Woocommerce通过变体ID隐藏支付网关

Question

In Woocommerce, I need to hide some payments gateway depending on type of variation. I tried:

add_filter( 'woocommerce_available_payment_gateways','eikon_regional_payments', 10, 1 );

function eikon_regional_payments( $array_payments ) {

    if( WC()->product->get_variation_attributes() == 'regional' )

        unset($array_payments['woo-mercado-pago-basic']);

    return $array_payments;
}

But it does not works:
