将变化价格添加到Woocommerce中的可变产品下拉菜单项名称中 [英] Add the variation price to variable product dropdown item names in Woocommerce

问题描述

我正在使用此代码来获取可变的产品选项

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>';
}

我尝试了很多代码以在下拉菜单中的名称旁边获取价格，但没有得到正确的答案

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

推荐答案

仅当您在变量产品中仅设置了一个用于变体的产品属性(因此，仅一个下拉列表)时，此方法才有效.

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

如果可变产品中的下拉菜单不止一个，则由于变体是不同产品属性值的组合，因此从逻辑上讲是无效的.

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，以下代码将在唯一的产品属性下拉列表中显示产品变动价格:

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;
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，可以正常工作.

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