Public Member Functions
	__construct (IConnectionProvider $dbProvider)

	execute ( $par)
	This is the actual workhorse.

	getQueryInfo ()
	Subclasses return an SQL query here, formatted as an array with the following keys: tables => Table(s) for passing to Database::select() fields => Field(s) for passing to Database::select(), may be * conds => WHERE conditions options => options join_conds => JOIN conditions.

	Should this query page only be updated offline on large wikis?

Member Function Documentation

◆ execute()

MediaWiki\Specials\SpecialUncategorizedImages::execute ( $par )

This is the actual workhorse.

It does everything needed to make a real, honest-to-gosh query page.

Stability: stable: to override

Parameters

string | null $par

Reimplemented from MediaWiki\SpecialPage\QueryPage.

References MediaWiki\SpecialPage\SpecialPage\addHelpLink().

◆ getGroupName()

MediaWiki\Specials\SpecialUncategorizedImages::getGroupName ( )

protected

Under which header this special page is listed in Special:SpecialPages See messages 'specialpages-group-*' for valid names This method defaults to group 'other'.

Stability: stable: to override

Returns: string

Since: 1.21

Reimplemented from MediaWiki\SpecialPage\SpecialPage.

Definition at line 88 of file SpecialUncategorizedImages.php.

◆ getOrderFields()

MediaWiki\Specials\SpecialUncategorizedImages::getOrderFields ( )

protected

Subclasses return an array of fields to order by here.

Don't append DESC to the field names, that'll be done automatically if sortDescending() returns true.

Stability: stable: to override

Returns: string[]

Since: 1.18

Reimplemented from MediaWiki\SpecialPage\QueryPage.

Definition at line 58 of file SpecialUncategorizedImages.php.

◆ getQueryInfo()

MediaWiki\Specials\SpecialUncategorizedImages::getQueryInfo ( )

Subclasses return an SQL query here, formatted as an array with the following keys: tables => Table(s) for passing to Database::select() fields => Field(s) for passing to Database::select(), may be * conds => WHERE conditions options => options join_conds => JOIN conditions.

Note that the query itself should return the following three columns: 'namespace', 'title', and 'value'. 'value' is used for sorting.

These may be stored in the querycache table for expensive queries, and that cached data will be returned sometimes, so the presence of extra fields can't be relied upon. The cached 'value' column will be an integer; non-numeric values are useful only for sorting the initial query (except if they're timestamps, see usesTimestamps()).

Don't include an ORDER or LIMIT clause, they will be added.

If this function is not overridden or returns something other than an array, getSQL() will be used instead. This is for backwards compatibility only and is strongly deprecated.

Stability: stable: to override

Returns: array

Since: 1.18

◆ isExpensive()

MediaWiki\Specials\SpecialUncategorizedImages::isExpensive ( )

Should this query page only be updated offline on large wikis?

If the query for this page is considered too expensive to run on-demand for large wikis (e.g. every time the special page is viewed), then implement this as returning true.

"Large wikis" are those that enable $wgMiserMode. The value of ::isExpensive() has no effect by default when $wgMiserMode is off.

It is expected that such large wikis, periodically run the UpdateSpecialPages maintenance script to update these query pages.

By enabling $wgDisableQueryPages, all query pages will be considered as expensive and updated offline only, even query pages that do not mark themselves as expensive.
