This is really weird..

I need to send a couple of variables through to jquery from PHP.. one is an INT and the other a string.

When $a is an INT it works fine but when i use a string, i get this error.. Uncaught ReferenceError: testString is not defined

Here is my code.

<?php $a = 'testString'; ?>

<script type="text/javascript">
    var a = <?php echo $a; ?>;
    alert(a);
</script>

I assumed that i needed to stick a (int) or (string) before the variable, but i wasn't entirely sure how to and unsuccessful in my googles/attempts.

Any ideas?

You forgot the quotes to make the value of var a a string:

var a = "<?php echo $a; ?>";

What you're writing into the document is:

var a = testString;

so javascript is looking for a variable called testString. Instead, you want the result to be:

var a = "testString";

so make sure you include the quotes around what php is writing in.

There are quotes missing in javascript code:

<script type="text/javascript">
  var a = '<?php echo $a; ?>';
  alert(a);
</script>
