表单验证

表单验证

基于 laravel 的验证器扩展了自动验证与场景支持。

• 验证类库 app/Http/Validate/Validate.php

  <?php
  namespace App\Http\Validate;
  use Illuminate\Support\Facades\Validator;
  class Validate {
      //当前场景
      protected $scene = null;
      //错误信息
      protected $error = null;
      //验证规则
      protected function rule(){
          return [];
      }
      //提示信息
      protected function message(){
          return [];
      }
      //场景规则
      protected function rules(){
          return [];
      }
      //设置场景
      public function scene($name){
          $this->scene = $name;
          return $this;
      }
      //数据验证
      public function check($data,$rule=[],$message=[],$rules=[]){
          //...
      }
      // 获取错误信息
      public function getError(){
          return $this->error;
      }
  }
  
  
• 示例代码
  1. 验证规则 app/Http/Validate/Login.php

     <?php
     namespace App\Http\Validate;
     use Illuminate\Http\Request;
     use Illuminate\Support\{Str,Arr};
     use Illuminate\Validation\Rule;
     class Login extends Validate {
         public $validate;
         public $controller;
         public function __construct(Request $request){
             //控制器规则
             $this->validate=[
                 'check'=>[
                     'rule'=>[
                         'user' => ['required'],
                         'pwd' => ['required']
                     ],
                     'message'=>[
                         'user.required' => '用户名不可为空',
                         'pwd.required' => '密码不可为空'
                     ]
                 ]
             ];
             //获取控制器
             $this->controller=Str::after($request->route()->getActionName(),'@');
         }
         //验证规则
         public function rule(){
             $rule=Arr::get($this->validate,$this->controller.'.rule',[]);
             return $rule;
         }
         //提示信息
         public function message(){
             $message=Arr::get($this->validate,$this->controller.'.message',[]);
             return $message;
         }
         //场景规则
         public function rules(){
             $rules=Arr::get($this->validate,$this->controller.'.rules',[]);
             return $rules;
         }
     }
     
  2. 数据验证

     <?php
     namespace App\Http\Controllers;
     use Illuminate\Http\Request
     use App\Http\Validate\Login as Validate;
     class Login extends Controller {
         //登录验证
         public function check(Request $request,Validate $validate){
             $input=$request->input();
             $verify=$validate->check($input);
             if($verify){
                 //验证成功
             }else{
                 //验证失败
             	$err=$validate->getError();
             }
         }
     }
