HI.
I solve a similar problem, only with tags.
I searched for a solution for almost 2 hours (I didn’t find it), I didn’t find any examples, but I managed to solve my problem myself!
If it helps:
is_main_tag – field name
product_tag_ – suffix (described at the bottom of the page https://www.advancedcustomfields.com/resources/get_field/).
$post_id = false; // current post
$post_id = 1; // post ID = 1
$post_id = “user_2”; // user ID = 2
$post_id = “category_3”; // category term ID = 3
By analogy, he suggested and tried his type (woocommerce) of taxonomy and helped!
$ value = get_field (“is_main_tag”, ‘product_tag _’. $ id);
In your case, it will most likely help:
$ value = get_field (“name_of_your_field”, ‘product_cat_’. $ id);
I hope this helps you!
Good luck colleague!
