When you submit the form, depending on the method specified in the form ("GET" or "POST"), the value will be in either the $_GET or $_POST arrays on the page to which you are submitting. You can retrieve the value by name (the name of the control):

$parentgroupid = $_GET['parentgroup'];

or

$parentgroupid = $_POST['parentgroup'];

When you submit the form (which presumably exists since you are referencing it from your JavaScript): Get the value from $_GET['name_of_form_control'] in the document referenced by the action attribute of the form.
