How to handle eror message in controller ? - El Forum - 08-13-2011

Hi Everybody, i have a problem with my controller programs.
Here's my code :
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Home extends CI_Controller {
function __construct(){
session_start();
parent::__construct();
}
public function index()
{
//load config file
$this->load->model('conf');
$setting = $this->conf->webconfig();
$query = $this->db->query('SELECT * FROM myTable WHERE FrontPage="1"');
$data['prm'] = '';
$data['date'] = $setting['date'];
$data['home'] = $query->row();
$this->load->view('template_1',$data);
}
public function pages($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);
}
}It will display error message and disturb the website display when people visit http://www.mysite.com/home/pages/ without insert a value for $id
And my question now, How to handle an empty $id, so that it will not display an error message ?

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.

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
Thanks for you all
