Deleting multiple records at once

Question

I am working on a 'private messages' page that displays a
listing of messages sent to the user (like an e-mail inbox). Each
message is a record in a database. I want to put a checkbox next to
each message on the page and a button to delete all checked
messages. How do I program the script to delete each message that
is checked?

Using PHP/MySQL, it's pretty easy. I'm assuming that each
message has a
unique id used as a primary key. All you need to do is output
the
checkboxes all with the same name attribute, including an
empty pair of
square brackets:
<input type="checkbox" name="d" value="<?php print
recordset['id'];?>">
In the script that processes the form submission, use
something like:
if(is_array($_POST['d'])){
$recs=join(',',$_POST['d']);
$query="DELETE FROM tablename WHERE id IN {$recs)";
mysql_query($query) or die(mysql_error());
The above assumes that the primary key mentioned is a numeric
value and
the field name is "id".
