PHP comment page on refresh asks to send data again - dont want - $_POST

[shortysbest]

I have a comment page that people can add a comment to the page on my website. If you submit a comment and then refresh the page i get this message:

"to display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."

 

If you click resend it posts the same comment again, obviously dont want that. How can i reset the $_POST or whatever so it doesnt do this?

Once you have successfully added the comment to your database (or however you store them), redirect the user using the header function.

You could do it by including a hidden field in your form,

<input type="hidden" name="control" value="true" />

Then...

On your page that you want to be able to refresh, include

<?php
//any headers or session_start() statements that you have go here.
if(isset($_POST['control'])){
//The Rest Of Your Current Page Code Goes Here
unset($_POST['control]);
}
else{
//only the part of your code that displays the page info, not the part that processes the form gets repeated in here
}
?>

 

And see how that goes.

if (!empty($_POST)) {
  //process
  if ($insertSuccess) {
    header('Location: ' . $_SERVER['SCRIPT_NAME']);
    exit(0);
  }
}

 

After the user submits the form you process it, and you redirect them to the same page. If you now refresh the page FF does not asks you.
