W3TPL/sysdata

About

"Sysvar" syntax is a way of accessing various bits of information provided by the system under different circumstances. Any value prefixed with "@" will be treated as a reference to system data (yes, there are potential conflicts with this form... working on that; they are resolvable).

Names

• @title: information about the current page title
  • .id: the article ID
  • .full': namespace:subject
  • .subject': just the part after the namespace and before any slashes (i.e. not the subpage name)
  • .name': just the part after the namespace (including any subpages)
  • .url': URL for the page
• @row: information about the current data row
  • .name: name of the field (column) to access
• @mem: current memory usage, for debugging (this is a kluge and should probably be made more useful or eliminated)
• @user: information about the user currently viewing the page
  • .login: user's login -- $wgUser->getName()
  • .dbkey: user's login in URL format -- $wgUser->getTitleKey();
  • .id: user's database ID -- $wgUser->getID();
  • .can: user has permission to do specified action? -- $wgUser->isAllowed(action);
  • .rights: user rights -- $wgUser->getRights(), converted to a prefix-separated list
  • .email: user's email address, if known)-- $wgUser->getEmail()
  • .name: user's full name, if known -- $out = $wgUser->getRealName();
• @query.name: value of $_GET["name"]
• @post.name: value of $_POST["name"]
• @env.name: value of $_ENV["name"]
