分页尝试转到第 2 页时不显示结果（按名称和日期过滤结果）

技术标签:
【中文标题】分页尝试转到第 2 页时不显示结果（按名称和日期过滤结果）【英文标题】：pagination Show no result when try go to page 2 (Result Filter By Name And Date) 【发布时间】：2019-07-21 16:40:46 【问题描述】：当我尝试转到第 2 页时，我得到了没有结果的空白页
因为第一个条件if ($_SERVER['REQUEST_METHOD'] == 'POST')
在这种情况下，它必须选择名称和日期从和日期到并提交以显示结果，所以当我们转到第 2 页及以后，这个条件$_SERVER['REQUEST_METHOD'] == 'POST' 不是 TRUE 对吗？
任何解决我仍在考虑的想法，但我没有找到，我的头会爆炸：D
我花了 3 天的时间试图解决它:( 我想使用 Stacoverflow 中出现的所有方法，但没有人修复它
这是我的代码和我的帮助数据库
