In Woocommerce we can use apply coupon functionality to improve sales in two ways,
- Customers can manually enter a coupon code and refresh the Cart and see their discount apply
- You can do that automatically (or “programmatically” as we say in the dark web) by enabling coupons when a user adds a product to the WooCommerce Cart.
All you’ve got to do is create a coupon, and then a PHP function will do the whole work. Automation is the best option to get more sales in ecommerce!
Move Coupon Form Under “Proceed to Checkout” on WooCommerce Cart Page
add_action( 'woocommerce_before_cart', codeamend_apply_coupon);
function codeamend_apply_coupon() {
$coupon_code = 'freecoupon';
if ( WC()->cart->has_discount( $coupon_code ) ) return;
WC()->cart->apply_coupon( $coupon_code );
wc_print_notices();
}
Apply a Coupon Programmatically for specific product is added in the Cart
add_action( 'woocommerce_before_cart', 'codeamend_apply_matched_coupons' );
function 'codeamend_apply_matched_coupons' () {
$coupon_code = 'freecoupon';
if ( WC()->cart->has_discount( $coupon_code ) ) return;
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
// this is your product ID
$autocoupon = array( 456);
if ( in_array( $cart_item['product_id'], $autocoupon ) ) {
WC()->cart->apply_coupon( $coupon_code );
wc_print_notices();
}
}
}
Note:
- Create a coupon code that you want to apply once a certain product is added to cart (go to WooCommerce / Coupons / Add New and decide your coupon code. For example “freecoupon”, which is the coupon code we will use later in the PHP snippet).
- Identify your product ID (go to WordPress / Products and hover onto the product you want to use the coupon with. Whatever ID shows in the URL bar, take a note. In our example, we will target product ID = “456”)
