I’ve done this many times in JavaScript, but now I want to do it in php and ONLY php. My code now can select all the options from the DB and display the first list's options, but I don’t know how to check if the first choice was made so I can display the second list's options accordingly. Thank you for your help. (Copy Shortcut)
