Question

What is the best way to create my model so I can call it from my controller like this?

$this->model_model->function->dbname

I have the following model but its rubbish:

Model:

function systemName()
{

    $query = $this->db->query("SELECT cms_name FROM options");

    return $query->result();
}

Update:

function systemOptions($options)
{   
    $this->db->select($options);

    $query = $this->db->get('options');

    return $query->num_rows();
}

Answer 1

Why would you want to? Why not call it like this?:

 $this->model_model->functionname('dbname');

A complete skeleton of a model is like this:

<?php
class Mymodel extends Model
{
    function get_some_entries($number_rows)
    {
            return $result = $this -> db -> query("SELECT id, name
                                            FROM tablename
                                            LIMIT $number_rows");
    }
}
?>
