页面正确加载，结果显示在表格中（变量/值从初始页面正确传递）；根据设置的“限制”具有正确的记录数；分页正确地将记录分成页面。
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'；而是显示“上一个 1 2 3 4 5 6 7 8 下一个”。该代码对我来说似乎很好 - 尝试在网上查找各种帖子，但没有找到任何解决此问题的方法。
2）页面加载结果后，我点击下一页，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）。我检查了'page'变量并传递到下一页。它也不会带来任何错误。
我对PHP的了解有限，已经阅读了几篇文章但无法解决。
以下是代码 - 如果有人可以提供帮助，我将不胜感激。文件名：display.php 变量是从上一个文件传递过来的：index.php
