Add Customer to Coupon On The Fly

[Heidi Maskelyne]

at present global coupons are being abused so we have in place below code which i wanted to run past you to check if this is the correct way of doing it.

at present if a customer purchases a sample pack or they are just a new customer they will get 20% off with a coupon. Upon checkout and order received page we do this.

$coupon_id     = wc_get_coupon_id_by_code('example'); 	 
$addcoupon_id  = explode(',',get_post_meta($coupon_id , '_wjecf_customer_ids', true));
update_post_meta($coupon_id, '_wjecf_customer_ids', array_merge(array($user_id), $addcoupon_id));

is there a better way of doing ? im unsure until i watch someone checkout if the “_wjecf_customer_ids” will grow with customer or just replace i think it will grow. unsure if i do need to explode or not.

Thanks
Mike

my code isnt working as expected can i get some help please?

IT DOES NOT APPEND THE LIST IT REMOVES ALL FROM LIST AND JUST ADDS THE NEW CUSTOMER

I have sorted and fixed

$coupon_id= wc_get_coupon_id_by_code('example'); 	 
$add_coupon_id = array_merge(explode(',', get_post_meta($coupon_id, '_wjecf_customer_ids', true)), array($user_id));
update_post_meta($coupon_id, '_wjecf_customer_ids',implode(',', $add_coupon_id));

Thanks
