我的问题是，当我成功删除一行时，我希望我的页面返回显示之前显示的表格，减去我已经删除的具有完全相同页码的行。我需要解析进出 KRS-Delete.php 的内容

Answer 1

在构建涉及多个步骤的 UI 页面时，我更喜欢将所有步骤放在同一个 PHP 文件中。我从 $foo = @$_GET['foo']; 开始if ($foo) DoFoo(); 查看此调用是否需要执行“foo”步骤(例如执行 DELETE)。在 DoFoo() 之后，我通常会进入主代码，它呈现与原始页面相同(或相似)的 UI 页面。

除了避免您提到的导航问题外，它还允许我在一个文件中包含此 UI 的“所有”内容。通常也有很多通用代码。
