◆ resetNotificationTimestamp()

WatchedItemStore::resetNotificationTimestamp ( UserIdentity  $user,
  $title,
  $force = '',
  $oldid = 0 
)
Since
1.27
Parameters
UserIdentity$user
LinkTarget | PageIdentity$titledeprecated passing LinkTarget since 1.36
string$force
int$oldid
Returns

◆ setNotificationTimestampsForUser()

WatchedItemStore::setNotificationTimestampsForUser ( UserIdentity  $user,
  $timestamp,
array  $targets = [] 
)

Set the "last viewed" timestamps for certain titles on a user's watchlist.

If the $targets parameter is omitted or set to [], this method simply wraps resetAllNotificationTimestampsForUser(), and in that case you should instead call that method directly; support for omitting $targets is for backwards compatibility.

If $targets is omitted or set to [], timestamps will be updated for every title on the user's watchlist, and this will be done through a DeferredUpdate. If $targets is a non-empty array, only the specified titles will be updated, and this will be done immediately (not deferred).

Since
1.27
Parameters
UserIdentity$user
string | int$timestampValue to set the "last viewed" timestamp to (null to clear)
LinkTarget[]$targetsTitles to set the timestamp for; [] means the entire watchlist
Returns
bool

Implements WatchedItemStoreInterface.
