		Language	$lang,
		bool	$activeOnly = self::TAG_SET_ACTIVE_ONLY,
		bool	$useAllTags = self::USE_ALL_TAGS )

static

Get information about change tags for tag filter dropdown menus.

This manipulates the label and description of each tag, which are parsed, stripped and (in the case of description) truncated versions of these messages. Message parsing is expensive, so to detect whether the tag list has changed, use getChangeTagListSummary() instead.

Parameters

MessageLocalizer	$localizer
Language	$lang
bool	$activeOnly
bool	$useAllTags

Returns: array[] Same as getChangeTagListSummary(), with messages parsed, stripped and truncated

◆ getChangeTagListSummary()

static ChangeTags::getChangeTagListSummary	(	MessageLocalizer	$localizer,
		Language	$lang,
		bool	$activeOnly = self::TAG_SET_ACTIVE_ONLY,
		bool	$useAllTags = self::USE_ALL_TAGS )

static

Get information about change tags, without parsing messages, for tag filter dropdown menus.

By default, this will return explicitly-defined and software-defined tags that are currently active (have hits)

Message contents are the raw values (->plain()), because parsing messages is expensive. Even though we're not parsing messages, building a data structure with the contents of hundreds of i18n messages is still not cheap (see T223260#5370610), so this function caches its output in WANCache for up to 24 hours.

Returns an array of associative arrays with information about each tag:

name: Tag name (string)
labelMsg: Short description message (Message object, or false for hidden tags)
label: Short description message (raw message contents)
descriptionMsg: Long description message (Message object)
description: Long description message (raw message contents)
cssClass: CSS class to use for RC entries with this tag
helpLink: Link to a help page describing this tag (string or null)
hits: Number of RC entries that have this tag

This data is consumed by the mediawiki.rcfilters.filters.ui module, specifically mw.rcfilters.dm.FilterGroup and mw.rcfilters.dm.FilterItem.

Parameters

MessageLocalizer	$localizer
Language	$lang
bool	$activeOnly
bool	$useAllTags

Returns: array[] Information about each tag

◆ getDisplayTableName()

static ChangeTags::getDisplayTableName ( )

static

Get the name of the change_tag table to use for modifyDisplayQuery().

This also does first-call initialisation of the table in testing mode.

Deprecated: since 1.41 use ChangeTags::CHANGE_TAG or 'change_tag' instead. Note that directly querying this table is discouraged, try using one of the existing functions instead. Hard-deprecated since 1.44.

		&	$conds,
		&	$join_conds,
		&	$options,
			$filter_tag = '',
		bool	$exclude = false )

static

Applies all tags-related changes to a query.

Handles selecting tags, and filtering. Needs $tables to be set up properly, so we can figure out which join conditions to use.

WARNING: If $filter_tag contains more than one tag and $exclude is false, this function will add DISTINCT, which may cause performance problems for your query unless you put the ID field of your table at the end of the ORDER BY, and set a GROUP BY equal to the ORDER BY. For example, if you had ORDER BY foo_timestamp DESC, you will now need GROUP BY foo_timestamp, foo_id ORDER BY foo_timestamp DESC, foo_id DESC.

Deprecated: since 1.41 use ChangeTagsStore::modifyDisplayQueryBuilder instead. Hard-deprecated since 1.44.

Parameters

string \| array	&$tables	Table names, see Database::select
string \| array	&$fields	Fields used in query, see Database::select
string \| array	&$conds	Conditions used in query, see Database::select
array	&$join_conds	Join conditions, see Database::select
string \| array	&$options	Options, see Database::select
string \| array \| false \| null	$filter_tag	Tag(s) to select on (OR)
bool	$exclude	If true, exclude tag(s) from $filter_tag (NOR)

◆ restrictedTagError()

static ChangeTags::restrictedTagError	(	$msgOne,
		$msgMulti,

staticprotected

Helper function to generate a fatal status with a 'not-allowed' type error.

Parameters

string	$msgOne	Message key to use in the case of one tag

◆ showTagEditingUI()

static ChangeTags::showTagEditingUI ( Authority $performer )

static

Indicate whether change tag editing UI is relevant.

Returns true if the user has the necessary right and there are any editable tags defined.

This intentionally doesn't check "any addable || any deletable", because it seems like it would be more confusing than useful if the checkboxes suddenly showed up because some abuse filter stopped defining a tag and then suddenly disappeared when someone deleted all uses of that tag.

Parameters

Authority $performer

Returns: bool

static

Get a short description for a tag.

The description combines the label from tagShortDescriptionMessage() with the link from tagHelpLink() (unless the label already contains some links).

Parameters

string	$tag
MessageLocalizer	$context

Returns: string|false Tag description or false if tag is to be hidden.

Since: 1.25 Returns false if tag is to be hidden.

			$params = null,
		?RecentChange	$rc = null,
		?UserIdentity	$user = null )

static

Add and remove tags to/from a change given its rc_id, rev_id and/or log_id, without verifying that the tags exist or are valid.

If a tag is present in both $tagsToAdd and $tagsToRemove, it will be removed.

This function should only be used by extensions to manipulate tags they have registered using the ListDefinedTags hook. When dealing with user input, call updateTagsWithChecks() instead.

Deprecated: since 1.41 use ChangeTagsStore::updateTags(). Hard-deprecated since 1.44.

Parameters

string \| array \| null	$tagsToAdd	Tags to add to the change
string \| array \| null	$tagsToRemove	Tags to remove from the change
int \| null	&$rc_id	The rc_id of the change to add the tags to. Pass a variable whose value is null if the rc_id is not relevant or unknown.
int \| null	&$rev_id	The rev_id of the change to add the tags to. Pass a variable whose value is null if the rev_id is not relevant or unknown.
int \| null	&$log_id	The log_id of the change to add the tags to. Pass a variable whose value is null if the log_id is not relevant or unknown.
string \| null	$params	Params to put in the ct_params field of table 'change_tag' when adding tags
RecentChange \| null	$rc	Recent change being tagged, in case the tagging accompanies the action
UserIdentity \| null	$user	Tagging user, in case the tagging is subsequent to the tagged action

Returns: array Index 0 is an array of tags actually added, index 1 is an array of tags actually removed, index 2 is an array of tags present on the revision or log entry before any changes were made

◆ updateTagsWithChecks()

static ChangeTags::updateTagsWithChecks	(		$tagsToAdd,
			$tagsToRemove,
			$rc_id,
			$rev_id,
			$log_id,
			$params,
		string	$reason,
		Authority	$performer )

static

Adds and/or removes tags to/from a given change, checking whether it is allowed first, and adding a log entry afterwards.

Includes a call to ChangeTags::canUpdateTags(), so your code doesn't need to do that. However, it doesn't check whether the *_id parameters are a valid combination. That is up to you to enforce. See ApiTag::execute() for an example.

Extensions should generally avoid this function. Call ChangeTagsStore->updateTags() instead, unless directly handling a user request to add or remove tags from an existing revision or log entry.

Parameters

array \| null	$tagsToAdd	If none, pass [] or null
array \| null	$tagsToRemove	If none, pass [] or null
int \| null	$rc_id	The rc_id of the change to add the tags to
int \| null	$rev_id	The rev_id of the change to add the tags to
int \| null	$log_id	The log_id of the change to add the tags to
string \| null	$params	Params to put in the ct_params field of table 'change_tag' when adding tags
string	$reason	Comment for the log
Authority	$performer	who to check permissions and give credit for the action

Returns

Status If successful, the value of this Status object will be an object (stdClass) with the following fields:

logId: the ID of the added log entry, or null if no log entry was added (i.e. no operation was performed)
addedTags: an array containing the tags that were actually added
removedTags: an array containing the tags that were actually removed
