上一节代码中已经实现 下面代码中的validate内部配置就是：
1 public function store(Request $request)
2 {
3 //
4 $data = $request->validate([
5 'title' => 'required|min:8',
6 'content' => 'required|min:8',
7 ]);
8
9 $data['user_id'] = auth()->user()->id;
10
11 $question = Question::create($data);
12
13 return redirect()->route('questions.show', $question);
14 }
注：validate方法详见：表单验证
且 create.blade.php中也已经使用
1 <p class="text text-danger"> @error('title') {{ $message }} @enderror </p>
2
3 <p class="text text-danger"> @error('content') {{ $message }} @enderror </p>
4
实现错误提示。不过差一个错误后，留存用户上一次填写的内容，输出给用户用于再次修改，
然后代码如下：
1 @extends('layouts.app')
2 @section('content')
3 @include('vendor.ueditor.assets')
4 <div class="container">
5 <div class="row">
6 <div class="col-md-8 col-md-offset-2">
7 <div class="card">
8 <div class="card-header">
9 发布问题
10 </div>
11 <div class="card-body">
12 <form action="{{ route('questions.store') }}" method="post">
13 {{--注意要有csrftoken--}}
14 @csrf
15 <div class="form-group">
16 <label for="title">标题</label>
17 <input type="text" name="title" class="form-control" placeholder="标题" id="title"
18 value="{{ old('title') }}">
19 <p class="text text-danger"> @error('title') {{ $message }} @enderror </p>
20 </div>
21 <!-- 编辑器容器 -->
22 <script id="container" name="content" type="text/plain">{!! old('content') !!}</script>
23 <p class="text text-danger"> @error('content') {{ $message }} @enderror </p>
24 <!--发布按钮-->
25 <button type="submit" class="btn btn-primary mt-2 float-md-right">发布问题</button>
26 </form>
27 </div>
28 </div>
29 </div>
30 </div>
31 </div>
32
33 <!-- 实例化编辑器 -->
34 <script type="text/javascript">
35 var ue = UE.getEditor('container');
36 ue.ready(function () {
37 ue.execCommand('serverparam', '_token', '{{ csrf_token() }}'); // 设置 CSRF token.
38 });
39 </script>
40
41 @endsection
当然如果验证要求比较多，可以执行：
1 php artisan make:request QuestionStoreRequest
然后将QuestionController.php文件中验证部分注释掉，我们将使用依赖注入QuestionStoreRequest实例的方式处理请求验证，
1 <?php
2
3 namespace App\Http\Controllers;
4
5 use App\Http\Requests\QuestionStoreRequest;
6 use App\Models\Question;
7 use App\User;
8 use Illuminate\Http\Request;
9
10 class QuestionController extends Controller
11 {
12 public function __construct()
13 {
14 $this->middleware('auth', ['except' => ['index', 'show']]);//非注册用户只能查看不能编辑添加更改删除
15 }
16
17 /**
18 * Display a listing of the resource.
19 *
20 * @return \Illuminate\Http\Response
21 */
22 public function index()
23 {
24 //
25
26 }
27
28
29 /**
30 * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
31 */
32 public function create()
33 {
34 //
35 return view('questions.create');
36 }
37
38
39 /**
40 * @param QuestionStoreRequest $request
41 * @return \Illuminate\Http\RedirectResponse
42 */
43 public function store(QuestionStoreRequest $request)//依赖注入QuestionStoreRequest实例
44 {
45 //
46 // $data = $request->validate([
47 // 'title' => 'required|min:8',
48 // 'content' => 'required|min:28',
49 // ]);
50 $data = $request->all();
51 $data['user_id'] = auth()->user()->id;
52
53 $question = Question::create($data);
54
55 return redirect()->route('questions.show', $question);
56 }
57
58
59 /**
60 * @param Question $question
61 * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
62 */
63 public function show(Question $question)
64 {
65 //
66 return view('questions.show', compact('question'));
67 }
68
69 /**
70 * Show the form for editing the specified resource.
71 *
72 * @param int $id
73 * @return \Illuminate\Http\Response
74 */
75 public function edit($id)
76 {
77 //
78 }
79
80 /**
81 * Update the specified resource in storage.
82 *
83 * @param \Illuminate\Http\Request $request
84 * @param int $id
85 * @return \Illuminate\Http\Response
86 */
87 public function update(Request $request, $id)
88 {
89 //
90 }
91
92 /**
93 * Remove the specified resource from storage.
94 *
95 * @param int $id
96 * @return \Illuminate\Http\Response
97 */
98 public function destroy($id)
99 {
100 //
101 }
102 }
103
104
将表单的验证移动到生成的Requests/QuestionStoreRequest.php文件内，代码如下：
1 <?php
2
3 namespace App\Http\Requests;
4
5 use Illuminate\Foundation\Http\FormRequest;
6
7 class QuestionStoreRequest extends FormRequest
8 {
9 /**
10 * Determine if the user is authorized to make this request.
11 *
12 * @return bool
13 */
14 public function authorize()
15 {
16 //一般判断当前用户是否有权发送本实例的请求,先默认设置为true，不过可以先写一个判断当前用户是否是请求中的用户来判断返回值
17
18 return true;
19 }
20
21 /**
22 * Get the validation rules that apply to the request.
23 * 验证规则
24 * @return array
25 */
26 public function rules()
27 {
28 return [
29 //
30 'title' => 'required|min:8',
31 'content' => 'required|min:28',
32 ];
33 }
34
35 public function messages()
36 {
37 // return parent::messages(); // TODO: Change the autogenerated stub
38 //错误提示
39 return [
40 'title.required' => '标题必须要输入的哦！',
41 'title.min' => '标题长度要大于8个的哦！',
42 'content.required' => '内容必须要输入的哦！',
43 'content.min' => '内容长度必须要大于28个的哦！',
44 ];
45 }
46 }
47
