Validating multiple attributes within a inline validator in Yii 2

Question

I'm aware you can validate a single attribute using an inline validator such as:

['country', 'validateCountry']

public function validateCountry($attribute, $params)
{
    if (!in_array($this->$attribute, ['USA', 'Web'])) {
        $this->addError($attribute, 'The country must be either "USA" or "Web".');
    }
}

But how do I go about passing in multiple attributes into the validator? ...or should I just reference them via $this within the validator?

I think you do not understand what is happening here. The array ['country', 'validateCountry'] basically states that validateCountry is applied to country, if you want to apply the validator function to other attribute just add ['secondAttribute', 'validateCountry'] and the validator would automatically apply the function for both country and secondAttribute — user2862309

@Mr.Meshuggah Yes, I understand how it works. It works on the country attribute which is $this->country. However I need to make a custom validator function to check the username and email attributes against the database; I would prefer to pass them BOTH to a single validator rather than separately so I can just run the single query. — Brett

Instead of accessing the extra fields directly e.g using $this->email you could pass the additional attributes as a field in params, like how the compareValidator works i.e

['username', 'customValidator', 'params' => ['extraFields' => 'email']]


public function customValidator($attribute, $params) {
    //access extrafields using $this->{$params['extraFields']}
}

That worked, but I had to do this: ['username', 'customValidator', 'params' => ['email' => 'email']]

In Yii2, you should write it like below:

['username', 'customValidator', 'params' => ['extraFields' => 'email']]

@L.Antonelli notice the update time. I answered for Yii2 in 2015, and he edited the answer in 2016. It's he who copied my answer.
