Code:

public function pages($id = false)
    {
        if($id)
        {
            $query = $this->db->query("SELECT * FROM myTable WHERE myKey='".$id."'");
            $data['pages']= $query->result();
            $data['prm']  = '';
            $data['mode'] = 'pages';
            $this->load->view('template',$data);
        }
        else
        {
            // Do something
        }

    }

What do you thing about this ?

You can set an default value (in this case false). Then you check the value by an if statement.[/quote]

Hi Fireclave, thanks for your post ...
It work well, now that i can redirect to other page while found an empty $id.
To CI_adis i've read it

Code:

note that this is just not in codeigniter but throughout php in case you were wondering

I thought that i should learn more about php function
Thanks for you all
