I'm trying to force the user to apply a coupon for one specific product/category only.
I found the following code but am having endless trouble getting it to run. I suspect it's old code and am unsure what to change. It's supposed to go in the functions file, so I've been using the Code Snippets plugin to run it
// Force Coupon codes for Woocommerce
add_action('woocommerce_check_cart_items', 'mandatory_coupon_code');
function mandatory_coupon_code()
{
// set Here your categories IDs, slugs or names
$categories = array(18,19,87);
$found = false;
// Loop through cart items
foreach ( WC()->cart->get_cart() as $cart_item )
if( has_term( $categories, 'product_cat', $cart_item['product_id'] ) ){
// Product category found in cart items
$found = true;
// Exit from loop
break;
}
}
$coupons = WC()->cart->get_applied_coupons();
// The Notice is displayed for that product categories when no mandatory coupon has been entered
if( count( $coupons ) > 0 && $found )
wc_add_notice( __( 'A coupon code is mandatory for this product.', 'woocommerce' ), 'error' );
I will truly appreciate any help I can get here.
