Before Send Content
apply_filters_ref_array( 'vikappointments_before_send_mail_content_{$type}', bool $send, string &$content, mixed $data )
Fires while fetching the body to include within the notification e-mails.
Description
Plugins can use this filter to manipulate at runtime the body of the e-mail notifications.
The dynamic portion of the hook name, $type, refers to the type of event that triggered the e-mail sending.
Here's a list of supported types:
- customer
- admin
- cancellation
- employee
- waitlist
- package
- packadmin
- usernote
This means that, for example, the notification e-mail sent to the administrator, for an appointment, will trigger a filter called vikappointments_before_send_mail_content_admin.
Parameters
- $send
- 
(bool) Use false to prevent the e-mail sending. 
- &$content
- 
(string) The current content of the e-mail. Since the argument is passed as reference, it is possible to manipulate it. 
- $data
- 
(mixed) The entity to notify. In case of a take-away order, the argument will be a VAPOrderAppointmentobject.
The hook might specify additional arguments, which can vary according to the current type.
Example
The example below appends a footer at the end of the e-mail. The footer is added only to the notification e-mail sent to the customers for appointments.
/**
 * Triggers a filter to let the plugins be able to handle the content of the e-mail.
 *
 * The hook name is built as:
 * vikappointments_before_send_mail_content_[type]
 *
 * @param  boolean  $send      False to prevent the e-mail sending.
 * @param  string   &$content  The current e-mail content.
 * @param  object   $order     The appointment details.
