db\BaseActiveRecord getOldPrimaryKey()

getOldPrimaryKey() public method

Returns the old primary key value(s).

This refers to the primary key value that is populated into the record after executing a find method (e.g. find(), findOne()). The value remains unchanged even if the primary key attribute is manually assigned with a different value.

public mixed getOldPrimaryKey ( $asArray = false )
$asArray	boolean	Whether to return the primary key value as an array. If `true`, the return value will be an array with column name as key and column value as value. If this is `false` (default), a scalar value will be returned for non-composite primary key.
return	mixed	The old primary key value. An array (column name => column value) is returned if the primary key is composite or `$asArray` is `true`. A string is returned otherwise (null will be returned if the key value is null).
throws	yii\db\Exception	if the AR model does not have a primary key
