layui框架实现文件上传及TP3.2.3(thinkPHP)对上传文件进行后台处理操作示例

<div class="layui-form-item" id="upload_file">     <div class="layui-input-block" style="width: 300px;">      <input type="hidden" id="img_url1" name="HeadImageUrl" value=""/>      <div class="layui-upload-drag" id="uploadpic1" lay-verify="uploadpic1">        <div class="layui-col-xs12 layui-col-md12">          <img class="layui-upload-img" id="demo1" >        </div>        <div class="button-hide">          <input type="file" name="banner_file_upload" id="banner_file_upload" class="layui-uplaod-file"  lay-type="file">        </div>      </div>    </div></div>
