Hi Developers!

I’m trying to do a relationship query that contains the next:

I have two custom post types named Application and Platform, so, the Application has a repeater where this contains a post object (the relation with a Platform) and others random fields.

So, In a page where the user filters some data, I need to filter Applications that have selected a specific Platform inside a repeater. And for this, I was trying this query but is not working for me:

$platform_id = $_GET['platform_id'];

$args = array(
    'post_type' => 'applications',
    'meta_query' => array(
        array(
            'key' => 'platform_informations_%_platform',
            'value' => '"' . $platform_id . '"',
            'compare' => '='
        )
    )
);

$applications = new WP_Query( $args );
// here go the loop

So, the platform_informations is the repeater name, and the platform is the name of the field that contains the platform post object.

Any ideas why this does not work?
