Advanced Custom Fields in WooCommerce Email templates

Question

I am using Advanced Custom Fields (ACF) plugin in WooCommerce and I have set a custom field named "tracking-no".

How can I display the value of this custom field in the Woocommerce template emails/customer-completed-order.php?

I am using this code:

<?php
    if(get_field('tracking-no'))
    {
        echo '<p>' . get_field('tracking-no') . '</p>';
    }
?>

But I doesn't get anything.

Thanks

In your WooCommerce template you should get first the order ID as argument in get_field():

<?php
    // Get the $order ID (WooCommerce version compatibility)
    if ( version_compare( WC_VERSION, '3.0', '<' ) ) {
        $order_id = int_val( $order->id ); // Older than 3.0
    } else {
        $order_id = int_val( $order->get_id() ); // 3.0+
    }

    $tracking_num = get_field('tracking-no', $order_id );

    if( $tracking_num ){
        echo '<p>' . $tracking_num . '</p>';
    }
?>

You can also use instead any email notification hook that you can find on this template, this way:

add_action( 'woocommerce_email_order_details', 'my_custom_field_in_completed_notification', 10, 4 );
function my_custom_field_in_completed_notification( $order, $sent_to_admin, $plain_text, $email ){
    // Get the $order ID (WooCommerce version compatibility)
    if ( version_compare( WC_VERSION, '3.0', '<' ) ) {
        $order_id = int_val( $order->id ); // Older than 3.0
    } else {
        $order_id = int_val( $order->get_id() ); // 3.0+
    }

    $tracking_num = get_field('tracking-no', $order_id );
    if( $tracking_num ){
        echo '<p>' . $tracking_num . '</p>';
    }
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

In this case we don't override WooCommerce templates. You can also use that 2 similar hooks:

woocommerce_email_order_meta
woocommerce_email_customer_details
