根据 WooCommerce 中的用户类型启用不同的产品变体价格

Question

在 Woocommerce 中，我有一个可变产品，其中有一些变体，一些变体有自己的正常价格和促销价。

另外我还有三类用户，价格是分开的：

普通客户，
批发商 1，
批发商 2.

我想当用户：

已登录，
- 顾客：促销价为活动价，但也显示正常价。
- 批发商1和2：自定义价格为有效价格，但也显示正常价格。
未登录，正常价格为有效价格

主要受答案代码的启发，这里是我的代码尝试：

// Add custom field to VARIATIONS option pricing
add_action( 'woocommerce_variation_options_pricing', 'w4dev_add_variation_options_pricing', 20, 3 );
function w4dev_add_variation_options_pricing( $loop, $variation_data, $post_variation )
{
    $value1  = get_post_meta( $post_variation->ID, '_wholesale_price_1', true );
    $value2  = get_post_meta( $post_variation->ID, '_wholesale_price_2', true );

    $symbol = ' (' . get_woocommerce_currency_symbol() . ')';
    $key_1 = '_wholesale_price_1[' . $loop . ']';
    $key_2 = '_wholesale_price_2[' . $loop . ']';

    
    echo '<div class="variable_wholesale-price"><p class="form-row form-row-first">
        <label>' . __( "Big Dealer Price", "woocommerce" ) . $symbol . '</label>
        <input type="text" size="5" name="' . $key_1 .'" value="' . esc_attr( $value1 ) . '" />
    </p></div>';

    echo '<div class="variable_wholesale-price"><p class="form-row form-row-first">
        <label>' . __( "Small Dealer Price", "woocommerce" ) . $symbol . '</label>
        <input type="text" size="5" name="' . $key_2 .'" value="' . esc_attr( $value2 ) . '" />
    </p></div>';
}


// Save "Wholesale Price" custom field to VARIATIONS
add_action( 'woocommerce_save_product_variation', 'w4dev_save_product_variation_wholesale_price', 20, 2 );
function w4dev_save_product_variation_wholesale_price( $variation_id, $i )
{
    if ( isset( $_POST['_wholesale_price_1'][$i] ) ) 
    {
        update_post_meta( $variation_id, '_wholesale_price_1', floatval( $_POST['_wholesale_price_1'][$i] ) );
    }
    
    if ( isset( $_POST['_wholesale_price_2'][$i] ) ) 
    {
        update_post_meta( $variation_id, '_wholesale_price_2', floatval( $_POST['_wholesale_price_2'][$i] ) );
    }
}


// Variable product price range
add_filter('woocommerce_variation_prices_price', 'w4dev_custom_variation_price', 90, 3 );
add_filter('woocommerce_variation_prices_regular_price', 'w4dev_custom_variation_price', 90, 3 );

add_filter('woocommerce_product_variation_get_regular_price', 'w4dev_custom_price', 90, 2 );
add_filter('woocommerce_product_variation_get_price', 'w4dev_custom_price', 90, 2 );;

function w4dev_custom_variation_price( $price, $variation, $product ) 
{
    if (is_user_logged_in()) 
    {
        $level = get_user_meta(get_current_user_id(), 'wholesale_level', true);
        switch ($level) 
        {
            case 1: $key = '_wholesale_price_1'; break;
            case 2: $key = '_wholesale_price_2'; break;
            default:

                if( get_post_meta( $variation->get_id(), '$key', true ) )
                $price = get_post_meta( $variation->get_id(), '$key', true );
        }
    }
    else
    {   
        return $price;
    }

    return get_post_meta($variation->get_id(), $key, true);
 }

这只显示正常价格和促销价，而不是用户特定价格。

Answer 1

您需要将客户促销价设置为您的自定义价格，这意味着在产品中添加一个额外的自定义字段……这也意味着您将不会使用 WooCommerce 促销价并将其保留为空关于您的产品变体。这将允许您显示：

对于未登录的用户：默认的 WooCommerce 正常价格
对于已登录的客户：自定义销售价格（带有常规价格删除线）
对于批发用户：自定义批发价（带有常规价格删除线）

要完成可变价格范围的缓存，因此您需要一些额外的代码才能使其正常工作，而不会影响您的网站性能。

代码：

// Add custom fields to variations option pricing
add_action( 'woocommerce_variation_options_pricing', 'add_variation_wholesale_options_pricing', 20, 3 );
function add_variation_wholesale_options_pricing( $loop, $variation_data, $post_variation )
{
    $value1  = get_post_meta( $post_variation->ID, '_wholesale_price_1', true );
    $value2  = get_post_meta( $post_variation->ID, '_wholesale_price_2', true );
    $value3  = get_post_meta( $post_variation->ID, '_customer_price', true );

    $symbol = ' (' . get_woocommerce_currency_symbol() . ')';

    $key_1 = '_wholesale_price_1[' . $loop . ']';
    $key_2 = '_wholesale_price_2[' . $loop . ']';
    $key_3 = '_customer_price[' . $loop . ']';

    // Customer price (will be the sale price)
    echo '<div class="variable_customer-price"><p class="form-row form-row-first">
        <label>' . __( "Customer Price", "woocommerce" ) . $symbol . '</label>
        <input type="text" size="5" name="' . $key_3 .'" value="' . esc_attr( $valu3 ) . '" />
    </p></div>';

    // Wholesale 1 price
    echo '<div class="variable_wholesale-price"><p class="form-row form-row-first">
        <label>' . __( "Big Dealer Price", "woocommerce" ) . $symbol . '</label>
        <input type="text" size="5" name="' . $key_1 .'" value="' . esc_attr( $value1 ) . '" />
    </p></div>';

    // Wholesale 2 price
    echo '<div class="variable_wholesale-price"><p class="form-row form-row-first">
        <label>' . __( "Small Dealer Price", "woocommerce" ) . $symbol . '</label>
        <input type="text" size="5" name="' . $key_2 .'" value="' . esc_attr( $value2 ) . '" />
    </p></div>';
}


// Save variations wholesale prices custom fields values
add_action( 'woocommerce_save_product_variation', 'save_product_variation_wholesale_price', 20, 2 );
function save_product_variation_wholesale_price( $variation_id, $i )
{
    if ( isset( $_POST['_wholesale_price_1'][$i] ) )
    {
        update_post_meta( $variation_id, '_wholesale_price_1', floatval( $_POST['_wholesale_price_1'][$i] ) );
    }

    if ( isset( $_POST['_wholesale_price_2'][$i] ) )
    {
        update_post_meta( $variation_id, '_wholesale_price_2', floatval( $_POST['_wholesale_price_2'][$i] ) );
    }

    if ( isset( $_POST['_customer_price'][$i] ) )
    {
        update_post_meta( $variation_id, '_customer_price', floatval( $_POST['_customer_price'][$i] ) );
    }
}

// Variable product price ramge
add_filter('woocommerce_variation_prices_price', 'wholesale_variation_price', 900, 2 );
add_filter('woocommerce_variation_prices_sale_price', 'wholesale_variation_price', 900, 2 );

// Product variations (of a variable product)
add_filter('woocommerce_product_variation_get_price', 'wholesale_variation_price', 900, 2 );

function wholesale_variation_price( $price, $object )
{
    if ( is_user_logged_in() ) {
        $level = (int) get_user_meta( get_current_user_id(), 'wholesale_level', true );
        // For Wholesale user levels 1 and 2
        if( in_array($level, [1, 2]) ) {
            $new_price = (float) get_post_meta( $object->get_id(), '_wholesale_price_' . $level, true );
            $price     = empty($new_price) ? $price : $new_price;
        }
        // For customers
        else {
            $new_price = (float) get_post_meta( $object->get_id(), '_customer_price', true );
            $price     = empty($new_price) ? $price : $new_price;
        }
    }
    return $price;
}

// Handling custom variable price range caching
add_filter( 'woocommerce_get_variation_prices_hash', 'wholesale_variation_performances_caching_prices', 99, 1 );
function wholesale_variation_performances_caching_prices( $hash ) {
    if ( is_user_logged_in() ) {
        $level = (int) get_user_meta( get_current_user_id(), 'wholesale_level', true );
        // For Wholesale user levels 1 and 2
        if( in_array($level, [1, 2]) ) {
            $hash[] = 'level_' . $level;
        }
        // For customers
        else {
            $hash[] = 'level_0'; // Set the user level to zero here
        }
    }
    return $hash;
}
