* Hello,
* I have added a custom field to my invoice. I calculate this field in funcion.
php and send it to the order. The problem comes with the mail that is sent to
the client. This field is not displayed. However, it does show if I download
the invoice directly from the order in woocommerce backoffice or from the plugin
settings
* Thanks in advance
* Regards

* Hi [@tomasp98](https://wordpress.org/support/users/tomasp98/),
* Could you please share the code snippet you are using to display the custom field
on your PDF invoice?

* Of course, here is the code snipet
* ```wp-block-code
Presupuesto: order_number(); ?>
Cliente: custom_field('billing_first_name'); ?> custom_field('billing_last_name'); ?> billing_email(); ?>
Fecha: invoice_date(); ?>
Delegacion: custom_field('billing_wcj_checkout_field_2'); ?>
```
* The only field that is not showing me is the billing_wcj_checkout_field_2. I
can see it in the page preview in the plugin, but it is not sent correctly when
the invoice is sent to the mail
* This is the function I use to assign the value
* ```wp-block-code
add_action( 'woocommerce_thankyou', 'bbloomer_alter_checkout_fields_after_order', 10, 1 );
function bbloomer_alter_checkout_fields_after_order( $order_id ) {
$order = wc_get_order( $order_id );
$delegacion = '';
// TARGET-ZIP-CODE
$zonaTest= array( '12564', '23453');
// User ZIP-CODE
$user_zip_zone = $order->get_shipping_postcode();
if(empty($user_shipping_postcode))
$user_zip_zone = $order->get_billing_postcode();
if ( in_array( $user_zip_zone, $zonaTest)) {
$delegacion = 'test test / test@test.com / test';
update_post_meta( $order_id, '_billing_wcj_checkout_field_2', $delegacion );
}
}
```

* Thanks for providing those code snippets, [@tomasp98](https://wordpress.org/support/users/tomasp98/).
* However, I’m afraid the first one would return an error, unless you have edited
it before paste it here.
* Anyway, I realized that you’re using the meta key there without the underscore,
that is, `billing_wcj_checkout_field_2` instead of `_billing_wcj_checkout_field_2`
* Please add the underscore before the meta key to check if the value is displaying
in all contexts.
* If this does not work, please send the complete code, so I can understand better
what it’s happening.

* I have tried but still, I can’t get the field to be displayed in the attachment.
However, I do see the value in the woocommerce backoffice. I can also see it
on the invoice preview. The problem comes when the automatic mail is sent with
the attached file, it disappears there. The field contains value because I can
see it in the order details. Could it be that it has something to do with the
function? The mail is being executed before the function and that is why when
the attachment is sent the value will be null. But I dont know if thats the problem
* Here is the code of the invoice.php
* ```wp-block-code
table class="tabla100">
Presupuesto previo (no vinculante)
|
[logo]
|
```

* Thanks for providing more details, [@tomasp98](https://wordpress.org/support/users/tomasp98/).
* I can see now the reason why this is happening: You’re adding the custom value
AFTER the email is sent. To solve this, you have to save the value for `$delegacion`,
BEFORE the email is sent.
* Try using the `woocommerce_checkout_create_order` action hook instead, like this:
* ```wp-block-code
add_action( 'woocommerce_checkout_create_order', 'bbloomer_alter_checkout_fields_after_order', 10, 2 );
function bbloomer_alter_checkout_fields_after_order( $order, $data ) {
$delegacion = '';
// TARGET-ZIP-CODES
$zonaTest = array( '12564', '23453');
// Customer ZIP-CODE
$customer_zip_zone = ! empty( $order->get_shipping_postcode() ) ? $order->get_shipping_postcode() : $order->get_billing_postcode();
if ( in_array( $customer_zip_zone, $zonaTest ) ) {
$delegacion = 'test test / test@test.com / test';
$order->update_meta_data( '_billing_wcj_checkout_field_2', $delegacion );
}
}
```
