use this function

Code:

function get_pairs($key='')
{
   parse_str(MY_GET,$pairs);
   // all pairs
   if(empty($key))
   {
      return $pairs;
   }
   // some pairs
   if(is_array($key))
   {
      $keys = array_keys($pairs);
      $output = array();
      foreach($key as $k)
      {
         if(in_array($k,$keys))
         {
            $output[$k] = $pairs[$k];
         }
      }
      return $output
   }
   // a pair value
   if(isset($pairs[$key]))
   {
      return $pairs[$key];
   }
}

Another solution based on the same constant is to repopulate the GET global with the constant after the input class cleaned the globals. The pre_controller hook is best suited for this.
