Obtain coupon info

[info17]

How to obtain coupon info in functions?

i.e.
Coupon: Buy *** 4 Get *** free

I’d like to get *** and 4(number) to show a message on product page.
number be dynamic depend on items in the cart so static message is not I want.

Minimum amount of matching items: get_post_meta( $coupon_id, '_wjecf_min_matching_product_qty', true ) (Where $coupon_id is the id of the coupon)

Ids of the products that must be matched: $coupon->product_ids (Where $coupon is the WC_Coupon object)

Free product ids: WJECF_API()->get_coupon_free_product_ids( $coupon ) (Where $coupon is the WC_Coupon object, coupon id or coupon code)

Thank you.
But in order to match product id with coupon, I have to gather all coupon data but single coupon with code.

[Soft79]

Yes, you’d have to query all existing coupons for that.

See https://www.skyverge.com/blog/get-a-list-of-all-woocommerce-coupons/.

Thank you.

Is there anyway I can set certain product as free gift dynamically through a hook?
I want to change the product for free gift programmatically depend on situation but user select manually.

Hi,

the product id’s are retrieved using this call: get_post_meta( $coupon_id, '_wjecf_free_product_ids', true ). It will go through the filter apply_filters( "get_{$meta_type}_metadata", null, $object_id, $meta_key, $single ); in wp-includes/post.php.

So you can probably use the following snippet to manipulate the product ids:

add_filter( 'get_post_metadata', 'my_get_post_metadata', 10, 4 );
function my_get_post_metadata ( $meta_value, $object_id, $meta_key, $single ) {
  if ( $meta_key == '_wjecf_free_product_ids' ) {
    //EXAMPLE: replace the product id by 123
    $meta_value = 123;
  }
  return $meta_value;
}

You can use $object_id to retrieve the WC_Coupon object. (It’s the coupon id)

I’d like to use Auto Coupon option but I want to let customer select free gift manually on other page than cart.
(So I don’t want to show gift selection element on cart page)
But I want free goods that is single selection to be added automatically.

How to configure this?

[Soft79]

The free gift is saved in the session. You can read the currently selected free item using:

WJECF_API()->get_session_selected_product( $coupon_code )

Setting the free item is not yet in the API of the plugin, but you can use the following method:

WJECF()->get_plugin('WJECF_Pro_Free_Products')->set_session_selected_product( $coupon_code, $product_id )

Thank you.
How do I disable free gift selection on cart page?
Modify /template/cart/select-free-product.php?

[Soft79]

You can override that file by placing it in wp-content/themes/YOUR-CHILD-THEME/woocommerce-auto-added-coupons/cart/select-free-product.php. Just place an empty file there.

Do the same for wp-content/themes/YOUR-CHILD-THEME/woocommerce-auto-added-coupons/checkout/select-free-product.php .

Make sure a free gift has been selected upon checkout. Otherwise the user can’t checkout.

Is it possible to restrict rule to be applied to certain product using a hook?

I’m using this extension of WooCommerce Subscription
woocommerce-subscribe-all-the-things
https://github.com/Prospress/woocommerce-subscribe-all-the-things

Since this extension handles regular product and subscription as one but variation, I can not filter out from GUI.
I need to check see if cart item has this value:
cart[id][wccsub_data][active_subscription_scheme_id]

[Soft79]

Use the woocommerce_coupon_is_valid filter and return false to invalidate the coupon if the product is not in the cart.

http://hookr.io/filters/woocommerce_coupon_is_valid/

[info17]

Thank you.
But that filter apparently disables coupon itself if there is any match item.
So if customer have both a regular product and a subscription product in the cart, coupon will not be applied to any item.

another filter woocommerce_coupon_is_valid_for_product worked!
