getOldPrimaryKey() 공개 메소드

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 getOldPrimaryKey ( boolean $asArray = false ) : mixed
$asArray	boolean	whether to return the primary key value as an array. If true, the return value will be an array with column name as key and column value as value. If this is `false` (default), a scalar value will be returned for non-composite primary key.
리턴	mixed	the old primary key value. An array (column name => column value) is returned if the primary key is composite or `$asArray` is true. A string is returned otherwise (`null` will be returned if the key value is `null`).
