如何在codeigniter中上传图片，错误号：1136

Question

1. 控制器 我希望用户可以在“bukti_trnsfr”列的“发票”或“订单”表中将图像上传到我的数据库 谢谢

           public function payment_confirmation($invoice_id = 0 )
           {   
           $data['get_sitename'] = $this->model_settings->sitename_settings();
           $data['get_footer'] = $this->model_settings->footer_settings();
           $config['upload_path'] = './uploads/';
           $config['allowed_types'] = 'gif|jpg|png';
           $config['max_size'] = '100';
           $config['max_width']  = '1024';
           $config['max_height']  = '768';
           $this->load->library('upload', $config);
           $this->form_validation->set_rules('invoice_id_input','Invoice id','required|integer');
           $this->form_validation->set_rules('amount_input','Amount Transfered','required|integer');
   
           if($this->form_validation->run()    ==  FALSE)
           {
               if($this->input->post('invoice_id_input'))
               {
                   $data['invoice_id'] =set_value('invoice_id_input');
               }else{  
                       $data['invoice_id'] = $invoice_id;
                       $upload_image = $this->upload->data();
                       $data_invoices = array(
                       'bukti_trnsfr'  => $upload_image['file_name']);
                   }
               $this->load->view('customer/form_payment_confirmation',$data);
           }else{
                   $is_valid = $this->model_customer->mark_invoice_paid_confirmed(set_value('invoice_id_input'),set_value('amount_input'),set_value('file_name'));
                   if ($is_valid)
                   {
                           $this->session->set_flashdata('message','Terima Kasih, Produk Yang Anda Pesan Akan Segera Kami Proses');
                           redirect('customer/shopping_history');
                   }else{
                           $this->session->set_flashdata('error','Jumlah Nominal Salah, Silahkan Coba Lagi ');
                           redirect('customer/payment_confirmation/'.set_value('invoice_id_input'));
                       }
   
                }
       }
   

2. 这是我的模型。 公共功能mark_invoice_paid_confirmed($invoice_id,$amount,$bukti_trnsfr) {//查看发票 $ret = 真； $data_invoices = $this->db->insert('invoices', $bukti_trnsfr); $is_invoice = $this->db->where('id',$invoice_id)->limit(1)->get('invoices'); if($is_invoice->num_rows() == 0 ) { $ret = $ret && FALSE;

               }else{//check the amount
   
   
   
                       $total = $this->db->select('SUM(qty * price) AS total')
                                         ->where('invoice_id',$invoice_id)
                                         ->get('orders');                
                       if($total->row()->total > $amount )
   
                       {
                               $ret = $ret && FALSE ;
                       }else
                       {//mark the invoice to PAID
                               $this->db->where('id',$invoice_id)->update('invoices',array('status'=>'confirmed'));
                           }
   
                    }
               return $ret;
           }
   

Answer 1

您忘记在代码中上传图片。在验证运行为 true 后，使用下面提到的行在 codeigniter 中上传图像。

$this->upload->do_upload('file_name');

如果它不起作用，请告诉我。
