Question

我已从2.6.14更新到WC 3.0.1 我的原始代码如下：

add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );

function add_custom_price( $cart_object ) {
    $custom_price = 10; // This will be your custome price  
    foreach ( $cart_object->cart_contents as $key => $value ) {
        $value['data']->price = $custom_price;
    }
}

不再更新购物车或迷你车的价格。

Answer 1

对于最新版本的Woocommerce（3.0.1）中的购物车价格，请尝试在woocommerce中使用set_price（$ price）功能，这将有所帮助。 Source here

add_action( 'woocommerce_before_calculate_totals', 'woocommerce_pj_update_price', 99 );

function woocommerce_pj_update_price() {

    $custom_price = $_COOKIE["donation"]; // This will be your custom price  
    $target_product_id = 413; //Product ID

    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {

        if($cart_item['data']->get_id() == $target_product_id){

            $cart_item['data']->set_price($custom_price);
        }

    }

}

Answer 2

稍作改动：

//OLD:
$value['data']->price = $custom_price;

//NEW:
$value['data']->set_price( $custom_price );

function add_custom_price( $cart_object ) {
    $custom_price = 10; // This will be your custome price  
    foreach ( $cart_object->cart_contents as $key => $value ) {
        $value['data']->set_price( $custom_price );
    }
}

Answer 3

add_action( 'woocommerce_before_calculate_totals', 'add_custom_price', 10, 1);
function add_custom_price( $cart_obj ) {

    //  This is necessary for WC 3.0+
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    foreach ( $cart_obj->get_cart() as $key => $value ) {
        $value['data']->set_price( 40 );
    }
 }

如果我设置$ value ['data'] - ＆gt; set_price（40）工作正常，但是：

 foreach ( $cart_obj->get_cart() as $key => $value ) {
            $price = 50;
            $value['data']->set_price( $price );
 }

Answer 4

好吧，问题在于您直接通过$value['data']->price致电价格。
做到：

$value['data']->get_price()

我认为您的问题将得到解决

更新到WC 3.0.1后，woocommerce_before_calculate_totals钩子停止工作
