4 Ways to delete a coupon Programmatically in WooCommerce?

1. Delete all coupons created before a certain date in WooCommerce

Let’s consider an online store that offers one-time use coupon codes through automatically generated coupons. As a result, your database would have been accumulated with thousands of coupons. In such cases, the below code snippets help to delete outdated coupons that were created before a certain date. For e.g delete all coupons created before Jan 2022. It ensures that only the most recent and relevant promotions are available and accessed by users, avoiding potential errors or misunderstandings.

$target_date = strtotime('01/01/2022'); // Set the target date to 1st January 2022

// Get all coupons created before the target date
$args = array(
    'posts_per_page' => -1,
    'post_type'      => 'shop_coupon',
    'post_status'    => 'publish',
    'date_query'     => array(
        'before' => date('Y-m-d', $target_date),

$coupons = get_posts($args);

if (!empty($coupons)) {
    foreach ($coupons as $coupon) {
        wp_delete_post($coupon->ID, true);

        // Optionally, log or display a message
        error_log('Coupon ID ' . $coupon->ID . ' deleted because it was created before ' . date('Y-m-d', $target_date));

This code retrieves all coupons created before the specified target date (1st January 2022) and deletes them. Adjust the $target_date variable to your desired date.

Booking & Appointment plugin for WooCommerce is filled with service business-friendly booking features to bridge your customer needs and your offerings, simplify the booking experience, and improve customer experience.

Code Explanation

Creating a Coupon Object:

  • WC_Coupon is a class in WooCommerce that represents a coupon. Here, a new instance of the WC_Coupon class is created, and it’s assigned to the variable $coupon_data.
  • The parameter ‘christmas’ is passed to the constructor, indicating that we want to work with the coupon named ‘christmas’.

Checking if the Coupon Exists:

This conditional statement checks if the id property of the $coupon_data object is not empty. In WooCommerce, a coupon’s id is a unique identifier assigned to it.

Deleting the Coupon:

  • If the coupon exists (as determined by the if condition), the wp_delete_post function is called to delete the coupon post.
  • The $coupon_data->id retrieves the unique identifier of the coupon, and this identifier is passed as an argument to wp_delete_post to specify which post (coupon) to delete.

4. Delete multiple coupons Programmatically in WooCommerce

If you want to delete multiple coupons, you can use an array to store coupon codes and then loop through the array to delete each coupon. Here’s the code to delete multiple coupons:

$coupon_codes = array('COUPON_1', 'COUPON_2', 'COUPON_3');

foreach ($coupon_codes as $coupon_code) {
    $coupon_data = new WC_Coupon($coupon_code);
    if (!empty($coupon_data->id)) {


This post guides you to delete a coupon programmatically under different conditions. Alternatively, you can also apply coupon programmatically in WooCommerce which eliminates the need for customers to remember or manually input coupon codes.
