I get an error message that says:
"A PHP Error was encountered
Severity: Notice
Message: Undefined property: Register::$register_model
Filename: controllers/register.php
Line Number: 52

Fatal error: Call to a member function register_insert() on a non-object in D:\EasyEclipse Projects\iFitIgniter\system\application\controllers\register.php on line 52"

What does it mean to have a "Call to a member function register_insert() on a non-object"?

I am doing a registration page.
I have 3 things: a model, a view, and a controller.
The controller loads the view and the model.
The connection to the db works great. The view pages loads correctly and shows what it should. I then fill in the fields (name, email, etc.) BUT when I click submit I get the error.

Will some one please explain what the error means and how to fix it???
Thanks in advance.

Here is the CONTROLLER code.

Code:
class Register extends Controller {

    public $fields = array('firstname','lastname', 'email', 'screenname', 'password');

   function index()

    {

        parent::Controller();

        $this->load->model('register_model');

        $this->load->library('validation');

        $rules['firstname'] = "trim|required|min_length[5]|max_length[12]";

        $rules['lastname'] = "trim|required";

        $rules['eamil'] = "trim|required";

        $rules['screenname'] = "trim|required";

        $rules['password'] = "trim|required|valid_email";

        $this->validation->set_rules($rules);

        $fields['firstname'] = 'firstname';

        $fields['lastname'] = 'lastname';

        $fields['email'] = 'email';

        $fields['screenname'] = 'screenname';

        $fields['password'] = 'password';

        $this->validation->set_fields($fields);

        /*

         *

          if($this->validation->run() == False)

        {

            $this->load->view('register_view');

        }else{

            $this->load->view('');

        }

        */

        $this->load->view('register_view');

    }

    function register_insert()

    {

        $this->load->database();

        //$num_rows =

        $this->register_model->register_insert();

        //$data['num_rows'] = $num_rows;

        $this->load->view('register_view.php');

    }

}

Here is the VIEW code

Code:
&lt;html&gt;

&lt;head&gt;

    &lt;title&gt;&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

    &lt;?=$this->validation->error_string; ?&gt;

    &lt;?=form_open('/register/register_insert');?&gt;

        First Name:

        &lt;input type="text" name="firstname" value="&lt;?=$this-&gt;validation->firstname;?&gt;" size="20" />&lt;?=$this->validation->firstname_error; ?&gt;<br />

        Last Name:

        &lt;input type="text" name="lastname" value="&lt;?=$this-&gt;validation->lastname;?&gt;" size="20" />&lt;?=$this->validation->lastname_error; ?&gt;<br />

        Email:

        &lt;input type="text" name="email" value="&lt;?=$this-&gt;validation->email;?&gt;" size="20" />&lt;?=$this->validation->email_error; ?&gt;<br />

        Choose a Screen Name:

        &lt;input type="text" name="screenname" value="&lt;?=$this-&gt;validation->screenname;?&gt;" size="20" />&lt;?=$this->validation->screenname_error; ?&gt;<br />

        Password:

        &lt;input type="password" name="password" value="&lt;?=$this-&gt;validation->password;?&gt;" size="20" />&lt;?=$this->validation->password_error; ?&gt;<br />

        &lt;input type="submit" name="submit" value="Register Now"&gt;

    &lt;/form&gt;

&lt;/body&gt;

&lt;/html&gt;

Here is the MODEL code

Code:
class Register_model extends Model  {

    public $firstname = '';

   public $lastname = '';

   public $email = '';

   public $screenname = '';

   public $password = '';

   public $signupdate = '';

        function register_model()

        {

        parent::Model();

        $this->load->helper('form');

        }

       function register_insert()

         {

        $this->firstname = $_POST['firstname'];

        $this->lastname = $_POST['lastname'];

        $this->email = $_POST['email'];

        $this->screenname = $_POST['screenname'];

        $this->password = $_POST['password'];

$sql_query = "INSERT INTO DB ("

                . " EMAIL,"

                . " FIRSTNAME,"

                . " LASTNAME,"

                . " SCREENNAME,"

                . " PASSWORD"

            . " ) VALUES ("

                . " ?,"

                . " ?,"

                . " ?,"

                . " ?,"

                . " ?"

            . " )";

        }

 }

You need to load the model in the register_insert() function in your controller.

[quote author="Negligence" date="1202427382"]You need to load the model in the register_insert() function in your controller.[/quote]

where do I put it?
I tried it at the top of the function right after the opening bracket {. I also tried it at the bottom of the function just before the closing bracket }. Neither place seems to work.
Am I calling it incorrectly?

Code:
function register_insert()

    {

$this->load->model('register_model');

        $this->load->database();

        $this->register_model->register_insert();

        //$data['num_rows'] = $num_rows;

        $this->load->view('register_view.php');

$this->load->model('register_model');

    }

you need a constructor for your controller, like you have for the model

Code:
class Register extends Controller {

  function Register() {

    parent::Controller();

  } // Register()

...

That did it... it works now.
Thank you for your help.
