WooCommerce：如何在变体标题（标签）和下拉选择器之间添加自定义文本

Question

我们想在产品变体的 title/label 和下拉选择器之间添加（固定的）自定义文本，如下所示。

我们已经尝试过以下代码

add_filter( 'woocommerce_attribute_label', 'custom_attribute_label', 10, 3 );
function custom_attribute_label( $label, $name, $product ) {
    $taxonomy = 'pa_'.$name;

    if( $taxonomy == 'pa_bodenankertyp' )
        $label .= '<div class="custom-label">' . __('MY custom TEXT', 'woocommerce') . '</div>';

    return $label;
}

从这个post

但它不起作用。

如有任何错误的想法或提示，我们将不胜感激！

我不建议使用此挂钩，因为您会在多个地方更改它——您不希望进行任何更改的地方。我建议覆盖特定的 WooCommerce 模板。为此，转到您的子主题并创建以下文件夹结构：

your-child-theme/woocommerce/single-product/add-to-cart/

现在您需要在其中创建一个名为 variable.php 的 PHP 文件并在其中粘贴以下代码：

<?php
/**
 * Variable product add to cart
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/add-to-cart/variable.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce\Templates
 * @version 3.5.5

defined( 'ABSPATH' ) || exit;

global $product;

$attribute_keys  = array_keys( $attributes );
$variations_json = wp_json_encode( $available_variations );
$variations_attr = function_exists( 'wc_esc_json' ) ? wc_esc_json( $variations_json ) : _wp_specialchars( $variations_json, ENT_QUOTES, 'UTF-8', true );

do_action( 'woocommerce_before_add_to_cart_form' ); ?>

            <tbody>
                <?php foreach ( $attributes as $attribute_name => $options ) : ?>
                    <tr>

                                        'options'   => $options,
                                        'attribute' => $attribute_name,
                                        'product'   => $product,
                                    )
                                );
                                echo end( $attribute_keys ) === $attribute_name ? wp_kses_post( apply_filters( 'woocommerce_reset_variations_link', '<a class="reset_variations" href="#">' . esc_html__( 'Clear', 'woocommerce' ) . '</a>' ) ) : '';
                            ?>
                        </td>
                    </tr>
                <?php endforeach; ?>
            </tbody>
        </table>

        <div class="single_variation_wrap">
            <?php
                /**
                 * Hook: woocommerce_before_single_variation.
                 */
                do_action( 'woocommerce_before_single_variation' );

                /**
                 * Hook: woocommerce_single_variation. Used to output the cart button and placeholder for variation data.
                 *
                 * @since 2.4.0
                 * @hooked woocommerce_single_variation - 10 Empty div for variation data.
                 * @hooked woocommerce_single_variation_add_to_cart_button - 20 Qty and cart button.
                 */
                do_action( 'woocommerce_single_variation' );

                /**
                 * Hook: woocommerce_after_single_variation.
                 */
                do_action( 'woocommerce_after_single_variation' );
            ?>
        </div>
    <?php endif; ?>

    <?php do_action( 'woocommerce_after_variations_form' ); ?>
</form>

<?php
do_action( 'woocommerce_after_add_to_cart_form' );

在此代码中，您将找到 div。如果您需要任何支票，只需将它们放在 div 周围即可。在你的情况下，我会检查变量 $attribute_name.
