Php 如何在laravel中的模型中编写验证？

当我验证电话号码时控制器工作正常，但它增加了代码行，我还必须编写回调函数，但我不想编写回调函数，而是想在模型中执行，有什么方法可以执行吗

'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.');
                        }
                    }
                },],

对于验证来说，最好的解决方案是创建一个单独且易于处理的自定义请求，如下=>

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}$/',     

                                 ],

        ];
    }
}

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.');
         }
     }
   };
 }

然后您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)]

谢谢，我明白了，但是有没有办法不写我正在使用的回调，因为正如您所建议的那样，它只验证正则表达式，但不会验证数据库中是否存在该数字，或者是否与回调中一样。再次感谢。
