Answer 1

Try transform your query to SQL to check what are you doing with database first

$additional_info = DB::table('additional_infos')->where('address',NULL)->orWhere('name', NULL)->orWhere('number')->toSql();
dd($additional_info);

Answer 2

You will never get null so that you can test it in if like this if( $additional_info) it will alawys evaluate to true, because it will always return a collection even if there is no elements that fulfil the conditions it will return a empty collection not null.

You have three choices :

• Use ->get() and add ->count() in the if statment if($additional_info->count())

• Replace ->get() by ->first() and leave if($additional_info)

• Replace ->get() by ->count() and if($additional_info > 0)

Try it using whereNull and orWhereNull like this :

public function test(Request $request){
    $additional_info = DB::table('additional_infos') 
                            ->whereNull('address')
                            ->orWhereNull('name')
                            ->orWhereNull('number')
                            ->get();
    //request input //ignore this part
    if( $additional_info->count())
        return redirect(url('/user/showupdate6/'.$id->id.'/edit6') );
    else{
    return redirect('/home');
}
