This Pro tutorial covers how posts of a Bricks query loop can be filtered to show only the ones whose true / false or checkbox type of sub field, which is inside a group-type field is equal to true (1).
ACF
Add a meta query in your query loop
where my_group is the group name and featured is the field name within that group.
Meta Box
For performance reasons, Meta Box stores all sub fields of a group in a single row as a serialized string in the database. As such, it is difficult or not straight-forward to query posts by a sub field value when using MB.
So what we can do is write a function that loops through all posts and returns a list of post IDs for which a specified True / False type sub field of a specified group field is true. Then set this function as the value of the post__in query parameter.
Add the following in child theme‘s functions.php (w/o the opening PHP tag) or a code snippets plugin:
function get_mb_featured_post_ids( $group_id, $sub_field_id ) {
$featured_post_ids = [];
$posts = get_posts( [
'post_type' => 'post',
'numberposts' => 100, // a large number
] );
foreach ( $posts as $post ) {
$group = rwmb_meta( $group_id, [], $post->ID );
$checkbox = $group[ $sub_field_id ] ?? 0;
if ( $checkbox ) {
$featured_post_ids[] = $post->ID;
}
}
return $featured_post_ids;
}In the Bricks editor set up your query loop.
Specify the post type (if other than post).
Enable PHP query editor and paste:
return [
'post__in' => get_mb_featured_post_ids( 'my_group', 'featured' ),
'posts_per_page' => 100, // a large number
];where my_group is the group ID and featured is the sub field ID.
