Stop form refresh

[Mutley]

Is there a method to stopping a form refreshing? So when you submit a form, you can't hit refresh and submit the data again?

if the form submits data to a database you can always check to see if that data exists in the database onSubmit(), if it does do nothing, if not put it in or update it.

The best way is once the data has been entered, send it to another page via header("location"); that states it was updated, this will clear the post data from memory.

as frost mentioned, $_POST data is not only handled by php, but also by your browser. this makes it damn near impossible to remove $_POST data once it has been submitted.

I can redirect to another page, that's easy, just how can I display a confirmation message then?

<?php
//processing here
header("Location: http://www.yoursite.com/thankyou.php?msg=Thank you, we will get back to you ASAP!");
?>

 

thankyou.php

<?php
print $_GET['msg'];
?>

 

Just like that =)

Hehe, yeah I just did it like that.

 

Thanks for the help.
