10. Custom Fields of Orders

Map custom WC checkout fields with custom Zoho Sales Order fields.

*Note: in this tutorial, we assume you have already configured Custom Fields in Zoho and in WooCommerce. If not, please follow the Zoho Inventory documentation, as well as install a Checkout Custom Fields plugin in your WooCommerce store.

1. Install the Checkout Field Editor plugin and create the custom fields in either Billing/Shipping/Additional, depending on your requirements.

2. Go to CommerceBird > Zoho Inventory > Custom Fields and map each Woo Custom Field with its respective Zoho Field. Simply type the Zoho custom field label the same way that you typed in Zoho Inventory > Settings > Items > Field Customisation.

End result:

Simply fill in the WooCommerce field name on the left side and the Zoho Field Label on the right side and click on save. Voila! Now you have enabled complete orders if you use custom fields!

How to sync the order’s Payment Method to Zoho:

The payment method is a standard field in Woo and not a custom field, so you will need to create a custom called “payment_method” for the order and then hide it on the Frontend with some CSS.
After that step, simply copy below code and paste it into your child theme – functions.php or custom plugin.

add_action( 'woocommerce_checkout_update_order_meta', 'cmbird_checkout_field_update_order_meta' );
function cmbird_checkout_field_update_order_meta( $order_id ) {
$order = wc_get_order( $order_id );
$method = $order->get_payment_method();
$order->update_meta_data( 'payment_method', $method );
$order->save();
}

Sending Phone number as separate custom field:

add_action( 'woocommerce_checkout_update_order_meta', 'cmbird_checkout_field_update_order_meta' );
function cmbird_checkout_field_update_order_meta( $order_id ) {
if ( isset($_POST['billing_phone']) ) {
$phone = sanitize_text_field($_POST['billing_phone']);
$order = wc_get_order( $order_id );
$order->update_meta_data( 'billing_phone', $phone ); // Store it in meta
$order->save(); // Save order changes
}
}
