Laravel：更新时验证 alpha 和正则表达式模式

Question

你好，这是我的用户更新控制器。我想知道如何将这些 laravel 验证规则仅应用于更新的字段。目前，当我只更新名字时，手机号码也会得到验证。我的姓名字段经过 alpha 验证，phone 数字通过正则表达式验证。

public function update(Request $request, User $setting)
    {
         request()->validate([
            'name' => ['required', 'alpha','min:2', 'max:255'],
            'last_name' => ['required', 'alpha','min:2', 'max:255'],
            'mobile'=>['required', 'string','regex:/\+(9[976]\d|8[987530]\d|6[987]\d|5[90]\d|42\d|3[875]\d|
            2[98654321]\d|9[8543210]|8[6421]|6[6543210]|5[87654321]|
            4[987654310]|3[9643210]|2[70]|7|1)\d{1,14}$/'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users,email,'.$setting->id.''],
        ]);

        $setting->update($request->all());


                        return Redirect::back()->with('success','User updated successfully');                
    }

我能够处理电子邮件（唯一）字段，但不能处理其他字段。

考虑到我们在评论中的闲聊，您必须做的是首先从数据库中获取模型并将请求与模型的属性进行比较。然后你可以只保留更改属性的验证规则。

public function update(int $id, Request $request, User $userRepository)
{    
     $user = $userRepository->find($id);

     $changedAttributes = array_diff($request->all(), $user->getAttributes());

     $validationRules = array_intersect_key([
        'name'      => ['required', 'alpha','min:2', 'max:255'],
        'last_name' => ['required', 'alpha','min:2', 'max:255'],
        'mobile'    => ['required', 'string', 'regex:/\+(9[976]\d|8[987530]\d|6[987]\d|5[90]\d|42\d|3[875]\d|
        2[98654321]\d|9[8543210]|8[6421]|6[6543210]|5[87654321]|
        4[987654310]|3[9643210]|2[70]|7|1)\d{1,14}$/'],
        'email'     => ['required', 'string', 'email', 'max:255', 'unique:users,email,'.$setting->id.''],
    ], $changedAttributes);

    $this->validate($request, $validationRules);

    $user->update($changedAttributes);

    return Redirect::back()->with('success','User updated successfully');                
}
