Each photo has a checkbox. Once that checkbox is checked, a div, containing numerous select menus, toggles to show. The numerous select menus are for choosing a quantity of various sized prints of that pic (e.g. 4"x6", 5"x7", etc.).
With the way I'm processing the form now, the do/while loop is running through the photos where the album equals the album_id. It is checking each pic to see if all of the select boxes are left blank. If at least one of the select menus has been changed, it processes that info.
Am I going about that the wrong way. Sorry if that is still vague. I've never made a form quite this extensive before.
