Detailed Description

Special:LinkSearch to search the external-links table.

Constructor & Destructor Documentation

LinkSearchPage::__construct ( $ name = 'LinkSearch' )

Definition at line 37 of file SpecialLinkSearch.php.

Member Function Documentation

LinkSearchPage::doQuery	(	$	offset = `false`,
		$	limit = `false`
	)

Override to check query validity.

Reimplemented from QueryPage.

Definition at line 189 of file SpecialLinkSearch.php.

References QueryPage\$limit, QueryPage\$offset, SpecialPage\getOutput(), and mungeQuery().

Here is the call graph for this function:

LinkSearchPage::execute ( $ par )

This is the actual workhorse.

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

Reimplemented from QueryPage.

Definition at line 45 of file SpecialLinkSearch.php.

Here is the call graph for this function:

LinkSearchPage::formatResult	(	$	skin,
		$	result
	)

Formats the results of the query for display.

The skin is the current skin; you can use it for making links. The result is a single row of result data. You should be able to grab SQL results off of it. If the function returns false, the line output will be skipped.

Parameters:

$skin	Skin
$result	object Result row

Returns:: mixed String or false to skip

Parameters:

$skin	Skin object
$result	Object: database row

Here is the call graph for this function:

LinkSearchPage::getOrderFields ( )

Override to squash the ORDER BY.

We do a truncated index search, so the optimizer won't trust it as good enough for optimizing sort. The implicit ordering from the scan will usually do well enough for our needs.

Reimplemented from QueryPage.

Definition at line 207 of file SpecialLinkSearch.php.

LinkSearchPage::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.

Returns:: array

Since:: 1.18

Here is the call graph for this function:

LinkSearchPage::isCacheable ( )

Is the output of this query cacheable? Non-cacheable expensive pages will be disabled in miser mode and will not have their results written to the querycache table.
