php结合layui前端实现多图上传

前端html代码

<div class="layui-upload">

 <button type="button" class="layui-btn layui-btn-normal" id="testList">请选择图片</button>

 <span class="num_pic"></span>

 <div class="layui-upload-list">

 <table class="layui-table">

 <thead>

 <tr>

 <th>文件名</th>

 <th id="pic">图片预览</th>

 <th>大小</th>

 <th>状态</th>

 <th id="cao">操作</th>

 </tr>

 </thead>

 <tbody id="demoList"></tbody>

 </table>

 </div>

 <button type="button" class="layui-btn" id="testListAction">开始上传</button>

 <span class="num_pic"></span>

</div>
