So I have a html form and I have an URL where it will be submitted, say the URL is www.myformsubmit.com/form_submit.php. This form_submit.php will give me a text saying if everything is correct in the form or prints out an error message.

What I want to do is that to do is that after the form is submitted to form_submit.php I want to redirect users to a thank you page. My question, is there a way to do this without having to touch the form_submit.php, if yes how?

With your current setup, you can't redirect to another page without modifying form_submit.php.

You can have the form submit to itself, and then do something like this:

<?php
    // Optionally, also make sure that there are no errors.
    if (isset($_POST["SomeInputValue"])):
    {
        // Must be BEFORE any output is sent!
        header("Location: /thank_you.php");
    }

    else
    {
        // Display the form page.
    }
?>

You want to check if everything is fine from form_submit.php but you do not want to post data to it? I think this is really not possible.

The short answer would be no. To correctly answer your question we need to know why you cannot modify form_submit.php. This is because a simple line of code could be added to redirect to a "thank you" page when the form is correctly filled in.
