Laravel 5.3使用自定义验证 [英] Laravel 5.3 use custom validation

问题描述

我使用Laravel 5.3.我想使用表单验证来测试用户密码的哈希值.

I use Laravel 5.3. I want to use form validation to test the hash for user's password.

这是我的代码:

$validator = Validator::make($request->all(), [
    'old_password' => 'required|max:20|min:6',
    'new_password' => 'required|max:20|min:6',
    'new_password_confirm' => 'required|same:new_password',
]);

// test old password
if (! Hash::check($request->old_password, $user->user_passwd)) {
    $validator->errors()->add('end', 'The end time must be within three hours of the start');
}

即使验证了条件，这也不起作用.我已经测试过了:

This is not working, even if the conditon is verified. I've tested this :

Validator::extend('old_password', function($attribute, $value) use ($user) {
    return Hash::check($value, $user->user_passwd);
});

但我不知道该如何使用?

But I don't understand how to use this ?

解决方案:

好的，以简单的方式完成此操作的最佳方法是，将扩展名放在make之前:

Ok, the best way to do it in simple way, place the extend before the make :

Validator::extend('checkPassword', function ($attribute, $value, $parameters, $validator) use($user) {
     return Hash::check($value, $user->user_passwd);
}, 'Your message error !');

$validator = Validator::make($request->all(), [
     'old_password' => 'required|max:20|min:6|checkPassword',
     'new_password' => 'required|max:20|min:6',
     'new_password_confirm' => 'required|same:new_password',
]);

推荐答案

您的自定义规则old_password可以这样使用

Your custom rule old_password can be used like this

$validator = Validator::make($request->all(), [
    'old_password' => 'required|max:20|min:6|checkpassword',
    'new_password' => 'required|max:20|min:6',
    'new_password_confirm' => 'required|same:new_password',
]);

扩展验证器. CheckPassword是带有isValid()方法的类.

Extend validator. CheckPassword is class with method isValid().

Validator::extend('checkpassword', function ($attribute, $value, $parameters, $validator) {
            return (new CheckPassword($attribute, $value, $parameters, $validator))->isValid();
        });

CheckPassword.php将类似于

CheckPassword.php will be like

/**
 * Attribute being tested
 *
 * @var mixed
 */
protected $attribute;

/**
 * Value of the attribute
 *
 * @var mixed
 */
protected $value;

/**
 * Array of parameters passed to the value
 *
 * @var array
 */
protected $parameters;

/**
 * Validator instance
 *
 * @var mixed
 */
protected $validator;
/**
 * Class constructor
 *
 * @param mixed $attribute
 * @param Uploaded $value
 * @param array $parameters
 * @param mixed $validator
 */
public function __construct($attribute, $value, $parameters, $validator)
{
    $this->attribute = $attribute;
    $this->value = $value;
    $this->parameters = $parameters;
    $this->validator = $validator;
}

public function isValid()
{
  $value = $this->value; //Old password Value
  //after this you can check hash and return true or false.
}
