I have checked How do I redirect to another webpage? and though they do successfully redirect, they remove the echo 'OK' function I have implemented.
I have a form and would like to redirect back to the home page 5 seconds after the form has been submitted.
However, there needs to be an echo first that says "OK" which links to a jQuery script and shows a green box that says "Your message has been sent (<div class="sent-message">). Thank you!". I would like to display that for 5 seconds, before redirecting back to the home page.
I know you cannot use header("Location: http://www.yourwebsite.com/index.html"); after echo but is there another way to do this?
This is what the form looks like when it is successfully submitted. The green box is what echo 'OK'; does. https://ibb.co/BjZ9v47

<?php
// script to send myself an email with the data entered into the form by a user
if($mail->Send()) {
echo 'OK';
// redirect to index.html after 5 seconds
}

Answer 1

You can echo a <meta> refresh with a set URL, although this isn't the best approach.
if (!$mail->Send()) {
echo "Mail sending failed";
}
else {
echo "Mail sent!";
echo "<meta http-equiv='refresh' content='5;URL=/index.html'>";
}
More information about the meta tag here.

Answer 2

In your $.ajax done callback, inside if you can use setTimeout:
if (msg == 'OK') {
this_form.find('.loading').slideUp();
this_form.find('.sent-message').slideDown();
this_form.find("input:not(input[type=submit]), textarea").val('');
//redirect to specific url after 5secs
window.setTimeout(function () {
window.location.href = 'https://www.example.com'; //your home url here
}, 5000);
}
