... and here is the model to go with the controller

MODEL

Code:

<?php
class Contacts_model extends MX_Model {

    function Contacts_model()
    {
        parent::MX_Model();
          $this->default_table = 'contacts';        
    }
    
    function add_contact( &$form, $data )
    {
        // called by the "contacts/add" form whenever (pre-validated) data is posted to it
        
        // verify the posted contact name (firstname + lastname) does not already exist
            $rules = array( 'firstname' => $this->input->post('firstname'),
                            'lastname' => $this->input->post('lastname') );
            if( $this->get_row($rules) )
                return $form->add_error('contact_id', 'This contact already exists!');    
        
        // prepare (the posted data) for database insert
            unset($data['add']); // form submit button (not a database field / object property)
            $data['updated_by_user_id'] = $this->session->userdata('user_id'); // not part of the form
        
        // write new record to the database
            return $this->create($data);
    }
    
    function edit_contact( &$form, $data )
    {
        // the "contacts/edit/" form calls this function when data is posted to it

        // TBD - don't let a user change a contact name to the name of an already existing contact because contact names (firstname + lastname) are unique
        // see if the posted contact_id identifies a unique record
        $rules = array( 'contact_id' => $this->input->post('contact_id') );
        if( $this->get_row($rules) == false )
        {
            return $form->add_error('contact_id', 'No such contact to edit!');    
        }
        
        // prepare (the posted data) for database update
        unset($data['edit']); // form submit button (not a database field / object property)
        $data['updated_by_user_id'] = $this->session->userdata('user_id'); // not part of the form
        
        // update the contact_id record with validated form $data
        return $this->updater($data,$rules);        
    }

}
?>

This single view file supports calls from each of index and add and edit

VIEW

Code:

<div id="content" class="main">
    <div id="container">
        
        &lt;!-- insert left side-bar navigation for this page --&gt;
        <div id="navadminID">
            &lt;?php $this->load->view('nav_side'); ?&gt;
        </div>

        <div id="mainID">
            <div id="content" style="clear:both;">
                    <br>
                    
                    <h2>&lt;?php echo $heading; ?&gt;</h2>
                    
                    &lt;?php
                        // optional heading button
                        if( isset($button) ) echo "<p id=\"goback_button\">".$button."</p>";
                    
                    // show flash data
                        echo '<p style="color:red">'.$this->session->flashdata('success').'</p><br>';
                        
                    // show the form
                        if( isset($form) )
                        {
                            $this->load->view('form');
                        }
                    // or else show the list of records for this report
                        else
                        {
                            $this->load->view('contact_report');
                        }
                    ?&gt;    
            </div>
        </div>&lt;!-- // end #mainID --&gt;
        
    </div> &lt;!-- // end #container --&gt;
</div>  &lt;!-- // end #content --&gt;

I hope it helps somebody.

If any experts can take a look, any feedback would be appreciated.
