On a series of web forms users needs to be able to move forwards and backwards. However I want to process the form irrespective of which direction they are going.
The buttonshave name of “submit” and values of “back” and next”. How do I interpret the value?
This doesn’t work 🙂
if(isset($_POST[$submit['back']])) { header('location: ../pages/create_page1.php'); }
if(isset($_POST[$submit['next']])) { header('location: ../pages/create_page3.php'); }
The the name of the field is called
submit, so you need to check if the field has been submitted and what its value is:However you aren’t using submit buttons, you are using server side image maps, so the value might not have been submitted (depending on the browser).
Instead you need to give the fields different names, and then check to see if co-ordinates were sent for those fields.
