Template usage
To output the media in the frontend, use the rwmb_meta() helper function:
$media = rwmb_meta( $field_id );
echo $value;
This helper function will display the oembed content, e.g. if the value is a Youtube URL, it will display the full Youtube video player.
In case you want to get the URL of the field, use this code:
$url = rwmb_get_value( $field_id );
echo $url

Use the filter as follows:
add_filter( 'rwmb_oembed_not_available_string', function( $message ) {
$message = 'Sorry, what you are looking here is not available.';
return $message;
} );
Developers also can hide the message with CSS, since it’s wrapped into a div.rwmb-oembed-not-available. Simply put this code into your theme or in Customize > Additional CSS:
.rwmb-oembed-not-available {
display: none;
}
