问题描述
我有两个字段password（此字段在数据库中）和confirm_password（此字段不在数据库中）
I have two field "password" (This field is in the database) and confirm_password (This field is not in the database)
如果password == confirm_password ..但我不知道创建一个自定义验证confirm_password...需要在数据库中有这个字段吗？
Well, I need to compare if password == confirm_password.. but I'm not knowing create a custom validation to "confirm_password"... Would need to have this field in the database?
如何
推荐答案
通常，您可以访问。 $ context 参数，其中它存储在 data 键，即 $ context ['data'] ['confirm_password'] ，然后可以与当前字段值进行比较。
Generally you can access all data in a custom validation rule via the $context argument, where it's stored in the data key, ie $context['data']['confirm_password'], which you could then compare to the current fields value.
$validator->add('password', 'passwordsEqual', [
'rule' => function ($value, $context) {
return
isset($context['data']['confirm_password']) &&
$context['data']['confirm_password'] === $value;
}
]);
话虽如此，最近还有一个 compareWith 验证规则。
That being said, recently a compareWith validation rule was introduced which does exactly that.
https://github.com/cakephp/cakephp/pull/5813
$validator->add('password', [
'compare' => [
'rule' => ['compareWith', 'confirm_password']
]
]);
