英文:
Fatal error: Uncaught Error: Call to undefined function get_header()
问题
我正在处理一个WordPress网站，并遇到了一个关键错误：我已经创建了一个header.php文件，并尝试使用get_header()函数将页眉导入到我的所有页面中。在我的index.php页面中，它工作得很完美，但在我的所有其他页面中，我收到一个错误消息，其中说“致命错误：未捕获的错误：调用未定义的函数get_header()”。出于实验目的，我的index.php页面中的代码与我的所有其他.php页面中的代码相同。我做错了什么？以下是我的一个页面“feedback.php”的代码：
<!DOCTYPE html>
<html>
<head>
<!-- 从header.php导入页眉 -->
<?php get_header() ?>
<title>首页</title>
<link href="https://fonts.googleapis.com/css2?family=Notable&display=swap" rel="stylesheet">
</head>
<body>
<h2>你好，世界</h2>
</body>
</html>
英文:
I am working on a WordPress website and have come across a critical error:I have created a header.php file and tried using the get_header() function to import the header into all of my pages. In my index.php page it works perfectly, but in all of my other pages, I get an error message saying “Fatal error: Uncaught Error: Call to undefined function get_header()”. For experimental purposes, the code in my index.php page is the same as in all of my other .php pages. What am I doing wrong? Here Is the code for one of my pages “feedback.php”:
<!DOCTYPE html>
<html>
<head>
<!-- Import Header from header.php -->
<?php get_header() ?>
<title> Home </title>
<link href="https://fonts.googleapis.com/css2?family=Notable&display=swap" rel="stylesheet">
</head>
<body>
<h2> Hello World </h2>
</body>
</html>

以下是翻译好的部分：
"It sounds like feedback.php is being accessed directly, which doesn't load WordPress. This is why get_header() is undefined."
根据听起来的情况，feedback.php 正在直接访问，这不会加载 WordPress。这就是为什么 get_header() 未定义。
"Depending on the purpose of feedback.php, you may want to use it as a page template (most common), or load WordPress on top of it."
根据 feedback.php 的用途，您可能希望将其用作页面模板（最常见），或在其之上加载 WordPress。
"For using as a page template (most use-cases, and likely yours), read this official WordPress Developer Resource article: https://developer.wordpress.org/themes/template-files-section/page-template-files/."
如果要用作页面模板（大多数用例，可能是您的情况），请阅读此官方 WordPress 开发者资源文章：https://developer.wordpress.org/themes/template-files-section/page-template-files/。
"If you do want to load WordPress on top of the file (uncommon), then you'll need to include the wp-load.php file (root of WordPress install) at the top of the file."
如果您确实想要在文件顶部加载 WordPress（不常见），那么您需要在文件顶部包含 wp-load.php 文件（WordPress 安装的根目录）。
