我如何在 laravel 的模型中编写验证？

Question

当我在控制器中验证 电话号码 时，它正在工作，但它增加了代码行数，我还必须编写回调函数，但我不想编写回调,而不是我想在模型中做，有什么办法吗？？

'phone' =>['required',"regex:/^\(?[\d]{3}\)?[\s-]?[\d]{3}[\s-]?[\d]{4}$/",function($attribute, $value, $fail) use($id) {

                    if (strpos($value, "-") !== false) {
                        $exist = User::where([["phone", $value],["id","!=",$id]])->count();
                        if($exist){
                            $fail(ucwords($attribute).' is already taken.');
                        }else{
                            $result = User::where([["phone", str_replace("-","",$value)],["id","!=",$id]])->count();
                            ($result) ?  $fail(ucwords($attribute).' is already taken.') : "";
                        }

                    }else{
                        $exist = User::where([["phone", $value],["id","!=",$id]])->count();
                        if($exist){
                            $fail(ucwords($attribute).' is already taken.');
                        }
                    }
                },],

我认为您应该能够将模型中的函数定义为返回闭包的静态函数，这样您就可以调用它来获取闭包并将其作为回调传递。

// In the model
public static function myValidationClosure($id){
   return function($attribute, $value, $fail)use($id) {
     if (strpos($value, "-") !== false) {
         $exist = User::where([["phone", $value],["id","!=",$id]])->count();
         if($exist){
             $fail(ucwords($attribute).' is already taken.');
         }else{
             $result = User::where([["phone", str_replace("-","",$value)],["id","!=",$id]])->count();
             ($result) ?  $fail(ucwords($attribute).' is already taken.') : "";
         }
     }else{
         $exist = User::where([["phone", $value],["id","!=",$id]])->count();
         if($exist){
             $fail(ucwords($attribute).' is already taken.');
         }
     }
   };
 }

然后你可以在验证中使用它作为

'phone' =>['required',"regex:/^\(?[\d]{3}\)?[\s-]?[\d]{3}[\s-]?[\d]{4}$/", MyModelClass::myValidationClosure($id)]

对于验证而言，好的解决方案总是提出一个单独且易于处理的自定义请求，请遵循此 =>

php artisan make:request CustomRequest

请求：

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use App\User;

class CustomRequest 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()
    {
        return [

            'phone'        => [
                                    'required',

                                    'min:10', 
                                    'max':10',             
                                    'regex:/^\(?[\d]{3}\)?[\s-]?[\d]{3}[\s-]?[\d]{4}$/',     

                                 ],

        ];
    }
}

它将为您提供默认验证消息，但如果您想制作自定义消息，您可以通过 message() 来完成
