Controller/PagesController.php

class PagesController extends AppController {

/**
 * This controller does not use a model

    public $uses = array();

/**
 * Displays a view
 *
 * @param mixed What page to display

 public function display() {
     $this->loadModel('Usermgmt.User');
 //$id=null;
    //for home page
    if(isset($id)){

        $users=$this->User->findByuser_group_id($id);
        $this->set('users', $users);
        }
        else{
        $users=$this->User->find('all');
        $this->set('users', $users);
        }
        /*$users=$this->User->find('all');
        $this->set('users', $users);*/
 //end home page

        $path = func_get_args();

        $count = count($path);
        if (!$count) {
            return $this->redirect('/');
        }
        $page = $subpage = $title_for_layout = null;

        if (!empty($path[0])) {
            $page = $path[0];
        }
        if (!empty($path[1])) {
            $subpage = $path[1];
        }
        if (!empty($path[$count - 1])) {
            $title_for_layout = Inflector::humanize($path[$count - 1]);
        }
        $this->set(compact('page', 'subpage', 'title_for_layout'));

        try {
            $this->render(implode('/', $path));
        } catch (MissingViewException $e) {
            if (Configure::read('debug')) {
                throw $e;
            }
            throw new NotFoundException();
        }
    }
}

here when i click the menu if(isset($id)){ function not working shows error as

Missing View Error: The view for PagesController::display() was not found. Error: Confirm you have created the file: E:\wamp\www\CMS\app\View\Pages\home\9.ctp

Answer 1

What written on Cakephp documentation about PagesController is-

CakePHP ships with a default controller `PagesController.php`. This is a simple and optional controller for serving up `static content`.

So, PagesController is good for static pages like-aboutus, contactus something but not good for dynamic pages..

A url like www.example.com/{controller}/{action} Generally search for action on Controller but for PagesController you don't need to define extra {action} because all url to PagesController will map to display action.

So, www.example.com/pages/about_us will map to display action and if you try to pass any extra argument to url, you will face that problem...

Answer 2

For creating views for controller PagesController, you have to create folder named Pages not pages

It clearly says:

Missing View Error: The view for PagesController::display() was not found. 
Error: Confirm you have created the file: E:\wamp\www\CMS\app\View\Pages\home\9.ctp

Pages\home\9.ctp here Pages is the folder name that is case sensitive. So change the folder name from pages to Pages.

This will solve the above error.
