Fecha de inicio, fecha de finalización, metabox para tipos de entradas personalizadas de eventos

¿Quieres añadir tres metaboxes a tus custom post types de eventos? Si bien es probable que haya un plugin para esto, hemos creado un fragmento de código rápido que se puede utilizar para agregar la fecha de inicio, fecha de finalización, y la ubicación metabox para eventos tipos de entradas personalizadas.

Instrucciones:

Todo lo que tienes que hacer es añadir este código al archivo functions.php de tu tema o en un plugin específico del sitio:

function ep_eventposts_metaboxes() {
    add_meta_box( 'ept_event_date_start', 'Start Date and Time', 'ept_event_date', 'event', 'side', 'default', array( 'id' => '_start') );
    add_meta_box( 'ept_event_date_end', 'End Date and Time', 'ept_event_date', 'event', 'side', 'default', array('id'=>'_end') );
    add_meta_box( 'ept_event_location', 'Event Location', 'ept_event_location', 'event', 'side', 'default', array('id'=>'_end') );
}
add_action( 'admin_init', 'ep_eventposts_metaboxes' );
