string	$summary	Custom summary. Set to default summary if empty.
bool	$bot	If true, mark all reverted edits as bot.
array	&$resultDetails	Contains result-specific array of additional values

Deletes the article with database consistency, writes logs, purges caches

Parameters

string	$reason	Delete reason for deletion log
bool	$suppress	Suppress all revisions and log the deletion in the suppression log instead of the deletion log
int \| null	$u1	Unused
bool \| null	$u2	Unused
array \| string	&$error	Array of errors to append to

		User	$user = null )

Do some database updates after deletion.

Parameters

int	$id	The page_id value of the page being deleted
Content \| null	$content	Page content to be used when determining the required updates. This may be needed because $this->getContent() may already return null when the page proper was deleted.
RevisionRecord \| Revision \| null	$revision	The current page revision at the time of deletion, used when determining the required updates. This may be needed because $this->getRevision() may already return null when the page proper was deleted.
User \| null	$user	The user that caused the deletion

◆ doEditContent()

WikiPage::doEditContent	(	Content	$content,
			$summary,
			$flags = 0,
			$originalRevId = false,
		User	$user = null,
			$serialFormat = null,
			$tags = [],
			$undidRevId = 0 )

Change an existing article or create a new article.

Updates RC and all necessary caches, optionally via the deferred update array.

Deprecated: since 1.32, use PageUpdater::saveRevision instead. Note that the new method expects callers to take care of checking EDIT_MINOR against the minoredit right, and to apply the autopatrol right as appropriate.

Parameters

Content	$content	New content
string \| CommentStoreComment	$summary	Edit summary
int	$flags	Bitfield: EDIT_NEW Article is known or assumed to be non-existent, create a new one EDIT_UPDATE Article is known or assumed to be pre-existing, update it EDIT_MINOR Mark this edit minor, if the user is allowed to do so EDIT_SUPPRESS_RC Do not log the change in recentchanges EDIT_FORCE_BOT Mark the edit a "bot" edit regardless of user rights EDIT_AUTOSUMMARY Fill in blank summaries with generated text where possible EDIT_INTERNAL Signal that the page retrieve/save cycle happened entirely in this request.

If neither EDIT_NEW nor EDIT_UPDATE is specified, the status of the article will be detected. If EDIT_UPDATE is specified and the article doesn't exist, the function will return an edit-gone-missing error. If EDIT_NEW is specified and the article does exist, an edit-already-exists error will be returned. These two conditions are also possible with auto-detection due to MediaWiki's performance-optimised locking strategy.

Parameters

bool \| int	$originalRevId,	The ID of an original revision that the edit restores or repeats. The new revision is expected to have the exact same content as the given original revision. This is used with rollbacks and with dummy "null" revisions which are created to record things like page moves.
User \| null	$user	The user doing the edit
string \| null	$serialFormat	IGNORED.
array \| null	$tags	Change tags to apply to this edit Callers are responsible for permission checks (with ChangeTags::canAddTagsAccompanyingChange)
Int	$undidRevId	Id of revision that was undone or 0

Exceptions

MWException

Returns: Status Possible errors: edit-hook-aborted: The ArticleSave hook aborted the edit but didn't set the fatal flag of $status. edit-gone-missing: In update mode, but the article didn't exist. edit-conflict: In update mode, the article changed unexpectedly. edit-no-change: Warning that the text was the same as before. edit-already-exists: In creation mode, but the article already exists.

Extensions may define additional errors.

$return->value will contain an associative array with members as follows: new: Boolean indicating if the function attempted to create a new article. revision: The revision object for the inserted revision, or null.

◆ doPurge()

WikiPage::doPurge ( )

◆ doRollback()

WikiPage::doRollback	(		$fromP,
			$summary,
			$token,
			$bot,
		&	$resultDetails,
		User	$user,
			$tags = null )

Roll back the most recent consecutive set of edits to a page from the same user; fails if there are no eligible edits to roll back to, e.g.

user is the sole contributor. This function performs permissions checks on $user, then calls commitRollback() to do the dirty work

Todo

Separate the business/permission stuff out from backend code

Remove $token parameter. Already verified by RollbackAction and ApiRollback.

Parameters

string	$fromP	Name of the user whose edits to rollback.
string	$summary	Custom summary. Set to default summary if empty.
string	$token	Rollback token.
bool	$bot	If true, mark all reverted edits as bot.
array	&$resultDetails	Array contains result-specific array of additional values 'alreadyrolled' : 'current' (rev) success : 'summary' (str), 'current' (rev), 'target' (rev)
User	$user	The user performing the rollback
array \| null	$tags	Change tags to apply to the rollback Callers are responsible for permission checks (with ChangeTags::canAddTagsAccompanyingChange)

Returns: array Array of errors, each error formatted as array(messagekey, param1, param2, ...). On success, the array is empty. This array can also be passed to OutputPage::showPermissionsErrorPage().

Definition at line 3057 of file WikiPage.php.

References commitRollback(), and wfArrayDiff2().

◆ doSecondaryDataUpdates()

WikiPage::doSecondaryDataUpdates ( array $options = [] )

Do secondary data updates (such as updating link tables).

Secondary data updates are only a small part of the updates needed after saving a new revision; normally PageUpdater::doUpdates should be used instead (which includes secondary data updates). This method is provided for partial purges.

Note: This is a temporary workaround until there is a proper data updater class. It will become deprecated soon.

Parameters

array

$options

recursive (bool, default true): whether to do a recursive update (update pages that depend on this page, e.g. transclude it). This will set the $recursive parameter of Content::getSecondaryDataUpdates. Typically this should be true unless the update was something that did not really change the page, such as a null edit.
triggeringUser: The user triggering the update (UserIdentity, defaults to the user who created the revision)
causeAction: an arbitrary string identifying the reason for the update. See DataUpdate::getCauseAction(). (default 'unknown')
causeAgent: name of the user who caused the update (string, default 'unknown')
defer: one of the DeferredUpdates constants, or false to run immediately (default: false). Note that even when this is set to false, some updates might still get deferred (as some update might directly add child updates to DeferredUpdates).
transactionTicket: a transaction ticket from LBFactory::getEmptyTransactionTicket(), only when defer is false (default: null)

Since: 1.32

◆ doUpdateRestrictions()

WikiPage::doUpdateRestrictions	(	array	$limit,
		array	$expiry,
		&	$cascade,
			$reason,
		User	$user,
			$tags = null )

Update the article's restriction field, and leave a log entry.

This works for protection both existing and non-existing pages.

Parameters

array	$limit	Set of restriction keys
array	$expiry	Per restriction type expiration
int	&$cascade	Set to false if cascading protection isn't allowed.
string	$reason
User	$user	The user updating the restrictions
string \| string[] \| null	$tags	Change tags to add to the pages and protection log entries ($user should be able to add the specified tags before this is called)

Returns: Status Status object; if action is taken, $status->value is the log_id of the protection log entry.

Returns a DerivedPageDataUpdater for use with the given target revision or new content.

This method attempts to re-use the same DerivedPageDataUpdater instance for subsequent calls. The parameters passed to this method are used to ensure that the DerivedPageDataUpdater returned matches that caller's expectations, allowing an existing instance to be re-used if the given parameters match that instance's internal state according to DerivedPageDataUpdater::isReusableFor(), and creating a new instance of the parameters do not match the existign one.

If neither $forRevision nor $forUpdate is given, a new DerivedPageDataUpdater is always created, replacing any DerivedPageDataUpdater currently cached.

Since: 1.32

Parameters

User \| null	$forUser	The user that will be used for, or was used for, PST.
RevisionRecord \| null	$forRevision	The revision created by the edit for which to perform updates, if the edit was already saved.
