I don't know how to access array values with $vbulletin->GPC[]

[Oreamnos]

I am doing a multiple row update so my html looks like:

<input type="text" name="$image[ws_id]ws_order" value="$image[ws_order]">

and then:

PHP Code:

$vbulletin->input->clean_array_gpc('r', array(
    'ws_order' => TYPE_ARRAY,
));

// we also need to update the information
    $update_rows = $db->query_read("
        SELECT * FROM table
        WHERE id = '" . $db->escape_string($info['id']) . "'
        ORDER BY ws_order ASC
    ");

    // update list
    while ($do_update = $db->fetch_array($update_rows)) {
        
        $order = $_POST[$do_update['ws_id']."ws_order"];
        $update_title_directions = $db->query_write("
            UPDATE table
            SET ws_order = " . $db->escape_string($order) . " 
            WHERE ws_id = " . $db->escape_string($do_update['ws_id']) . "   
        ");
        
    } 


as is, this works fine but i'd like to replace the $_POST[] with $vbulletin->GPC[] but when i try it's empty and creates an error.

my guess is that its not being read in the clean_array_gpc function, though im not sure. if that is the problem, is it possible to tag something like 'ws_order[]' => TYPE_ARRAY, into the function?

if not, what can i do?
