[英]how to get a value of id from database table in cakephp
CAKEPHP CAKEPHP
I have problem to get id value from table 我从表获取ID值有问题
My table is named "users"
and have id PK(int),username(txt) name(txt)
我的表名为"users"
并且具有ID PK(int),username(txt) name(txt)
I have tried 我努力了
$this->users->read('users.id)
To get user id but it doesn't work. 获取用户ID,但不起作用。
I also tried 我也试过
$this->request->session()->read('users.id')
I wanna to make a condition like 我想让像
if($this->users->read('users.id'))==1
because I wanna hide html code from users with other id. 因为我想向具有其他ID的用户隐藏html代码。 I also try use something like that ..... read('users.username')=='admin'
but they wont work too 我也尝试使用类似的方法..... read('users.username')=='admin'
但它们也无法正常工作
As you see a try to use session() to get id but dont work to 如您所见,尝试使用session()获取ID,但不尝试
my login function is 我的登录功能是
public function login()
{
if ($this->request->is('post')) {
$user = $this->Auth->identify();
if ($user) {
$this->Auth->setUser($user);
return $this->redirect(['controller'=>'Accounts']);
}
$this->Flash->error('blalalalala');
}
}
This is my first project i cakephp to school so guys can you help me? 这是我第一次上学的蛋糕,所以你们可以帮我吗? :) im weak in php :)我在php中比较弱
Thx for tips but still dont work. 谢谢技巧,但仍然无法正常工作。
i use this 我用这个
$id = $this->Auth->user('id'); // To get user id
$this->set('id', $id);
in my AppController in funciton before filter. 在过滤器之前在我的AppController中起作用。
and i use for example if($id==1)
..... and still dont work. 而且我使用例如if($id==1)
.....仍然不起作用。 var dump shows null. var dump显示为空。
i forgot to say but i have CakePHP 3x version
我忘了说,但是我有CakePHP 3x version
To set user any information in controller you can use 要在控制器中为用户设置任何信息,您可以使用
$this->Auth->user('fieldName');
In AppController
in beforeFilter
method just set user info which you need, like as below code 在AppController
中的beforeFilter
方法中,只需设置所需的用户信息即可,如下面的代码所示
$id = $this->Auth->user('id'); // To get user id
$this->set('id', $id);
Now in any view you can apply condition like 现在,在任何视图中,您都可以应用条件
if($id==1)
--do this--
If you want to get user id anywhere you can use, It not allow in cakephp 3.x 如果您想在任何可以使用的地方获取用户ID,则在cakephp 3.x中不允许
AuthComponent::user('id')
you can try these: 您可以尝试以下方法:
$this->Auth->user('id'); // for controller action
OR 要么
$this->Session->read('Auth.User.id'); // for controller and views
OR 要么
AuthComponent::user('id') // anywhere
