Laravel unique validation on multiple columns

I have 2 columns in table servers.

I have columns ip and hostname.

I have validation:

'data.ip' => ['required', 'unique:servers,ip,'.$this->id]

This working only for column ip. But how to do that it would work and for column hostname?

I want validate data.ip with columns ip and hostname. Because can be duplicates in columns ip and hostname, when user write ip.

Answer

You can use Rule::unique to achieve your validation rule

$messages = [
    'data.ip.unique' => 'Given ip and hostname are not unique',
];

Validator::make($data, [
    'data.ip' => [
        'required',
        Rule::unique('servers')->where(function ($query) use($ip,$hostname) {
            return $query->where('ip', $ip)
            ->where('hostname', $hostname);
        }),
    ],
],
$messages
);
