Good day, guys! I'm currently developing a website and the problem is when I refresh the page it will prompt a confirm form resubmission. How can I solve this issue? thank you in advance.
Welcome to the world of HTML form validation!
The most common solution to this problem is, once the form data has been validated and processed, issue a header command to show the confirmation page.
if($bDataOK){
header('Location: http://example.com/page_ok_message.php');
exit;
}
else{
//Show the current form again with error messages
}
Put this near the top of you PHP before other output is sent, otherwise you'll get error messages about sending headers too late.
