顯示 現貨 WooCommerce 單品簡短描述

Question

我有許多變體的可變產品，其中只有少數項目實際上是有貨的，而大多數其他變體是“可延期交貨”

我希望能夠在每個產品頁面的簡短產品描述中僅顯示庫存商品的快速列表，這樣客戶就不必逐個嘗試所有變體來最終找出哪些變體有貨。

我已經搜索了可以執行此操作的插件或代碼，但沒有找到任何東西。

我找到的最接近的代碼是：

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'; 
            }
        }
    }
}

但它會在 SHOP 頁面上顯示“有貨”可用的變體，我希望它顯示在單個產品的簡短描述中。

如何在單個產品簡短描述中顯示“有貨”可用變體？

要在簡短描述的產品單頁中顯示庫存變化列表，請使用以下命令：

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;
}
