Deep customization through subtopics and code

When the options provided by the customizer do not meet your needs, it is necessary to proceed with more in-depth customization. To ensure that your customizations are not overwritten when the theme is updated, creating a sub-theme is the best practice. A sub-theme inherits all the features of the parent theme, but it allows you to modify the styles and templates safely.

Basic steps for creating a sub-topic

Creating a sub-topic is very simple. First, on your website…/wp-content/themes/Create a new folder under the directory, for example, name it "New Folder".my-theme-childThen create a necessary file within that folder.style.cssThe file header must contain specific information to declare its parent topic. For example:

/*
 Theme Name:   My Parent Theme Child
 Theme URI:    https://example.com/
 Description:  A child theme of My Parent Theme
 Author:       Your Name
 Author URI:   https://yourwebsite.com
 Template:     my-parent-theme
 Version:      1.0.0
*/

Next, create one.functions.phpFile: This file is not intended to overwrite the file with the same name in the parent theme; instead, it is used to supplement or add new features. Typically, you need to queue the style sheets for the sub-templates here. For example:

<?php
add_action( 'wp_enqueue_scripts', 'my_child_theme_enqueue_styles' );
function my_child_theme_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
    wp_enqueue_style( 'child-style',
        get_stylesheet_directory_uri() . '/style.css',
        array('parent-style'),
        wp_get_theme()->get('Version')
    );
}

Once you activate this sub-topic, you will be able to use its features and content.style.cssAdd any customizations as needed.CSSIt will override the styles of the parent theme.

Using hooks and functions to add functionality

Regarding the modifications to the functionality,WordPressThe hook system provides a powerful and secure way to achieve this. For example, if you want to automatically add a copyright notice at the end of an article, you can use it to do so.the_contentFilter hook: Add the following code to the sub-topic.functions.phpChinese:

add_filter( 'the_content', 'my_add_copyright_notice' );

    if ( is_single() ) {
        $content .= '<p class="copyright-notice">© The copyright of this article belongs to this website.</p>';
    }
    return $content;
}

If you need to make more significant changes to the page structure, you can copy a specific template file from the parent theme to the sub-theme directory and modify it there. For example, to change the display of an article page, you can copy the relevant template from the parent theme to the sub-theme directory and make the necessary adjustments.single.phpCopy it to the sub-topic folder, and then edit this copy directly.
