Repeat Password does not work in Yii2

Question

I have written rules in the model as:

    public $password_repeat;

/**
 * @inheritdoc
 */
public function rules()
{
    return [
        ....
        ....  
        ['password', 'required'],
        ['password', 'string', 'min' => 6],
        ['password_repeat', 'compare', 'compareAttribute'=>'password', 'message'=>"Passwords don't match" ],
    ];
}

If I use different password in Password and Password Repeat field, it gives error. So, that's mean it works. But problem is that, it does not give any error if Password Repeat field is empty.

you need to mention required with repeat password like ['password_repeat', 'required'], – Marmara

Answer 1

Add a required tag for password_repeat as well. Shown below

return [
        ....  
        ['password', 'required'],
        ['password', 'string', 'min' => 6],
        ['password_repeat', 'required'],
        ['password_repeat', 'compare', 'compareAttribute'=>'password', 'message'=>"Passwords don't match" ],
    ];

We need not to use required in Yii.1.*. Can you tell me why we need to use in Yii2? – Catechetical

Yii and Yii2 have a lot of undocumented differences due to yii2 being built independently from scratch. This is just one of them. – Burt

Answer 2

Another approach is to set the $skipOnEmpty variable to false:

return [
....  
    ['password', 'required'],
    ['password', 'string', 'min' => 6],
    ['password_repeat', 'compare', 'compareAttribute'=>'password', 'skipOnEmpty' => false, 'message'=>"Passwords don't match"],
];

This has the benefit of allowing you to only make the repeat password field required if password has a value in it too.

brilliant - thank you. For anybody else trying this, you need to add a public variable to the model otherwise the form will declare an error. I.e.: public $password_repeat – Braiding
