我正在尝试从函数 $GetTotalPrice
传递购物车的总量( cart_prices_GetPrice()
)发挥作用cart_prices_ApplyPrice()
, 使用 woocommerce_after_calculate_totals
和 woocommerce_before_calculate_totals
钩子(Hook),但我得到一个空值。
//Trying to get cart amount
add_action('woocommerce_after_calculate_totals', 'cart_prices_GetPrice');
function cart_prices_GetPrice() {
//Getting the cart amount
$GetTotalPrice = WC()->cart->get_cart_total();
return $GetTotalPrice;
}
//Applying custom price
add_action('woocommerce_before_calculate_totals', 'cart_prices_ApplyPrice');
function cart_prices_ApplyPrice( $cart_object ) {
//Getting the cart amount from first function
$totalprice = cart_prices_GetPrice(); // doesn't work and returns 0 :(
//price change to cost2
if( $totalprice != 0 && $totalprice >= 2000 ) {
foreach ( $cart_object->get_cart() as $cart_id => $cart_item ) {
// get products id
$product_id = $cart_item['product_id'];
if( $cart_item['product_id'] == $product_id ) {
// price change to cost2
$new_price1 = 0.20;
$cart_item['data']->set_price( $new_price1 );
}
}
}
}
同时,每个功能都可以完美运行。我究竟做错了什么?是否有可能以某种方式链接两个钩子(Hook)数据,以便第一个不返回空值?
更新:
我将无法拒绝钩子(Hook)
woocommerce_before_calculate_totals
,因为我需要为购物车中的每个产品单独 Markdown 。
最佳答案
您不能在 woocommerce_before_calculate_totals
中使用购物车总数当您出于多种原因想要更改购物车商品价格时……
相反,您将在 woocommerce_before_calculate_totals
内获得购物车项目小计钩。在下面的代码中,我使用了包含税费的折扣购物车商品小计:
add_action('woocommerce_before_calculate_totals', 'customize_cart_item_prices');
function customize_cart_item_prices( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Avoiding the hook repetition for price calculations
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
$threshold_amount = 1000; // Min subtotal
$discount_rate = 0.2; // price discount rate (20%)
$cart_items = $cart->get_cart();
// Getting non discounted cart items subtotal
$subtotal_excl_tax = array_sum( wp_list_pluck( $cart_items, 'line_subtotal' ) );
$subtotal_tax = array_sum( wp_list_pluck( $cart_items, 'line_subtotal_tax' ) );
// Getting discounted cart items subtotal
$total_excl_tax = array_sum( wp_list_pluck( $cart_items, 'line_total' ) );
$total_tax = array_sum( wp_list_pluck( $cart_items, 'line_tax' ) );
if( ( $total_excl_tax + $total_tax ) >= $threshold_amount ) {
// Loop through cart items
foreach ( $cart_items as $item ) {
$price = $item['data']->get_price(); // Get price
$item['data']->set_price( $price * ( 1 - $discount_rate ) ); // Set new price
}
}
}
代码位于事件子主题(或事件主题)的 functions.php 文件中。测试和工作。请参阅 Change cart item prices in Woocommerce 3回答代码,查看如何处理 minicart 显示的自定义购物车项目价格。
