This Pro tutorial provides the steps to modify the query parameter of a Bricks query loop to display slides of posts that are related to entries of a CPT via a Meta Box Relationship field.
Scenario:
CPT: featured-article
Meta Box Relationship: post-featured-articles
from featured-article to post
Requirement:
Show the post title, post excerpt and a button linking to the post's permalink of all unique posts that are connected to the items of Featured Article CPT as slides in Bricks' nestable slider on a static Page (say, the homepage).
Step 1
Install and activate Meta Box and its AIO extensions.
Create the Featured Article CPT having a slug of featured-article.
Step 2
Create a Relationship titled say, "Post -- Featured Articles" from Featured Article to Post.
Do not tick "Reciprocal relationship".
Relationships in Meta Box are bi-directional by default unlike in ACF Pro which needs a separate plugin or code snippet.
Step 3
Create Featured Article CPT entries and select 1 or more related posts for each.
Step 3
Edit your homepage (or any other static Page/template) with Bricks.
Add a Section and inside its Container, a Slider (Nestable) element.
Apply this Dynamic data condition on the Section to ensure that it gets output only if there's at least 1 post that has been selected as a related/connected item for any featured article.
{echo:bl_get_count_posts_related_to_featured_articles}
We shall define this custom function in a bit.
Delete Slides 2 and 3.
Enable query loop on Slide 1. Do not set any query parameters in the builder.
Add a Heading, Basic Text and Button elements inside the Slide 1.
Change Heading's text to:
{post_title}
Change Basic Text's text to:
{post_excerpt}
Change Button's text to Read more →
Link type: Dynamic Data
{post_url}
Step 4
Add the following in child theme's functions.php or a code snippets plugin:
