显示Woocommerce订阅中每月的变化价格

我有三种订阅产品,每年,半年和每月。默认情况下,价格在我的商店页面上按每年,每6个月和每月显示。

基于Change product prices via a hook in WooCommerce 3答案代码,我试图显示每月的所有价格,因此要根据订阅条款更改价格显示:

// Utility function to change the prices with a multiplier (number)
function get_price_multiplier($var_product) {
    switch($var_product) {
        case 111:
            // Annual
            return 12;
            break;
        case 222:
            // Semiannual
            return 6;
            break;
        case 333:
            // Month
            return 1;
            break;          
        default:
            return 1;
            break;
    }
}

add_filter('woocommerce_product_variation_get_price', 'custom_price', 99, 2 );
function custom_price( $price, $product ) {
    $var_product = $product->get_id();
    return $price / get_price_multiplier($var_product);
}

这有效,但是当将产品添加到购物车时,价格不是正常价格,而是上述功能的修改后价格。

基于Set programmatically product sale price and cart item prices in Woocommerce 3答案代码,我已经能够解决此问题:

add_action( 'woocommerce_before_calculate_totals', 'set_cart_item_sale_price', 20, 1 );
function set_cart_item_sale_price( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
        return;

    // Iterate through each cart item
    foreach( $cart->get_cart() as $cart_item ) {
        $regular_price = $cart_item['data']->get_regular_price();
        $variation_id = $cart_item['variation_id'];
        $cart_item['data']->set_price( $regular_price * get_price_multiplier($variation_id) );
    }
}

这重置了购物车的价格,尽管其中一个价格降低了一分钱,但它似乎可以正常工作。

这是否令人费解并且容易出问题,或者是实现我所追求的可靠方法:在商店页面上显示每个订阅条款的价格?

1 个答案:

答案 0 :(得分:1)

您做对的方式正确……有2种方法(最后一种是最好的方法):

  

注意:当乘数等于1时,不需要计算和价格变动。

1)第一种选择:与您非常相似的改进的代码版本。

这是我的评论代码:

// Utility function that increase conditionally the variation price with a multiplier (int)
function get_variation_calculated_price( $variation_id, $price, $multiplier = true ) {
    switch( $variation_id ) {
        case 111: // Annual
            $rate = 12;
            break;

        case 222: // Semi-annual
            $rate = 6;
            break;

        default: // Month (and others)
            $rate = 1;
            break;
    }
    // Return calculated price (or false when multiplier is 1, as calculation is not needed)
    return $rate !== 1 ? ( $multiplier ? $price * $rate : $price / $rate ) : false;
}


// Change variations calculated prices
add_filter('woocommerce_product_variation_get_price', 'custom_price', 99, 2 );
function custom_price( $price, $variation ) {
    if( $new_price = get_variation_calculated_price( $variation->get_id(), $price, false ) )
        return $new_price;

    return $price;
}

// Customizing cart item prices
add_action( 'woocommerce_before_calculate_totals', 'set_cart_item_sale_price', 20, 1 );
function set_cart_item_sale_price( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    // Required since Woocommerce version 3.2 for cart items properties changes
    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
        return;

    // Loop  through cart items
    foreach( $cart->get_cart() as $cart_item ) {
        // Only for variations
        if( $cart_item['variation_id'] > 0 ) {
            if( $new_price = get_variation_calculated_price( $cart_item['variation_id'], $cart_item['data']->get_price() ) ) {
                $cart_item['data']->set_price( $new_price );
            }
        }
    }
}

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。


2)第二种选择:更准确,更轻便,限制了产品价格,避免了购物车,结帐和后端的价格变动。

  

注意:您将需要避免在购物车页面中显示交叉销售产品(因为价格不会像在商店页面中一样发生变化)。

因此,代码将更加轻巧,紧凑和高效:

// Utility function that increase conditionally the variation price with a multiplier (int)
function get_variation_calculated_price( $variation_id, $price ) {
    switch( $variation_id ) {
        case 111: // Annual
            $rate = 12;
            break;

        case 939: // Semi-annual
            $rate = 6;
            break;

        default: // Month (and others)
            $rate = 1;
            break;
    }
    // Return calculated price (or false when multiplier is 1, as calculation is not needed)
    return $rate !== 1 ? $price / $rate : false;
}


// Change variations calculated prices
add_filter('woocommerce_product_variation_get_price', 'custom_price', 99, 2 );
function custom_price( $price, $variation ) {
    // Not in cart, checkout and admin
    if( is_cart() || is_checkout() || is_admin() ) 
        return $price;

    if( $new_price = get_variation_calculated_price( $variation->get_id(), $price ) )
        return $new_price;

    return $price;
}

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。
