How do I use input cleaner to clean arrays?

[Antivirus]

the following code works fine for me using straight php, however when i try to get it to work using the vbulletin input cleaner, it just posts "array" into the responses field and wipes out the submittes results:

here's what's working for me using "non-vb" php:

PHP Code:

foreach ($_POST['whatyoudid'] as $feedbackdetailid => $whatyoudid)
{
    $db->query_write("
        UPDATE scst_feedbackdetail SET 
            whatyoudid = '" . addslashes($whatyoudid) . "', 
            responses = '" . addslashes($_POST['responses'][$feedbackdetailid]) . "',
            comments = '" . addslashes($_POST['comments'][$feedbackdetailid]) . "'
        WHERE feedbackdetailid = '" . $feedbackdetailid . "'
    ");
} 

i tried to clean it as follows but no dice:

PHP Code:

    $vbulletin->input->clean_array_gpc('p', array(
        'feedbackdetailid'    =>    TYPE_UINT,
        'whatyoudid'        =>    TYPE_STR,
        'responses'            =>    TYPE_STR,
        'comments'            =>    TYPE_STR
    ));

foreach ($db->escape_string($vbulletin->GPC['whatyoudid']) as $feedbackdetailid => $whatyoudid)
{
    $db->query_write("
        UPDATE " . TABLE_PREFIX . "scst_feedbackdetail SET 
            whatyoudid = '" . $whatyoudid . "', 
            responses = '" . $db->escape_string($vbulletin->GPC['responses'][$feedbackdetailid]) . "',
            comments = '" . $db->escape_string($vbulletin->GPC['comments'][$feedbackdetailid]) . "'
        WHERE feedbackdetailid = '" . $feedbackdetailid . "'
    ");
} 

I just need to figure out how to clean the two arrays above... $_POST['responses'][$feedbackdetailid] and $_POST['comments'][$feedbackdetailid]

can anyone save me from bloody torment?

ok i figured it out... thanks to Alan's HOWTO on the input cleaner class...

this works for me:

PHP Code:

$vbulletin->input->clean_array_gpc('p', array(
    'whatyoudid'    =>    TYPE_ARRAY_STR,
    'responses'    =>    TYPE_ARRAY_STR,
    'comments'    =>    TYPE_ARRAY_STR
));

foreach ($vbulletin->GPC['whatyoudid'] as $feedbackdetailid => $whatyoudid)
{
    $db->query_write("
        UPDATE scst_feedbackdetail SET 
            whatyoudid    = '" . $db->escape_string($whatyoudid) . "', 
            responses    = '" . $db->escape_string($vbulletin->GPC['responses'][$feedbackdetailid]) . "', 
            comments    = '" . $vbulletin->GPC['comments'][$feedbackdetailid] . "'
        WHERE feedbackdetailid    = '" . $feedbackdetailid . "'
    ");
}
