Try to get PHP session user into JavaScript

Question

I am trying to get the user session from a PHP script into jQuery, but the result is empty. If I use the code in a PHP script it is working properly.

How can I make this work?

<script>
jQuery(document).ready(
   function(){
       var user = '<?php echo $_SERVER['LOGON_USER']; ?>';

       alert(user);
       $('#answer83148X78X346').val(user);
   }
);
</script>

The code should work fine. The problem must be in a different part of your application — hek2mgl

Probably, instead of $_SERVER['LOGON_USER'] you should try to use $_SESSION['LOGON_USER']. — NikitaBaksalyar

What happens if LOGON_USER contains a single quote, I wonder? ) — raina77ow

yep, @raina77ow is right. use addslashes($_SESSION['LOGON_USER']) — hek2mgl

@hek2mgl Actually, I meant something like... var user = <?= json_encode($_SESSION['LOGON_USER']) ?>;. — raina77ow

You might want first try to check whether the variable you're using is correct by logging an output of $_SESSION['LOGON_USER'] or whatnot. In this case, you can easily do this by checking the resulting HTML page's source code.

Also, when serializing values for JavaScript you should escape them to prevent XSS attacks - i.e., filter value through htmlspecialchars function - or better serialize it as JSON, because it handles all types of values, not only strings.

here is my solution:

i created a authuser.php with the following code:
then i retrieved via jquery.get the result from authuser.php and set the textfield with this data:

$( document ).ready(function() {

$.get("authuser.php", function(data) {
alert("Data Loaded: " + data); $('#answer83148X78X346').val(data); });
