我有一个页面principal.php和main.php。当我单击主要部分时，它会在新选项卡中打开主体表单。我不想要它。我想在主要部分显示表格。我怎么能这样做？

<a href="http://www.stackoverflow.com" target="_self">Open it on same page</a>
使用此代码定位同一页面上的超链接。希望这有帮助。

这可能是浏览器问题......
但只是...... ...
<a href="principal.php" target="_self">Principal</a>
只需添加target="_self"。

据我所知，您希望在每个页面上显示导航栏。
解决方案是在head标签中添加样式代码，并在main.php中添加样式中的导航栏列表
您的代码可能如下所示......
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST'){
switch ($_POST['program']){
case 'BSc Computer Science':
include 'csreadprog.php';
break;
case 'BSc Psychology':
include 'psyreadprog.php';
break;
case 'BA Business Administration':
include 'baedreadprog.php';
break;
}
switch ($_POST['services']){
case 'Library':
include 'libraryread.php';
break;
case 'IT Services and Facilities':
include'itserviceread.php';
break;
