I want to send a Javascript array to PHP using AJAX. This seems very simple code, but I am getting the "No isset" message. 

<?php 

if (isset($_REQUEST['activitiesArray'])) {
echo 'YES isset';   
}else{
echo 'No isset';
}
?>

<!DOCTYPE html>
<html>
<head>

<script  src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">


var activities = ["thing1", "thing2", "thing3"];

$.ajax({        
   type: "POST",
   url: "JavatoDBase.php",
   data: { activitiesArray : activities },
     success: function() {
     $("#lengthQuestion").fadeOut('slow');        
     }
 });

Safari displays the following, which suggests the POST is operating

what happens when you dump the whole request back to client? –  charlietfl Jun 19 '12 at 1:21

Look into the request which data is actually submitted and how. –  hakre Jun 19 '12 at 1:26
 
Did you try posting a json instead of an array? –  Eswar Rajesh Pinapala Jun 19 '12 at 1:30
 
Thanks guys. I did try sending a small text string, but same error message. Also. The PHP is in the same file as the javascript i.e. "JavatoDBase.php" so I don't think I'm calling another PHP function –  Jeremy Jun 19 '12 at 1:33

If you make an ajax request, you should return something that you can use in the js to determine how it went. You also only want to load the response, not the entire page html and all.

Try this:

<?php 

if (isset($_REQUEST['activitiesArray'])) {
  echo json_encode(
    array('status' => true)
  );
  exit(0);
}else{
echo 'No isset';
}
?>

<!DOCTYPE html>
<html>
<head>

<script  src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">
  var activities = ["thing1", "thing2", "thing3"];

  $.ajax({        
    type: "POST",
    url: "test.php",
    data: { activitiesArray : activities },
    dataType: 'json',
    success: function(data) {
      if(data.status === true) {
        alert('rad');
      }
      else {
        alert('bad');
      }
    }
  });
</script>

I found the answer. All the above code was help is the PHP file (I started with PHP and HTML followed). I then split the PHP into its own (PHP suffix) file and the HTML into its own (HTML suffix) file. It worked like a charm. Thanks for your help.
