Hi ,
I wonder if it's possible to retrieve the value from a php session
variable from within a javascript function.
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
