I have a page “index.php” where i have a link called “add_users.php”. In “add_users.php”, I accept user information and come back to the same page “index.php” where information comes through post action and gets inserted into the database.
When I refresh the page or hit the back button, a resend box appears. I went through many solution where they asked me to create third page. I tried doing that as follows: after inserting values in database, I redirected the page as header(‘Location:http://thisisawebsite.com/thankyou.php, and in thankyou.php I again redirected the page to index.php. But this resulted in getting a warning as “Cannot modify header information – headers already sent by [….]”
What is a better solution?
Please use ob_start(); statement in first line itself.
