在WORDPRESS中使用IF语句显示不同的标头

Question

guru's：D

我在header.php文件中使用IF-staments时遇到问题。

我正在使用wordpress平台。下面的代码应通过检查用户当前所在的页面来显示不同样式的标题。

我的问题：当我在任何页面中调用get_header();时，我会从中获取所有代码 header.php文件，似乎功能并不关心我的IF-stament header.php文件。

非常感谢任何帮助。

下面的代码是我的header.php文件。

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>">

<?php
$post_obj = $wp_query->get_queried_object();
var_dump($slug);
?>

<?
if (is_page($slug == "student_info")) {
?>
