问题描述
我是laravel的新手，我正在laravel进行测验，我遇到了这个问题
I am new in laravel, I am making quiz application in laravel, I got this issue
@include('inc.header')
<br>
<div class="container">
<div class="row">
<form method="POST" action="{{ url('/store-quiz') }}" class="" id="quiz_module">
{{ csrf_field() }}
@foreach($questions as $question)
@if($id == $question->category_id)
<legend> Quiz Of {{ $question->category->title }}</legend>
<div class="jumbotron">
<input type="hidden" name="user_id" value="{{ auth()->user()->id }}">
<input type="hidden" name="category_id" value="{{ $question->category_id }}">
<input type="hidden" name="question_id" value="{{ $question->id }}">
<h4>
Question {{ $question->id }}
</h4>
<h3>
{{ $question->question }}
</h3><brx`>
<h5>
 <input type="radio" name="user_answer" class="form-check-input" value="{{ $question->option_a }}">{{ $question->option_a }}<br>
 <input type="radio" name="user_answer" class="form-check-input" value="{{ $question->option_b }}">{{ $question->option_b }}<br>
 <input type="radio" name="user_answer" class="form-check-input" value="{{ $question->option_c }}">{{ $question->option_c }}<br>
 <input type="radio" name="user_answer" class="form-check-input" value="{{ $question->option_d }}">{{ $question->option_d }}<br>
</h5>
</div>
@endif
@endforeach
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
</div>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/1000hz-bootstrap-validator/0.11.5/validator.min.js"></script>
<script type="text/javascript">
$("#quiz_module").click(function(){
var url = $(this).attr("action");
$.ajax({
url: "/store-answer",
type:"POST",
data: $('form').serialize(),
}); //end of ajax
});
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf_token"]').attr('content')
}
});
</script>
@include('inc.footer')
您可以在此处看到我的输出 https://prnt.sc/p4esh1
You can see my output here https://prnt.sc/p4esh1
这里从数据库中获取所有记录.单击任何单选按钮以获取答案，它将在数据库中存储user_id，category_id，question_id和答案.
Here I am getting all records from database.For answer when I click on any radio button, It will store user_id, category_id, question_id and answer in database.
但是问题在于，每次获取最后一个问题的问题ID时都会出现.
But the problem is that everytime it take last question's question id.
我想存储单个问题的ID，例如如果我选择第二个问题的答案，则在数据库中存储第二个问题的问题ID，与第三个问题相同. 但是这里每次都节省3.
I want to store individual question id, like if I select 2nd question's answer then in database 2nd question's question id save, same for 3rd question. But here everytime it saves 3.
我该如何解决? 请指导我，谢谢！
How can I resolve this?? Please guide me, Thank You!
在我的控制器中，我的代码如下所示
In My controller I code like below
public function storeAnswer(Request $request)
{
$create = Quiz::create($request->all());
return redirect('/home');
}
推荐答案
我认为您必须在提交"按钮上一起提交所有答案.请对您的代码进行以下更改.请注意: 1)形式在foreach之外 2)提交按钮应放入表单标签中. 3)将每个元素的名称转换为表格.
I think you have to submit all answer together on submit button. please make below changes into your code. please note that: 1) form is outside of foreach 2) submit button should be into form tag. 3) name of each element into form.
<form method="POST" action="{{ url('/store-answer') }}" class="crud-submit" id="quiz_module">
@foreach($questions as $i => $question)
<?php
print_r($question);
?>
<legend> {{$i}} Quiz Of {{ $question['category']['title'] }}</legend>
<div class="jumbotron">
<input type="hidden" name="user_id" value="1">
<input type="hidden" name="que_module[{{$i}}]['category_id']" value="{{ $question['category_id'] }}">
<input type="hidden" name="que_module[{{$i}}]['question_id']" value="{{ $question['id'] }}">
<h4>
Question {{ $question['id'] }}
</h4>
<h3>
{{ $question['question'] }}
</h3><br>
<h5>
 <input type="radio" name="que_module[{{$i}}]['answer']" class="form-check-input" value="{{ $question['option_a'] }}">{{ $question['option_a'] }}<br>
 <input type="radio" name="que_module[{{$i}}]['answer']" class="form-check-input" value="{{ $question['option_b'] }}">{{ $question['option_b'] }}<br>
 <input type="radio" name="que_module[{{$i}}]['answer']" class="form-check-input" value="{{ $question['option_c'] }}">{{ $question['option_c'] }}<br>
 <input type="radio" name="que_module[{{$i}}]['answer']" class="form-check-input" value="{{ $question['option_d'] }}">{{ $question['option_d'] }}<br>
</h5>
</div>
@endforeach
<button type="submit" class="btn btn-primary">Submit</button>
</form>
您还必须按照以下方式更改为jquery.
you have to changed into jquery also as below.
$("#quiz_module").submit(function(e)
{
e.preventDefault();
$.ajax({
type: 'POST',
dataType: 'json',
url: '/store-answer',
data: $("#quiz_module").serialize(),
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
});
});
您已将所有数据放入控制器，如下所示.
you have get all data into controller as below.
function storeAnswer(Request $req){
print_r($req->all());
}
