Thinkphp5.0分页和跳页

后台查询商品或者会员量需要用到分页展示列表，当页数比较多的时候为了体高用户体验度，需要添加一个跳页也就是手动输入页码数进行快速跳转指定页面。由于手动编写分页比较麻烦，又想使用TP5自带的分页，但是TP5自带的分页类比较简单，所以可以通过修改Bootstrap类自定义显示分页的页码和数量。

由于Bootstrap类是tp自带的类，所以为了我们尽量不要改动底层自带的类，这里拷贝一下Bootstrap类然后重命名为BootstrapDetailed.php，目录结构如图：

代码如下：

然后再config里面配置一下分页类就可以了。

//分页配置
'paginate'               => [
'type'      => 'BootstrapDetailed',
'var_page'  => 'page',
'list_rows' => 15,
],

举个例子：

$good_info =Db::table('goods')->paginate(20);

效果如下：

这样就可以了，用户体验度高，方便。很不错的分页。
