Heya, Kaushal. Welcome to TSDN!

You posted this in the Articles section. I'll go ahead and move it to the Forum where an Expert will be more likely to find it.

Changed thread title to better describe the problem (did you know that threads whose titles that do not follow the Posting Guidelines actually get FEWER responses?).

Hi kiran Vidhate,

can you post the code you have already, it will make it simpler to assist if we can see what you have already.

Heya, Kaushal.

The way to prevent this is to use header() redirection. When the User submits the form, have the form submit to a *separate* page, and then use header() redirection to send him back when you are done.

How header() redirection works

At the top of the page, after you have processed the data, try this:

<?php 
session_start();
   if(isset($_REQUEST['bla']))
      {
          process the code here, then...
         echo "<script>
                  document.location.href='thispage.url';
                  </script>";
         exit;
      }
?>
 

This will process the data, then redirect the user to the same page, without the posted data.

You can also swap the JavaScript with a header, like pbmods said.
Like so:

header("Location: thispage.url");

Oooh I like that one... I have not found that!
I'll try it out on my site.
