建立验证规则文件

php artisan make:request ArticleValidate

`http/Requests/ArticleValidate.php`中设置验证规则如下：

<?php
    
    namespace App\Http\Requests;
    
    use Illuminate\Foundation\Http\FormRequest;
    
    class ArticleValidate 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()
        {
            switch ($this->method()) {
                case 'POST':
                    return [
                        'title' => 'required|unique:articles|max:255',
                        'content' => 'required',
                        'description' => 'required',
                        'keywords' => 'required'
                    ];
                case 'PUT':
                    return [
                        'title' => 'required|max:255',
                        'content' => 'required',
                        'description' => 'required',
                        'keywords' => 'required'
                    ];
            }
        }
    }

控制器引用验证

public function update(ArticleValidate $request, $id)
        {
            $article=Article::find($id);
            $data = $request->all();
            unset($data['image']);
            $article->update($data);
            return redirect('/admin/article');
        }

前端`form`表单标签上方，加上如下验证提示代码：

@if (count($errors) > 0)
                                <div class="am-alert am-alert-danger" data-am-alert>
                                    <button type="button" class="am-close">×</button>
                                    <ul>
                                        @foreach ($errors->all() as $error)
                                            <li>{
       { $error }}</li>
                                        @endforeach
                                    </ul>
                                </div>
                            @endif
    
    
                        @if (session('success'))
                            <div class="am-alert am-alert-block am-alert-success flash_msg">
                                {
       { session('success') }}
                            </div>
                        @endif
    
    
                        @if (session('error'))
                            <div class="am-alert am-alert-block am-alert-danger flash_msg">
                                {
       { session('error') }}
                            </div>
                        @endif
