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!!!Oh, how I wish I were smoking something :) !
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?Well, for me, it is - because I don't know the names of the other check boxes which were not checked because they were dynamically created, and I don't have the knowledge sufficient to pass the NAMES of all checkboxes through to $_POST so that I can search through and see which have been answered and which ones not.
maybe I'm not seeing the problem but I get the impression that you are over complicating things regarding checkbox.As always this is hugely possible. JJ
