they way you are doing it is pretty much the only way you can pass a variable to the javascript. make sure $groupname is returning a value.

also, try using <?php instead of <?

Are you sure it isn't working ? This code with slight modification to yours is working.
php Syntax (Toggle Plain Text) 
  1. <?php
  2. session_start();
  3.  $groupname = "test";
  4. echo $groupname;
  5. ?>
  6. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  7. <html xmlns="http://www.w3.org/1999/xhtml">
  8. <head>
  9. <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
  10. <script type="text/javascript">
  11.  
  12. var menu1=new Array()
  13. menu1[0]='<a href="employercp.php">Job Portal</a>'
  14. menu1[1]='<a href="cggroup.php?id=<?php echo $groupname; ?>">Groups</a>'
  15. document.write(menu1[0] + menu1[1]);
  16. </script>
I believe $groupname is empty in your case.

I don't really understand what your script does!
