Question

基于“ How to add variation stock status to Woocommerce product variation dropdown” 答案，
我编写了一些代码来显示变量产品的自定义属性及其在商店中的存在：

// Function that will check the stock status and display the corresponding additional text
function get_stock_status_text($product, $name, $term_slug) {
    foreach($product - > get_available_variations() as $variation) {
            if ($variation['attributes'][$name] == $term_slug)
                    $stock = $variation['is_in_stock'];
    }

    return $stock == 1 ? '' : ' - out of stock';
}

// The hooked function that will add the stock status to the dropdown options elements.
add_filter('woocommerce_dropdown_variation_attribute_options_html', 'show_stock_status_in_dropdown', 10, 2);

function show_stock_status_in_dropdown($html, $args) {
    // Only if there is a unique variation attribute (one dropdown)
    if (sizeof($args['product'] - > get_variation_attributes()) == 1):

            $options = $args['options'];
    $product = $args['product'];
    $attribute = $args['attribute']; // The product attribute taxonomy
    $name = $args['name'] ? $args['name'] : 'attribute_'.sanitize_title($attribute);
    $id = $args['id'] ? $args['id'] : sanitize_title($attribute);
    $class = $args['class'];
    $show_option_none = $args['show_option_none'] ? true : false;
    $show_option_none_text = $args['show_option_none'] ? $args['show_option_none'] : __('Select size', 'woocommerce');

    if (empty($options) && !empty($product) && !empty($attribute)) {
            $attributes = $product - > get_variation_attributes();
            $options = $attributes[$attribute];
    }

    $html = '<select id="'.esc_attr($id).
    '" class="'.esc_attr($class).
    '" name="'.esc_attr($name).
    '" data-attribute_name="attribute_'.esc_attr(sanitize_title($attribute)).
    '" data-show_option_none="'.($show_option_none ? 'yes' : 'no').
    '">';
    $html. = '<option value="">'.esc_html($show_option_none_text).
    '</option>';

    if (!empty($options)) {
            if ($product && taxonomy_exists($attribute)) {
                    $terms = wc_get_product_terms($product - > get_id(), $attribute, array('fields' => 'all'));

                    foreach($terms as $term) {
                            if (in_array($term - > slug, $options)) {
                                    // HERE Added the function to get the text status
                                    $stock_status = get_stock_status_text($product, $name, $term - > slug);
                                    $html. = '<option value="'.esc_attr($term - > slug).
                                    '" '.selected(sanitize_title($args['selected']), $term - > slug, false).
                                    '>'.esc_html(apply_filters('woocommerce_variation_option_name', $term - > name).$stock_status).
                                    '</option>';
                            }
                    }
            } else {
                    foreach($options as $option) {
                            $selected = sanitize_title($args['selected']) === $args['selected'] ? selected($args['selected'], sanitize_title($option), false) : selected($args['selected'], $option, false);
                            // HERE Added the function to get the text status
                            $stock_status = get_the_stock_status($product, $name, $option);
                            $html. = '<option value="'.esc_attr($option).
                            '" '.$selected.
                            '>'.esc_html(apply_filters('woocommerce_variation_option_name', $option).$stock_status).
                            '</option>';
                    }
            }
    }
    $html. = '</select>';

    endif;

    return $html;
}

在一个产品页面上，我显示了相关产品。如何在相关产品中以标签形式显示此属性（在商店中存在）？

例如：

产品名称

价格-$ 25

可用尺寸：L，XL

Answer 1

尝试使用此代码，我迷上了woocommerce_after_shop_loop_item并显示了产品属性。现在，它仅适用于size属性。它显示了大，中，小。如果要显示L，XL，M等，只需编辑size属性。

add_action( 'woocommerce_after_shop_loop_item', 'mamham_woocommerce_after_shop_loop_item', 10);
function mamham_woocommerce_after_shop_loop_item() {
    global $product;

    // Bail if not in the single product page.
    if ( ! is_product() ) return;

    // Prduct attributes which you want to show.
    // Attributes to show in the slug.
    // 'attribute slug' => 'Text shown';
    $show_attributes = array(
        'size' => 'Sizes available:',
    );

    // Get the slugs.
    $show_slugs = array_keys( $show_attributes );

    // Get product type.
    $product_type = $product->get_type();

    if( 'simple' === $product_type ) {  
        $product_attributes = $product->get_attributes();
        foreach( $product_attributes as $key => $product_attribute ) {
            $slug = substr( $key, 3 );
            if ( in_array( $slug, $show_slugs, TRUE ) ) {
                $terms = $product_attribute->get_terms();
                $terms_output = wp_list_pluck( $terms, 'name');
                $terms_output = implode(', ', $terms_output );
                echo esc_html( "${show_attributes[$slug]} ${terms_output}" );
            }
        }

    } elseif ( 'variable' === $product_type ) {
        $product_variations = $product->get_available_variations();     
        foreach ( $product_variations as $product_variation ) {
            if ( $product_variation['is_in_stock'] && isset( $product_variation['attributes']['attribute_pa_size'] )) {
                $terms_output[] = ucwords( $product_variation['attributes']['attribute_pa_size'] );
            }           
        }       
        if ( ! empty( $terms_output) ) {
            $terms_output = implode(', ', $terms_output );
            echo esc_html( "Sizes available: ${terms_output}" );
        }       
    }
}

这是屏幕截图，我已经安装了店面主题和WooCommerce。

在相关产品列表中显示自定义属性“可变产品”
