php - Woocommerce:获取运输邮政编码以计算运费

Question

我正在开发一种新的运输方式，它根据包裹重量、体积和客户邮政编码计算费率... 我在 calculate_shipping 函数上检索购物车信息没有问题，但是当我尝试从客户那里检索邮政编码时，它似乎返回一个空值。 我如何才能在运行时检索此信息以计算最终成本？

public function calculate_shipping( $package ) { 
    GLOBAL $woocommerce; 
    $items = $woocommerce->cart->get_cart(); 
    $cliente = $woocommerce->customer;  
    $peso = $woocommerce->cart->cart_contents_weight; 
    $customer_postcode = $woocommerce->customer->get_shipping_postcode(); 
}

已解决:

$customer_postcode = get_user_meta( get_current_user_id(), 'shipping_postcode', true );

Answer 1

// add this in your calculate_shipping function
public function calculate_shipping( $package ) {
     //remove the first bracket at the end of $postal_code
     $postal_code = $package[ 'destination' ][ 'postcode' ];
}
