本文实例讲述了ThinkPHP结合AjaxFileUploader实现无刷新文件上传的方法。分享给大家供大家参考。具体实现方法分析如下：
首先，AjaxFileUploader插件是一个基于jquery的插件，我们可以使用AjaxFileUploader插件来实现文件异步上传功能了，使用这款插件上传文件不要担心兼容性的问题，它的兼容性可以说兼容所有主流浏览器，下面来给大家介绍一个AjaxFileUploader+thinkphp实现文件上传的实例。
ThinkPHP框架下用AjaxFileUploader插件实现ajax文件上传，支持多种文件格式，页面无刷新上传。
在Lib/Action/目录下创建upAction.class.php文件，代码如下：
复制代码 代码如下:
<?php class upAction extends BaseAction{ public function index(){ $this->display(); } /* *@文件上传 *@author FineYi *@date 2013-01-23 */ public function upLoadFile(){ $error = ""; $msg = ""; $fileElementName = 'fileToUpload'; if(!empty($_FILES[$fileElementName]['error'])){ switch($_FILES[$fileElementName]['error']){ case '1': $error = 'The uploaded file exceeds the upload_max_filesize directive in php.ini'; break; case '2': $error = 'The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form'; break; case '3': $error = 'The uploaded file was only partially uploaded'; break; case '4': $error = 'No file was uploaded.'; break; case '6': $error = 'Missing a temporary folder'; break; case '7': $error = 'Failed to write file to disk'; break; case '8': $error = 'File upload stopped by extension'; break; case '999': default: $error = 'No error code avaiable'; } }elseif(empty($_FILES['fileToUpload']['tmp_name']) || $_FILES['fileToUpload']['tmp_name'] == 'none'){ $error = 'No file was uploaded..'; }else{ $re = $this->up(); if(!$re){ $error = 'Up file fail'; } $msg = $re['savename']; //文件名 $path = '/upload/bizcoop/'.$msg; //文件路径 $size = $re['size']; //文件大小 } echo json_encode(array('error'=>$error,'msg'=>$msg,'path'=>$path,'size'=>$size));exit; } private function up(){ import('@.Org.UploadFile');//将上传类UploadFile.class.php拷到Lib/Org文件夹下 $upload=new UploadFile(); $upload->maxSize='-1';//默认为-1，不限制上传大小 $upload->savePath= ICTSPACE_DIST_ROOT_PATH.'/www/upload/bizcoop/';//保存路径 $upload->saveRule=uniqid;//上传文件的文件名保存规则 $upload->uploadReplace=true;//如果存在同名文件是否进行覆盖 $upload->allowExts=array('jpg','jpeg','png','gif');//准许上传的文件类型 if($upload->upload()){ $info=$upload->getUploadFileInfo(); return $info[0]; }else{ return false; exit; } } } ?>
在/Tpl/default/Up/目录下创建index.tpl文件，代码如下：
复制代码 代码如下:
<div id="content"> <h1>Ajax File Upload Demo</h1> <img id="loading" style="display: none;" alt="" src="__APP____PUBLIC__/style/img/loading.gif" /> <form action="" enctype="multipart/form-data" method="POST" name="form"> <table class="tableForm" cellspacing="0" cellpadding="0"> <thead> <tr> <th></th> </tr> </thead> <tbody> <tr> <td><input class="input" id="fileToUpload" type="file" name="fileToUpload" size="45" /></td> </tr> <tr> <td><button class="button" id="buttonUpload" onclick="return ajaxFileUpload();">Upload</button></td> </tr> </tbody> <tbody> <tr> <td><span>已上传的附件:</span></td> </tr> </tbody> <tfoot></tfoot> </table> </form></div>
在/Lib/Org/目录下放入ThinkPHP文件上传类就可以了，有一些插件我们需要到官方下载。
希望本文所述对大家的PHP程序设计有所帮助。
