srcmini因此, 我在WordPress中创建了一个子主题, 除了custom-header.php之外, 其他所有功能均应正常工作。我希望在子主题中使用一个, 而不在父主题中使用。我这样做是通过尝试从我的子主题中的functions.php文件中调用它来进行的。我在inc文件夹中有我的子主题的custom-header.php文件, 但是已经在主目录中尝试了其余文件。
我的代码(functions.php)
<?php
/**
* Enqueues child theme stylesheet, loading first the parent theme stylesheet.
*/
function nisarg_custom_enqueue_child_theme_styles() {
wp_enqueue_style( 'parent-theme-css', get_template_directory_uri() . '/style.css' );
}
add_action( 'wp_enqueue_scripts', 'nisarg_custom_enqueue_child_theme_styles', 11 );
/* Problem Code Below */
require_once( get_template_directory_uri() . '/inc/custom-header.php' );
问题
问题是这一行：require_once(get_stylesheet_directory()。’/inc/custom-header.php’);每当我在我的functions.php文件中放置任何require_once语句时, 整个网站都会空白。
我的问题
如何加载子主题的custom-header.php而不是父主题的？

此问题中发布的所有代码均来自子主题。
#1
你正在尝试要求使用URL而不是路径的文件。 get_template_directory_uri()将URL返回到父主题文件夹。
你需要get_stylesheet_directory()才能获得子主题的路径。
替换为：
require_once( get_template_directory_uri() . '/inc/custom-header.php' );
带有：
require_once( get_stylesheet_directory() . '/inc/custom-header.php' );
#2
请按照以下步骤操作, 可能对你有帮助
例如, 你的子主题为{父主题名称} -child
步骤1：你的子主题style.css文件应如下所示
/*
Theme Name: {Parent theme name} Child Theme
Theme URI: http://www.example.com/
Description: Theme by Site <a href=\"http://www.example.com//\">http://childthemegenerator.com/</a>
Author: some XYZ
Author URI: http://childthemegenerator.com/
Template: {Parent theme name}
Version: 1.0.0
Text Domain: {Parent theme name}-child
-------------------------------------------------------------- */
/* =Theme customization starts here
------------------------------------------------------- */
步骤2：将父主题” inc / custom-header.php”覆盖为子主题” inc / custom-header.php”
步骤3：编辑每个函数的子主题” inc / custom-header.php”文件, 因为这些函数已在父主题” inc / custom-header.php”中定义。
你的子主题” inc / custom-header.php”文件中使用的功能相同。这就是你获取网站空白的原因。
因此, 你应该重命名子主题” inc / custom-header.php”文件的每个功能并保存。我已经在子主题” inc / custom-header.php”文件中重命名了每个函数。
子主题” inc / custom-header.php”文件应如下所示

步骤4：你的孩子主题fnctions.php应该像这样
<?php
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
require_once( get_stylesheet_directory() . '/inc/custom-header.php' );
?>
#3
通过使用get_header()函数可以为你提供帮助
你的自定义标头名称应类似于” header-name.php”, 然后在该函数中调用自定义标头名称。
<?php get_header('name'); ?>
