Formatting custom field data using dynamic data (date) filters?

1

Hi! I am working on a plugin that creates a custom post type and some custom fields.

A couple of the fields are dates.

I tried using the tag filters to format the date, i.e., {cf_ewr_event_start_date:F j, Y}, but to no avail.

By default it is printing out like this:

YYYY-MM-DD (e.g., 2024-06-11), which is a fairly good starting point for a typical date format, but perhaps incomplete?

Here is my code:

// Register meta fields with REST API
function erw_register_meta_fields() {
$meta_keys = array(
‘ewr_event_start_date’ => ‘Event Start Date’,
‘ewr_event_end_date’ => ‘Event End Date’,
‘ewr_event_start_time’ => ‘Event Start Time’,
‘ewr_event_end_time’ => ‘Event End Time’,
‘ewr_ticket_price’ => ‘Ticket Price’,
‘ewr_max_ticket_quantity’ => ‘Max Ticket Quantity’,
‘ewr_ticket_addon’ => ‘Ticket Add-on’
);

foreach ($meta_keys as $meta_key => $description) {
    register_post_meta('event', $meta_key, array(
        'type' => 'string',
        'description' => $description,
        'single' => true,
        'show_in_rest' => array(
            'schema' => array(
                'type' => 'string',
                'context' => array('view', 'edit', 'embed'),
            ),
        ),
        'auth_callback' => function() {
            return current_user_can('edit_posts');
        }
    ));
}

}
add_action(‘init’, ‘erw_register_meta_fields’);

// Expose custom fields in REST API response
function erw_expose_custom_fields_in_rest($response, $post, $request) {
if ($post->post_type === ‘event’) {
$meta_fields = array(
‘ewr_event_start_date’,
‘ewr_event_end_date’,
‘ewr_event_start_time’,
‘ewr_event_end_time’,
‘ewr_ticket_price’,
‘ewr_max_ticket_quantity’,
‘ewr_ticket_addon’
);

    foreach ($meta_fields as $meta_field) {
        $meta_value = get_post_meta($post->ID, $meta_field, true);
        if (!empty($meta_value)) {
            $response->data['meta'][$meta_field] = $meta_value;
        }
    }
}

return $response;

}
add_filter(‘rest_prepare_event’, ‘erw_expose_custom_fields_in_rest’, 99, 3);

I am curious to know if there is a way I can format or indicate that this field should be able to be formatted as a date by Bricks, similar to how current_date can be, such that the filters will work?

E.g., my fields are strings… According to WP documentation here are the possible types available:

'string' , 'boolean' , 'integer' , 'number' , 'array' , and 'object'

Any other suggestions?

Thanks :slight_smile:

I’m experiencing the same issue. I’ve added standard datetime fields via Metabox, and they’re correctly stored in ISO8601 format - clearly identifiable as dates. Yet, Bricks completely ignores them in filters, merely outputting the raw database value.

Sure, I can write a simple PHP function to format the output correctly, but isn’t the whole point of Bricks’ filtering system to handle this natively? Why should post_date be the only field that works seamlessly while others require unnecessary workarounds? This limitation seems like an oversight that restricts the flexibility Bricks is designed to offer.
