服务器不接受文件上传中的视频文件

Question

以下是使用 codeigniter 构建的文件上传功能。这段代码在 locahost 上运行良好，但是当我上传到服务器时，没有任何效果。

文件夹未创建，数据未插入数据库。

            $this->load->library('upload', $config);    

            if ( ! $this->upload->do_upload())
            {

                     }

                            }   


                            copy($upload_config['upload_path'].'/'.$this->config->item('tmp_dir').'/'.$name, $upload_config['upload_path'].'/'.$this->config->item('audio_dir').'/'.$name);
                            // rename($upload_config['upload_path'].'/'.$this->config->item('audio_dir').'/'.$name, $upload_config['upload_path'].'/'.$this->config->item('audio_dir').$name);
                            unlink($upload_config['upload_path'].'/'.$this->config->item('tmp_dir').'/'.$name);

                    if ( $this->upload_model->insert($data) )
                    {

                        $this->load->view('upload_success');
                    }

                    else
                    {

                        redirect(current_url());

                    }


            }


        }

            $this->load->view('upload',$data);


    }
}

现在没有任何效果。我该如何解决这个问题？

更新： 此外，当我尝试上传文件（在本例中为 .mp4 视频）时，我收到错误消息“不允许您尝试上传的文件类型。”，即使我已将其设置为允许的类型。

更新 2：

我一直在尝试上传视频 (.mp4)。我确实将其设置为允许的类型。我试过上传pdf和图片，都上传成功了。

为什么服务器没有上传视频文件？我该如何解决这个问题？

Answer 1

这是你的文档根路径，而不是你必须像这样在 constants.php 中定义的基本 url

define('UPLOAD_PATH',   $_SERVER['DOCUMENT_ROOT'].'/yoururl/assets/uploads/');

当 echo 使用类似的东西时

UPLOAD_PATH.yourimg
