If you want to create a relationship between two objects on your website, the MB Relationships from Meta Box can help you. In this practice, we’ll create a bi-directional relationship between Courses and Instructors post type for example. In addition, we also display them on the page with the help of Bricks Builder.

Here is an archive page I created. It includes courses and the name of instructors who contributed to each course.

Before Getting Started

We have two separate custom post types: Courses and Instructors. In this case, the relationship is to link the courses to their instructors, and also link each instructor to the courses to which they contributed. This bi-directional relationship will be shown on the both singular page of each post type and the archive page for Courses.

So, we need the Meta Box core plugin to have a framework to create custom post types, custom fields, and relationships. You can download it directly from wordpress.org.

Moreover, we need some Meta Box extensions for the advanced features:

  • MB Custom Post Type: to create custom post types for the courses and instructors;
  • MB Relationships: to create relationships between these post types;
  • Meta Box Builder: to have an intuitive UI on the backend to create custom fields and relationships;
  • MB Admin Columns (optional): to display the related courses and related instructors in the dashboard.

You can install these extensions individually or use Meta Box AIO to have them all.

The last one is Bricks to build the pages.

Create the Custom Post Types

Go to Meta Box > Post Types to create a new post type for the instructors, and another one for courses.

Go to Meta Box, Post Types to create a new post type for the instructors, and courses

Then, you will see new menus displayed in the Admin Dashboard. They’re your post types.

Create Custom Fields

If you want to add some custom fields for each post type to save some extra information about the courses or the instructors, just go to Meta Box > Custom Fields to create fields as usual. In this practice, I just add some fields for the courses.

go to Meta Box, Custom Fields to create custom fields

After creating all the wanted fields, go to the Settings tab, set the Location as Post type, and select the post type you want to apply the fields to it.

Create Relationships

Go to Meta Box > Relationships to create the relationships between the Courses and Instructors post types.

Go to Meta Box, Relationships to create the relationships between the Courses and Instructors post types

You can enter all the settings for the relationship and each side of it in two sections.

In this practice, the relationship is bidirectional so you can put the post types not in order. Beside that, because they are post types, set the Object Type as Post in both two sections.

In the Post type option, choose the post type you want to create a relationship. For example, I set the Instructor in the From section, and the other is the Course.

Because I activated the MB Admin Columns extension before, I have this option in both two sections of the relationship’s settings.

I set it to show which courses are related to an Instructor and vice versa.

when you check the option, you can see which courses are related to an Instructor

In the Field tab, you can set the label for the relationship section in the post editor.

There’ll be a box at the right sidebar to choose which instructor is related to the current post in the Course post type and vice versa. It displays as a field, this will make sense when you get posts from this field in the next step.

After publishing, go to a post editor and you can choose more than one course in the Related Course section.

It’ll be the same when you add related instructors for a course.

In the dashboard, all the information will display like this.

Display the Relationship

In this practice, we’ll display this relationship on both singular pages of the Course post type and Instructor post type; and on the archive page where all the courses are listed.

Normally, we set the Type as Posts to get posts in the post type we want. However, in this case, we want to show posts that are set in the relationship, so it’s different. You’ll see an option is ‘MB Relationship’ along with the name of the relationship you created before. Choose it.

  1. Hi MB team, this is a very useful example.

    The only point I'd need to know is how I can display more than one instructor names per course in a simple comma-separated list. Can you please add this?

    1. It's similar to the tutorial: https://www.youtube.com/watch?v=uUz_sgcvJY8 (in 13:28)
      With Bricks, you can use Query editor (PHP) and paste this code to get the instructor, then use the Post title element to display instructor's name. Choose the Suffix as the comma.
      return [
      'post_type' => 'instructor',
      'posts_per_page'=>-1,
      'relationship' => [
      'id' => 'instructor-to-course',
      'from' => get_the_ID()
      ],
      ];
