Accessing URL Parameters - Simple question

    For the life of me I cannot find where there is information on how to access parameters on the URL. A simple $_Get won’t retrieve anything. So I’m assuming MODx is grabbing it and storing it somewhere. However, I can’t find documentation for where that is.

    Can someone point me in the right direction? Here’s an example URL:

    http://www.somewhere.com/special/catalog/?desig=123456

    Thanks!

      Not sure what was going on, but $_GET is working now. Oh well. smiley

        Hi, i’m new with modx and i have your same problem.
        I want call snippet with parameter &tpp and value $_GET[’c’], where c is URL parameter
        for example: ( http://localhost/modx-1.0.2/index.php?id=47&c=vita ).

        I call snippet test in this mode: [[test? &tpp=`$_GET[’c’]`]]
        but do not work.

        can you help me?

          Here is the simplest snippet example :
          <?php
$output = '';
$output .= $_GET['c'];
return $output;
?>

            Using the example link you provided above, try this as yout Test snippet and see if it helps:

            <?php
/*    testsnippet
      usage: call uncached
      [!testsnippet!]

*/
$output ='';
$tpp = isset($_GET['c']) ? $_GET['c'] : 'tpp not found';

$output .='<p>tpp: '.$tpp.'</p>';

return $output;
?>

                A slightly different variation on the previous responses:

                <?php
/**
 * MY_GetQueryStringValue
 *
 * DESCRIPTION
 *
 * This snippet returns a value from a query string
 *
 * USAGE:
 *
 * [[!MY_GetQueryStringValue? &field=``]]
 */

return isset($_GET[$field]) ? $_GET[$field] : '';

                  -->

                  This doesn't work!

                  It has to be:

                  return isset($_GET['field']) ? $_GET['field'] : '';
