How to apply a coupon programmatically in Woocommerce?

You can apply a coupon programmatically in WooCommerce using the WC_Discounts class provided by WooCommerce. Here’s a code snippet that demonstrates how to apply a coupon programmatically:

Copy code
// Load WooCommerce functions
require_once( ABSPATH . ‘wp-load.php’ );

// Initialize WooCommerce
if ( ! function_exists( ‘WC’ ) ) {
include_once( dirname( __FILE__ ) . ‘/wp-content/plugins/woocommerce/woocommerce.php’ );

// Coupon code to apply
$coupon_code = ‘your_coupon_code’;

// Get the WC_Coupon object
$coupon = new WC_Coupon( $coupon_code );

// Check if the coupon is valid
if ( $coupon->is_valid() ) {
// Apply the coupon to the current user’s cart
$coupon_result = WC()->cart->apply_coupon( $coupon_code );

// Check if the coupon was applied successfully
if ( $coupon_result === true ) {
echo “Coupon applied successfully.”;
} else {
echo “Failed to apply coupon.”;
} else {
echo “Coupon is not valid.”;
Replace ‘your_coupon_code’ with the actual coupon code you want to apply. This script first checks if the coupon is valid, then applies it to the current user’s cart using WC()->cart->apply_coupon(). Finally, it checks if the coupon was applied successfully and outputs a message accordingly.

Make sure to include this code in a suitable place within your WordPress environment, such as a custom plugin or a theme’s functions.php file.

Please note that running this code outside the context of a WordPress request (e.g., in a standalone PHP script) might require additional setup to properly load WordPress and WooCommerce functionalities.

You were not leaving your cart just like that, right?
