For deleting user information in cake php by clicking on delete button we have to first pass user id in URL by using below code in our view.

<?php echo $this->Html->link('Delete',array('action'=>'del'.$user['User']['id'])); 

And we have to put the following code in that function where we will wright code for deleting data in our controller.

 public function delete($id) { // here we are getting $id from the url   
       
        
     
       if(isset($id) && !empty($id)){ // checking wheather we are getting id from url or not
          $user = $this->Auth->User('id'); //finding user details by the id
          if($id== $user){
            $this->User->delete($id); 
            $this->redirect(array('action' => 'logout'));
        }
        $this->Session->setFlash('you cant delete this user');
        $this->redirect(array('action' => 'display'));
        }
        else{

            $this->redirect(array('action' => 'display'));
        }
    
    
   }
