将变化价格添加到 Woocommerce 中的可变产品下拉项目名称

问题描述

我正在使用此代码获取可变产品选项

I'm using this code to get the variable product options

$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，但都没有正确

I tried a lot of codes to get price next to the name in dropdown menu , but nothing get right

推荐答案

只有当您在变量 product (因此只有一个下拉菜单)中只设置了一个变体的产品属性时，它才会起作用.

如果您的变量产品中有多个下拉菜单，由于变体是不同产品属性值的组合，因此逻辑上将无法正常工作.

If you have more than one dropdowns in your variable product, as the variations are a combination of the different product attributes values, it will not work logically.

因此，以下代码将在唯一产品属性下拉列表中显示产品变体价格:

So the following code will display the product variation price in a unique product attribute dropdown:

// 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;
}

代码位于活动子主题(或活动主题)的 function.php 文件中.经测试有效.

Code goes in function.php file of your active child theme (or active theme). Tested and works.
