我最近从woocommerce 2.7跳到了3.1，我对woocommerce_before_calculate_totals 钩住下面的功能。
function calculate_embossing_fee( $cart_object ) {
if( !WC()->session->__isset( "reload_checkout" )) {
/* Gift wrap price */
$additionalPrice = 5;
foreach ( $cart_object->cart_contents as $key => $value ) {
if( isset( $value["embossing_fee"] ) ) {
$orgPrice = floatval( $value[\'data\']->price );
$discPrice = $orgPrice + $additionalPrice;
$value[\'data\']->set_price($discPrice);
}
}
}
}
add_action( \'woocommerce_before_calculate_totals\', \'calculate_embossing_fee\', 99 );
有人知道为什么这会抛出一个错误以及我如何解决它吗？
我得到的错误是：确定：
