Filtering Bricks Posts Query Loop by Meta Box Group’s Radio Subfield Value

In the past we showed how a Bricks posts query loop can be filtered by Meta Box group’s subfield of types text/number and Datepicker here.

This Pro tutorial provides the steps to filter posts when the subfield is Radio type.

Consider this scenario:

CPT: store

Field group:

session (cloneable group)
|__ session_name (text)
|__ session_type (radio) with these choices:
|____ Individual
|____ Duet
|____ Trio

A post can have 1 or more sessions:

Another post:

The objective is to show all the posts for which session type is the specified string i.e., Individual or Duet or Trio.

Step 1

Set up query loop in a Page or Template.

Enable PHP query.

Paste:

$session_type = 'Individual';

// Validate session type
$valid_types = [ 'Individual', 'Duet', 'Trio' ];
if ( ! in_array( $session_type, $valid_types, true ) ) {
  return [ 'post__in' => [ 0 ] ]; // Return empty result for invalid session type
}

return [
  'post_type'      => 'store',
  'posts_per_page' => -1,
  'no_found_rows'  => true,
  'meta_query' => [ // Meta query to filter by session type
    [
      'key'     => 'session',
      'value'   => '"session__type";s:' . strlen( $session_type ) . ':"' . $session_type . '"',
      'compare' => 'LIKE',
    ],
  ]
];

Enter the session type to be filtered by in the first line.

"session__type";s:' . strlen( $session_type ) . ':"' . $session_type . '"

pattern creates a search string that matches the PHP serialized format of the ⁠session__type field within the Meta Box data, including the exact field name, string indicator, character count, and the value itself.

Step 2
