Member Function Documentation

◆ getCellHtml()

MostimagesPage::getCellHtml (   $row)

Get additional HTML to be shown in a results' cell.

Parameters
object$rowResult row
Returns
string

Reimplemented from ImageQueryPage.

Definition at line 60 of file SpecialMostimages.php.

References SpecialPage\msg().

◆ getGroupName()

MostimagesPage::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 64 of file SpecialMostimages.php.

◆ getQueryInfo()

MostimagesPage::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

Reimplemented from QueryPage.

Definition at line 45 of file SpecialMostimages.php.

References array(), and NS_FILE.

◆ isExpensive()

MostimagesPage::isExpensive ( )

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

Returns
bool
