Return values

// return_format: 'slug'
// "product"

// return_format: 'label'
// "Product"

// return_format: 'object'
// WP_Post_Type object — access $pt->name, $pt->label, etc.

Multi-select

Returns an array of values in the chosen format.

$types = get_field('feed_post_types');
// ['post', 'product', 'event']  (return_format: 'slug')

Usage

Dynamic WP_Query using the selected type

$post_type = get_field('featured_post_type', 'option'); // from options page

if ($post_type) {
    $posts = get_posts([
        'post_type'      => $post_type,
        'posts_per_page' => 6,
    ]);
}

Multi-select: loop across post types

$types = get_field('index_post_types', 'option'); // return_format: 'slug', multiple

if ($types) {
    $all_posts = get_posts([
        'post_type'      => $types,
        'posts_per_page' => -1,
        'fields'         => 'ids',
    ]);
}

Feeding into a REST API endpoint

$type = get_field('api_post_type', 'option');

if ($type) {
    $url = rest_url('wp/v2/' . $type);
    $response = wp_remote_get($url);
}

Validating a submitted post type

$selected = get_field('search_scope'); // slug
$valid    = get_post_types(['public' => true]);

if (in_array($selected, $valid, true)) {
    // Safe to use in a query
}
