Check if coupon is applied in woo commerce
From your example, something like this might work. This is untested, but should give you a step in the right direction:
add_action('woocommerce_applied_coupon', 'apply_product_on_coupon');function apply_product_on_coupon( ) { global $woocommerce; $coupon_id = '12345'; $free_product_id = 54321; if(in_array($coupon_id, $woocommerce->cart->get_applied_coupons())){ $woocommerce->cart->add_to_cart($free_product_id, 1); }}
global $woocommerce;if (!empty($woocommerce->cart->applied_coupons)){ //print_r($woocommerce->cart->applied_coupons); - keys of coupons here}
This might be an ages issue but an easy solution is to use
WC()->cart->applied_couponsThis return array lists of applied coupons, you can then use foreach, for or in_array to check applied coupons.
Hope that helps
