查看

              public function shopped()
              {
              $config['upload_path'] = './application/assets/images/shops';
              $config['allowed_types'] = 'jpg';     
              $this->load->library('upload', $config); 
              $id=$this->input->post('shop_name');
              $type=$this->input->post('type');
              $this->form_validation->set_error_delimiters('<div class="error" style="color:red">', '</div>');
              $this->form_validation->set_rules('shop_name','Business Type','required');   
              $this->form_validation->set_rules('type',' shop type','required|alpha');
              if ($this->form_validation->run() == FALSE) 
              {
                   $this->viewcategories();
              }
              else if (!$this->upload->do_upload('userfile'))
              {
                    $error = array('error' => $this->upload->display_errors());
                    $this->viewcategories($error);
              }
              else
              {
                    $data = array('upload_data' => $this->upload->data());
                    $this->businesstype_model->getshop($id,$type);
                    $success_message='Successfully Added!';
                    $this->session->set_flashdata('success_message',$success_message);
                    redirect(base_url().'admin/businesstype/viewcategories');   
               }
             }

viewcategory功能

         public function viewcategories()
       {   
          $nam=$this->input->post('name');
          $rec=$this->businesstype_model->getdata();
          $rec_array=array('rec_name'=>$rec);
          $this->load->view('admin/header',$rec_array);    
          $this->load->view('admin/addshop_view',$rec_array);
          $this->load->view('admin/footer',$rec_array);   
      }

我想在addshop_view

上显示错误消息

如果条件不起作用，则在我的其他地方出现错误消息。该原因是什么..

psp给出了一个建议..

Answer 1

尝试将其放入addshop_view

// Report all PHP errors 
error_reporting(E_ALL);

或者

// Report all PHP errors
error_reporting(-1);

错误消息未显示图像上载
