[PHP] Delete Multiple Records From Checkboxes

[Albert Padley]

I've checked the archives and several other sources, but still can't 
seem to make this work.

I have a form with checkboxes to designate records to be deleted from 
the mysql database. The pertinent form code is:

<input type=\"checkbox\" name=\"del[]\" value=\"" . $row['id'] . "\">
The processing code is:
if (count($del) > 0){
        for ($i=0;$i<count($del);$i++){
        
                $query = "DELETE FROM ref_events_reg WHERE id = '$del[$i]'";
}
}
Echoing the query produces:
DELETE FROM ref_events_reg WHERE id = A
I've also tried the following:
$query = "DELETE FROM ref_events_reg WHERE id IN ('" . implode("','", 
addslashes($del)) . "')";

This one produces a warning:
Warning: implode(): Bad arguments.
and the following query:
DELETE FROM ref_events_reg WHERE id IN ('')
Both attempts fail to delete any records even though several records 
are checked.

Where have I gone wrong?
Thanks.
