PHP Piwik_DataTable::getSortedByColumnName方法代码示例

 /**
  * This functions reads the customization values for the DataTable and returns an array (name,value) to be printed in Javascript.
  * This array defines things such as:
  * - name of the module & action to call to request data for this table
  * - optional filters information, eg. filter_limit and filter_offset
  * - etc.
  *
  * The values are loaded:
  * - from the generic filters that are applied by default @see Piwik_API_DataTableGenericFilter.php::getGenericFiltersInformation()
  * - from the values already available in the GET array
  * - from the values set using methods from this class (eg. setSearchPattern(), setLimit(), etc.)
  *
  * @return array eg. array('show_offset_information' => 0, 'show_...
