Re: Naviagation in a CakePHP application

Have you added 'Auth' into your $components variable in the AppController? 

Also, I think that Auth needs to be used from the controller - you could always dump the information you need to a variable in your controller and then pass it to the view for use.

I am new in CakePHP, trying to make an application. In this application, I have a navigation bar, whose Menus I want to be changed according to login status of a user. I think I can't explain clearly, please have a look at this code snippet :

This is my "header" part's(an "element") navigation bar:

           $list="";
           if($authUser)
           {
           $list=array(
                    $this->Html->link('Home',array('controller'=>'pages','action'=>'index')),
                    $this->Html->link('About',array('controller'=>'pages','action'=>'about')),array(
                                                                                                 $this->Html->tag('span',null,array('class'=>'top')),
                                                                                                 $this->Html->tag('span',null,array('class'=>'bottom')),
                                                                                                 $this->Html->link('Sub Menu 1',array('controller'=>'','action'=>'')),
                                                                                                 $this->Html->link('Sub Menu 2',array('controller'=>'','action'=>'')),
                                                                                                 $this->Html->link('Sub Menu 3',array('controller'=>'','action'=>'')),
                                                                                              ),
                    $this->Html->link('Gallery',array('controller'=>'pages','action'=>'gallery')),array(
                                                                                                     $this->Html->tag('span',null,array('class'=>'top')),
                                                                                                     $this->Html->tag('span',null,array('class'=>'bottom')),
                                                                                                     $this->Html->link('Sub Menu 1',array('controller'=>'','action'=>'')),
                                                                                                     $this->Html->link('Sub Menu 2',array('controller'=>'','action'=>'')),
                                                                                                     $this->Html->link('Sub Menu 3',array('controller'=>'','action'=>'')),
                                                                                                  ),
                    $this->Html->link('My Posts',array('controller'=>'pages','action'=>'myPosts/1')),
                    $this->Html->link('Blog',array('controller'=>'pages','action'=>'blog')),
                    $this->Html->link('Contact',array('controller'=>'pages','action'=>'contact')),
                    $this->Html->link('Logout',array('controller'=>'users','action'=>'logout'))
                 );
           }
           else
           {
           $list=array(
                    $this->Html->link('Home',array('controller'=>'pages','action'=>'index')),
                    $this->Html->link('About',array('controller'=>'pages','action'=>'about')),array(
                                                                                                 $this->Html->tag('span',null,array('class'=>'top')),
                                                                                                 $this->Html->tag('span',null,array('class'=>'bottom')),
                                                                                                 $this->Html->link('Sub Menu 1',array('controller'=>'','action'=>'')),
                                                                                                 $this->Html->link('Sub Menu 2',array('controller'=>'','action'=>'')),
                                                                                                 $this->Html->link('Sub Menu 3',array('controller'=>'','action'=>'')),
                                                                                              ),
                    $this->Html->link('Gallery',array('controller'=>'pages','action'=>'gallery')),array(
                                                                                                     $this->Html->tag('span',null,array('class'=>'top')),
                                                                                                     $this->Html->tag('span',null,array('class'=>'bottom')),
                                                                                                     $this->Html->link('Sub Menu 1',array('controller'=>'','action'=>'')),
                                                                                                     $this->Html->link('Sub Menu 2',array('controller'=>'','action'=>'')),
                                                                                                     $this->Html->link('Sub Menu 3',array('controller'=>'','action'=>'')),
                                                                                                  ),
                    $this->Html->link('Blog',array('controller'=>'pages','action'=>'blog')),
                    $this->Html->link('Contact',array('controller'=>'pages','action'=>'contact'))
                 );
                 }
           echo $this->Html->nestedList($list);

what I want, if a user is logged in "My Post" and "Logout" menus will be there, otherwise not. I am getting the value of the $authUser variable from all of the "View" files, when I set the "header" there. This is the code that I am keeping in all "View" files :

           echo $this->element('header',array("authUser"=>$this->Auth->loggedIn()),array("cache"=>"long_view"));
This creates 2 errors, saying "There is no Auth helper in the library" and "$authUser" could not be recognized, in the "header.ctp". What should I do now ?

By the way, I am using "AuthComponent" for user Login, Logout and SignUp. Should I use Session instead of Authentication, or mix of these 2, like when a user gets logged in, a new session value will be created and that will be checked whenever it needs to do that ?

I got some help from another developer, he gave me that "authUser" idea, I think it looks good, but that "Auth" helper creates problem.

Thanks
