php - $this->Auth->user(); 只有 id 而不是整个数组

Question

我正在为 CakePHP 2.x 中的 auth-componentent 苦苦挣扎 这本书在这里说 （底部的最后一个条目）

$this->Auth->user();

如果参数为空，则返回所有用户数据。

"$key (string) – The user data key you want to fetch. 
If null, all user data will be returned."

但如果我回声$u

$u = $this->Auth->user();

然后只显示用户ID。我期望整个用户数组。有任何想法吗？

Answer 1

$this->Auth->user();

返回值是数组，因此如果您只想打印整个内容以进行调试，请尝试

$u = $this->Auth->user();
var_dump($u);

或者

print_r($u);

Answer 2

As Mark (DerEuroMark) expected in the comment, my login script was wrong. For some reason I stored the array too flat. The login code was wrong. I fixed the login code (respectively I wrote it from scatch and now everything works fine. Thank you anyway for all the replies.

Answer 3

$u = $this->Auth->user();

返回一个关联数组，您可以通过表中的键访问字段，例如

echo $u['username']; 
echo $u['email'];

Answer 4

$u = $this->Auth->user();

Yes you are trying echo $u;

在下面尝试此尝试

vardump($u); or print_r($u);

如果这对你有帮助，现在让我说。

谢谢

Answer 5

试试这个代码............ pr($this->Auth->user());

Answer 6

 $this->Auth->user();

从用户表返回数据，您应该使用

 $id= $this->Auth->user('id');

获取 id
