Member Function Documentation

◆ execute()

MIMEsearchPage::execute ( $par )

This is the actual workhorse.

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

Parameters

string $par

Reimplemented from QueryPage.

Definition at line 131 of file SpecialMIMEsearch.php.

References getPageHeader(), SpecialPage\getRequest(), list, SpecialPage\outputHeader(), SpecialPage\setHeaders(), and File\splitMime().

◆ formatResult()

MIMEsearchPage::formatResult	(	$skin,
		$result
	)

Parameters

Skin	$skin
object	$result	Result row

Returns: string

◆ getGroupName()

MIMEsearchPage::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'.

Returns: string

Since: 1.21

Reimplemented from SpecialPage.

Definition at line 202 of file SpecialMIMEsearch.php.

◆ getOrderFields()

MIMEsearchPage::getOrderFields ( )

The index is on (img_media_type, img_major_mime, img_minor_mime) which unfortunately doesn't have img_name at the end for sorting.

So tell db to sort it however it wishes (Its not super important that this report gives results in a logical order). As an aditional note, mysql seems to by default order things by img_name ASC, which is what we ideally want, so everything works out fine anyhow.

Returns: array

Reimplemented from QueryPage.

Definition at line 104 of file SpecialMIMEsearch.php.

◆ getPageHeader()

MIMEsearchPage::getPageHeader ( )

Generate and output the form.

Reimplemented from QueryPage.

Definition at line 111 of file SpecialMIMEsearch.php.

References $mime, HTMLForm\factory(), SpecialPage\getContext(), and SpecialPage\getPageTitle().

Referenced by execute().

◆ getQueryInfo()

MIMEsearchPage::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

◆ isCacheable()

MIMEsearchPage::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.

Returns: bool

Since: 1.18

Reimplemented from QueryPage.

Definition at line 45 of file SpecialMIMEsearch.php.

◆ isExpensive()

MIMEsearchPage::isExpensive ( )

Is this query expensive (for some definition of expensive)? Then we don't let it run in miser mode.

$wgDisableQueryPages causes all query pages to be declared expensive. Some query pages are always expensive.

Returns: bool

Reimplemented from QueryPage.

Definition at line 37 of file SpecialMIMEsearch.php.

◆ isSyndicated()

MIMEsearchPage::isSyndicated ( )

Sometime we don't want to build rss / atom feeds.

They will be encoded and added to the paging links (prev/next/lengths).

Returns: array
