WooCommerce provides an online store for customers to purchase any items or course on your website requirement.

when users can purchase online any items or course then we want to send out product-related information and access details for the online product.

WooCommerce emails are provided to add a custom email for sharing custom product details.

Let’s started the Implementation of custom email.

 

Step 1: Add the below code in the YOUR-CHILD-THEME functions.php file.

/**
 * custom email template for booking reminder on last day 
 */
add_filter( 'woocommerce_email_classes', 'custom_bkap_init_emails' ,99);
function custom_bkap_init_emails($email_classes){

    require_once( get_stylesheet_directory() . '/includes/class-bkap-email-booking-reminder-on-lastday.php' );
    $email_classes['BKAP_Email_Booking_Reminder_On_Lastday'] = new BKAP_Email_Booking_Reminder_On_Lastday();

    return $email_classes;
}

 

Step 2: Create a file in the YOUR-CHILD-THEME of ‘includes/class-bkap-email-booking-reminder-on-lastday.php’.

<?php
class BKAP_Email_Booking_Reminder_On_Lastday extends WC_Email {

  function __construct() {

    $this->template_plain = 'emails/plain/customer-booking-reminder-on-lastday.php';  

    // Call parent constructor
    parent::__construct();

    // Other settings
    $this->template_base = get_stylesheet_directory_uri()."/woocommerce/emails";
