How to skip cart page on woocomerce for certain pr

问题:

I added this to my functions.php file :

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;
}

But now, all the products are re-directing strait to check-out. I would like to have this option only in one product. Is that a way I can add a product ID to that same filer?

Thank you!

You need to get the product when It is just added to cart , then check if for this product you want to redirect the cart page to checkout page . You need to change $desire_product = 'certain_product'; line on below code and It will definitely work.

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;
    }
}

There are a few action hooks as well that you can use, for eg: woocommerce_add_to_cart which passes the product id to the callback function:

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;   
    }
}

I wrote a little plugin for this, sharing it here. The plugin adds a small checkbox to the product metabox, so you can specify which products should trigger the automatic skip to checkout. Basically using the same woocommerce_add_to_cart_redirect filter as in the other answers, but providing the admin backend option to determine which products trigger the redirection.
