Site Reviews provides an option to display a link in the review to the page that the review has been assigned to.
For example:
This will assign new reviews submitted in the form to the current page:
[site_reviews_form assign_to=post_id]
And this will display all reviews that have been assigned to the current page:
[site_reviews assigned_to=post_id]
And to display the link of the page in the reviews, use the provided setting:
However, If you are assigning reviews to categories instead of to pages, then Site Reviews will not display the category that the review has been assigned to.
Site Reviews v3.6 will allow you to access the category ID of the review (if assigning to categories) from the review.php template. However, currently this is not possible.
