Aloha everyone out there! I've been searching around for hours, trying all different kind of $.ajax setups and all that.

But all i can get is an "Undefined index" error. At the moment, im using this while trying to pass the var from my script.js, to conInfo.php

$.ajax({
 url: 'conInfo.php',
 type: 'POST',
 data: {'data': 1},
 success: function (data) {
    console.log(data);
 }
});

And inside of my conInfo.php

<?php
 $value = $_POST['data'];
 echo $value;
?>

And this site is required within my index.php, with the connected script.js Thanks partypeople.
