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
Returns
int

Reimplemented from QueryPage.

Definition at line 103 of file SpecialMIMEsearch.php.

◆ formatResult()

MIMEsearchPage::formatResult (   $skin,
  $result 
)
Parameters
Skin$skin
object$resultResult 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 189 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.

Reimplemented from QueryPage.

Definition at line 99 of file SpecialMIMEsearch.php.

References array().

◆ 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

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.

Returns
bool

Reimplemented from QueryPage.

◆ isValidType()

static MIMEsearchPage::isValidType (   $type)
staticprotected
Parameters
$typestring
Returns
bool

References $type, and array().

◆ linkParameters()

MIMEsearchPage::linkParameters ( )

If using extra form wheely-dealies, return a set of parameters here as an associative array.

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

Returns
