One-to-many relationship on "bay_mb_relationships"

Hi,

If you want to force only one connection from one side of a relationship, please set 'max_clone' => 1 to the field on that side, like this:

add_action( 'mb_relationships_init', function () {
    MB_Relationships_API::register(
        array(
            'id'   => 'workout_to_workout_exercises',
            'from' => array(
                'object_type' => 'post',
                'post_type' => 'workout',
                'field' => array(
                    'max_clone' => 1, // Limit to 1 connection only.
                ),
            ),
            'to'   => array(
                'object_type' => 'post',
                'post_type' => 'workout_exercises',
            ),
        )
    );
} );

Thank you for your kind words and your feedback. We keep improving the plugin and will try our best to make it more useful for you!

Hi Robert,

The extension only helps you to create the relation between the posts, but thanks for the idea, I will discuss with the developer team to support the property 'required' => 1 to check this box not empty like the required fields.
