在 laravel formRequests 中获取输入值

Question

这是我的 FormRequest class

<?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

在我的视图页面中，我有这个，

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

控制器

在 Controller 中，我添加了

use App\Http\Requests\CaseStudyUpdateRequest;

在被调用的函数中

public function editCaseStudy(CaseStudyUpdateRequest $request) {

在这里，我有图像块和描述块，比如图像 1、图像 2、图像 3、描述 1、描述 2 等。我想验证这些字段，所以我需要在 formRequest 文件中获取这些输入值。但是当我打印 dump($this->request->all());

时它显示一个空数组

如何在端 formRequest 中获取输入值？提前致谢

Answer 1

Illuminate\Foundation\Http\FormRequest class extends the Illuminate\Http\Request class. So all() or any of the usual methods 将允许您从 GET 或 POST.

访问请求参数

例如而不是这个：

$id = $this->request->get('cspid');

使用其中之一：

$id = $this->cspid;
$id = $this->get("cspid");

Answer 2

在表单请求class中，rules()函数：

$this->route()->parameter('myrouteparam')

在 laravel formRequests 中获取输入值
