Laravel filter by multiple parameters?

Question

Laravel

tell me how to implement a user filter by 10 parameters?
I try like this

$gender = 0;
if (Auth::user()->attributes->gender == 1){
    $gender = 2; //Выводим деушек , если текущий пользователь парень
}
if (Auth::user()->attributes->gender == 2){
    $gender = 1; //Выводим парней , если текущий пользователь девушка
}

$users = User::filter($request->all(),$gender)
        ->orderBy('users.id','asc')->get();

but nothing works

public function scopeFilter($query,$request,$gender)
    {
        $query->leftJoin('user_attributes','user_attributes.user_id',
             '=','users.id');

        $query->select('users.id','users.slug','users.name',
            'user_attributes.fullname','user_attributes.age',
            'user_attributes.avatar',
            'user_attributes.city');
        $query->where('user_attributes.gender','=', $gender);
        return $query;
}

Answer 1

Well, for starters, I would advise you to look at what request you get as a result. If an error is returned, you can reset it here as well.

Answer 2

$gender = 0; 
if (Auth::user()->attributes->gender == 1){
    $gender = 2; 
}
else if (Auth::user()->attributes->gender == 2) { // Тут у вас ошибка
    $gender = 1;
}

Answer 3

Is the user's gender filled? dd($gender) returns what? Why request in an osprey? Or is it a truncated code? For debug here you need to post the exact one. Why not through relationships done? I would stuff all the specified fields from the attributes into users and it is possible without an attribute table at all. Well, or whereHas if through relationships, but you definitely need to store gender not in attributes. FullName can be collected in the model

public function getFullNameAttribute()
{
    return $this->name.' '.$this->lastname;
}

and receive via
$user->FullName
