登录后如何显示管理员全名的名称 - Codeigniter

Question

I am having a trouble on displaying my admin's full name, like for example admin full name is John Doe, it is not displaying. I am still learning codeigniter please give me advice thank you!

here is my controller

            //Get username
        $username = $this->input->post('username');

        //Get and encrypt the password
        $password = $this->input->post('password');

        // Login user
        $user_id = $this->role_model->login($username, $password);


        if ($user_id) {
        // Create session
        $user_data = array(
            'user_id' => $user_id,
            'name' => $user_id->name,
            'username' => $username,
            'logged_in' => true
        );

        $this->session->set_userdata($user_data);

        //Set message
        $this->session->set_flashdata('user_loggedin','You are now logged in');

        redirect('pages/index');

here is my View - where I would like to display my full name, as you can see 'name' is the data field I have to display but it is does not show anything, it gives an error that says name is not defined.

  <li><a> Welcome, <?php echo $this->session->name ?> </a></li>

Model

        public function login($username, $password){
        //Validate
        $this->db->where('username',$username);
        $this->db->where('password',$password);

        $result = $this->db->get('users');

        if ($result->num_rows() == 1) {
            return $result->row(0)->id;
        }else{
            return false;
        }
    }

Answer 1

Your method login() returns only id = digit (return $result->row(0)->id;), not object (in controller your get $user_id->name).

Do this, in the model:

if ($result->num_rows() == 1) {
    return $result->row(0); // fix
}else{
    return false;
}

In the controller:

$user = $this->role_model->login($username, $password);

$user_data = array(
    'user_id' => $user->id, // fix
    'name' => $user->name, // fix
    'username' => $username,
    'logged_in' => true
);
