Member Function Documentation

◆ doQuery()

LogPager::doQuery ( )

Do the query, using information from the object context.

This function has been kept minimal to make it overridable if necessary, to allow for result sets formed from multiple DB queries.

Stability: stable
to override

Reimplemented from IndexPager.

Definition at line 503 of file LogPager.php.

◆ formatRow()

LogPager::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 452 of file LogPager.php.

◆ getAction()

LogPager::getAction ( )

Definition at line 499 of file LogPager.php.

◆ getDay()

LogPager::getDay ( )

Definition at line 491 of file LogPager.php.

References ReverseChronologicalPager\$mDay.

◆ getDefaultQuery()

LogPager::getDefaultQuery ( )

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

By default, all parameters passed in the URL are used, apart from a few exceptions.

Stability: stable
to override
Returns
array Associative array

Reimplemented from IndexPager.

◆ getFilterParams()

LogPager::getFilterParams ( )

Definition at line 146 of file LogPager.php.

References $type, ContextSource\getConfig(), and ContextSource\getRequest().

Referenced by getQueryInfo().

◆ getIndexField()

LogPager::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[]
