1、将上传和缩略图处理扩展放在TP核心中，直接覆盖压缩包中的ThinkPHP即可
2、下载jquery.uploadify插件 即文件包中的Public/uploadimg/js/uploadify-v3.1/
3、在上传页面模板引入js和css<link> <br> <script></script>当然也必须引入：jquery库文件
4、在上传页面模板<script><br /> $(function() {<br /> $(&#039;#file_upload&#039;).uploadify({<br /> &#039;swf&#039; : &#039;__PUBLIC__/uploadimg/js/uploadify-v3.1/uploadify.swf&#039;,<br /> &#039;uploader&#039; : &#039;{:U("Student/uploadify")}&#039;,<br /> &#039;buttonText&#039; : &#039;上传头像&#039;,<br /> &#039;onUploadSuccess&#039; : function(file, data, response) {<br /> $(&#039;#image&#039;).attr(&#039;src&#039;,&#039;/Uploads/images/130_&#039;+data);<br /> $(&#039;#pic&#039;).val(data);<br /> },<br /> });<br /> });<br /> </script>5、上传表单：<div> <br> <label>照片：</label><br> <img alt="ThinkPHP图片上传实例" ><br> <input><br> <input><br> </div>6、上传函数：public function uploadify(){<br>     if (!empty($_FILES)) {<br>         import("ORG.NET.UploadFile");<br>         $upload = new UploadFile();<br>         $upload->maxSize = 2048000;<br>         $upload->allowExts = array('jpg','jpeg','gif','png');<br>         $upload->savePath = "./Uploads/images/";<br>         $upload->thumb = true; //设置缩略图<br>         $upload->imageClassPath = "ORG.Util.Image";<br>         $upload->thumbPrefix = "130_,75_"; //生成多张缩略图<br>         $upload->thumbMaxWidth = "130,75";<br>         $upload->thumbMaxHeight = "130,75";<br>         $upload->saveRule = uniqid; //上传规则<br>         $upload->thumbRemoveOrigin = true; //删除原图<br>         if(!$upload->upload()){<br>             $this->error($upload->getErrorMsg());//获取失败信息<br>         } else {<br>             $info = $upload->getUploadFileInfo();//获取成功信息<br>         }<br>         echo $info[0]['savename'];    //返回文件名给JS作回调用<br>     }<br>  }
