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 VAPOrderAppointment object.

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.
