How to access PHP session variables from jQuery function in a .js file? In this code, I want to get "value" from a session variable

$(function() {
   $("#progressbar").progressbar({
      value: 37
   });
});

Hello,

You can produce the javascript file via PHP. 

Nothing says a javascript file must have a .js extention. For example in your HTML:

<script src='javascript.php'></script>

Then your script file:

<?php header("Content-type: application/javascript"); ?>

$(function() {
    $( "#progressbar" ).progressbar({
        value: <?php echo $_SESSION['value'] ?>
    });

    // ... more javascript ...

If this particular method isn't an option, you could put an AJAX request in your javascript file, and have the data returned as JSON from the server side script.
