public update ( boolean $runValidation = true, array $attributeNames = null ) : integer | boolean |
|
$runValidation |
boolean |
whether to perform validation (calling [[\yii\base\Model::validate()|validate()]])
before saving the record. Defaults to `true`. If the validation fails, the record
will not be saved to the database and this method will return `false`. |
|
$attributeNames |
array |
list of attributes that need to be saved. Defaults to `null`,
meaning all attributes that are loaded from DB will be saved. |
| return |
integer | boolean |
the number of rows affected, or `false` if validation fails
or updating process is stopped for other reasons.
Note that it is possible that the number of rows affected is 0, even though the
update execution is successful. |
