跳过错误“您无法将其他“产品”添加到您的购物车。并重定向到结帐页面

Question

我正在尝试对单独销售的产品执行以下操作，当它显示错误时，您无法添加更多产品，因为它们已经被添加。此错误会重定向到结账页面。

add_filter( 'woocommerce_product_add_to_cart_url', 'misha_fix_for_individual_products', 10, 2 );
function misha_fix_for_individual_products( $add_to_cart_url, $product ){
 
    if( $product->get_sold_individually() // if individual product
    && WC()->cart->find_product_in_cart( WC()->cart->generate_cart_id( $product->id ) ) // if in the cart
    && $product->is_purchasable() // we also need these two conditions
    && $product->is_in_stock() ) {
        $add_to_cart_url = wc_get_checkout_url();
    }
 
    return $add_to_cart_url;
 
}

Answer 1

我找到了解决方案，这对我有用。

add_filter( 'woocommerce_add_to_cart_sold_individually_found_in_cart', 'bypass_add_to_cart_sold_individually_found_in_cart', 10, 2 );

function bypass_add_to_cart_sold_individually_found_in_cart( $found_in_cart, $product_id ) {
    if ( $found_in_cart ) {
        wp_redirect(wc_get_checkout_url());
        
        exit;
    }
    
    return $found_in_cart;
}
