– I have custom post type “producers”.
– And i have custom post type “movies”.
– I have relationship field “movies_of_this_producer”.
On the page of edit/creation new post of custom post type “movies” i have this relationship field “movies_of_this_producer”. And in this relationship field “movies_of_this_producer” i can choose a corresponding “producer” post.
As a result, I have the correct relationship between “producers” posts and “movies” posts.
For example, on the site I have post “Steven Spielberg” (post of custom post type “producers”), which is associated via relationship field “movies_of_this_producer” with 5 posts: “Jaws”, “Jurassic Park”, “Schindler’s List”, “The Terminal”, “Bridge of Spies” (5 posts of custom post type “movies”).
Now i need to get for each “producers” post – the number of related “movies” posts (“movies” posts, related with the “producers” post via relationship field “movies_of_this_producer”)
Question: How to get the number of related “movies” posts for each “producers” post? What should be the code for this?
Hi @danbo
You can simply do a count on the relationship field.
<?php echo $movie_count = count(get_field('movies_of_this_producer')); ?>
Hi @jonathan
It’s work correctly in the case, when I need to get from Relationship field the number of posts – of custom post type “movies”: – given that on the page of edit/creation new post of custom post type “movies” i have this relationship field “movies_of_this_producer”. And in this relationship field “movies_of_this_producer” i can choose a corresponding “producer” post.
But if i need to get (from Relationship field) the number of posts – of custom post type “producers”: – it’s work incorrectly.
*Posts of custom post type “producers” – have the “reverse” relationship with posts of custom post type “movies” via relationship field “movies_of_this_producer”.
I created a new topic with a detailed description of this problem and with my code examples: http://support.advancedcustomfields.com/forums/topic/how-to-get-the-number-of-posts-from-relationship-field-for-reverse-posts/
Tell me please, what code should be used in case with posts, that have “reverse” relationship?
