在 WooCommerce 单品简短描述中显示库存可用变体

Question

我有很多变化的产品，其中只有少数商品实际有货，而大多数其他变化是“'available on backorder'”

我希望能够在每个产品页面的简短产品描述中仅显示库存商品的快速列表，这样客户就不必逐一尝试所有变体终于知道哪些有货了。

我搜索过可以执行此操作的插件或代码，但没有找到任何东西。

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

    if ( $product->get_type() == 'variable' ) {
        foreach ( $product->get_available_variations() as $key ) {
            $attr_string = array();

            foreach ( $key['attributes'] as $attr_name => $attr_value ) {
                $attr_string[] = $attr_value;
            }

            if ( $key['max_qty'] > 0 ) { 
              echo '<br/>' . implode( ', ', $attr_string ) . ': ' . $key['max_qty'] . ' in stock'; 
            } else { 
              echo '<br/>' . implode(', ', $attr_string ) . ': out of stock'; 
            }
        }
    }
}

但它在 SHOP 页面上显示“有货”可用变体，我希望它显示在单个产品的简短描述中。

如何在单个产品的简短描述中显示“有货”的可用变体？

要在简短描述的产品单页中显示库存变体列表，请使用以下内容：

add_filter( 'woocommerce_short_description', 'display_in_stock_variations_to_short_description' );
function display_in_stock_variations_to_short_description( $excerpt ){
    global $product;

    if ( ! is_product() || empty($product) || ! is_a( $product, 'WC_Product' ) ) 
        return $excerpt;

    if( $product->is_type('variable') ) {
        // Loop through visible children
        foreach( $product->get_children() as $variation_id ) {
            $variation = wc_get_product( $variation_id );

            // Hide out of stock variations if 'Hide out of stock items from the catalog' is checked.
            if ( ! $variation || ! $variation->exists() || ( 'yes' === get_option( 'woocommerce_hide_out_of_stock_items' ) && ! $variation->is_in_stock() ) ) {
                continue;
            }

            // Filter 'woocommerce_hide_invisible_variations' to optionally hide invisible variations (disabled variations and variations with empty price).
            if ( apply_filters( 'woocommerce_hide_invisible_variations', true, $product->get_id(), $variation ) && ! $variation->variation_is_visible() ) {
                continue;
            }

            $max_qty    = 0 < $variation->get_max_purchase_quantity() ? $variation->get_max_purchase_quantity() : $variation->get_stock_quantity();
            $term_names = []; // Initializing

            // Loop through variation attributes for current varation
            foreach ( $variation->get_variation_attributes() as $attribute => $term_slug ) {
                // Set the term name in an array
                $term_names[] = ucfirst( str_replace( ['-', '_'],[' ', ' '], $term_slug ) );
            }

            if ( $max_qty > 0 ) {
                $excerpt .= sprintf( '<br/>%s: %s %s',
                    implode(', ', $term_names),
                    $max_qty,
                    __('in stock', 'woocommerce')
                );
            }
        }
    }
    return $excerpt;
}


// Avoid additional content from product short description to be displayed in variation description
add_filter( 'woocommerce_available_variation', 'filter_wc_available_variation_desscription', 10, 3);
function filter_wc_available_variation_desscription( $data, $product, $variation ) {
    $max_qty    = 0 < $variation->get_max_purchase_quantity() ? $variation->get_max_purchase_quantity() : $variation->get_stock_quantity();
    
    if( $max_qty > 0 )
        $data['variation_description'] = get_post_meta( $variation->get_id(), '_variation_description', true );

    return $data;
}
