WooCommerce 'if ( is_cart() )' in functions.php not working?

我在functions.php中添加了下面的代码，这样我就可以更改WooCommerce标准的"添加到购物车通知"。

通知确实发生了变化，但if ( is_cart() )似乎不起作用。它在购物车页面上输出FALSE。

我一定监督了什么。。？

add_filter ( 'wc_add_to_cart_message', 'yw_add_to_cart_message', 10, 2 );
function yw_add_to_cart_message($message, $product_id = null) {
    $titles[] = get_the_title( $product_id );
    $titles = array_filter( $titles );
    if ( is_cart() ) {
        $cart_link  = '<div class="uk-width-medium-1-5 uk-text-right"><a href="' . WC_Cart::get_checkout_url() . '"><i class="uk-icon-check-square-o"></i> ' . __( 'Checkout', 'woocommerce' ) . '</a></div>';
    } else {
        $cart_link  = '<div class="uk-width-medium-1-5 uk-text-right"><a href="' . WC_Cart::get_cart_url() . '"><i class="uk-icon-shopping-cart"></i> ' . __( 'View Cart', 'woocommerce' ) . '</a></div>';
    }
    $added_text = '<div class="uk-grid uk-grid-collapse" data-uk-grid-margin><div class="uk-width-medium-4-5">' . sprintf( _n( '%s has been added to your cart.', '%s have been added to your cart.', sizeof( $titles ), 'woocommerce' ), wc_format_list_of_items( $titles ) ) . '</div>' . $cart_link . '</div>';
    $message = sprintf( '%s', $added_text );
    return $message;
}

您必须使用get_option( 'woocommerce_cart_redirect_after_add' ) == 'yes'而不是is_cart():

add_filter ( 'wc_add_to_cart_message', 'yw_add_to_cart_message', 10, 2 );
function yw_add_to_cart_message($message, $product_id = null) {
    $titles[] = get_the_title( $product_id );
    $titles = array_filter( $titles );
    if ( get_option( 'woocommerce_cart_redirect_after_add' ) == 'yes' ) {
        $cart_link  = '<a href="' . WC_Cart::get_checkout_url() . '"><i class="uk-icon-check-square-o"></i> ' . __( 'Checkout', 'woocommerce' ) . '</a>';
    } else {
        $cart_link  = '<a href="' . WC_Cart::get_cart_url() . '"><i class="uk-icon-shopping-cart"></i> ' . __( 'View Cart', 'woocommerce' ) . '</a>';
    }
    $added_text = '<div class="uk-grid uk-grid-collapse" data-uk-grid-margin><div class="uk-width-medium-4-5">' . sprintf( _n( '%s has been added to your cart.', '%s have been added to your cart.', sizeof( $titles ), 'woocommerce' ), wc_format_list_of_items( $titles ) ) . '</div><div class="uk-width-medium-1-5 uk-text-right">' . $cart_link . '</div></div>';
    $message = sprintf( '%s', $added_text );
    return $message;
}
