$this->db->escape() vs $this->db->escape_str()

Code:

function create(){

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

        // field name, error message, validation rules

        $this->form_validation->set_rules('name', 'Title', 'trim|required|min_length[4]|xss_clean');

        $this->form_validation->set_rules('autoplayon', 'Autoplay ON', 'trim|required');

        $this->form_validation->set_rules('autoplayoff', 'Autoplay OFF', 'trim|required');

        if($this->form_validation->run() == FALSE)

        }

        else

        {            

            $data = array(

            'name' => $this->input->post('name'),

            'slug' => url_title($this->input->post('name'),'dash', TRUE),

        }

Code:

function add_record($data){

        // insert 

       $this->db->insert('radio', $this->db->escape($data));
