yii\db\ActiveRecordInterface::link PHP Method

link() public method

The relationship is established by setting the foreign key value(s) in one record to be the corresponding primary key value(s) in the other record. The record with the foreign key will be saved into database without performing validation. If the relationship involves a junction table, a new row will be inserted into the junction table which contains the primary key values from both records. This method requires that the primary key value is not null.

public link ( string $name, static $model, array $extraColumns = [] )
$name	string	the case sensitive name of the relationship, e.g. `orders` for a relation defined via `getOrders()` method.
$model	static	the record to be linked with the current one.
$extraColumns	array	additional column values to be saved into the junction table. This parameter is only meaningful for a relationship involving a junction table (i.e., a relation set with [[ActiveQueryInterface::via()]]).
