Solution

  • You'll need to add a <script> tag to your PHP file (e.g. WordPress template file), to add the global variable into javascript.

    For example:

    <script type="text/javascript">
    var idurl  = <?php $values = get_post_custom_values("Nalbums"); echo $values[0]; ?>;
</script>

    You can then use the JavaScript variable in your script.
