Examples

#1 Synchronize (delete) additional post data

Suppose we have a plugin that stores some post data in a separate database table named codex_postmeta. This data must be deleted when the post is deleted.

add_action( 'admin_init', 'wpdocs_codex_init' );

function wpdocs_codex_init() {
	add_action( 'delete_post', 'wpdocs_codex_sync', 10 );
}

function wpdocs_codex_sync( $pid ) {
	global $wpdb;

	$sql = $wpdb->prepare( 'DELETE FROM codex_postmeta WHERE post_id = %d', $pid );

	$wpdb->query( $sql );
}
