Question

How can put return tow function following in one function marge() and echo it with json_encode.

 function get_gr()
{
            //$tourf_id = $this->input->post('toname');
            $id = '102';

            $query = $this->db->order_by('id','desc')->get_where('table1', array('id' => $id));
            if ($query->num_rows() == 0) {
                return 0;
            } else {
                $query = $query->row();
                return array('guide' => $query->guide);
            }
}

function get_res()
{
            //$id   = $this->input->post('name');
            $id = '102';
            $data = array();
            $query_r = $this->db->order_by('id','desc')->get_where('table2', array('relation' => $id));
            if($query_r->num_rows() > 0){
                foreach ($query_r->result() as $row) {
                    $data[] = array(
                                            'name_re' => $row->name_re,
                                            'id' => $row->id
                                        );
                }
                return $hotel_data;
            }else{
                return 0;
            }
}
function marge(){
    echo json_encode(get_gr().get_res()); //This line 991
}

I get this erroe from above php code:

Fatal error: Call to undefined function get_gr() in D:\xampp\htdocsapplication\controllers\faile.php on line 991

What do i do?

Answer 1

If inside a controller, you must refer to get_gr() as $this->get_gr()
