Laravel 5.6问卷应用无法显示问题的答案字段

Hey there, let's figure out why your radio/checkbox options and answer fields aren't showing up in your survey form. From the snippet you shared, it looks like your Blade template gets cut off at the @if($quest... part—this incomplete conditional logic is almost certainly the root cause. Let's walk through the fixes step by step:

1. Complete the Question Type Conditional Rendering #

You need to explicitly check each question's type and render the corresponding form control. Here's how to flesh out your template properly, assuming your Question model has a type field (like radio, checkbox, or text) and an options relationship for choice-based questions:

{{$survey->title}}
{{$survey->description}}
Created by: {{$survey->user->name}}

{!! Form::open(array('action'=>array('AnswerController@store',$survey->id)))!!}

@forelse($survey->questions as $key=>$question)
    <div class="mb-4">
        <h5>Question {{$key+1}} - {{$question->title}}</h5>

        {{-- Render radio buttons for single-choice questions --}}
        @if($question->type === 'radio')
            @foreach($question->options as $option)
                <div class="form-check">
                    {!! Form::radio("answers[{$question->id}]", $option->id, false, ['class' => 'form-check-input']) !!}
                    {!! Form::label("answers[{$question->id}]", $option->text, ['class' => 'form-check-label']) !!}
                </div>
            @endforeach
        {{-- Render checkboxes for multiple-choice questions --}}
        @elseif($question->type === 'checkbox')
            @foreach($question->options as $option)
                <div class="form-check">
                    {!! Form::checkbox("answers[{$question->id}][]", $option->id, false, ['class' => 'form-check-input']) !!}
                    {!! Form::label("answers[{$question->id}][]", $option->text, ['class' => 'form-check-label']) !!}
                </div>
            @endforeach
        {{-- Render text input for open-ended questions --}}
        @elseif($question->type === 'text')
            {!! Form::text("answers[{$question->id}]", null, ['class' => 'form-control', 'placeholder' => 'Type your answer here']) !!}
        @endif
    </div>
@empty
    <p>This survey has no questions yet.</p>
@endforelse

{{-- Add a submit button (easy to forget!) --}}
<div class="mt-3">
    {!! Form::submit('Submit Your Answers', ['class' => 'btn btn-primary']) !!}
</div>

{!! Form::close() !!}

2. Verify Your Laravel Collective Form Setup #

Since you're using Form::open() and related syntax, make sure you've properly set up the Laravel Collective HTML package:

• Double-check that laravelcollective/html is in your composer.json (match the version to your Laravel release).
• Confirm Collective\Html\HtmlServiceProvider::class is listed in config/app.php under providers.
• Ensure the aliases are set in config/app.php:

  'aliases' => [
      // ...
      'Form' => Collective\Html\FormFacade::class,
      'Html' => Collective\Html\HtmlFacade::class,
  ]
  

3. Validate Your Model Relationships #

Make sure your survey, question, and option models have correct relationships:

// Survey.php
public function questions()
{
    return $this->hasMany(Question::class);
}

// Question.php
public function options()
{
    return $this->hasMany(Option::class); // Only if you have an Option model for choices
}

Also, when fetching the survey in your controller, eager-load the questions and their options to avoid N+1 queries:

$survey = Survey::with('questions.options')->findOrFail($surveyId);

4. Debug to Confirm Data is Loaded #

If you're still stuck, add temporary debug output to your template to check if data is being passed correctly:

{{-- Check if questions are loaded --}}
<pre>{{ print_r($survey->questions->toArray(), true) }}</pre>

{{-- Check question type and option count --}}
@foreach($survey->questions as $question)
    <p>Question Type: {{ $question->type }} | Options Count: {{ $question->options->count() }}</p>
@endforeach

This will tell you if your questions are missing type values, or if options aren't being loaded at all.
