登录验证在CodeIgniter中不起作用

Question

您好，所以我在CodeIgniter中构建了一个登录系统，在允许访问特定页面之前，数据库应满足3个验证步骤。

三个步骤的值是：active，is_member和is_admin

这是我在Users控制器中创建的代码：

public function login(){
    // Prohibit access if already logged in
    $this->User_model->session_comprobate_member();

    $this->form_validation->set_rules('username','Username','trim|required|min_length[4]');
    $this->form_validation->set_rules('password','Password','trim|required|min_length[4]');


    if ($this->form_validation->run() == FALSE){
        //Load View Into Template
        $this->template->load('public','login','users/login');
    } else {
       // Get Post Data from Database
        $username = $this->input->post('username');
        $password = $this->input->post('password');
        $enc_password = md5($password);
        $data_user = $this->User_model->login($username, $enc_password);

        if($data_user == true){
            $user_id = $this->User_model->get_userid($username);
            $users   = $this->User_model->get_username($user_id);

            if($users->active == 0){

            // Create error
            $this->session->set_flashdata('error', 'This account is banned or inactive');

            // Redirect to page
            redirect('dashboard/login');

            }

            if($users->is_admin == 0){

            // Create error
            $this->session->set_flashdata('error', 'You do not have permission to view this page');

            // Redirect to page
            redirect('dashboard/login');

            }

            if($users->is_member == 0){

            // Create error
            $this->session->set_flashdata('error', 'This account does not exists. Please try again.');

            // Redirect to page
            redirect('dashboard/login');

            } else {
            $sess_data = array(
                'user_id' => $user_id,
                'username'  => $username,
                'occupation' => 'occupation',
                'is_member' => true,
                'is_admin' => true,
                'active' => true
            );

            // Set Session Data
            $this->session->set_userdata($sess_data);

            // Create Message
            $this->session->set_flashdata('success', 'You are logged in');

            // Redirect to pages
            redirect('dashboard');
            }
        } else {
            // Create Error
            $this->session->set_flashdata('error', 'Invalid Login');

            // Redirect to pages
            redirect('dashboard/login');
        }
    }
}

根据用户帐户，这些值中的每一个都设置为TRUE(1)或FALSE(0)。我有一个树的值等于1的帐户，所以它应该允许我访问;这是一张图片：我想要的是在登录验证满足三个值之后允许访问但是出于某种原因甚至在将用户全部设置为TRUE之后如果只是一直让我抛出我创建的第一个错误：

$this->session->set_flashdata('error', 'This account is banned or inactive');

知道怎么解决吗？谢谢。

这是我的模型：

    public function get($id)
    {
        $this->db->where('id', $id);
        $query = $this->db->get($this->table);
        return $query->row();
    }    
public function login($username, $password)
    {
        $this->db->select('*');
        $this->db->from($this->table);
        $this->db->where('username', $username);
        $this->db->where('password', $password);
        $this->db->limit(1);

        $query = $this->db->get();

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

    //I need to work on these two
    public function get_username($users) {
        $this->db->select('id');
        $this->db->from($this->table);
        $this->db->where('username', $users);
        return $this->db->get()->row;
    }

    public function get_userid($user_id) {
        $this->db->select('id');
        $this->db->from($this->table);
        $this->db->where('id', $user_id);
        return $this->db->get()->row();
    }
    ///
    //Check if admin
    public function is_admin($id) {
        $this->db->select('is_admin');
        $this->db->from($this->table);
        $this->db->where('id', $id);
        $is_admin = $this->db->get()->row('is_admin');
        if ($is_admin == 0) {
            redirect('/');
        } else {
            redirect('admin');
        }
    }

    //Check if member
    public function is_member($id) {
        $this->db->select('is_member');
        $this->db->from($this->table);
        $this->db->where('id', $id);
        $is_member = $this->db->get()->row('is_member');
        if ($is_member == 0) {
            redirect('/');
        } else {
            redirect('dashboard/login');
        }
    }

    //Check if active
    public function is_active($id) {
        $this->db->select('active');
        $this->db->from($this->table);
        $this->db->where('id', $id);
        $is_active = $this->db->get()->row('active');
        if ($is_active == 0) {
            redirect('/');
        } else {
            redirect('dashboard/login');
        }
    }

再一次感谢你的帮助。
