首先ajax不能上传文件,这误导了我有段时间,今晚睡不着就照着说明做了个无刷新上传文件 其实原理很简单
复制代码 代码如下:
class upload { public $_file; public function __construct( $name =null) { if(is_null($name) || !isset($_FILES[$name])) $name = key($_FILES); if(!isset($_FILES[$name])) throw new Exception("并没有文件上传"); $this->_file = $_FILES[$name]; if(!is_uploaded_file($this->_file['tmp_name'])) throw new Exception("异常情况"); if($this->_file['error'] !== 0) throw new Exception("错误代码:".$this->_file['error']); } public function moveTo( $new_dir) { $real_dir = $this->checkDir($new_dir); return move_uploaded_file($this->_file['tmp_name'], $real_dir.'//m.sbmmt.com/m/'.$this->_file['name']); } private function checkDir($dir) { $real_dir = realpath($dir); if($real_dir === false) throw new Exception("给定目录{$dir}不存在"); if(!is_writable($real_dir)) throw new Exception("给定目录{$dir}不可写"); return $real_dir; }}
$inputName = 'uploadfile'; // 即 中的name值,不填也行 $upload = new upload($inputName); $new_dir = "/www"; // 将文件移动到的路径 $upload->moveTo($new_dir);
