Having Issue on Getting Second Session Variable in JavaScript

Question

I have a PHP file getting data from my SQL database and I am trying to set and get two session variables like $_SESSION['fname'] and $_SESSION['userID'] by $theFName and $theId.

       $email = $_POST['email'];
       $pass  = $_POST['pass'];
       $conn = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_DATABASE);                
       $sql = "SELECT id, email, fname, lname, type FROM users WHERE `email`=? AND `pass`=?";              
       $stmt = $conn->prepare($sql);
       $stmt->bind_param('ss', $email,$pass);
       $stmt->execute();
       $stmt->bind_result($theId,$theEmail,$theFName,$theLname,$theType);
       if ($stmt->fetch()) {
            echo 'true';
            $_SESSION['LOGIN_STATUS'] = true;
            $_SESSION['fname'] = $theFName;
            $_SESSION['userID'] = $theId;
       } else {
            echo 'false';
        }

in JavaScript file I have

 <script>  
  var tok = "var UID = "<?php echo $_SESSION['userID']; ?>"; 
  console.log("The Id is " + UID)
</script>

but I am getting empty string!

can you please let me know what I am doing wrong?

...in all files using sessions? Error reporting will tell you http://php.net/manual/en/function.error-reporting.php while making sure the JS code is in a `.php` file. — Funk Forty Niner, Nov 21 '15 at 18:41
I won't stand here all day, I have better things to do than wait around like someone's personal butler. Good luck, I am moving on. — Funk Forty Niner, Nov 21 '15 at 18:48
Thanks for reply , yes I have started the Session on the all pages — Behseini, Nov 21 '15 at 19:15
I am in fact using the `$_SESSION['fname'] = $theFName;` in the HTML and working (So Session and Database query ar3 working properly!) but in JavaScript not working! — Behseini, Nov 21 '15 at 19:20

I'm not quite sure I understand what you are trying to do in the JS file, but it is not valid JS in any case - the quotes don't match and it seems like you are trying to do an assignment inside a string.

I think what you are looking for is something more along the lines of this:

<script>  
  var UID = "<?php echo $_SESSION['userID']; ?>"; 
  console.log("The Id is " + UID)
</script>

However, please note that dynamically generating JS files using PHP is likely not the best way to go about this. Check out this SO answer on the various methods you can use to pass variables from PHP to JS, along with their various pros and cons.
