Woocommerce Bookings - adding custom field to admin email - php

Question

I am having a hard time figuring out how to add my new custom billing field into my admin notification email. I am not a php expert (by any means) so i'm not sure what I messed up or if it is because it's trying to append the field to the general woo commerce admin notification email or the one from the Bookings plugin.
My custom field is working fine on the billing page, it's just getting it into the admin email and preferably into the back-end admin order management area as well?
To be completely honest, I was working on this before Christmas and completely lost track of what and where I was doing.
Thank you in advance!
Here is what I have for code.
/**
* Add the field to the checkout
**/
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');
function my_custom_checkout_field( $checkout ) {
echo '<div id="my_custom_checkout_field"><h3>'.__('Referral Source').'</h3>';
/**
* Output the field. This is for 1.4.
*
* To make it compatible with 1.3 use $checkout->checkout_form_field instead:
$checkout->checkout_form_field( 'my_field_name', array(
'type' => 'text',
'class' => array('my-field-class orm-row-wide'),
'label' => __('Fill in this field'),
'placeholder' => __('Enter a number'),
));
**/
woocommerce_form_field( 'my_field_name', array(
'type' => 'text',
'class' => array('my-field-class form-row-wide'),
'label' => __('How did you hear about us?'),
'placeholder' => __('Please enter how you were referred to our clinic.'),
'required' => true,
), $checkout->get_value( 'my_field_name' ));
echo '</div>';
}
/**
* Update the user meta with field value
**/
add_action('woocommerce_checkout_update_user_meta', 'my_custom_checkout_field_update_user_meta');
function my_custom_checkout_field_update_user_meta( $user_id ) {
if ($user_id && $_POST['my_field_name']) update_user_meta( $user_id, 'my_field_name', esc_attr($_POST['my_field_name']) );
}
/**
* Update the order meta with field value
**/
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ($_POST['my_field_name']) update_post_meta( $order_id, 'My Field', esc_attr($_POST['my_field_name']));
}
/**
* Add the field to order emails
**/
add_filter('woocommerce_email_order_meta_keys', 'my_custom_checkout_field_order_meta_keys');
function my_custom_checkout_field_order_meta_keys( $keys ) {
$keys[] = 'Referral Source';
return $keys;
}
UPDATE:
So here is where I am now. It seams to be working but I think I have a doubled function in there. I believe the last function is the one that is working for adding the custom field to my emails.
/**
* Update the user meta with field value
**/
add_action('woocommerce_checkout_update_user_meta', 'my_custom_checkout_field_update_user_meta');
function my_custom_checkout_field_update_user_meta( $user_id ) {
if ($user_id && $_POST['my_field_name']) update_user_meta( $user_id, 'my_field_name', esc_attr($_POST['my_field_name']) );
}
/**
* Update the order meta with field value
**/
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ($_POST['my_field_name']) update_post_meta( $order_id, 'Referral Source', esc_attr($_POST['my_field_name']));
}
/**
* Add the field to order emails
**/
add_filter('woocommerce_email_order_meta_keys', 'my_custom_checkout_field_order_meta_keys');
function my_custom_checkout_field_order_meta_keys( $keys ) {
$keys[] = 'Referral Source';
return $keys;
}
// WooCommerce 2.3+
function my_custom_email_order_meta_fields( $fields, $sent_to_admin, $order ) {
$fields['_some_field'] = array(
'label' => __( 'Referral Source' ),
'value' => get_post_meta( $order->id, 'my_field_name', true ),
);
return $fields;
}
add_filter('woocommerce_email_order_meta_fields', 'my_custom_email_order_meta_fields', 10, 3 );
add_filter('woocommerce_email_order_meta_keys', 'my_custom_checkout_field_order_meta_keys');
function my_custom_order_meta_keys( $keys ) {
$keys[] = 'Referal Source';
return $keys;
}

Answer 1

This method was updated in WooCommerce 2.3, though it should be backcompatible to your approach. It looks like the key you are adding to the array on the woocommerce_email_order_meta_keys filter does not match the name of the meta key your have updated fall back to a basic array. like you have it, but your key doesn't match the meta key you've updated in the my_custom_checkout_field_update_order_meta() function.
Here's how to add keys to the email in WC 2.3+:
// WooCommerce 2.3+
function kia_email_order_meta_fields( $fields, $sent_to_admin, $order ) {
$fields['_some_field'] = array(
'label' => __( 'Some field' ),
'value' => get_post_meta( $order->id, '_some_field', true ),
);
$fields['_another_field'] = array(
'label' => __( 'Another field' ),
'value' => get_post_meta( $order->id, '_another_field', true ),
);
return $fields;
}
add_filter('woocommerce_email_order_meta_fields', 'kia_email_order_meta_fields', 10, 3 );
