WordPress自定义标题-错误

我有一个快速的问题。我正在努力使Twentyseventeen主题成为子主题, 并且试图覆盖custom_header代码, 但出现以下错误:

PHP Fatal error:  Cannot redeclare twentyseventeen_custom_header_setup() (previously declared in /Applications/MAMP/htdocs/wordpress/wp-content/themes/twentyseventeen/inc/custom-header.php:36) in /Applications/MAMP/htdocs/wordpress/wp-content/themes/twentyseventeen/inc/custom-header.php on line 52

我尝试重命名该函数, 因此不会重新声明它, 但不能解决问题。到目前为止, 我还没有真正在主题中添加任何其他代码。我还模仿了目录结构, 使其与父主题相同:

资产functions.php inc custom_header.php index.php …

这是我到目前为止拥有的文件:

Functions.php

<?php

函数二十十七岁儿童_enqueue_styles(){$ parent_style =’parent-style’;

    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 )
    );
}
add_action( 'wp_enqueue_scripts', 'twentyseventeenchild_enqueue_styles' );

/**

*/
require get_parent_theme_file_path( '/inc/custom-header.php' );
?>

custom_header.php

add_theme_support( 'custom-header', apply_filters( 'twentyseventeen_custom_header_args', array(
    'default-image'      => get_parent_theme_file_uri( '/assets/images/header.jpg' ), 'width'              => 2000, 'height'             => 1200, 'flex-height'        => true, 'video'              => true, 'wp-head-callback'   => 'twentyseventeen_header_style', ) ) );

register_default_headers( array(
    'default-image' => array(
        'url'           => '%s/assets/images/header.jpg', 'thumbnail_url' => '%s/assets/images/header.jpg', 'description'   => __( 'Default Header Image', 'twentyseventeen' ), ), ) );
}
add_action( 'after_setup_theme', 'twentyseventeen_custom_header_setup' );

在我发布问题之后。我要做的就是将这段代码添加到我的functions.php中

$custom_header_args = array(
    'default-image' => get_theme_file_uri( '/assets/images/header.jpg' ), 'width' => 2000, 'height' => 1200, 'flex-height' => true, 'video' => true, );
add_theme_support('custom-header', $custom_header_args);
