CakePHP Auth 组件验证问题

Question

有些验证问题似乎只在使用 Auth 组件时出现。 我的注册表中有 4 个字段：username、password、password_confirm 和 email。

我的用户模型也附加了多重验证行为。以下是适用于注册表的规则：

var $validationSets=array(
    "register" => array(
        "username" => array(
            "usernameFieldNotEmpty" => array(
                "rule" => "notEmpty",
                "message" => "You did not enter the username!"
            ),
            "usernameValid" => array(
                "rule" => "__alphaNumericDashUnderscore",
                "message" => "The username you entered is not valid!"
            ),
            "usernameExistsInDatabase" => array(
                "rule" => array("__existingRecord", false), 
                "message" => "The username you entered has been already registered in our database!"
            )
        ),
        "password" => array(
            "passwordFieldNotEmpty" => array(
                "rule" => "notEmpty",
                "message" => "You did not enter your password!"
            )
        ),
        "password_confirm" => array(
            "passwordConfirmFieldNotEmpty" => array(
                "rule" => "notEmpty",
                "message" => "You did not confirm your password!"
            ),
            "passwordsMatch" => array(
                "rule" => array("__fieldMatch", "password"),
                "message" => "The passwords you entered don't match!"
            )
        ),
        "email" => array(
            "emailFieldNotEmpty" => array(
                "rule" => "notEmpty",
                "message" => "You did not enter the e-mail!"
            ),
            "emailValid" => array(
                "rule" => "email",
                "message" => "The e-mail you entered is not valid!"
            ),
            "emailExistsInDatabase" => array(
                "rule" => array("__existingRecord", false), 
                "message" => "The e-mail you entered has been already registered in our database!"
            )
        )
        /*"language" => array(

        )*/
    )

这是我的注册表：

<?php echo $this->Form->create('User', array('url' => array('controller' => 'users', 'action' => 'register')));?>
<fieldset>
    <legend><?php __('Add User'); ?></legend>
<?php
    echo $this->Form->input('username');
    echo $this->Form->input('password', array('type' => 'password', 'value' => ''));//value='' - resets the password input on any error on the page
    echo $this->Form->input('password_confirm', array('type' => 'password', 'value' => ''));
    echo $this->Form->input('email');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit', true));?>

现在，每次我提交 EMPTY 表单时，密码字段虽然为空，但通过了所有验证测试（我尝试将 value => '' 放入代码中，但没有用）。 此外，电子邮件输入似乎通过了'notEmpty' 测试，显示的错误是The email is not valid

我查看了所有代码，但找不到任何解决方案。

我已经设法进行了几次“破解”，所以现在问题已经解决了。 不要认为这是最合适的方法，但它可能会为其他遇到我问题的用户派上用场：

首先，在我的UsersController中，我写了这个sn-p，所以如果密码字段被用户留空，在验证之前将其重置为''：

if($this->data['User']['password'] == $this->Auth->password('')){
            $this->data['User']['password'] = '';
        }
        $this->User->set($this->data);
        if($this->User->validates()){ //post validation login }

第二个问题是电子邮件验证。奇怪的是，我通过更改 Multivalidatable Behaviour 中的规则顺序解决了这个问题。所以，来自：

"email" => array(
        "emailFieldNotEmpty" => array(
            "rule" => "notEmpty",
            "message" => "You did not enter the e-mail!"
        ),
        "emailValid" => array(
            "rule" => "email",
            "message" => "The e-mail you entered is not valid!"
        ),
        "emailExistsInDatabase" => array(
            "rule" => array("__existingRecord", false), 
            "message" => "The e-mail you entered has been already registered in our database!"
        )
    )

我现在有：

"email" => array(
            "emailExistsInDatabase" => array(
                "rule" => array("__existingRecord", false), 
                "message" => "The e-mail you entered has been already registered in our database!"
            ),
            "emailValid" => array(
                "rule" => "email",
                "message" => "The e-mail you entered is not valid!"
            ),
            "emailFieldNotEmpty" => array(
                "rule" => "notEmpty",
                "message" => "You did not enter the e-mail!"
            )
        )

我不知道这是否是有意的，但似乎显示的是未满足的 last 规则。按照我的逻辑，规则会按照出现的顺序排列，所以如果第一个不适用，请停止检查并显示它。

我再说一遍，我不知道这是否是正确的方法，但我似乎已经解决了这些问题。

如果你有什么要补充的，请补充！

编辑 在 Cake 1.3 Book 中找到了“官方”解释。它说：

By default CakePHP tries to validate a field using all the validation rules declared for it and returns the error message for the last failing rule. But if the key last is set to true for a rule and it fails, then the error message for that rule is returned and further rules are not validated. So if you prefer to show the error message for the first failing rule then set 'last' => true for each rule.

因此，解决我的问题的另一种方法是按出现顺序设置验证规则，并将last 键添加到规则数组中。

关于密码问题：您使用的是什么版本的 CakePHP？

1.2 中的 Auth 组件会自动对您的密码进行哈希处理，因此即使是，它也不会为空。 1.3应该没问题，但不知道是哪个版本的。
