PHP Form Question

[NoSalt]

Hello All

 

I have a question about form handling with PHP. Let's say I have a page named "questionnaire.php" and on that page I have a form. The form tag looks something like this:

 

    <form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">

 

Some one submits the form and if it is successful, they go to another page, say "thankYou.php".

 

Now here is my question. If that person hits the "Back" button in their browser (to go from thankYou.php back to questionnaire.php) they get the standard "you are trying to resubmit the form" warning. Is there any way to avoid this happening? Is there a way to not have the form try to re-submit when you hit the "Back" button?

 

Thanks everybody for reading

use header file to redirect the user and remove the post data

 

header('location: yourpage.php');

header('location: yourpage.php');

 

Interesting idea ... but how would you go about implementing this???

 

Thanks

Either after the php file has processed the information, or on the thankyou.php page.

 

Thats where i would do it

header(); needs to be sent to the browser before any other output. I'm not sure it would help anything, but it's worth a shot.

 

also, just a quick thing. the action attribute in your form tag could be empty and produce the same results. action will default to the current file so you really don't have to open php and echo PHP_SELF
