 * I called a Hook from the order received page and want to collect the JS data 
   from user and pass it back to PHP to use the variable.
 * I tried to call with:
 *     ```
       <script>
             jQuery.ajax({
             type: "POST",
             url: window.location,
             data: { test:"test" },
             success: function( data ) {
               alert(data);
             }
           });
       </script>
       ```
   
 * and this to get
 * `echo $_POST['test'];`
 * but it is not working, the data is successfully posted but PHP cant read the 
   variables.
    Anybody know how to do it? Thanks for your help

 * Have a read through this:
 * [https://codex.wordpress.org/AJAX_in_Plugins](https://codex.wordpress.org/AJAX_in_Plugins)
 * Basically, you need to set up an AJAX handler in your site that will be able 
   to work with that variable.
