PHP 变量在 Wordpress 头文件和索引文件中不起作用?

我在 header.php 中有以下代码来回显主体的 ID:<body id="<?php echo $body; ?>">它取自 index.php 的变量:$body = "home";

输出结果为:body id=""

有什么解决这个问题的建议吗?

(我制作了 var_dump($body) 并且值为“home”,所以变量正在工作)

header.php:

<?php
/**
* The Header for our theme.
*
* Displays all of the <head> section and everything up till <div id="main">
*
* @package WordPress
* @subpackage Starkers
* @since Starkers 3.0
*/
?><!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<meta charset="<?php bloginfo( 'charset' ); ?>" />
<title><?php
/*
* Print the <title> tag based on what is being viewed.
* We filter the output of wp_title() a bit -- see
* twentyten_filter_wp_title() in functions.php.
*/
wp_title( '|', true, 'right' );

?></title>
<link rel="profile" href="http://gmpg.org/xfn/11" />
<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" />
<link rel="pingback" href="<?php bloginfo( 'pingback_url' ); ?>" />
<?php
/* We add some JavaScript to pages with the comment form
* to support sites with threaded comments (when in use).
*/
if ( is_singular() && get_option( 'thread_comments' ) )
wp_enqueue_script( 'comment-reply' );

/* Always have wp_head() just before the closing </head>
* tag of your theme, or you will break many plugins, which
* generally use this hook to add elements to <head> such
* as styles, scripts, and meta tags.
*/
wp_head();
?>
</head>

<!--<body <?php body_class(); ?>>-->
<body id="<?php echo $body; ?>">
<div id="header">
<div class="container">
<div id="header-top">
<h1>
<a href="<?php echo home_url( '/' ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a>
</h1>
<!--<p><?php bloginfo( 'description' ); ?></p>-->

<div id="access" role="navigation">
<?php /* Allow screen readers / text browsers to skip the navigation menu and get right to the good stuff */ ?>
<!--<a href="#content" title="<?php esc_attr_e( 'Skip to content', 'twentyten' ); ?>"><?php _e( 'Skip to content', 'twentyten' ); ?></a>-->
<?php /* Our navigation menu. If one isn't filled out, wp_nav_menu falls back to wp_page_menu. The menu assiged to the primary position is the one used. If none is assigned, the menu with the lowest ID is used. */ ?>
<?php wp_nav_menu( array( 'container_class' => 'menu-header', 'theme_location' => 'primary' ) ); ?>
</div><!-- #access -->
<ul id="lang">
<li <?php if($lang_file=='lang.en.php') {echo 'class="current"';} ?>><a href="index.php?lang=en">ENGLISH</a></li>
<li <?php if($lang_file=='lang.zh-tw.php') {echo 'class="current"';} ?>><a href="index.php?lang=zh-tw">CHINESE</a></li>
</ul>
</div>
</div><!-- .container -->
</div><!-- #header -->

index.php:

<?php
/**
* The main template file.
*
* This is the most generic template file in a WordPress theme
* and one of the two required files for a theme (the other being style.css).
* It is used to display a page when nothing more specific matches a query.
* E.g., it puts together the home page when no home.php file exists.
* Learn more: http://codex.wordpress.org/Template_Hierarchy
*
* @package WordPress
* @subpackage Starkers
* @since Starkers 3.0
*/
$body = "home";
include_once 'localization.php';
get_header(); ?>
<div id="content">
<div class="container">
<div id="mainbar">
<?php
/* Run the loop to output the posts.
* If you want to overload this in a child theme then include a file
* called loop-index.php and that will be used instead.
*/
get_template_part( 'loop', 'index' );
?>
<p><?php echo l('test'); ?></p>
</div>
<?php get_sidebar(); ?>
</div><!-- .container -->
</div><!-- #main-content -->
<?php get_footer(); ?>

最佳答案

您正在处理变量作用域问题。

由于包含 header.php 是由 get_header() 函数完成的,因此 header.php 文件中的 $body 变量包含在该函数(即它是函数中的局部变量)。

您需要在 header.php 文件中将该变量声明为全局变量。在对变量做任何其他事情之前,将此行添加到 header.php:

global $body;

我相信这应该有助于实现您正在寻找的行为。
