foreach in controller codeigniter

我有以下问题，我正在使用Codeigniter，我在我的控制器的索引中做了一个小验证，这是代码：

function index()
    {
        $user = $this->session->userdata("id");
        $data = $this->customer_model->get_rol_user($user);

        foreach ($data as $row) {
          if ($row->Url === 'customer/index'){
               $this->load->view('guest/head');
               $this->load->view('guest/nav');
               $this->load->view('guest/section');
               $this->load->view('customer/customer_view');
            }
        }
        redirect(base_url());

    }

查询工作正常，我已经检查过，它返回我需要的是以下内容：

  • Url

  • 产品/指数

  • 供应商/指数

  • customer / index

如果在我的查询结果中我有与我的条件相同的值，如果，在这种情况下，如果是，我将不得不加载视图，否则我重定向到我的应用程序的主页，我在foreach失败？

这是我的模特：

function get_rol_user($user){

    $query = $this->db-> query("SELECT p.Url
            FROM User AS u INNER JOIN rol AS r ON u.fk_rol = r.id_rol
            INNER JOIN rol_page AS n ON n.fk_rol = r.id_rol
            INNER JOIN page AS p ON n.fk_page = p.id_page
            WHERE u.id_user ='".$user."'");
      if ($query->num_rows() > 0) {
        return $query->result();
    }
  }

    仅在设置了标志时添加标志并重定向（在我的示例中，它设置为 false ）：

    $load_view = false;
foreach ($data as $row) {
  if ($row->Url === 'customer/index'){
       // flag tells us that `if` is executed
       $load_view = true;
       $this->load->view('guest/head');
       $this->load->view('guest/nav');
       $this->load->view('guest/section');
       $this->load->view('customer/customer_view');
  }
}

// no Url is found - do a redirect.
if (!$load_view) {
    redirect(base_url());
}

    像这样..

    function index()
    {
        $user = $this->session->userdata("id");
        $data = $this->customer_model->get_rol_user($user);

        foreach ($data as $key=>$value) {
          if ($row[$key]->Url === 'customer/index'){
               $this->load->view('guest/head');
               $this->load->view('guest/nav');
               $this->load->view('guest/section');
               $this->load->view('customer/customer_view');
            }
         }
            redirect(base_url());

        }
