The wc_order_email
class or function doesn't exist in WooCommerce, so I have updated your question.
What you are looking at is $email
variable argument (the WC_Email
current type object). It's mostly defined everywhere in templates and hooks.
To get the usable current Email ID as a variable you will simply use $email_id = $email->id
…
To get the current Email ID of your custom emails, you should use this code (just for testing):
add_action( 'woocommerce_email_order_details', 'get_the_wc_email_id', 9, 4 );
function get_the_wc_email_id( $order, $sent_to_admin, $plain_text, $email ) {
// Will output the email id for the current notification
echo '<pre>'; print_r($email->id); echo '</pre>';
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
You will get one of the following:
For WooCommerce default notifications:
new_order
customer_on_hold_order
customer_processing_order
customer_completed_order
customer_refunded_order
customer_partially_refunded_order
cancelled_order
failed_order
customer_reset_password
customer_invoice
customer_new_account
customer_note
low_stock
no_stock
For WooCommerce Subscriptions:
new_renewal_order
new_switch_order
customer_processing_renewal_order
customer_completed_renewal_order
customer_on_hold_renewal_order
customer_completed_switch_order
customer_renewal_invoice
cancelled_subscription
expired_subscription
suspended_subscription
For WooCommerce Bookings:
new_booking
booking_reminder
booking_confirmed
booking_pending_confirmation
booking_notification
booking_cancelled
admin_booking_cancelled
For WooCommerce Memberships:
WC_Memberships_User_Membership_Note_Email
WC_Memberships_User_Membership_Ending_Soon_Email
WC_Memberships_User_Membership_Ended_Email
WC_Memberships_User_Membership_Renewal_Reminder_Email
WC_Memberships_User_Membership_Activated_Email
Once you get the correct email ID slug for your custom email notification you can use it on any following hook (instead of overriding email templates):
woocommerce_email_header
(2 arguments: $email_heading
, $email
)
woocommerce_email_order_details
(4 arguments: $order
, $sent_to_admin
, $plain_text
, $email
)
woocommerce_email_order_meta
(4 arguments: $order
, $sent_to_admin
, $plain_text
, $email
)
woocommerce_email_customer_details
(4 arguments: $order
, $sent_to_admin
, $plain_text
, $email
)
woocommerce_email_footer
(1 argument: $email
)
HERE an example of code where I target "New order" email notifications only:
add_action( 'woocommerce_email_order_details', 'add_custom_text_to_new_order_email', 10, 4 );
function add_custom_text_to_new_order_email( $order, $sent_to_admin, $plain_text, $email ) {
// Only for "New Order" email notifications (to be replaced by yours)
if( ! ( 'new_order' == $email->id ) ) return;
// Display a custom text (for example)
echo '<p>'.__('My custom text').'</p>';
}
Code goes in functions.php file of your child theme (or in a plugin).
