wtf are you smoking Jack? every checkbox that was checked will exist in the
$_POST array set with the value you gave it (I alway set a chekcboxes value to 1
because the values mere existance in the submitted data indicates it's chevckbox
was checked), if a checkbox does not exist in the $_POST array it wasn't checked!!!
imagine you have 10 checkboxes named 'cb1' thru 'cb10' each with a value of '1',
upon submitting the form they are in, your script sees the following in the $_POST
array...
$_POST = array('cb1' => '1', 'cb9' => '1', 'cb10' => '1');
which tells you 3 checkboxes were checked... namely 'cb1', 'cb9' and 'cb10'
now how hard is it to determine which we're not checked?
maybe I'm not seeing the problem but I get the impression that you are
over complicating things regarding checkbox.
