In this example we will see laravel 8 eloquent orWhereHas() condition. In previous example we will learn about laravel 8 whereHas() condition. So, I will give you simple example of how to use orWherehas() condition with laravel eloquent relationship. you can also use with laravel 6, laravel 7 and laravel 8 version.

    For orWhereHas() condition in laravel 8 we are using three tables like users, country and state and in users tabel add country_id and state_id relationship. And also in this use whereHas() with orWhereHas() condition in laravel 8.

    So, let's see laravel 8 orWhereHas() realationship.

    Laravel eloquent whereHas() method works basically the same as has() but it just allows you to specify additional filters for the related model to check. 

public function index()
{
    $name = 'California';
    $users = User::with('country','state')
                    ->whereHas('country', function ($query) use($name){
                        $query->where('name', 'like', '%'.$name.'%');
                    })
                    ->orWhereHas('state', function ($query) use($name){
                        $query->where('name', 'like', '%'.$name.'%');
                    })
                    ->get()
                    ->toArray();
}

    ]; 
  
    public function country()
    {
        return $this->belongsTo(Country::class);
