You can use

PHP Code:

$vbulletin->input->clean_gpc('p', 'postnamehere', TYPE_STR(INT,ARRAY etc); 


or

PHP Code:

$vbulletin->input->clean_array_gpc('p', array(
'postname1' => TYPE_****,
'postname2' => TYPE_*** )); 


You can then use

PHP Code:

$vbulletin->GPC['postnamehere'] 


to show the value.

Hope thats clear
