为什么要返回整个计费地址？

Question

我试图最大程度地减少帐单地址，如果“客户已经购买了某些东西或从他的帐户中保存了他的地址”

它有效，但它不呼应地址_2它只是回应了整个计费地址 ，我做错了什么？

//hide billing address from checkout if the address is already entered before
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
    if( is_user_logged_in() && has_billing()){
        unset($fields['billing']);
        $fields['billing'] = array();
    }
    return $fields;
}

// Check the meta of Postcode and Country if they are entered.
function has_billing($user_id = false){
            if(!$user_id)
                $user_id = get_current_user_id();

            $shipping_postcode = get_user_meta( $user_id, 'billing_postcode', true );
            $shipping_country = get_user_meta( $user_id, 'billing_country', true );

            // Fetch more meta for the condition has needed.  
            if($shipping_postcode && $shipping_country){
                return $address_fields['address_2']; 
            }           
}

首先，从您的代码来看，尚不清楚如何定义$ adville_fields
根据 https://woocommerce.io.github.io/code-reference/classes/classes/classes/classes/classes/ woocommerce.html

$billing_address_2  = WC()->customer->get_billing_address_2();
