Metadata

Unless otherwise configured, Midgard automatically adds information like creation time, author, approval status and so on to every MgdSchema object and tracks them in dedicated DB columns. In PHP, this is available in the metadata property:

$article = new midcom_db_article($id);
$revisor = new midcom_db_person($article->metadata->revisor);
$revised = strftime('%x %X', $article->metadata->revised);
echo 'Article "' . $article->title . '" was last updated on ' . $revised . ' by ' . $revisor->name . "\n";
