如果在woocommerce中为空，则将账单地址保存到自定义结帐字段

Question

我遵循了一个教程，关于如何包括在woocommerce的结账自定义字段，一切工作如预期，但我想保存完整的账单地址到这个自定义字段，如果没有填写。

这就是我的东西

function cloudways_save_extra_checkout_fields( $order_id, $posted ){
// don't forget appropriate sanitization if you are using a different field type
if( isset( $posted['cloudways_text_field'] ) ) {
    update_post_meta( $order_id, '_cloudways_text_field', sanitize_text_field( $posted['cloudways_text_field'] ) );

if(empty($posted['cloudways_text_field']))
    {
    // it's empty!
        update_post_meta( $order_id, '_cloudways_text_field', sanitize_text_field( $posted['cloudways_text_field'] ) );
    }
else
    {
        update_post_meta( $order_id, '_cloudways_text_field', sanitize_text_field( $posted['cloudways_text_field'] ) );
    }    

}

} add_action( 'woocommerce_checkout_update_order_meta'，'cloudways_save_extra_checkout_fields'，10，2 )；

但是如果没有填写，我不知道如何将帐单地址数组保存到这个自定义文本字段中。

提前谢谢。

您可以尝试将地址构建到数组中，并将其保存在字段中。或者您也可以将其构建为字符串，这取决于您希望字段包含什么数据，字符串或数组。下面是一个数组的示例：

function cloudways_save_extra_checkout_fields( $order_id, $posted ) {
    // don't forget appropriate sanitization if you are using a different field type
    if ( isset( $posted['cloudways_text_field'] ) ) {
        update_post_meta( $order_id, '_cloudways_text_field', sanitize_text_field( $posted['cloudways_text_field'] ) );

        if ( empty( $posted['cloudways_text_field'] ) ) {
            $billing_address_array = array(
                'billing_address_1' => $posted['billing_address_1'],
                'billing_address_2' => $posted['billing_address_2'],
                'billing_city'      => $posted['billing_city'],
                'billing_postcode'  => $posted['billing_postcode'],
                'billing_state'     => $posted['billing_state'],
                'billing_country'   => $posted['billing_country'],
            );
            update_post_meta( $order_id, '_cloudways_text_field', wc_clean( $billing_address_array ) );
        } else {
            update_post_meta( $order_id, '_cloudways_text_field', sanitize_text_field( $posted['cloudways_text_field'] ) );
        }
    }
}
add_action( 'woocommerce_checkout_update_order_meta', 'cloudways_save_extra_checkout_fields', 10, 2 );
