How to Apply Coupon when a radio button is clicked on The WooCommerce Product Page?

Amazon displays a coupon option, instead of just automatically showing a discounted price, gives shoppers an extra incentive to make the purchase right away.

Do you want to do similar in your WooCommerce store?

Let’s create coupons in the marketing section of the WooCommerce admin section. Here we are making two discount codes: 10%OFF & 20%OFF

// Add radio button below Add to Cart button
add_action( 'woocommerce_after_add_to_cart_button', 'add_coupon_radio_button', 10 );
function add_coupon_radio_button() {
    	echo '<br /><input type="radio" id="10%OFF" name="add_coupon" value="10%OFF">
		<label for="10%OFF">Apply a coupon:<b>10%OFF</b> by checking this box!</label><br />';
		echo '<input type="radio" id="20%OFF" name="add_coupon" value="20%OFF">
		<label for="20%OFF">Apply a coupon:<b>20%OFF</b> by checking this box!</label><br />';
}

Once the coupons displayed on the product page, we need to apply coupon when radio button is clicked.

// Apply coupon when radio button is clicked
add_action( 'woocommerce_add_to_cart', 'apply_coupon_on_radio_button_clicked', 10, 6 );
function apply_coupon_on_radio_button_clicked( $cart_item_key, $product_id, $quantity, $variation_id, $variation, $cart_item_data ) {
    if ( isset( $_POST['add_coupon'] ) ) {
    	if ($_POST['add_coupon'] == '10%OFF') {
    		// WC()->cart->remove_coupons(); // Remove all remove coupons
    		WC()->cart->remove_coupon('20%OFF');
        	$coupon_code = '10%OFF'; // Replace with your coupon code
        	$coupon = new WC_Coupon( $coupon_code );
        	WC()->cart->apply_coupon( $coupon_code );
        }
        if ($_POST['add_coupon'] == '20%OFF') {
        	// WC()->cart->remove_coupons(); // Remove all remove coupons
        	WC()->cart->remove_coupon('10%OFF');
        	$coupon_code = '20%OFF'; // Replace with your coupon code
        	$coupon = new WC_Coupon( $coupon_code );
        	WC()->cart->apply_coupon( $coupon_code );
        }
    }
}

Now user can decide which coupon code to use. What is the use-case? Now, shoppers can decide what type of discounts they want.
