Looks like your importData.php is returning invalid JSON, so we'd need to see that file or at least the output of it to give you a proper answer.

OK. I've not gone through your entire code, but the first problem I see is on line 8:

if($_POST['importSubmit'])

You are making the AJAX call using GET, not POST so line 8 will throw an error. Either change your PHP script to deal with a GET request, or change your AJAX call to make a POST request.

Soon after that you have this line:

echo $message;

So immediately, you're outputting something that isn't JSON. Later on, you do this:

print($res);

Again - more output that isn't JSON

Finally, you do attempt to output some JSON which is simply:

"successfully"

I would strongly suggest turning on error reporting and then try loading the script page (importData.php) directly in the browser before trying to call it using AJAX. That way you will see any errors directly in your browser. Once you know that's working, then you can deal with the AJAX side of things.
