Stumped on passing a string - SOLVED

[Antivirus]

I've been able to pass form variables between different scripts within admincp with no problem, however I am trying to use different branches within the same script (as I should), but this has really got me stumped and I can't see what i'm doing wrong here. If anyone can help, i'll do a little dance or something...

Data is submitted through a form with multiple events on each line and each line has a checkbox:

<input type=\"checkbox\" name=\"idsforaction[]\" value=\"" . $event['eventid'] . "\">

Here's how I am sending the eventids to the remove branch...

PHP Code:

$strIDs = implode(",", $_POST['idsforaction']);
header("Location:scst_eventsmanager.php?" . $vbulletin->session->vars['sessionurl'] . "do=remove&eventids=".$strIDs); 


Now i have echoed the location string above before calling the header function and it shows just as it should, for instance:
Location:scst_eventsmanager.php?do=remove&eventids =6,3,4,5

But when the remove branch is executed, the eventids never seem to pass. Here's my remove branch:

PHP Code:

if ($_REQUEST['do'] == 'remove')
{
    $vbulletin->input->clean->gpc('g', 'eventids', TYPE_STR);
    
    $sql = $db->query_read("
        SELECT eventid, eventdate AS date, eventdescription AS title
        FROM " . TABLE_PREFIX . "scst_event
        WHERE eventid IN '" . $vbulletin->GPC['eventids'] . "'
    ");

    print_form_header('scst_eventsmanager', 'kill');
    construct_hidden_code('idforaction', $vbulletin->GPC['eventids']);
    print_table_header($vbphrase['confirm_deletion']);
    while ($delevent = $db->fetch_array($sql))
    {
        $deleventdate = vbdate($vbulletin->options['dateformat'], $delevent['date'], 1);
        print_description_row("
        <blockquote><br />
        " . construct_phrase($vbphrase["are_you_sure_want_to_delete_event_x"], $deleventdate, $delevent['title'], $delevent['eventid']) . "
        <br /></blockquote>\n\t");
    }
    print_submit_row($vbphrase['yes'], '', 2, $vbphrase['no']);
} 


Now for some reason, it doesn't seem to pass the eventids to the remove branch. If it did, I woudl see the info for each of them in the confirmation box's description rows which are printed for each event I am about to delete, correct?

If I ever get past the remove branch, my kill branch looks like this:

PHP Code:

if ($_POST['do'] == 'kill')
{
    // to delete event
    $db->query_write("DELETE FROM " . TABLE_PREFIX . "scst_event
        WHERE eventid = " . $vbulletin->GPC['idforaction']
    );
    // to delete event's associated staffnotes
    $db->query_write("DELETE FROM " . TABLE_PREFIX . "scst_staffnotes
        WHERE eventid = " . $vbulletin->GPC['idforaction']
    );

    define('CP_REDIRECT', 'scst_eventsmanager.php?do=modify');
    print_stop_message('event_has_been_deleted');
} 


Thanks!
