◆ 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$originalRevId,The ID of an original revision that the edit restores or repeats. The new revision is expected to have the exact same content as the given original revision. This is used with rollbacks and with dummy "null" revisions which are created to record things like page moves.
User | null$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 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.

Do standard deferred updates after page edit.

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.

Parameters
Revision$revision
User$userUser object that did the revision
array$optionsArray of options, following indexes are used:
  • changed: bool, whether the revision changed the content (default true)

  • 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 ( )

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

Reimplemented in WikiFilePage.

◆ 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$fromPName of the user whose edits to rollback.
string$summaryCustom summary. Set to default summary if empty.
string$tokenRollback token.
bool$botIf true, mark all reverted edits as bot.
array&$resultDetailsArray contains result-specific array of additional values 'alreadyrolled' : 'current' (rev) success : 'summary' (str), 'current' (rev), 'target' (rev)
User$userThe user performing the rollback
array | null$tagsChange tags to apply to the rollback Callers are responsible for permission checks (with ChangeTags::canAddTagsAccompanyingChange)
Returns
array Array of errors, each error formatted as [ messagekey, param1, param2, ... ]. On success, the array is empty. This array can also be passed to OutputPage::showPermissionsErrorPage().

Definition at line 3099 of file WikiPage.php.

References commitRollback(), 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)

◆ 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

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.

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