How can I make such validation in YII2?

Question

How can I make such validation in YII2?

There are two attributes in the model "user_id" and "invite_id"
let's say equal to 1 and 2
It is necessary to check whether such a pair is 1 and 2, as well as whether there is a pair of 2 and 1
How to implement it? Normal unique validator will not help you to write your own?

ExistValidator not?

The same as unique, the issue was in the record. Already suggested about the filter - Henderson_Beat commented on July 8th 19 at 16:15

Solution

Maybe something like this,

[
 ['user_id', 'invite_id'],
'unique',
 'targetAttribute' => ['user_id', 'invite_id'],
 'filter' => [
'or',
 ['user_id' => $this->invite_id],
 ['invite_id' => $this->user_id],
]
],

haven't checked how it works, found at the docks filter. thank you. Have done so:

[['user_id', 'invite_id'], 'unique','targetAttribute' => ['user_id', 'invite_id'], 'filter'=>function($query){return $query->orWhere(['and',['user_id'=>$this->invite_id], ['invite_id'=>$this->user_id]]);}],
