Codeigniter admin and user role - php

Question

I'm making a login system with 2 roles one for 'admin' and one for 'user'. I tried to make a else if statement for the login. This for the user login actually what happens now that every user is going to the admin_view right now.
In my database the row is called 'admin' which is a boolean so if the column 'admin' is 1 in the users table. The admin_view should be loaded if the value is 0 the user_view needs to be loaded.
I really don't know what to do now.
How do I need to seperate the roles between the admin and user?
Here is my controller: users.php
public function login() {
$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[3]');
$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[3]');
$this->form_validation->set_rules('confirm_password', 'Confirm Password', 'trim|required|min_length[3]|matches[password]');
if ($this->form_validation->run() == FALSE) {
$data = array(
'errors' => validation_errors()
);
$this->session->set_flashdata($data);
redirect('home');
} else {
$username = $this->input->post('username');
$password = $this->input->post('password');
$user_id = $this->user_model->login_user($username, $password);
if($user_id) {
$user_data = array(
'user_id' => $user_id,
'username' => $username,
'logged_in' => true
'admin' => 1;
);
$this->session->set_userdata($user_data);
$this->session->set_flashdata('login_success', 'You are now logged in');
$data['main_view'] = "admin_view";
$this->load->view('layouts/main', $data);
}
// Here I want the user_view to load op if the user haa a 0 value in
in the column admin.
else if($user_id) {
$user_data = array(
'user_id' => $user_id,
'username' => $username,
'logged_in' => true,
'admin' => 0;
);
$this->session->set_userdata($user_data);
$this->session->set_flashdata('login_success', 'You are now logged in');
$data['main_view'] = "user_view";
$this->load->view('layouts/main', $data);
} else {
$this->session->set_flashdata('login_failed', 'Sorry, you are not logged in');
redirect('home/index');
}
}
}
Here is my model: user_model.php
public function login_user($username, $password) {
$this->db->where('username', $username);
$result = $this->db->get('users');
$db_password = $result->row(2)->password;
$admin = $result->row(7)->admin;
if(password_verify($password, $db_password)) {
return $result->row(0)->id;
} else {
return false;
}
}
}
I apperciate the help.

First off, there is a typo in your array, the last one should not end with a ;.
In your user_model, instead of returning the ID, return some more information.
eg:
return $result->row(0);
Then, when you go back to your controller, you can do
$data = $this->user_model->login_user($username, $password);
array(
'user_id' => $data->id,
'username' => $username,
'logged_in' => true,
'admin' => $data->admin
);
From there, you could check in the session data whether admin is 0 or 1.
Then you can do :
if ($admin == 0) {
//send to wherever
} else {
//send some place else
}
