How to load a View based on multiple conditions in Controller (Codeigniter) - php

Question

I'm new to codeigniter. I'm trying to make a simple site, with three (3) conditional views.
For example:
If "user_agent" detects mobile device -> load mobile_view
else load -> web_view
and if "site" settings is disabled [value = 0] load -> maintenance_view
I have the following code but doesn't work. It always load the maintenance view.
Controller:
function index() {
$this->load->library('user_agent');
if($this->agent->is_mobile())
{
$this->load_mobile();
} else {
$this->load_web();
}
}
public function load_web() {
$site = $this->Datamodel->getsetting();
if(isset($site) && $site==1) { //check if site settings is enabled [(if site "value == 1" load -> web_view) ELSE (site "value == null" load -> maintenace_view)]
$this->load->view('web_view');
} else {
$this->load->view('maintenance_view');
}
}
public function load_mobile() {
$this->load->view('mobile_view');
}
Model for site settings:
function getsetting() {
$this->db->select("site");
$this->db->from('configuration');
$query = $this->db->get();
$ret = $query->row();
return $ret->site;
}
For site settings conditions, I have extendted my old code from here How to load a view based on condition in Controller (Codeigniter)
The previous code only have 2 conditions if site is enabled [site value == 1] or not [site value == null]
Depending on conditions, web or index view is loaded in controller if site "value == 1" otherwise if site "value == null" load the maintenace view
Now Im trying to add a mobile view, but I cant figure it out how, with the rest of the code.

Answer 1

function index() {
if(site_value == 0){
$this->load->view('maintenance_view');
}else{
$this->load->library('user_agent');
if($this->agent->is_mobile())
{
$this->load_mobile();
} else {
$this->load_web();
}
}
}
