CakePHP 2.x身份验证自定义用户名（代码到位但不起作用！）

对不起，我不想问，但我已经花了一个小时的时间来解决这个问题和研究，但没有任何运气

CakePHP（运行最新版本）似乎拒绝使用字段设置（这样我就可以使用数据库中的email列作为用户名）。如果我将其设置为“email”，这是我希望从数据库中使用的字段，它只会拒绝登录并声明错误的详细信息。由于某些原因，无法从DebugKit中的SQL获取任何输出。虽然当它被设置为username时，只要在数据库中使用一个“temp”列就可以了。我试着把它放在组件变量中，但也没有成功。我可能做错了什么？调试已打开，在日志或浏览器中看不到任何错误

该模型确实包含电子邮件列

尝试更新appController中的组件代码，将身份验证值添加到身份验证数组，如下所示：

public $components = array(
            'Session',
            'DebugKit.Toolbar',
            'Auth' => array(
                    'allow' => array('login','logout'),
                    'loginAction' => array('controller' => 'users', 'action' => 'login'),
                    'loginRedirect' => array('controller' => 'dashboard', 'action' => 'index'),

您需要将表单上字段的名称从用户名更改为电子邮件。仅仅将标签设置为“电子邮件”是不够的

        echo $this->Form->input('email',array(
            'between' => '<br/>',
            'before' => '<p>',
            'after' => '</p>',
            'class' => 'text',
            'label' => 'Email:'

echo$this->Form->input（'email'，数组(
'在'=>'
'之间，
'在'=>''之前，
'在'=>'之后
'，
“类”=>“文本”，
'标签'=>'电子邮件：'
