Question

我购买了Porto Wordpress主题，并创建并激活了子主题。

在子主题中，我放置了一个functions.php文件，以使Woocommerce电话计费字段为可选。

没有结束标记？>可能会导致任何问题。

//make billing fields not required in checkout
add_filter( 'woocommerce_billing_fields', 'wc_npr_filter_phone', 10, 1 );
function wc_npr_filter_phone( $address_fields ) {
$address_fields['billing_phone']['required'] = false;
    return $address_fields;
}

我也放了exit（）;在文件中查看会发生什么，但是什么也没发生。

如何确保完全调用functions.php文件。

全功能。php内容

（某些代码片段可能已经过时，但是它们都不起作用，这很奇怪）。

    add_action( 'wp_enqueue_scripts', 'porto_child_css', 1001 );

    // Load CSS
    function porto_child_css() {
        // porto child theme styles
        wp_deregister_style( 'styles-child' );
        wp_register_style( 'styles-child', esc_url( get_stylesheet_directory_uri() ) . '/style.css' );
        wp_enqueue_style( 'styles-child' );
    }


    // Pre-populate Woocommerce checkout fields
    add_filter('woocommerce_checkout_get_value', function($input, $key ) {

        global $current_user;

        switch ($key) :
            case 'billing_first_name':
            case 'shipping_first_name':
                return "HEEEY".$current_user->first_name;
            break;

            case 'billing_last_name':
            case 'shipping_last_name':
                return $current_user->last_name;
            break;

            case 'billing_email':
                return $current_user->user_email;
            break;

            case 'billing_phone':
                return $current_user->phone;
            break;

        endswitch;

    }, 10, 2);




    // Remove some fields from Woocommerce

    add_filter( 'woocommerce_checkout_fields' , 'custom_remove_woo_checkout_fields' );

    function custom_remove_woo_checkout_fields( $fields ) {

Answer 1

只要您的子主题处于活动状态，就应调用它（转到外观>主题，并确保您的子主题处于活动状态）。您无需在functions.php末尾使用结束标记即可使该文件正常工作。但是，进行测试的一种好方法是调用位于子主题文件夹中的style.css文件。在您的functions.php顶部，您应该能够看到wp_enqueue_style。

还尝试通过使用get_stylesheet_directory_uri（）使子主题style.css入队（Parent style.css使用get_template_directory_uri）。

它应该看起来像这样：

// enqueue styles for child theme
function example_enqueue_styles() {

    // enqueue parent styles
    wp_enqueue_style('parent-theme', get_template_directory_uri() .'/style.css');

    // enqueue child styles
    wp_enqueue_style('child-theme', get_stylesheet_directory_uri() .'/style.css', array('parent-theme'));

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

现在重新加载您的站点->检查站点并选择“网络选项卡”。从这里您可以看到站点上加载的所有文件。尝试找到子主题style.css文件。如果您在“网络”标签中看到该文件，则表示该文件正在被调用。

由于它是高级主题，因此仅应从主题支持团队获得支持和“正确的解决方案”。但是，您可以尝试增加过滤器挂钩的priority。
