将变化价格添加到 Woocommerce 中的可变产品下拉项名称

Question

我正在使用此代码获取可变产品选项

$terms = wc_get_product_terms( $bundle_product_id, $name, array( 'fields' => 'all' ) );
foreach ( $terms as $term ) {
    if ( !in_array( $term->slug, $options ) ) {
        continue;
    }
    echo '<option value="' . esc_attr( $term->slug ) . '" ' . selected( sanitize_title( $selected_value ), sanitize_title( $term->slug ), false ) . '>' . apply_filters( 'woocommerce_variation_option_name', $term->name )  . '</option>';
}

我尝试了很多代码来获取下拉菜单中名称旁边的价格，但没有任何结果

Answer 1

It will only work if you have just one product attribute for variations set in the variable product (so only one dropdown).

如果您的可变产品中有多个下拉菜单，因为变体是不同产品属性值的组合，它在逻辑上将不起作用。

因此，以下代码将在唯一的产品属性下拉列表中显示产品变体价格：

// Utility function to get the price of a variation from it's attribute value
function get_the_variation_price_html( $product, $name, $term_slug ){
    foreach ( $product->get_available_variations() as $variation ){
        if($variation['attributes'][$name] == $term_slug ){
            return strip_tags( $variation['price_html'] );
        }
    }
}

// Add the price  to the dropdown options items.
add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'show_price_in_attribute_dropdown', 10, 2);
function show_price_in_attribute_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'];
    $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 ) ) {
                    // Get and inserting the price
                    $price_html = get_the_variation_price_html( $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 ) . ' ::: ' . $price_html ) . '</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 );
                // Get and inserting the price
                $price_html = get_the_variation_price_html( $product, $name, $term->slug );
                $html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $option ) . ' ::: ' . $price_html ) . '</option>';
            }
        }
    }
    $html .= '</select>';

    endif;

    return $html;
}

代码进入您的活动子主题（或活动主题）的 function.php 文件。已测试并有效。

这是我使用 WooCommerce 4.7.0 的简化解决方案。因为我们知道每个变体只有一个属性，所以我们可以只获取第一个值来显示每个变体的正确价格。

/**
 * Display price in variation options dropdown for products that have only one attribute.
 *
 * @param  string $term Existing option term value.
 * @return string $term Existing option term value or updated term value with price.
 */
function display_price_in_variation_options( $term ) {
    $product = wc_get_product();
    $id      = $product->get_id();
    if ( empty( $term ) || empty( $id ) ) {
        return $term;
    }
    if ( $product->is_type( 'variable' ) ) {
        $product_variations = $product->get_available_variations();
    } else {
        return $term;
    }
    foreach ( $product_variations as $variation ) {
        if ( count( $variation['attributes'] ) > 1 ) {
            return $term;
        }
        $attribute = array_values( $variation['attributes'] )[0];
        if ( $attribute === $term ) {
            $term .= ' (' . wp_strip_all_tags( wc_price( $variation['display_price'] ) ) . ')';
        }
    }
    return $term;
}
add_filter( 'woocommerce_variation_option_name', 'display_price_in_variation_options' );
