Form validation and and doing redirects.

Anon

Hey People: I made a form validator script, it redirects you back to the page you were before if you have an error. To do this iam putting a hidden entry that is $REQUEST_URI . So if the script needs to redirect you back itll do this:
header("Location: ?$reference&message=another_message");
The problem with this is that the form is put as an include in many pages, some people access the page from index.php others from index.php?page=21 So if they are accessing it from plain index.php itll add a & (as you saw on the code) but i guess this is ok? or anybody know of a better way to do this?

Another problem I have noticed is if the person fills in the form, and then fills in the form again and make another error the query string will now look something like this:

http://www.domain.com/index.php?&msg1=The%20e-mail%20entered%20is%20not%20valid.%20Please%20Try%20Again.&msg1=You%20did%20not%20enter%20any%20feedback.%20Please%20Try%20Again.

There must be a simpler & more organized way to do this..

JP,
I usually make the target the same form you are using.

Then, based on the success of reviewing the form fields , do the redirect

if(everything is OK){
header(Location: \"whatever.php\");
}

Usually, I do form validation in a class, so that the php logic feeds the form variables to the class and receives \"OK\" or error indications.
