Hi,
The helper function rwmb_meta() does not support argument query_args
. Some field types (image, file, etc.) or extension (MB Settings Page, MB Custom Table) support passing the argument.
If you want to get the published post only, you should create a new WP_Query and use the helper function inside the loop.
$args = array(
'post_type' => 'post',
'post_status' => 'publish',
);
$my_query = new WP_Query( $args );
while( $my_query->have_posts() ) {
// Loop in here
$my_query->the_post();
$field_value = rwmb_meta( 'field_id', '', get_the_ID() );
}
