Why don't you use Eloquent ?

In this case you could have something like this

$user = User::with('interests')->find($userId);

foreach($user->interests as $interest) {
	dd($interest->field->name, $interest->value->label);
}

To achieve this you should create a model UserInterest (pointing to the user_interests table) and add the field and value relationship like this (the $with attribute will eager load relationship each time you access the model)

Class UserInterest extends Model {
   protected $with = ['field', 'value'];

   function value() {
      return $this->belonsgTo(Value::class);
   }

   function field() {
      return $this->belongsTo(Field::class);
   }
}

and then add the interest method to the User model

function interests() {
   return $this->hasMany(UserInterest::class);
}

It's hard to do it without coding it but it should be working somehow

This works, but I just have one small problem now. When I dd($interest->field->name, $interest->value->label); in foreach I get only "genders" and "men" but I don't get "looking_for" and "Relationship" in this case. I want to be able to print both cases. Can you help?

With just $interest I get App\UserInterest {#1702 ▼ with information of just name "genders" and value "Men", but there is no looking_for and Relationship

Also when I dump $user->interests I get correct data. Illuminate\Database\Eloquent\Collection {#1672 ▼ #items: array:2 [▼ 0 => App\UserInterest {#1702 ▶} 1 => App\UserInterest {#1701 ▶} ] }

Where 0 i gender, men and 1 is looking for, relationship. But I can't print both values in blade.
