thinkphp和uploadfiy

上传页面 用的是bootstrap

  <div class="col-sm-6">
                                        <div style="width: 200px; height: 110px; float: left;">
                                            <input type="hidden" name="photo" value="" id="data_photo" />
                                            <input id="photo_file" name="photo_file" type="file" multiple="true" value="" />
                                        </div>
                                        <div style="height: 110px; float: left;">
                                            <img id="upload_img" src="" onerror="this.src='__PUBLIC__/Admin/img/no_img.jpg'" style="height: 100px" />
                                        </div>
                                    </div>

　　

$(function(){

            $('#photo_file').uploadify({
                'swf' :'__PUBLIC__/admin/swf/uploadify.swf',  //swf的相对路径
                'uploader': '{:U("Upload/upload")}',　　//后台处理
                'buttonText': '上传头像', //按钮
                'height': 35,  //高度
                'fileTypeExts': '*.gif;*.jpg;*.png',  //上传类型
                'queueSizeLimit': 1, 
                'onUploadSuccess': function(file, data, response) { 

                    $("#upload_img").attr('src', '__PUBLIC__/Uploads/adminimg/' + data);  //预览效果
                    $("#data_photo").val(data);
                }
            });
