Codeigniter更新记录错误

Question

我正在使用codeigniter框架，当我提交发布到我的数据库时，我一直收到此错误。

控制器

public function profilePic()
  { 
    if ($this->session->userdata('userLogin')) {
      $user_id = $this->session->userdata('user_id');
        $data = array();
         if (isset($_POST['add'])) {

            $pic = $this->input->post('profileFace');
            $front = $this->input->post('frontView');
            $left = $this->input->post('leftView');
            $right = $this->input->post('rightView');
            $back = $this->input->post('backView');

            $updtResult = $this->main_model->updateProfilePic($pic,$front,$left,$right,$back,$user_id);
                redirect("userProfile");
        } else {

          $data['userdata'] = $this->main_model->getUserData();
             $this->load->view("frontend/ajax-view", $data);
        }
    } else {
        redirect("/fitness");
    }
  }

模型

function updateProfilePic($pic,$front,$left,$right,$back,$user_id) {

  $check = $this->getUserData();
   if(count($check)!=0)
   {


      if($pic != "")
      {
       $data['image'] =  $pic;
      }
      if($front != "")
      {
        $data['front_view'] = $front;
      }
      if($left != "")
      {
        $data['left_view'] = $left;
      }
      if($right != "")
      {
        $data['right_view'] =$right;
      }
      if($back != "")
      {
        $data['back_view'] = $back;
      }

     // pr($data);

      $this->db->where('user_id',$user_id);
      $result = $this->db->update('fitness_users', $data);
    }

     return $result;
}

我得到的错误是：

您可以使用 private void setupDrawerContent(NavigationView navigationView) { navigationView.setNavigationItemSelectedListener( new NavigationView.OnNavigationItemSelectedListener() { @Override public boolean onNavigationItemSelected(MenuItem menuItem) { if (menuItem.getItemId() == R.id.tab_11) { mViewPager.setCurrentItem(0); } else if (menuItem.getItemId() == R.id.tab_22) { mViewPager.setCurrentItem(1); } else if (menuItem.getItemId() == R.id.tab_33) { mViewPager.setCurrentItem(3); } else if (menuItem.getItemId() == R.id.setting_nav) { Intent nextIntent = new Intent(getApplicationContext(), settingActivity.class); startActivity(nextIntent); } mDrawerLayout.closeDrawers(); return true; } });方法更新数据，并使用set

检查您的变量是否已设置

isset()
