Open the browser's developer tools and look at the network tab to see what your AJAX call is sending to PHP. – Jay Blanchard Jul 31 '20 at 14:34
you dont need `''` around data in your ajax call – Baracuda078 Jul 31 '20 at 14:34
But it doesn't hurt anything @Baracuda078 – Jay Blanchard Jul 31 '20 at 14:36

@JayBlanchard ok, didn't know that. I was learned to not use them – Baracuda078 Jul 31 '20 at 14:37
@JayBlanchard yes in response tab it shows the value – ceeejeey Jul 31 '20 at 14:43
If `$_POST['data']` is undefined that means that you did not send a value with your AJAX call. – Jay Blanchard Jul 31 '20 at 14:52
