First, ajax was unable to upload files, which misled me for a while. if I couldn't sleep tonight, I followed the instructions to upload a new file without refreshing.

In fact, the principle is very simple

<Pre class = "code"> class upload <br/>{< br/> public $ _ file; <br/> public function _ construct ($ name = null) <br/>{< br/> if (is_null ($ name) |! Isset ($ _ FILES [$ name]) <br/> $ name = key ($ _ FILES); <br/> if (! Isset ($ _ FILES [$ name]) <br/> throw new Exception ("no file upload "); <br/> $ this-> _ file = $ _ FILES [$ name]; <br/> if (! Is_uploaded_file ($ this-> _ file ['tmp _ name']) <br/> throw new Exception ("Exception "); <br/> if ($ this-> _ file ['error']! = 0) <br/> throw new Exception ("error code :". $ this-> _ file ['error']); <br/>}< br/> public function moveTo ($ new_dir) <br/>{< br/> $ real_dir = $ this-> checkDir ($ new_dir ); <br/> return move_uploaded_file ($ this-> _ file ['tmp _ name'], $ real_dir. '/'. $ this-> _ file ['name']); <br/>}< br/> private function checkDir ($ dir) <br/>{< br/> $ real_dir = realpath ($ dir); <br/> if ($ real_dir = false) <br/> throw new limit T Ion ("The specified directory {$ dir} does not exist"); <br/> if (! Is_writable ($ real_dir) <br/> throw new Exception ("the given directory {$ dir} cannot be written"); <br/> return $ real_dir; <br/>}</pre> <pre class = "code" >}</pre> <p> Call example: </p> <pre class = "code"> $ inputName = 'uploadfile'; <br/> // <input type = & ldquo; name value in file "name =" uploadfile "/>. this parameter is optional. <br/> $ upload = new upload ($ inputName ); <br/> $ new_dir = "/www"; // path to which the file is moved <br/> $ upload-> moveTo ($ new_dir ); </pre> <p> </p> <p align = "left"> <p style = "display: none;"> http://www.bkjia.com/PHPjc/1105144.htmlwww.bkjia.comtruehttp://www.bkjia.com/PHPjc/1105144.htmlTechArticle Hide the iframe file without refreshing the new Upload. iframe refreshes the uploaded file. first, ajax cannot upload the file.
