Submit Data....

NZ_Kiwis

I have a form.. when a user submits it, it goes to a page process.php and the end of this script I do this

header("Location: index.php");

to take them back to the index however if they refresh the page it submits the data again... how can i stop this?

Only thing I can think of would be to place a refresh link directly on the page, or tell the PHP code to insert a redirect inside the <head> area once the form submits.

I don't think this is the best way to do it but you can use sessions.

So add this before header

$_SESSION['Form_Submit'] = true;
header("Location: index.php");

Then wherever you don't want the user to send data again use this

 if ( isset($_SESSION['Form_Submit']) )
{
exit('You\'ve already submitted this form.');
}
