Question

我想将数据从AJAX传递到我的Laravel Controller。但数据没有通过。这是我的控制器和刀片代码。数据没有从刀片传递到Ajax。我的控制器没有收到数据。

控制器文件：

public function store(Request $request)
{
    $new_name='';
    $new_email='';
    $new_clg='';
    $new_university='';
    $new_stream='';


   $user = DB::table('users')->select('name', 'email', 'College', 'stream','university')->get();
  /* print_r($request->jsonString);*/
  foreach($user as $d){
        $new_name= $d->name;
        $new_email=$d->email;
        $new_clg=$d->College;
        $new_university=$d->university;
         $new_stream=$d->stream;
  }

    $name1 = explode(",", $request->jsonString);/*
    $name2 = explode('["', $name1);
    $name3 = explode('"', $name1);*/
    $temp = explode('"',$request->jsonString);
   // $temp1  =   explode('"',$temp);
    print_r($temp);
    $Q1=$temp[1];
    $Q2=$temp[3];
    $Q3=$temp[5];
    $Q4=$temp[7];
    $Q5=$temp[9];
    $Q6=$temp[11];
    $Q7=$temp[13];
    $Q8=$temp[15];
    $Q9=$temp[17];
    $Q10=$temp[19];
    $Q11=$temp[21];
    $Q12=$temp[23];
    $Q13=$temp[25];
    $Q14=$temp[27];
    $Q15=$temp[29];
    $Q16=$temp[31];        // $this->validate(request(),[

    //  $user =
    //  //'answers.*'=> 'required|' 

    // ]);  ["0.3s"]
   // $result = 0;

   //  $test = Test::create([
   //      'user_id' => Auth::id(),
   //      'result'  => $result,
   //  ]);

     $report = master::create([
            'user_id' => Auth::id(),
             'user_name' => $new_name,
            'user_email' => $new_email,
            'Stream' => $new_stream,
            'University' => $new_university,
            'College_Institution' => $new_clg,
            'Q1' => $Q1,
            'Q2' => $Q2,
            'Q3' => $Q3,
            'Q4' => $Q4,
            'Q5' => $Q5,
            'Q6' => $Q6,
            'Q7' => $Q7,
            'Q8' => $Q8,
            'Q9' => $Q9,
            'Q10' => $Q10,
            'Q11' => $Q11,
            'Q12' => $Q12,
            'Q13' => $Q13,
            'Q14' => $Q14,
            'Q15' => $Q15,
            'Q16' => $Q16
            ]);
       $report->save();
    foreach ($request->input('questions', []) as $key => $question) {
        $status = 0;

        if ($request->input('options.'.$question) != null
            && QuestionsOption::find($request->input('options.'.$question))
        ) {

            $status = 1;
            $result++;
        }
        else {

           return redirect()->back();
        }

        // TestAnswer::create([
        //     'user_id'     => Auth::id(),
        //     'test_id'     => $test->id,
        //     'question_id' => $question,
        //     'option_id'   => $request->input('answers.'.$question),
        //     'correct'     => $status,
        // ]);
    }
   //  DB::insert('insert into master values(?)',[$report]);
    //$report->insert()

   // $test->update(['result' => $result]);

  //  return redirect()->route('results.show', [$test->id]);
}

刀片文件：

function endQuiz(){
       // $('#explanation').empty();

       // console.log(score);
        $('#question').empty();
        $('#choice-block').empty();
        $('#submitbutton').remove();
         $(document.createElement('h2')).css({'text-align':'center', 'font-size':'4em'}).text('Congratulation!! You have successfully completed your test.').insertAfter('#question');

        var jsonString =JSON.stringify(score);
        /*alert(jsonString);*/
         $.ajax({
        type: "post",
        url: "/scores",
        dataType: "JSON",
        data:{'jsonString':jsonString},
        success: function(data){
               alert("Test Completed")
             // window.location.href = "{{('/home')}}";
        },
        error: function(data){
             alert("Test Completed")
             // window.location.href = "{{('/home')}}";
        }
    });
    }

请帮我解决这个问题。

在Blade文件中，你需要有类似的东西

function endQuiz() {
// Do your stuff here
var jsonString = JSON.stringify(score);

// Make an AJAX request         
$.ajax({             
type: 'post',             
url: '{{ URL::action (‘SomeController@store’) }}',             
data: jsonString,       
success: function(result) {             
   if(result.success) {                 
      console.log("Success");             
   }             
},             
error: function() {                 
   console.log(error);             
   }         
});     
}

在Controller中，您应该返回一个json响应，它可以是数组的组合。像这样的例子

return response(array('success' => true));

在Laravel中将数据从Ajax传递到Controller
