Remove Coupon Field if Total is Zero

The PHP code in this premium download enables you to remove the coupon field on the cart and checkout pages if the total is zero. You can use the following PHP code to remove the coupon field on cart and checkout pages using WooCommerce.

// remove coupon field on the cart and checkout pages
add_filter( 'woocommerce_coupons_enabled', 'remove_coupon_field_on_cart_checkout' );
function remove_coupon_field_on_cart_checkout( $enabled ) {

    if ( is_cart() || is_checkout() ) {

    $enabled = false;

    }

    return $enabled;
}

The above code disables the coupon field regardless of the total or subtotal in the cart or checkout.

If you want to remove the coupon field when the cart or checkout total is zero, you’ll need to make several checks and use more advanced coding which is available in this premium download.
