I'm learning how to integrate JQuery, AJAX and PHP together.
My problem is that my success function isn't getting any value from the parameter and just getting a '0'. I'm not really sure what I'm doing wrong either, but I have just been following this tutorial JQuery & PHP Tutorial and just copied how he got the value from the PHP code using echoes and a parameter variable r.
I have tried searching for the solution, but I'm not sure if any of the results are relevant to what I am doing. I tried following some of their advice but none seems to work (the promise thing for jQuery)
I hope someone can enlighten me what I am doing wrong as I am eager to learn more PHP and jQuery.
