问题描述
我想在结帐时根据数量阈值对特定产品打折:
- 当产品> = 10单位时-----每单位优惠2美元
- 当产品> = 20单位时-----每单位折扣3美元
所需的样本输出示例:
- 乘积×10等于$ 730.00 |优惠是$ 20.00 |优惠后总计:$ 710.00
- 乘积×20等于$ 1460.00 |优惠是$ 60.00 |折后总额:$ 1400.00 $ 1,400.00
到目前为止,我有这个功能,但是当我将10个单位的产品添加到购物车中时,会遇到严重错误。
我的代码:
add_action( 'woocommerce_before_calculate_totals','quantity_based_pricing',9999 );
function quantity_based_pricing( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 ) return;
// Define discount rules and thresholds
$threshold1 = 10; // Change price if items > 10
$discount1 = 0.02739726027; // Reduce 73 dollar unit price by 2 dollars
$threshold2 = 20; // Change price if items > 20
$discount2 = 0.04109589041; // Reduce 73 dollar unit price by 3 dollars
//compare
foreach ( $cart->get_cart() as $cart_item_key => $cart_item )
// Get product id
$product_id = $cart_item['product_id'];
if ( $cart_item['quantity'] >= $threshold1 && $cart_item['quantity'] < $threshold2 && $cart_item = '283' ) {
$price = round( $cart_item['data']->get_price() * ( 1 - $discount1 ),2 );
$cart_item['data']->set_price( $price );
} elseif ( $cart_item['quantity'] >= $threshold2 && in_array( $product_id,$specific_product_ids ) ) {
$price = round( $cart_item['data']->get_price() * ( 1 - $discount2 ),2 );
$cart_item['data']->set_price( $price );
}
}
我在做什么错?如何使它正常工作?
解决方法
您的代码中有一些错误。请尝试以下操作:
function quantity_based_pricing_discount( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Define discount rules and thresholds
$threshold1 = 10; // Change price if items > 10
$threshold2 = 20; // Change price if items > 20
$discount_1 = 2; // Reduce unit price by 2 dollars
$discount_2 = 3; // Reduce unit price by 3 dollars
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item ) {
// Targeting specific product id
if( $cart_item['product_id'] == '283' ) {
$price = $cart_item['data']->get_price();
$qty = $cart_item['quantity'];
if ( $qty >= $threshold1 && $qty < $threshold2 ) {
$discount = $discount_1;
} elseif ( $qty >= $threshold2 ) {
$discount = $discount_2;
}
if ( isset($discount) ) {
$cart_item['data']->set_price( round( $price - $discount,2 ) );
}
}
}
}
代码进入活动子主题(或活动主题)的functions.php文件中。经过测试,可以正常工作。
