yii 密码和确认密码是如何比较的

model层得属性与规则

public $password;public $qpassword;

[['username', 'password','qpassword'], 'required'],['password', 'validatePassword'],//compare比较得意思['qpassword','compare','compareAttribute'=>'password','message'=>'两次密码不一致'],

试图层

<?= $form->field($model, 'password')->passwordInput() ?><!--        确认密码--><?= $form->field($model, 'qpassword')->passwordInput() ?>
