如何仅针对某些产品跳过 woocommerce 上的购物车页面？

Question

我将此添加到我的 functions.php 文件中：

add_filter ('woocommerce_add_to_cart_redirect', 'woo_redirect_to_checkout');
function woo_redirect_to_checkout() {
$checkout_url = WC()->cart->get_checkout_url();
return $checkout_url;
}

但是现在，所有的产品都在重新定向结账。我希望仅在一种产品中使用此选项。我可以通过这种方式将产品 ID 添加到同一个文件管理器吗？

谢谢！

我为此写了一个小插件，在这里分享。该插件向产品元框添加了一个小复选框，因此您可以指定哪些产品应触发自动跳至结帐。基本上使用与其他答案相同的 woocommerce_add_to_cart_redirect 过滤器，但提供管理后端选项来确定哪些产品触发重定向。

您还可以使用一些操作挂钩，例如：woocommerce_add_to_cart 将产品 ID 传递给回调函数：

add_action( 'woocommerce_add_to_cart', 'custom_add_to_cart', 10, 2 );

function custom_add_to_cart( $cart_item_key, $product_id ) {
    // replace 123 with a valid product id
    if( 123 == $product_id ) {
        wp_redirect( WC()->cart->get_checkout_url() );
        exit;   
    }
}

您需要在产品刚刚添加到购物车时获取该产品，然后检查您是否要针对该产品将购物车页面重定向到结帐页面。您需要在下面的代码中更改$desire_product = 'certain_product'; 行，它肯定会起作用。

add_filter( 'woocommerce_add_to_cart_redirect', 'woo_redirect_checkout' );

function woo_redirect_checkout() {
    global $woocommerce;
    $desire_product = 'certain_product';
    //Get product ID
    $product_id = (int) apply_filters( 'woocommerce_add_to_cart_product_id', $_POST['add-to-cart'] );

    //Check if current product is subscription
    if ( $product_id == $desire_product ){
        $checkout_url = $woocommerce->cart->get_checkout_url();
        return $checkout_url;
        exit;
    } else {
        $cart_url = $woocommerce->cart->get_cart_url();
        return $cart_url;
        exit;
    }
}
