PHP Checkbox complication..!

Hi guys,
even i’m confused with this one but i’ll try my best explaining how it works…

  1. display a list of checkbox based on the data in db…
  2. on submit, navigate to the confirmation page
    the checked items should be verfied if they are already contained in the db, if they are, then ignore them… if they’re not, then obviously add these items, after user confirms… this part works fine…
    …what doesnt seem to work is the removal…
    …in page 1, when the checkboxes are displayed, if value already exists, i precheck the item… users have the option to uncheck these items (meaning…remove it from the db)…when this info is passed to the confirmation page, i cant seem to locate the item that got ‘unchecked’ so that i can delete it… only the checked items’ info are passed thru :frowning:
