laravel unique驗證、確認密碼confirmed驗證以及密碼修改驗證的方法

confirmed

驗證字段必須有一個匹配字段 foo_confirmation，例如，如果驗證字段是 password，必須輸入一個與之匹配的 password_confirmation 字段。

same:field

給定字段和驗證字段必須匹配

 protected $fillable = ['name', 'password'];
 
 public static $rules = [
  'name'   => 'required|unique:managers',
  'password' => 'required|confirmed',
  'password_confirmation' => 'required|same:password'
 ];
 
 public static function error_message() 
 {
  return [
   'name.required' => __('tyvalidation.name'),
   'name.unique' => __('tyvalidation.unique'),
   'password.required' => __('tyvalidation.password'),
   'password.confirmed' => __('tyvalidation.confirmed'),
  ];
 }
 
 public function setPasswordAttribute($value)
 {
  $this->attributes['password'] = Hash::make($value);
 }

經(jīng)驗證，上面的驗證方式在update的時候會出問題，修改的時候會驗證unique，導致不能保存，所以需要修改下。

官網(wǎng)說：

Sometimes, you may wish to ignore a given ID during the unique check. For example, consider an "update profile" screen that includes the user's name, e-mail address, and location. Of course, you will want to verify that the e-mail address is unique. However, if the user only changes the name field and not the e-mail field, you do not want a validation error to be thrown because the user is already the owner of the e-mail address.

To instruct the validator to ignore the user's ID, we'll use the Rule class to fluently define the rule. In this example, we'll also specify the validation rules as an array instead of using the |character to delimit the rules:

重要的2句話是：

有時，您可能希望在唯一檢查期間忽略給定的ID。

當然，您需要驗證電子郵件地址是否唯一。但是，如果用戶僅更改名稱字段而不更改電子郵件字段，則不希望拋出驗證錯誤，因為用戶已經(jīng)是電子郵件地址的所有者，為了指示驗證者忽略用戶的ID，我們將使用Rule該類來流暢地定義規(guī)則。

use Illuminate\Validation\Rule;
 
Validator::make($data, [
  'email' => [
    'required',
    Rule::unique('users')->ignore($user->id),
  ],
]);

所以修改為

'name'   => [
     'required',
     Rule::unique('managers')->ignore($id),
    ],

在更新密碼時，我們需要驗證舊的密碼是否正確，那我們需要使用自定義驗證。

Using Closures

If you only need the functionality of a custom rule once throughout your application, you may use a Closure instead of a rule object. The Closure receives the attribute's name, the attribute's value, and a $fail callback that should be called if validation fails:

Closure接收屬性的名稱，屬性的值以及$fail在驗證失敗時應調(diào)用的回調(diào)。

$validator = Validator::make($request->all(), [
  'title' => [
    'required',
    'max:255',
    function($attribute, $value, $fail) {
      if ($value === 'foo') {
        return $fail($attribute.' is invalid.');
      }
    },
  ],
]);

所以密碼是否正確可以這樣驗證

'old_password' => [
     'required',
     function($attribute, $value, $fail) use ($manager) 
     {
      if (!Hash::check($value, $manager->password)) 
      {
       return $fail(__('tyvalidation.old_password'));
      }
     },
    ],

所有代碼如下：

create.html

div class="form-group">
      label>{!! __('tycms.name') !!}/label>
      div class="input-group">
       div class="input-group-prepend">
        span class="input-group-text change-bg">T/span>
       /div>
       input type="text" class="form-control is-invalid" name="name" value="" placeholder="{!! __('tycms.name') !!}" required />
       @foreach ($errors->get('name') as $message) 
       div class="invalid-feedback">
        {{ $message }}
       /div>
       @endforeach
