如何加载＆＃39; custom-header.php＆＃39;来自儿童主题

Question

所以我在WordPress中创建了一个子主题，除了custom-header.php之外，一切都正常。我希望使用子主题中的那个，而不是父主题中的那个。我这样做是试图从我的子主题中的functions.php文件中调用它。 我的子主题的自定义header.php文件位于inc文件夹中，但是已经在主目录中使用其余文件进行了尝试。

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functions.php文件中放入任何require_once语句时，整个网站都会空白。

我的问题

如何加载我的子主题的custom-header.php而不是父主题？

此问题中发布的所有代码均来自子主题。

Answer 1

请完成以下步骤，可以帮助您

例如，您的孩子主题是 {父主题名称} -child

第1步：您的子主题 style.css 文件应该是这样的

/* 
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：将您的父主题“inc / custom-header.php”覆盖为子主题“inc / custom-header.php”< / b>

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中定义 “INC /自定义元素”

在您的子主题“inc / custom-header.php”文件中使用了相同的功能。这就是你网站空白的原因。

因此，您应该重命名子主题“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”文件应该是这样的

步骤4：您的孩子主题 fnctions.php 应该是这样的

<?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' );            

 ?>

Answer 2

您尝试使用网址而不是路径来请求文件。 get_template_directory_uri()会将URL返回到父主题文件夹。

您需要get_stylesheet_directory()才能获得子主题的路径。

替换它：

require_once( get_template_directory_uri() . '/inc/custom-header.php' );

使用：

require_once( get_stylesheet_directory() . '/inc/custom-header.php' );

Answer 3

它可以使用 get_header（）功能

来帮助您

您的自定义标题名称应该与此＆＃34; header-name.php＆＃34; 一样，然后在该函数中调用自定义标题名称。

<?php get_header('name'); ?>
