	getIndexField ()

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[] Stable to override

Constructor & Destructor Documentation

◆ __construct()

TablePager::__construct	(	IContextSource	$context = `null`,
		LinkRenderer	$linkRenderer = `null`

Stable to call.

Parameters

IContextSource \| null	$context

Member Function Documentation

◆ formatRow()

TablePager::formatRow ( $row )

Stable to override.

Parameters

stdClass $row

Returns: string HTML

Reimplemented from IndexPager.

Reimplemented in AllMessagesTablePager.

Definition at line 196 of file TablePager.php.

References $s, formatValue(), getCellAttrs(), getFieldNames(), and getRowAttrs().

◆ formatValue()

TablePager::formatValue	(	$name,
		$value
	)

abstract

Format a table cell.

The return value should be HTML, but use an empty string not   for empty cells. Do not include the

and .

The current result row is available as $this->mCurrentRow, in case you need more context.

Parameters

string	$name	The database field name
string	$value	The value retrieved from the database

Reimplemented in AllMessagesTablePager, ImageListPager, ProtectedPagesPager, and BlockListPager.

Referenced by formatRow().

◆ getBody()

TablePager::getBody ( )

final

Get the formatted result list.

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

Also adds the required styles to our OutputPage object (this means that if context wasn't passed to constructor or otherwise set up, you will get a pager with missing styles).

This method has been made 'final' in 1.24. There's no reason to override it, and if there exist any subclasses that do, the style loading hack is probably broken in them. Let's fail fast rather than mysteriously render things wrong.

Deprecated:: since 1.24, use getBodyOutput() or getFullOutput() instead

Returns: string

Reimplemented from IndexPager.

Definition at line 79 of file TablePager.php.

References getModuleStyles(), and ContextSource\getOutput().

◆ getBodyOutput()

TablePager::getBodyOutput ( )

Get the formatted result list.

Calls getBody() and getModuleStyles() and builds a ParserOutput object. (This is a bit hacky but works well.)

Since: 1.24

Returns: ParserOutput

Definition at line 93 of file TablePager.php.

References getModuleStyles(), and ParserOutput\setText().

◆ getCellAttrs()

TablePager::getCellAttrs	(	$field,
		$value
	)

protected

Get any extra attributes to be applied to the given cell.

Don't take this as an excuse to hardcode styles; use classes and CSS instead. Row context is available in $this->mCurrentRow

Stable to override

Parameters

string	$field	The column
string	$value	The cell contents

Returns: array Array of attr => value

Reimplemented in AllMessagesTablePager.

◆ getCurrentRow()

TablePager::getCurrentRow ( )

protected

Returns: stdClass

Definition at line 250 of file TablePager.php.

References $mCurrentRow.

◆ getDefaultSort()

TablePager::getDefaultSort ( )

abstract

The database field name used as a default sort order.

Note that this field will only be sorted on if isFieldSortable returns true for this field. If not (e.g. paginating on multiple columns), this should return empty string, and getIndexField should be overridden.

Returns: string

Reimplemented in AllMessagesTablePager, BlockListPager, ImageListPager, and ProtectedPagesPager.

abstractprotected

An array mapping database field names to a textual description of the field name, for use in the table header.

The description should be plain text, it will be HTML-escaped later.

Returns: array

Referenced by __construct(), formatRow(), getEmptyBody(), and getStartBody().

◆ getFullOutput()

TablePager::getFullOutput ( )

Get the formatted result list, with navigation bars.
