$revRecord = null,
User $user = null )

Do some database updates after deletion.

Parameters
int$idThe page_id value of the page being deleted
Content | null$contentPage content to be used when determining the required updates. This may be needed because $this->getContent() may already return null when the page proper was deleted.
RevisionRecord | Revision | null$revRecordThe current page revision at the time of deletion, used when determining the required updates. This may be needed because $this->getRevisionRecord() may already return null when the page proper was deleted. Passing a Revision is deprecated since 1.35
User | null$userThe user that caused the deletion

Definition at line 3156 of file WikiPage.php.

References $content, User\getName(), NS_FILE, and wfDeprecated().

◆ 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$contentNew content
string | CommentStoreComment$summaryEdit summary
int$flagsBitfield: 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. This is used with reverts and with dummy "null" revisions which are created to record things like page moves. The new revision does not have to have the exact same content as the given original revision, an additional check is made to determine whether these edits really match. In case they don't, $originalRevId is set to false by this method.
User | null$userThe user doing the edit
string | null$serialFormatIGNORED.
array | null$tagsChange tags to apply to this edit Callers are responsible for permission checks (with ChangeTags::canAddTagsAccompanyingChange)
int$undidRevIdId of the last 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. Trying to access this Revision object is deprecated since 1.35 revision-record: The RevisionRecord object for the inserted revision, or null.

Since
1.21

◆ doEditUpdates()

WikiPage::doEditUpdates ( $revisionRecord,
User $user,
array $options = [] )

Update links tables, site stats, search index and message cache. Purges pages that include this page if the text was changed here. Every 100th edit, prune the recent changes table.

Deprecated
since 1.32 (soft), use DerivedPageDataUpdater::doUpdates instead.
Parameters
Revision | RevisionRecord$revisionRecordsince 1.35, can be a RevisionRecord object, and passing a Revision is hard deprecated
User$userUser object that did the revision
array$optionsArray of options, following indexes are used:
  • changed: bool, whether the revision changed the content (default true)
  • created: bool, whether the revision created the page (default false)
  • moved: bool, whether the page was moved (default false)
  • restored: bool, whether the page was undeleted (default false)
  • oldrevision: RevisionRecord object for the pre-update revision (default null) can also be a Revision object, but that is deprecated since 1.35
  • oldcountable: bool, null, or string 'no-change' (default null):
    • bool: whether the page was counted as an article before that revision, only used in changed is true and created is false
    • null: if created is false, don't update the article count; if created is true, do update the article count
    • 'no-change': don't update the article count, ever
  • causeAction: an arbitrary string identifying the reason for the update. See DataUpdate::getCauseAction(). (default 'edit-page')
  • causeAgent: name of the user who caused the update. See DataUpdate::getCauseAgent(). (string, defaults to the passed user)

◆ doPurge()

WikiPage::doPurge ( )

Perform the actions of a page purging.

Returns
bool
Note
In 1.28 (and only 1.28), this took a $flags parameter that controlled how much purging was done.

Reimplemented in WikiFilePage.

Definition at line 1314 of file WikiPage.php.

References NS_MEDIAWIKI.

◆ 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

Definition at line 3245 of file WikiPage.php.

References User\matchEditToken(), User\pingLimiter(), 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).
  • known-revision-output: a combined canonical ParserOutput for the revision, perhaps from some cache. The caller is responsible for ensuring that the ParserOutput indeed matched the $rev and $options. This mechanism is intended as a temporary stop-gap, for the time until caches have been changed to store RenderedRevision states instead of ParserOutput objects. (default: null) (since 1.33)
Since
1.32

◆ doUpdateRestrictions()

WikiPage::doUpdateRestrictions ( array $limit,
array $expiry,
& $cascade,
$reason,

int&$cascadeSet to false if cascading protection isn't allowed.
string$reason
User$userThe user updating the restrictions
string | string[] | null$tagsChange tags to add to the pages and protection log entries ($user should be able to add the specified tags before this is called)
Returns
