1 select.inc public SelectQueryExtender::addMetaData($key, $object)

Adds additional metadata to the query.

Often, a query may need to provide additional contextual data to alter hooks. Alter hooks may then use that information to decide if and how to take action.


$key: The unique identifier for this piece of metadata. Must be a string that follows the same rules as any other PHP identifier.

$object: The additional data to add to the query. May be any valid PHP variable.

Return value

QueryAlterableInterface: The called object.

Overrides QueryAlterableInterface::addMetaData
