Re: [PHP] Can I retrieve a stored php session variable from within a javascript function?

Thanks for your advice.
 I've heard of this technique before but wanted to know if there was
another way to do it from Javascript.

Regards 
Mauricio

 No. You cannot retrieve it, restore it, read it, send it, anything else.
 
 You can write it from PHP :
 
 echo 'script type=text/javascriptvar sess = 
 '.$_SESSION['somevar'].'/script';
 
 But that's it.

 I'm no PHP expert, but I'll give it a try (there are plenty of smart 
 people on this list who will correct me if Im wrong :-)
 
  Does anyone have any ideas about this?
 
 Yes, two of the top of my head.
 
 1. You can send the session variable to the client along with the script.
 
 ex.
 function doSomething()
 {
sessVar = ?php print($_SESSION['variable']); ?;
 
// Do some stuff.
 }
 
 Of course, sessVar won't be updated if the session variable changes 
 unless the script is reloaded.
 
 2. My favorite, but probably overkill. Write a php page that outputs 
 the session variables (as XML would be cool). Then use xmlhttprequest 
 to retrieve them from javascript (Google AJAX for more information).
 
 Hope this helps,
 Rick
