However, like someone else said, if you named your checkboxes as box[1],
box[2], etc, then you'd have a nice $_POST['box'] array that you could
loop through.
foreach($_POST['box'] as $count => $value)
{ do_whatever($count); }

RE: [PHP-DB] checkboxes and loops
I am relatively new with PHP, but have done this many times with ASP.
First, I would not assign the counter value to the checkbox as you are now.
Use the ID (identity) value from the database for the applicant record
instead. Since ONLY the checkboxes that are checked will be submitted, you
can just loop through the submitted checkbox values and perform a 'delete',
or 'whatever' on each submitted record. Or, use: "...WHERE IN (id1, id2,
..., idN)" in your DELETE statement.

Re: [PHP-DB] checkboxes and loops
Hi!
I think you should rename checkboxes to box[1], box[2] etc.
So you will get an array $_POST["box"]. I think it will be better.
Best wishes,
