Simple AJAX PHP Post request?

Question

Hi there coders of treehouse!

I'm fairly experienced in quite a lot after about 10 months of constant coding and time with treehouse but I'm struggling to find a solid example out there for what I'm after.

E.g. All i want to be able to do is POST the value of a searchbox ONKEYUP to a seperate PHP file that can store the POSTED variable.

I would give you some example code but in my frustration i scrapped it all and thought I would try again some other time.

I can't use a GET method at all for this and I can get AJAX to send a request and get a simple echo from the PHP file but whatever i put into the input won't store into a variable when posted with AJAX. I thought i would put this question under PHP because it's the post/variable thats the problem not so much the Javascript.

Many thanks,

Adam

Your code would be helpful, but ...

Debugging AJAX can be a bit of a pain. What I try is usually something like:

    <?php
        echo json_encode($_POST);
    ?>

You didn't talk about the Javascript code that's making the request, but make sure the request method is POST and then console.log the response. In jQuery this would be

    $.ajax({
        method: "POST",
        dataType: "JSON",
        success: function(data) {
            console.log(data);
        }
    }

If you're PHP is firing back what you send to it, all you need to do is do something with that data.
