Problem with using global variables in php is that they lose the the assigned value in a different php file. They only keep the global variable value in the php file in which they are declared.
Instead of globals try and use $_SESSION or $_COOKIE to keep value intact across different php files in a project

There are many things that can stop your variables from passing between your forms and your php scripts. One common reason is that your php configuration file is not configured to pass your form variables as globals, and instead passes them through the $_GET and $_POST superglobals. So, for example, if you form is as such: <form method="post"> <input name="whatever"> </form> Your php script would access the variable $whatever through the $_POST superglobal. $whatever = $_POST['whatever'];
