Date de début, date de fin, metabox pour les types d'articles personnalisés d'événements

Voulez-vous ajouter trois metaboxes à vos types de publication personnalisés d'événements ? Bien qu'il existe probablement un plugin pour cela, nous avons créé un extrait de code rapide que vous pouvez utiliser pour ajouter des metaboxes de date de début, de date de fin et de lieu pour les types de publication personnalisés d'événements.

Instructions :

Il vous suffit d'ajouter ce code au fichier functions.php de votre thème ou dans un plugin spécifique au site :

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' );
 
// Metabox HTML
 
function ept_event_date($post, $args) {
    $metabox_id = $args['args']['id'];
    global $post, $wp_locale;
 
    // Use nonce for verification
    wp_nonce_field( plugin_basename( __FILE__ ), 'ep_eventposts_nonce' );
 
    $time_adj = current_time( 'timestamp' );
    $month = get_post_meta( $post->ID, $metabox_id . '_month', true );
 
    if ( empty( $month ) ) {
        $month = gmdate( 'm', $time_adj );
    }
 
    $day = get_post_meta( $post->ID, $metabox_id . '_day', true );
 
    if ( empty( $day ) ) {

    }
