I want to pass data array 'myWorkout' to "play_workout.php". I want "play_workout.php" to open and display the contents of 'myWorkout' (for this example).
(Once I see that this is working I will parse the data from myWorkout and write it back to a database).

I'm not getting any errors in firebug, but play_workout.php is not being opened nor is it capturing array 'myWorkout'.

Please advise if you've accomplished something like this. Thanks as always!

page workout_now.php

HTML Code:
<div id="playworkout"><button onClick="playWorkout()">Play Workout</button></div>
JAVASCRIPT

Code:
function playWorkout(){

  var arr = $("#dropTargetframe > li").map(function(){
  return $(this).attr('data-id');}).get();

     var myRoutine = arr;
     var myWorkout = new Array();
        for (var i in myRoutine){
           if (myRoutine[i])
             myWorkout.push(myRoutine[i]);
            }
          //array appears like ["4", "5", "1", "4"]
          JSON.stringify(myWorkout);
          encodeURIComponent(myWorkout);

         var url = "http://localhost/RealCardio/play_workout.php";

         $.get(url, myWorkout);
page play_workout.php

PHP Code:
<?php
 
...
 
$arrayWorkout json_decode($_REQUEST['myWorkout']); 
 
print_r($arrayWorkout);     
...
?>
