A variable is declared in index.php when the page loads (random number). When the user clicks on a link, I need to make a MySQL query with the variable. How would I do this?
When I ran the code with javascript ($.get("run.php");return false;) it doesn't recognize the variable.
I think I have to use Ajax but I just really dont know how that works, I just started PHP and MySQL a few days ago.
Help?
