2个Codeigniter文件批量上传控制器写法例子

例子一：

/** * 多文件上传 ** @author Dream <dream@shanjing-inc.com> */public function multiple_uploads（） {//载入所需类库$this->load->library（"upload"）;//配置上传参数$upload_config = array（"upload_path"=> "","allowed_types" => "jpg|png|gif","max_size" => "500","max_width" => "1024","max_height"=> "768",）;$this->upload->initialize（$upload_config）;//循环处理上传文件foreach （$_FILES as $key => $value） {if （！empty（$key["name"]）） {if （$this->upload->do_upload（$key）） {//上传成功print_r（$this->upload->data（））;} else {//上传失败echo $this->upload->display_errors（）;}}}}

例子二：

function upload（） {$config["upload_path"] = "./uploads/"; /*这里的uploads是相对于index.php的,也就是入口文件,这个千万不要弄错哦！否则就会报错"The upload path does not appear to be valid."; */$config["allowed_types"] = "gif|jpg|png";/*我试着去上传其它类型的文件,这里一定要注意顺序！ A problem was encountered while attempting to move the uploaded file to the final destination.这个错误一般是上传文件的文件名不能是中文名,这个很郁闷！还未解决,大家可以用其它方法,重新改一下文件名就可以解决了！ $config["allowed_types"] = "zip|gz|png|gif|jpg";（正确）$config["allowed_types"] = "png|gif|jpg|zip|gz";（错误）*/$config["max_size"] = "1024";$config["max_width"] = "1024";$config["max_height"] = "768";$config["file_name"] = time（）; //文件名不使用原始名$this->load->library（"upload", $config）;if（！$this->upload->do_upload（）） {echo $this->upload->display_errors（）;}else{ $data["upload_data"]=$this->upload->data（）; //文件的一些信息 $img=$data["upload_data"]["file_name"]; //取得文件名 echo $img."<br>"; foreach（$data["upload_data"] as $item => $value）{ echo $item.":".$value."<br>";}}}
