Question

I would like to display thank you message after adding comment only for the first page load… The comment form is processed using an external php file and than redirected back to the page. I would like to display some message after the redirection only… What would be the best way to do this using php?

Answer 1

Assuming you have access to the external php file that processes the file you could do something similar to the following on the processing file:

$_SESSION['flashMessage'] = 'Thank you for posting.';
header("Location: your-page.php');

And then add the following to the redirect page:

if ($_SESSION['flashMessage']) {
    echo $_SESSION['flashMessage'];
    $_SESSION['flashMessage'] = NULL;
}
