display data from database to dropdown CodeIgniter

I\'m having difficulty with display data from the db to dropdown.

This is what I have tried:

Model.php

        public funct

Codeigniter already has specialized functions that minimize the amount of html that you have to dump in your code:

Model

public function description_pulldown(){
    $this->db->from('location');
    $query = $this->db->get();
    foreach($query->result() as $row ){
        //this sets the key to equal the value so that
        //the pulldown array lists the same for each
        $array[$row->description] = $row->description;
    }
    return $array;
}

Controller

public function index(){
    $data['description_list'] = $this->delivery_model->description_pulldown();
    //load all of your view data
    $this->load->view('delivery_view', $data);
}

View

echo form_label("Description");
echo form_dropdown('description', $description_list, set_value('description'), $description_list);

If you need to have the view pull up the previous data in the dropdown list, you can do a foreach loop to obtain the previous value of the dropdown from the database ie... $description = $item->description; and in the view, change the 'set_value('description')' to simply '$description.'
