Constructor & Destructor Documentation

CategoryPager::__construct ( IContextSource  $context,
  $from,
LinkRenderer  $linkRenderer 
)
Parameters
IContextSource$context
string$from
LinkRenderer$linkRenderer

Member Function Documentation

◆ formatRow()

CategoryPager::formatRow (   $row)

Returns an HTML string representing the result row $row.

Rows will be concatenated and returned by getBody()

Parameters
array | stdClass$rowDatabase row
Returns
string

Reimplemented from IndexPager.

Definition at line 78 of file CategoryPager.php.

References $title, ContextSource\getLanguage(), IndexPager\getLinkRenderer(), ContextSource\msg(), and NS_CATEGORY.

◆ getBody()

CategoryPager::getBody ( )

Get the formatted result list.

Calls getStartBody(), formatRow() and getEndBody(), concatenates the results and returns them.

Returns
string

Reimplemented from IndexPager.

Definition at line 64 of file CategoryPager.php.

References LinkBatch\addObj(), and NS_CATEGORY.

◆ getDefaultQuery()

CategoryPager::getDefaultQuery ( )

Get an array of query parameters that should be put into self-links.

By default, all parameters passed in the URL are used, except for a short blacklist.

Returns
array Associative array

Reimplemented from IndexPager.

Definition at line 56 of file CategoryPager.php.

References IndexPager\$mDefaultQuery.

◆ getIndexField()

CategoryPager::getIndexField ( )

Returns the name of the index field.

If the pager supports multiple orders, it may return an array of 'querykey' => 'indexfield' pairs, so that a request with &order=querykey will use indexfield to sort. In this case, the first returned key is the default.

Needless to say, it's really not a good idea to use a non-unique index for this! That won't page right.

The pager may paginate on multiple fields in combination. If paginating on multiple fields, they should be unique in combination (e.g. when paginating on user and timestamp, rows may have the same user, rows may have the same timestamp, but rows should all have a different combination of user and timestamp).

Examples:

  • Always paginate on the user field: 'user'
  • Paginate on either the user or the timestamp field (default to user): [ 'name' => 'user', 'time' => 'timestamp', ]
  • Always paginate on the combination of user and timestamp: [ [ 'user', 'timestamp' ] ]
  • Paginate on the user then timestamp, or the timestamp then user: [ 'nametime' => [ 'user', 'timestamp' ], 'timename' => [ 'timestamp', 'user' ], ]
Returns
string|string[]|array[]

Reimplemented from IndexPager.

Definition at line 52 of file CategoryPager.php.

◆ getQueryInfo()

CategoryPager::getQueryInfo ( )

Provides all parameters needed for the main paged query.

It returns an associative array with the following elements: tables => Table(s) for passing to Database::select() fields => Field(s) for passing to Database::select(), may be * conds => WHERE conditions options => option array join_conds => JOIN conditions

Returns
array

Reimplemented from IndexPager.

Definition at line 44 of file CategoryPager.php.

◆ getStartForm()

CategoryPager::getStartForm (   $from)

Definition at line 87 of file CategoryPager.php.
