Review system with ACF

  • Hi,

    I am trying to build a review system using ACF.

    Reviews (custom post type) is attached to a Product (custom post type). A review is composed of 4 items (integer). For each review, I’ve created a calculated field : (item 1 + item 2 + item 3 + item 4) / 4 = customer rating.

    That works well.

    Now, I am trying to display (using a shortcode) the global average rating that would consist of : (customer rating 1 + custom rating 2 + … + customer rating n) / n

    Any idea on how to achieve this ?


  • Did you ever figure this out? I’m trying to do the same thing.

    One way is to set a field called avg rating that can hold num of reviews and total score on the post that the reviews are attached to and whenever a new review is approved to hook into it with acf/save_post (
    and update the field of the main post with the new values adding +1 to total and +customer rating to the total score.
    then on shortcode just do the simple total/num_reviews
