Laravel：如何在同一控制器中将变量从一个函数传递给来自Ajax调用的另一个函数

Question

I am new to laravel facing issue to pass variable from one function to another function i want to pass getidvalue variable from questionquiz5 to previousbtn function?? here is my code

public  function questionquiz5(Request $request){
  static $startscore=0;
  static $getscore;
  static $level;
  $var = "hi";

  $getidvalue = Input::get('getid');
  $getanswervalue = Input::get('getanswer');



  $dbscore = \DB::table('5question')->select('question_id','correct_answer','question_marks','question_level')->where('question_id','=',$getidvalue)->get();

  //// some code...........


  Session::push('getscoresession',$getscore);
  Session::push('level',$level);


  $getsession = [  'qid' => $getidvalue,  'answer' => $getanswervalue];

  Session::push('answer', $getsession);

  return response()->json(['qid'=>$getidvalue,'answer'=>$getanswervalue]);   

  return $this->previousbtn( $getidvalue);
  return $this->previousbtn( $getanswervalue);
}     


**previousbtn function:**


public function previousbtn(Request $request, $getidvalue)
{
  $prevbtnvalue = Input::get('page');  
  $getcompid = $this->getidvalue;
  echo "$getcompid";     
}

the error:

getting error : Type error: Too few arguments to function App\\Http\\Controllers\\scorecontroller::previousbtn(), 1 passed and exactly 2 expected

Answer 1

Like the error indicates, you are passing too few arugments.

return $this->previousbtn( $getidvalue);

Should be

return $this->previousbtn($request, $getidvalue);

Or if the request object is not used in the previousbtn method you can remove it from the arguments.
