CMS Basics

Baseline: main 23.0+. Features newer than baseline are marked Since.

Site management layer above the framework — sites, templates, menus, content areas. Landing sites / Sites24: skill bitrix-landing.

Sites (Multisite)

ORM tablet: \Bitrix\Main\SiteTable → table b_lang (main/lib/SiteTable.php). Legacy: CSite.

Key fields: LID (primary, e.g. s1), NAME, DIR, DOC_ROOT, SERVER_NAME, SITE_NAME, LANGUAGE_ID, CULTURE_ID, ACTIVE, DEF.

$site = \Bitrix\Main\SiteTable::getRow([
    'filter' => ['=LID' => SITE_ID],
    'select' => ['LID', 'DIR', 'SERVER_NAME', 'DOC_ROOT', 'LANGUAGE_ID'],
]);
