Well thanks so much delayedinsanity for your help, I figured out why it was not working in the first place, I had the log in form pointing to the wrong file... so when I changed it to the correct one it executed perfectly. Once again thanks.
Also I do have another question about my front controller. It works perfectly when I point it to a file I have made, and it also works when a page cannot be found but I cant figure out how to make it have a default page to display for my index.
Example:
If I go to a page that exists like
http://localhost/rome/index.php?page=user&action=login
Then it loads it up perfectly.
And when I go to a page that doesn't exist like
http://localhost/rome/index.php?page=free&action=money
it displays the 404 error page like it should...
So the question is when I want it to point to the main index file
http://localhost/rome/index.php
How do I get it to load up a default home page when someone goes to the index.php? Because all I get from it is my 404 error page.
index.php
PHP Code:
<?php
define("CONTROLLER_DIR", dirname(__FILE__) . "/app/controller");
define("MODEL_DIR", dirname(__FILE__) . "/app/model");
define("PAGE_DIR", dirname(__FILE__) . "/app/view/pages");
