页面正确加载表格中的结果（从初始页面正确传递的变量/值）;根据设置的'限制'具有正确的记录数;分页正确地将记录划分为页面。
我在代码中需要帮助的两件事：
1）分页应该显示'Previous 1 2 3 ... 6 7 8 Next';但显示'上一页1 2 3 4 5 6 7 8下一步'。代码对我来说似乎很好 - 尝试在线查找各种帖子但没有找到解决此问题的任何内容。
2）页面加载结果后，我点击下一页，它进入下一页但没有显示记录（空白表;但显示所有其他静态项目）。我查了一下，'page'变量被传递到下一页。它也没有出现任何错误。
我对PHP的了解有限，已阅读了几篇帖子但未能解决。
以下是代码 - 如果有人可以提供帮助，我会非常感激。 文件名：display.php 变量从以前的文件传递：index.php
