Manual:Special:Log 用に記録を登録する

このページでは Special:Log に操作を記録する方法を示します。 （アプリケーションへのログ関連はManual:ログ記録の構造化 で説明します。）

例

これは拡張機能の Special:Log の記録項目のコードの書き方を説明しています。 Special:Log ページに表示される記録メッセージは絞り込みができ、例えば記録名、利用者、タイトル、日付の範囲を条件にします。

拡張機能設定ファイルの処理

extension.json で以下が有効なはずです:

{
    "LogTypes": [ "foo" ],
    "LogNames": {
        "foo": "foo-name"
    },
    "LogHeaders": {
        "foo": "foo-header"
    },
    "LogActionsHandlers": {
        "foo/*": "LogFormatter"
    }
}

コアの記録の環境設定についてはDefaultSettings.php を参照してください。

$wgLogTypes[] = 'foo';

// You can still set
// $wgLogNames['foo'] = 'foo-name';
// $wgLogHeaders['foo'] = 'foo-header';
// 
// But you don't need to, if you follow this naming convention for your i18n messages:
//
// log-name-foo
//   for the Special:Log log name that appears in the drop-down on the Special:Log page
//
// log-description-foo
//   for the Special:Log description that appears on the Special:Log page when you filter 
//   logs on this specific log name

$wgLogActionsHandlers['foo/bar'] = 'LogFormatter';

// Or if you want catch-all, do:
$wgLogActionsHandlers['foo/*'] = 'LogFormatter';

// Or if you need some extra logic, you can write your own formatter
// (subclassing LogFormatter) and do:
$wgLogActionsHandlers['foo/*'] = 'FooLogFormatter';

In i18n/en.json file

{
	"log-name-foo": "Foo log",
	"log-description-foo": "These events track when Foo events happen in the system.",
	"logentry-foo-bar": "$1 {{GENDER:$2|did bar}} to page $3"
}

メッセージの説明文書 (qqq.json):

{
	"log-name-foo": "The Special:Log log name that appears in the drop-down on the Special:Log page",
	"log-description-foo": "The Special:Log description that appears on the Special:Log page when you filter logs on this specific log name",
	"logentry-foo-bar": "The template of the log entry message"
}

拡張機能コードの処理

// Anywhere in your code where you want to generate a log entry

$logEntry = new ManualLogEntry( 'foo', 'bar' ); // Log action 'bar' in the Special:Log for 'foo'
$logEntry->setPerformer( $user ); // User object, the user who performed this action
$logEntry->setTarget( $this ); // The page that this log entry affects, a Title object
$logEntry->setComment( $reason ); // Optional, user provided comment

// Optionally, add additional parameters for use in the log entry’s i18n message.
// Numbering should start from 4 and can be used in the message as $4, $5 and so on.
//
// Indexes $1, $2, and $3 are reserved and provide the username and target page parameters for the messages.
// $1 is a reference to the user page and user talk page in the wiki
// $2 is used to determine the gender of the user for any gender specific messages
// $3 is a reference to the page on which the action took place
//
// If you want to store stuff that should not be available in messages, don’t prefix the array key with a number and don’t use the colons.
// 
// The format is index:formatspecifier:name.
// Format specifier is currently unused, but in future you could say for example
// that this param is a number, format it according to the user language.
// Name is just for giving identifier for the value, and helps to debug issues
// versus unindexed list of parameters.
$logEntry->setParameters( [
	'4::paramname' => 'customparam',
	'hiddenparam' => 'ugly stuff',
] );

// We're not done yet, we need to insert the log entry into the database.
// Insert adds it to the logging table and returns the id of that log entry.
$logid = $logEntry->insert();

// Optionally, publish the log entry in recent changes and the UDP feed of recent changes
// if we want. UDP feed is mainly used for echoing the recent change items into IRC.
// publish() takes second param with values 'rcandudp' (default), 'rc' and 'udp'.
$logEntry->publish( $logid );

リンクの追加

To add a link to log entries, you should pass the page name etc. in the log parameters, and format that in your LogFormatter using makePageLink(). その他の方法を使用すると、非 HTML 出力 (例: IRC への UDP フィード) が壊れてしまいます。
