总结7.20 laravel自动验证

方式一：控制器内直接验证

  Input::method()得到获取方法；

  public function valite(Request $request){

    $this->validate($request,[

      'title' => "required" //验证的规则

],[

   'title.required' => "标题是必填的"

]);

  }

方式二，独立方式去验证表单

namespace App\Http\Controllers;

use Validator;

use Illuminate\Http\Request;

use App\Http\Controllers\Controller

//需要引入验证和控制器的各种类;

class PostController extends Controller

{

    public function store(Request $request)

    {

        $validator = Validator::make($request->all(), [

            'title' => 'required|unique:posts|max:255',

            'body' => 'required',

        ]);

        if ($validator->fails()) {

            return redirect('post/create')

                        ->withErrors($validator)

                        ->withInput();

        }

    }

}

方式三、验证器

php artisan make:request 验证器的名称

 public function aaaa(){

 

　　return true；

 

}

 

 public function rule()

 

    {

 

     return [

 

            'title' => 'required|unique:posts|max:255',

 

            'body' => 'required',

 

        ]);

 

    }
