ThinkPHP file upload example tutorial

This article mainly introduces ThinkPHP file Upload implementation method, which is a very common technique in ThinkPHP program development. if you need ThinkPHP, refer to ThinkPHP.

File upload is a common feature in many PHP program projects. This article will share a complete example to implement the ThinkPHP file upload function. The specific method is as follows:

I. action:

The FileAction. class. php page code is as follows:

<? Phpclass FileAction extends Action {function index () {$ file = M ('file'); $ list = $ file-> select (); $ this-> assign ('filelist', $ list); $ this-> display ();} function upload () {// submit the file upload address to him, after the upload is complete, a message is returned so that it can be written to the database if (empty ($ _ FILES) {$ this-> error ('upload file required ');} else {$ a = $ this-> up (); if (isset ($ )) {// custom c method for writing data to the database if ($ this-> c ($ a) {$ this-> success ('uploaded successfully ');} else {$ this-> error ('database writing failed') ;}} else {$ this-error ('upload file File exception. contact the system administrator ') ;}} private function c ($ data) {$ file = M ('file'); $ num = '0 '; for ($ I = 0; $ I <count ($ data)-1; $ I ++) {$ data ['filename'] = $ data [$ I] ['savename']; if ($ file-> data ($ data)-> add ()) {$ num ++ ;}}if ($ num = count ($ data)-1) {return true ;}else {return false ;}} private function up () {// call the import ('@. org. uploadFile '); // Upload class UploadFile. class. copy php to the Lib/Org folder $ upload = new UploadFile (); $ upload-> maxSize = '000000'; // The default value is-1. the upload size is not limited. $ upload-> savePath = '. /Public/Upload/'; // It is recommended that you save $ upload-> saveRule = uniqid in a directory at the same level as the master file or in a subdirectory of the same level; // rules for saving uploaded file names $ upload-> uploadReplace = true; // specifies whether to overwrite $ upload-> allowExts = array ('jpg ', 'jpeg ', 'PNG', 'GIF'); // type of the file to be uploaded $ upload-> allowTypes = array ('image/png ', 'image/jpg ', 'image/jpeg ', 'image/GIF'); // detect mime Types $ upload-> thumb = true; // whether to enable image file thumbnails $ upload -> ThumbMaxWidth = '000000'; $ upload-> thumbMaxHeight = '000000'; $ upload-> thumbPrefix ='s _, m _'; // prefix of the thumbnail file $ upload-> thumbRemoveOrigin = 1; // if a thumbnail is generated, whether to delete the original image if ($ upload-> upload ()) {$ info = $ upload-> getUploadFileInfo (); return $ info;} else {$ this-> error ($ upload-> getErrorMsg ()); // used to obtain the uploaded error message }}?>

II. view template:

The template file index.html code is as follows:

I believe the examples described in this article can be used as a reference for ThinkPHP program development.
