in my current application, once a user logins in they are redirected to their dashboard, via the dashboard.php controller. currently residing at www.myproject.com/dashboard

now from this page there is a link to modify settings. once clicked they are then routed to www.com/dashboard/settings - this function from within the dashboard controller loads a view file...

Code:
$template['mainContent'] = $this->load->view('dspSettings', $data, true);

        $this->load->view('layDash', $template);

now from the dspSettings view file there is a form. im using the ci form helper. the form is as follows...

Code:
&lt;?=form_open('dashboard/updateUserAccount'); ?&gt;

        <label for="modify_oldpassword">Old Passsword</label><br />

        &lt;input  type="password" name="password_old" id="modify_oldpassword" value="" /&gt;<br />

        <label for="modify_newpassword">New Passsword</label><br />

        &lt;input  type="password" name="password_new" id="modify_newpassword" value="" /&gt;<br />

        <label for="modify_confpassword">Confirm New Passsword</label><br />

        &lt;input  type="password" name="password_conf" id="modify_confpassword" value="" /&gt;<br />

        <label for="modify_firstname">First Name</label><br />

        &lt;input  type="text" name="firstname" id="modify_firstname" value="" /&gt;<br />

        <label for="modify_lastname">Last Name</label><br />

        &lt;input  type="text" name="lastname" id="modify_lastname" value="" /&gt;<br />

        <label for="">Delete Account?</label><br >

        &lt;input type="checkbox" value="0" id="modify_deleteaccount" /&gt;<label for="modify_deleteaccount" class="selectable">Check here to delete your account.</label><br />    

        &lt;input type="submit" value="Modify Settings" /&gt;

    &lt;/form&gt;

on submission, the form routes to the dashboard/updateUserAccount function:

Code:
function updateUserAccount(){

        $data['title'] = "My Finance ~ v1.00 ~ Dashboard";

        $data['status'] = "PLEASE LOGIN";

         $rules['password_old'] = 'trim|required';

          $rules['password_new'] = 'trim';

          $rules['password_conf'] = 'trim';

          $rules['firstname'] = 'trim';

          $rules['lastname'] = 'trim';

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

        $template['mainContent'] = $this->load->view('dspSettings', $data, true);

        $this->load->view('layDash', $template);

        if($this->validation->run() == FALSE){

                $data['status'] = "Invalid Login";

                redirect('/dashboard/settings/', 'refresh');

        } else {

            $password_old = $this->validation->password_old;

            $password_new = $this->validation->password_new;

            $password_conf = $this->validation->password_conf;

            $firstname = $this->validation->firstname;

            $lastname = $this->validation->lastname;

//DISREGUARD BELOW THIS LINE

//HAVENT GOT THERE YET

            if ($this->userAccountHandling->modifyUserAccount($password_old, $password_new, $password_conf, $firstname, $lastname)) {

                $data['title'] = "My Finance - v1.00";

                $data['status'] = "USER ACCOUNT FOUND - LOGGING IN";

                //USER ALREADY EXISTS

                //LOG USER IN

                if ($this->userAccountHandling->loginTheUser($emailaddress, $password) == TRUE) {

                    //successful login

                    //$this->load->view('layMain');

                    redirect('/dashboard/', 'refresh');

                }

            }

        }

    }

the current url is www.com/dashboard/updateUserAccount which brings up errors telling me 'Undefined property: password_new' because that field was submitted empty. how can i keep the field optional and still modify a record in the database without running into errors like this.

im still new to the framework and developing in general. how is my structure. could i be doing these easier and faster? thanks.

Update your model method, placing the optional parameters at the end and defining default values. Something like this:

Code:
function updateUser($username, $password, $email, $new_password = '') {

}

So, when you call that function - if you fail to define the 4th parameter it will default to ''

this issue arises when i submit the form and call the dashboard/updateUserAccount...when it gets tothe else statement, these lines are throwing errors.

Code:
$password_old = $this->validation->password_old;

            $password_new = $this->validation->password_new;

            $password_conf = $this->validation->password_conf;

            $firstname = $this->validation->firstname;

            $lastname = $this->validation->lastname;

the errors are..
Message: Undefined property: password_old
Message: Undefined property: password_new
...and so on for all 5.

ive also updated my model function with your suggestion. but my script is failing before it even gets there.

I guess your assumption is wrong that the validation object has such a property. It "only" has the rules assigned fro the fields it should check.
See http://ellislab.com/codeigniter/user-guide/libraries/validation.html

So why do you not take the values from your original array?

Have you checked the $_POST array?

Try setting the fields' names - I think that will allow you to use $this->validation->var_name (as well as prettying up your error messages).

Code:
$field['password_old'] = 'old password';

$field['password_new'] = 'new password';

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

Ok, i have a new idea on how to handle my logins / new registrations. upon coming to the site the default controller is welcome.php from here there is one form which submits a post array, containing an email address and a password, to the welcome/checkUser method is my welcome controller. this method checks to see if the submitted email address is already taken. if it is, redirect users to the welcome/doLogin method, if its not taken, redirect users to the welcome/doRegister method. and while inside welcome/doRegister, once the registration has returned from the model, i want to redirect users to the welcome/doLogin method to be automatically logged in. im having the hardest time getting things to work.

Code:
function checkUser(){

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

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

        $validUser = $this->User_model->checkEmailExists($this->validation->emailaddress, $this->session->userdata('session_id'));

        if($validUser){

            $this->doLogin();

        } else {

            $this->doRegister();

        }

    }

Code:
function doLogin(){

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

        $this->load->helper( array('url', 'form', 'date') );

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

        $user_id = $this->User_model->login($this->validation->emailaddress, $this->validation->password, $this->session->userdata('session_id'));

        if($user_id != 0){ 

            // succsessful login

            $this->session->set_userdata(array('user_id' => $user_id));

            $data['user'] = $this->User_model->getDetails($user_id);

            $data['title'] = "My Finance - v1.0 ~ Dashboard";

            redirect('/dashboard/overview', 'refresh');

            //$template['mainContent'] = $this->load->view('dspDashboard', $data, true);

            //$this->load->view('layDash', $template);

        } else {

            // login failed

            $data['title'] = "My Finance - v1.0 ~ Home";

            //redirect('/welcome', 'refresh');

            $template['mainContent'] = $this->load->view('dspHome', $data, true);

            $this->load->view('layMain', $template);

        }

    }

Code:
function doRegister(){

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

        $this->load->helper( array('url', 'form', 'date') );

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

        $user_id = $this->User_model->register($this->validation->emailaddress, $this->validation->password, $this->session->userdata('session_id'));

        if($user_id > 0){

            // successful registration

            //$this->doLogin();

            $user_id = $this->User_model->login($this->validation->emailaddress, $this->validation->password, $this->session->userdata('session_id'));

            if($user_id != 0){ 

                // succsessful login

                $this->session->set_userdata(array('user_id' => $user_id));

                $data['user'] = $this->User_model->getDetails($user_id);

                $data['title'] = "My Finance - v1.0 ~ Dashboard";

                //redirect('/dashboard', 'refresh');

                //$template['mainContent'] = $this->load->view('dspDashboard', $data, true);

                //$this->load->view('layDash', $template);

            } else {

                // login failed

                $data['title'] = "My Finance - v1.0 ~ Home";

                //redirect('/welcome', 'refresh');

                $template['mainContent'] = $this->load->view('dspHome', $data, true);

                $this->load->view('layMain', $template);

            }

        } else {

            // failed registration            

            $data['title'] = "My Finance - v1.0 ~ Home";

            redirect('/welcome', 'refresh');

        }

    }

now my question is how can i pass my $data variable when using a redirect. because all of this is taking place in my welcome controller. so once someone logs in, they are taken to the dashboard controller. if i uncomment the redirect lines and using the load->view my url stays www.com/welcome/home instead of www.com/dashboard.
