Detailed Description

Table-based display with a user-selectable sort order.

Constructor & Destructor Documentation

◆ __construct()

Member Function Documentation

◆ formatRow()

TablePager::formatRow (   $row)
Access:
protected
Parameters
stdClass$row
Returns
string HTML

Definition at line 190 of file TablePager.php.

References $s, Html\closeElement(), formatValue(), getCellAttrs(), getFieldNames(), getRowAttrs(), Html\openElement(), and Html\rawElement().

◆ formatValue()

TablePager::formatValue (   $name,
  $value 
)
abstract

Format a table cell.

The return value should be HTML, but use an empty string not &#160; for empty cells. Do not include the

and .

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

Access:
protected
Parameters
string$nameThe database field name
string$valueThe value retrieved from the database

Referenced by formatRow(), and getLimitDropdown().

◆ 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

Implements Pager.

Definition at line 72 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 86 of file TablePager.php.

References getModuleStyles().

◆ getCellAttrs()

TablePager::getCellAttrs (   $field,
  $value 
)

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

Access:
protected
Parameters
string$fieldThe column
string$valueThe cell contents
Returns
array Array of attr => value

protected
Returns

Returns
string

Definition at line 170 of file TablePager.php.

◆ getFieldNames()

TablePager::getFieldNames ( )
abstract

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(), getLimitDropdown(), and getStartBody().

◆ getFullOutput()

TablePager::getFullOutput ( )

Get the formatted result list, with navigation bars.

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

Since
1.24
Returns
ParserOutput
