if (!isset($wgPublicCat)) $wgPublicCat = 'Public';
- Pattern to match with domain to determine if client accessing private wiki or public website
if (!isset($wgPublicCatPrivatePattern)) $wgPublicCatPrivatePattern = '/^wiki\\./';
$wgExtensionCredits['other'][] = array( 'name' => 'PublicCat', 'author' => 'User:Nad', 'description' => 'Divides wiki into private and public by domain name, but allows unrestricted access to articles in a public category.', 'url' => 'http://www.mediawiki.org/wiki/Extension:PublicCat', 'version' => PUBLICCAT_VERSION );
- Hook in after article and title prepared
- - should be able to hook in earlier than this,
- - but note that it must be a hook that always executes, even for specialpages
$wgHooks['OutputPageBeforeHTML'][] = 'wfPublicCatValidate';
- Determine if the request is private or public from the domain and pattern
$wgPublicCatRequestIsPrivate = preg_match($wgPublicCatPrivatePattern,$_SERVER['HTTP_HOST']); $wgPublicCatRequestIsPublic = !$wgPublicCatRequestIsPrivate;
- Disable all actions except view for anonymous users
$wgGroupPermissions['*']['createaccount'] = false; $wgGroupPermissions['*']['read'] = $wgPublicCatRequestIsPublic; $wgGroupPermissions['*']['edit'] = false; $wgGroupPermissions['*']['createpage'] = false; $wgGroupPermissions['*']['createtalk'] = false;
- Allow unrestricted access to login and css's
$wgWhitelistRead = array('Special:Userlogin','-'); if (eregi('\\.css$',$_REQUEST['title'])) $wgWhitelistRead[] = $_REQUEST['title'];
- If request is public, restrict action to view, raw or render
if ($wgPublicCatRequestIsPublic) { if ($_REQUEST['action'] != 'view' && $_REQUEST['action'] != 'raw' && $_REQUEST['action'] != 'render') $_REQUEST['action'] = 'view'; }
- Function to die returing a 404 not found error
function wfPublicCat404() { global $wgOut; $wgOut->disable(); header('HTTP/1.0 404 Not Found'); $err = '<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
Not Found
The requested URL was not found on this server!
'; if (in_array('Content-Encoding: gzip',headers_list())) $err = gzencode($err); echo $err; }
- Function to check if passed a title is in a category
function wfPublicCatInCat(&$title,$cat) { if (!is_object($title)) $title = Title::newFromText($title); if (!is_object($title)) return false; $id = $title->getArticleID(); $db = &wfGetDB(DB_SLAVE); $cl = $db->tableName('categorylinks'); $result = $db->query("SELECT 0 FROM $cl WHERE cl_from = $id AND cl_to = '$cat'"); if ($result instanceof ResultWrapper) $result = $result->result; return is_array(mysql_fetch_row($result)); }
- Return a 404 not found error if request is public but requested title is not in the public cat
function wfPublicCatValidate() { global $wgPublicCat,$wgPublicCatRequestIsPublic,$wgTitle; if ($wgPublicCatRequestIsPublic && !wfPublicCatInCat($wgTitle,$wgPublicCat)) wfPublicCat404(); }
