Form Validation w/ submit to new page
Posted: Sun May 14, 2006 9:06 pm
Hey all,
I've been doing a lot of searching for an ability to validate a form. I have found several examples that have the php form validation with the php code on the same page as the form, which is what I would like. However, ALL of these examples simply post back to themselves wether an error is found or not...What I need to be able to do is to go to post the form data to a new page if all of the form data is valid. Does this make senes? Simply put "Bad form data ==> self with error message and sticky form, Good form data ==> post form data to new page"
Below is one of the examples that I have found, but that always posts back to itself, could somebody please help me with this issue?
