Background: I am trying to understand how the following scenario actually happens.
I am using colorbox.js a light box script and when a user clicks the <a class='ajax' href='edit_labor.php?edit_id=$id' title=''><span class='oi oi-pencil'>Edit</span></a> link in any of the table rows a lightbox should pop-up and a php page (located on the server) should load inside the light box.
This happens but the child PHP page edit_labor.php can not access any of the variables set on the parent page planned_labot.php. Just to test the scope of the child page I am actually able to add an include('functions.php'); in both the child page and the header of the parent page. Shouldn't I get errors from trying to load the same functions twice?
Question: I don't understand the parent child relationship between the loaded php page and the parent php page when jquery.colorbox.js loads it.
