以laravel formRequests获取输入值

Question

这是我的FormRequest类

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use URL;
class CaseStudyUpdateRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
      $id = $this->request->get('cspid');
      dump($this);
      dump($id);
      $prev_url = URL::previous();
      $url_arr = explode('/', $prev_url);
      $data = $this->request->all();
      dump($data);
        $rules = [
            // 'post_title' => 'required|min:15|max:255|unique:case_study_posts,title,'.$id,
            'summary' => "required|array|min:1",
            'total_blocks' => "not_in:0",
            'category' => 'required',
            'specialities' => 'required',
        ];
        if($url_arr[4] === "edit-for-request") {
          // $rules['edit_comment'] = 'required';
                if(!empty($data)) {
                  $rules['edit_comment'] = 'required';
                    $totalBlocks = $data['total_blocks'];
                    foreach(range(1, $totalBlocks) as $i){
                        if(array_key_exists("description-$i", $data)) {
                          // $rules['edit_comment'] = 'required';
                            $rules["description-$i"] = 'required|min:15';
                        } elseif(array_key_exists("image-$i", $data) || array_key_exists("image_title-$i", $data) || array_key_exists("image_description-$i", $data)) {
                          // $rules['edit_comment'] = 'required';
                            $rules["image-$i"] = (array_key_exists("old-img-$i", $data) && !array_key_exists("image-$i", $data)?"":"required|mimes:jpeg,bmp,jpg,png|max:2048");
                            $rules["image_title-$i"] = "required_with:image-$i|required|min:5|max:30";
                            $rules["image_description-$i"] = "required_with:image_title-$i|required|min:15|max:120";
                        }
                    }
                }
        }

        return $rules;
    }

    public function messages() {
        return [
           'total_blocks'=> 'Please select text/images block to case studys',
        ];
    }

    /**
     * Get custom attributes for validator errors.
     *
     * @return array
     */
    public function attributes() {
        return [
            'post_title' => 'Case Study Title',
        ];
    }


}
?>

查看页面

在我的查看页面中，这>]

@section('scripts')
@parent
   {{ Html::script('vendor/jsvalidation/js/jsvalidation.js') }}
   {!! JsValidator::formRequest('App\Http\Requests\CaseStudyUpdateRequest', '#edit_post_form'); !!}  
   ....  
   ....   
Controller

在控制器中，我已经添加了

use App\Http\Requests\CaseStudyUpdateRequest;   
以及在调用的函数中

public function editCaseStudy(CaseStudyUpdateRequest $request) {
这里，我有图像块和描述块，例如image1，image2，image3，description1，description2等。我想验证这些字段，所以我需要在formRequest文件中获取那些输入值。但是当我打印dump($this->request->all());

时，它显示一个空数组

我如何在侧面formRequest中获得输入值？在此先感谢

这是我的FormRequest类

Answer 1

Illuminate\Foundation\Http\FormRequest类extends Illuminate\Http\Request类。因此，all()或the usual methods中的任何一个都将使您可以从GET或POST访问请求参数。

Answer 2

public function editCaseStudy(CaseStudyUpdateRequest $request) {
$image1=$request->image1;
$description1=$request->description1;
