Question

如果购物车是免费的，我想在Woocommerce结帐中隐藏结算明细，所以我试图在主题functions.php中获得购物车价格，我收到此错误：

 Call to a member function get_cart_total() on a non-object

我尝试使用的代码是：

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );

global $woocommerce;
if ( $woocommerce->cart->get_cart_total() == 0 ) {
    function kia_filter_billing_fields($fields){
        unset( $fields["billing_email"] );
        unset( $fields["billing_last_name"] );
        unset( $fields["billing_first_name"] );
        unset( $fields["billing_country"] );
        unset( $fields["billing_company"] );
        unset( $fields["billing_address_1"] );
        unset( $fields["billing_address_2"] );
        unset( $fields["billing_city"] );
        unset( $fields["billing_state"] );
        unset( $fields["billing_postcode"] );
        unset( $fields["billing_phone"] );
        return $fields;
    }
}

我在互联网的帮助下度过了这里，但我被困住了。如果你能帮助我，我将不胜感激。

您需要将代码包装在函数中，以便仅在执行woocommerce_checkout_process操作时调用它。

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );

function wc_minimum_order_amount()
{
  global $woocommerce;
  if ( $woocommerce->cart->get_cart_total() == 0 ) {
      function kia_filter_billing_fields($fields){
          unset( $fields["billing_email"] );
          unset( $fields["billing_last_name"] );
          unset( $fields["billing_first_name"] );
          unset( $fields["billing_country"] );
          unset( $fields["billing_company"] );
          unset( $fields["billing_address_1"] );
          unset( $fields["billing_address_2"] );
          unset( $fields["billing_city"] );
          unset( $fields["billing_state"] );
          unset( $fields["billing_postcode"] );
          unset( $fields["billing_phone"] );
          return $fields;
      }
  }
}

在主题函数中获取woocommerce cart总数.php
