[PHP] layui实现多图上传，图片自由排序，自由删除

实现效果如下图所示：

实现代码：

css代码

<style>
.layui-upload-img {  90px; height: 90px; margin: 0; }
.pic-more { 100%; left; margin: 10px 0px 0px 0px;}
.pic-more li { 90px; float: left; margin-right: 5px;}
.pic-more li .layui-input { display: initial; }
.pic-more li a { position: absolute; top: 0; display: block; }
.pic-more li a i { font-size: 24px; background-color: #008800; }   
#slide-pc-priview .item_img img{  90px; height: 90px;}
#slide-pc-priview li{position: relative;}
#slide-pc-priview li .operate{ color: #000; display: none;}
#slide-pc-priview li .toleft{ position: absolute;top: 40px; left: 1px; cursor:pointer;}
#slide-pc-priview li .toright{ position: absolute;top: 40px; right: 1px;cursor:pointer;}
#slide-pc-priview li .close{position: absolute;top: 5px; right: 5px;cursor:pointer;}
#slide-pc-priview li:hover .operate{ display: block;}   
</style>

　　

多图上传页面html代码

<div class="layui-form-item" id="pics">
  <div class="layui-form-label">相册图集</div>
  <div class="layui-input-block" style=" 70%;">
    <div class="layui-upload">
      <button type="button" class="layui-btn layui-btn-primary pull-left" id="slide-pc">选择多图</button>
      <div class="pic-more">
        <ul class="pic-more-upload-list" id="slide-pc-priview">
        </ul>
      </div>
    </div>
  </div>
</div>

     done: function(res) {
        layer.close(layer.msg());//关闭上传提示窗口
         if(res.status == 0) {
             return layer.msg(res.message);
         }
         //$('#slide-pc-priview').append('<input type="hidden" name="pc_src[]" value="' + res.filepath + '" />');

     }

});
//点击多图上传的X,删除当前的图片   
$("body").on("click",".close",function(){
    $(this).closest("li").remove();
  });
 //多图上传点击<>左右移动图片
  $("body").on("click",".pic-more ul li .toleft",function(){
    var li_index=$(this).closest("li").index();
