与其他领域相关的Cakephp自定义验证

Question

我在cakephp的croogo 1.3工作，所以我想制作一个表格。看我的截图：

）

它有两部分：

1. 部分[使用] [名称] [密码] [电子邮件]
2. 胎次（这是所有领域）

如果选中复选框'profossionnel'，我想检查（验证）所有字段，否则只验证此字段[使用] [名称] [密码] [电子邮件]

这是我测试的源代码，但它没有用：

public $validate = array(
        'username' => array(
            'isUnique' => array(
                'rule' => 'isUnique',
                'message' => 'The username has already been taken.',
                'last' => true,
            ),
            'notEmpty' => array(
                'rule' => 'notEmpty',
                'message' => 'This field cannot be left blank.',
                'last' => true,
            ),
            'validAlias' => array(
                'rule' => 'validAlias',
                'message' => 'This field must be alphanumeric',
                'last' => true,
