My final in my PHP class is due tomorrow, and I have it pretty much done, aside from one vital issue. But no one's answering my plea for help on the school's forums. The project is a registration form for users to input their information directly into a database. After submitting the data, it's optional for the user to view all the users in the database. And that's where I'm having issues. The page to view all users is getting the Fatal error: Fatal error: Call to a member function getfirst_name() on a non-object in /home/a4238680/public_html/labs/labFinal/view/list_all.php on line 15.

Here is my web page, and here is the page I get the error on. I have way too many files to put all of the code here, but I'll display the code for list_all.php and the file that has the functions, registrant.php, and include the complete file set and structure in an attached file.  labFinal.zip (7.44K)

Wherever this $users object

<?php foreach ($users as $user) : ?> 

gets populated, it's not getting populated properly.

$user_information = new Registrant($row['user_id'], $row['first_name'], $row['last_name'], $row['email'], $row['gender']);
		$user_information->setUser_id($row['user_id']);

If you're passing the user_id to the Registrant constructor, why would you need a separate call to setUser_id?

I must've put it in by mistake! Whoops. However, omitting the code does not effect the issue.
