how to call controllers from the cakephp default layout? - php

Question

I have a controller called UsersController, is there a way I can output some values from this controller to the cakephp default layout?
Here is what I have tried, the default.ctp:
<?php foreach ($users as $user): ?>
<ul class="nav navbar-nav navbar-right">
<?php if (!$this->Session->read('Auth.User.id')) : ?>
<li>
<?php echo $this->Html->link('Login',array('controller' => 'us 'action' => 'login', 'full_base' =>'true)); ?></li>
<li>
<?php echo $this->Html->link('Register', array('controller' => 'users', 'action' => 'add', 'full_base' => true)); ?>
</li>
<?php else: ?>
<li class="dropdown">
<a href="<?php echo $this->Html->url(array('controller' => 'users', 'action' => 'edit', 'full_base' => true)); ?>" class="dropdown-toggle" data-toggle="dropdown">
<?php if(empty($user[ 'User'][ 'filename'])){ ?>
<i class="fa fa-user fa-lg"></i>
<?php }else{ echo $this->Html->image($user['User']['filename'], array('alt' => $user['User']['username'],'class'=>'img-responsive img-rounded','width'=>'32','height'=>'32','style'=>'display:inline; background:red;')); } ?>
<?php $users[ 'User'][ 'username']; ?> <span class="caret"></span>
</a>
<ul class="dropdown-menu" role="menu">
<li>
<i class="fa fa-gear fa-lg"></i> Settings
</li>
<li>
<i class="fa fa-power-off fa-lg"></i> Logout
</li>
<li>Something else here
</li>
<li class="divider"></li>
<li>Separated link
</li>
</ul>
</li>
<?php endif; ?>
</ul>
<?php endforeach; ?>
And here is my AppController.php:
public function beforeFilter(){
return $this->getuser();
}
public function getuser($id = null){
$this->loadModel('User');
$user = $this->User->find('all', array(
'conditions' => array('User.id' => $id)
));
$this->set('users',$user);
}
The problem with this code is that,it keeps returning the following notice,
Notice (8): Undefined index: User [APP\View\Layouts\default.ctp, line
71]
please how do i resolve this issue?

Answer 1

If you want all fields from logged user, you can use this in your view.
$user = $this->Session->read('Auth.User'));
This will return all storage data from users ( username, filename, all fields from user table)

Answer 2

Just change in your controller you have used
public function getuser($id = null){
insted of this use
public function beforeRender($id = null) {
Your AppController.php code should look like this
public function beforeFilter(){
return $this->getuser();
}
public function beforeRender($id = null){
$this->loadModel('User');
$user = $this->User->find('all', array(
'conditions' => array('User.id' => $id)
));
$this->set('users',$user);
}
