Newbie Needs help

[eluser]nagata[/eluser]
So I made a reg form with all the model, view, controler stuff
And when I was done doing so I started testing.
When I press Submit I get this error:

Code:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Auth::$db

Filename: libraries/Form_validation.php

Line Number: 954

Fatal error: Call to a member function limit() on a non-object in C:\xampp\htdocs\system\libraries\Form_validation.php on line 954

So can someone help me?
If source of app needed, I can give it if needed.

Looks like you might be using a validation rule that requires the database, like is_unique. Is your database configured, loaded and working correctly?

Yes, code always helps.

I had been making this code 3 hours...
Anyways yes DB is configured properly, I was following that tutorial in manual and all worked right...

I figured some mistakes out on my own, but i met this...

Code:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Auth::$auth_model

Filename: controllers/auth.php

Line Number: 47

Fatal error: Call to a member function insert_user() on a non-object in C:\xampp\htdocs\application\controllers\auth.php on line 47

insert_user() is a function in auth_model, and is used in reg()

Edit,

So yeah I used my brains and worked hard and finnaly fixed this problems

Ps. I removed the code as it contained some of the security methods...
