I am developing a plugin and need to generate a blank page (load the page.php
from the current theme) and print custom content such as an HTML form or a message.
It should have a URL like http://example.com/?wpex_page=confirm
How can I display a page with the current theme's page.php and custom content in it?
EDIT (18 Jan 2012):
Found a better and simpler working solution: Generate a custom/fake/virtual Wordpress page on the fly
