我想显示 Woocommerce 产品页面上变体下拉列表中显示的每个产品变体的库存状态(例如，有货/缺货)。我已将相关功能复制到我的主题的 functions.php 文件中，并且可以编辑内容，但我不确定如何为每个变体提取所需的库存状态。

// Updated Woocommerce Product Variation Select 

if ( ! function_exists( 'wc_dropdown_variation_attribute_options' ) ) {

    /**
     * Output a list of variation attributes for use in the cart forms.
     *
     * @param array $args
     * @since 2.4.0
     */

     /*

    function wc_dropdown_variation_attribute_options( $args = array() ) {
        $args = wp_parse_args( apply_filters( 'woocommerce_dropdown_variation_attribute_options_args', $args ), array(
            'options'          => false,
            'attribute'        => false,
            'product'          => false,
            'selected'         => false,
            'name'             => '',
            'id'               => '',
            'class'            => '',
            'show_option_none' => __( 'Choose an option', 'woocommerce' ),
        ) );

        $options               = $args['options'];
        $product               = $args['product'];
        $attribute             = $args['attribute'];
        $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'] : __( 'Choose an option', 'woocommerce' ); // We'll do our best to hide the placeholder, but we'll need to show something when resetting options.

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

        $html = '';
        $html .= '' . esc_html( $show_option_none_text ) . '';

        if ( ! empty( $options ) ) {
            if ( $product && taxonomy_exists( $attribute ) ) {
                // Get terms if this is a taxonomy - ordered. We need the names too.
                $terms = wc_get_product_terms( $product->get_id(), $attribute, array( 'fields' => 'all' ) );



                foreach ( $terms as $term ) {
                    if ( in_array( $term->slug, $options ) ) {
                        $html .= 'slug ) . '" ' . selected( sanitize_title( $args['selected'] ), $term->slug, false ) . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $term->name ) ) . ' ';
                    }
                }
            } else {
                foreach ( $options as $option ) {
                    // This handles lt 2.4.0 bw compatibility where text attributes were not sanitized.
                    $selected = sanitize_title( $args['selected'] ) === $args['selected'] ? selected( $args['selected'], sanitize_title( $option ), false ) : selected( $args['selected'], $option, false );

                    $html .= '' . esc_html( apply_filters( 'woocommerce_variation_option_name', $option ) ) . '  Output Stock Details Here ';
                }
            }
        }

        $html .= '';

        echo apply_filters( 'woocommerce_dropdown_variation_attribute_options_html', $html, $args );
    }
}

我可以提取整个产品的库存水平，但现在是针对每个变体。

如有任何帮助，我们将不胜感激。

2021 年更新(仅适用于具有1 个下拉菜单的可变产品)-感谢@Alex Banks

Anyway this will really work when there is ONLY ONE dropdown select field (so one attribute for the variations).

With multiple attributes (so multiple dropdown select fields) it displays something that can be wrong depending on the variations stock status attributes terms combination.

See the screenshot at the end that shows a wrong display case…

我已经尝试了 Ali_k 的代码，但是当可变产品有多个下拉菜单时，它在我的测试服务器中不工作。

因此，我对 Ali_k 的代码进行了一些更改，以使其在我的测试服务器(使用最新的 WooCommerce 版本) 中正常工作。

要处理延期交货，请参阅:Add backorders stock status to Woocommerce variable product dropdown

代码:

// 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'];
            break;
        }
    }
    return $stock == 1 ? ' - (In Stock)' : ' - (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'] : __( 'Choose an option', '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_stock_status_text( $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;
}

代码位于您的事件子主题(或主题)的 function.php 文件中或任何插件文件中。

在只有一个变体属性的可变产品中进行测试和工作…

使用 Ali_K 的代码，这里是可变产品的错误显示文本示例具有多个选择字段 (因此有多个属性用于变体):
