How do i make the custom fields public in rest API?
I have added a custom field to the rest api. the challenge is - The metadata is returned when i am signed in my browser. if i try as public using incognito mode - it doesn't return the custom field. I was wondering how do i make it public so that i can access without loggin in. i tried following what is mentioned here
Still not working. Can you let me know what am i missing?
My Full code :
/**
Changes Related to adding Additional Field "thumbnail_image" in Post
*/
function addCustomField_register_fields() {
register_rest_field('post',
'thumbnail_image',
array(
'get_callback' =>'get_custom_field',
'update_callback' => null,
'schema' => null
));
}
function get_custom_field($post, $field_name , $request) {
return get_post_meta($post['id'], 'thumbnail_image', true);
}
add_action('rest_api_init', 'addCustomField_register_fields');
//* Make the field public */
add_filter( 'rest_api_allowed_public_metadata', 'allow_thumbnail_metadata' );
function allow_thumbnail_metadata() {
// only run for REST API requests
if ( ! defined( 'REST_API_REQUEST' ) || ! REST_API_REQUEST )
return $allowed_meta_keys;
$allowed_meta_keys[] = 'thumbnail_image';
return $allowed_meta_keys;
}
