Publication date year only

  • Hi. I have created a website and have setup a few books. I would like to show the year of publication only, not a specific date. Would it be possible to have a filter hook for this, so there isn’t a _sanitize_meta_data filter, so it’s optional to use the _sanitize_date function?

    The page I need help with: [log in to see the link]

  • Hi, @vayu!

    You could filter the date format for books only, like this:

    add_filter( 'pre_option_date_format', 'custom_author_pro_date' );
/**
 * Use the year only for book publish dates.
 *
 * @param string|bool $date The original date formatting string.
 * @return string|bool
 */
function custom_author_pro_date( $date ) {
	if ( ! is_admin() && 'books' === get_post_type() ) {
		return 'Y';
	}

	return $date;
}
