Question

我添加了一条规则来检查更新用户记录中的先前密码，但该规则也适用于创建记录，我添加了“更新”但仍然无效。

$validator
->scalar('password')
->maxLength('password', 25)
->notEmpty('password', 'Password is required', 'create')
->allowEmpty('password', 'update')
->add('password', 'validFormat', [
        'rule' => ['custom', '/^(?=.*[!@$])(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9]).{6,16}$/i'], 
        'message' => __('Minimum 6 character & alphanumeric with one symbol(!@$) is Required.'), 
        'allowEmpty' => true
])
->add('password', 'custom', [
    'rule' => function($value, $context){
        $user = $this->get($context['data']['id']);

        if ($user) {
            if (!(new DefaultPasswordHasher)->check($value, $user->password)) {
                return true;
            }
        }
        return false;
    }, 
    'message' => 'You cannot use your previous password',
    'allowEmpty' => true
], 'update');

添加updated没有做任何事情，因为它不是CakePHP支持的。

如果您阅读Custom Validation Rules，您会看到可以使用$ context ['newRecord']来确定这是更新还是创建。

因此，验证函数的第一行可能类似于

if ($context['newRecord']){
    return true; //new passwords are always valid!
}

替代方法是检查$ user变量并添加else分支

if($user){
    //you already have code here
}else{
    //add this else to return TRUE because for new user, new password is OK
    return true;
}
