在 Woocommerce 结账后数据已经存在时禁用用户配置文件更新

Question

I have a store where users have data registered in the profile. In the checkout page there is the possibility to change the data that is automatically filled (pull of the profile).

I would like: if for example the customer enters another address or another email, that this data would NOT be saved in the profile.

Answer 1

The following will disable the user profile to be updated if the data already exist when an order is placed (see in WC_Checkout process_customer() method source code ) :

add_filter( 'woocommerce_checkout_update_customer_data', 'checkout_update_customer_data_callback', 10, 2 );
function checkout_update_customer_data_callback( $boolean, $checkout ) {
    if ( get_current_user_id() > 0 ) {
        $customer = new WC_Customer( get_current_user_id() );
        $first_name = $customer->get_first_name();

        // When customer data already exist, don't update it when an order is processed
        if ( ! empty( $first_name ) ) {
            return false;
        }
    }
    return $boolean;
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.
