Limit results seen by users

Feb 8th

Posted by Twitter in CakePHP

Here are a couple of nifty functions I came across, to limit the results that are returned in a Cake app.

When using the find() function, by default it will return all of the results. These two methods if placed in the appModel will only return results that are associated with a given user.

<?php  
function findMy($type, $options=array()) 
{ 
   if($this->hasField('user_id') && !empty($_SESSION['Auth']['User']['id'])){ 
      $options['conditions'][$this->alias.'.user_id'] = $_SESSION['Auth']['User']['id']; 
      return parent::find($type, $options); 
   } 
   else{ 
      return parent::find($type, $options); 
   } 
} 

function deleteMy($id = null, $cascade = true){ 
   if (!empty($id)) { 
      $this->id = $id; 
   } 
   $id = $this->id; 

   if($this->hasField('user_id') && !empty($_SESSION['Auth']['User']['id'])){ 
      $opt = array( 
         'conditions' => array( 
            $this->alias.'.user_id' => $_SESSION['Auth']['User']['id'], 
            $this->alias.'.id' => $id, 
            ), 
         ); 
      if($this->find('count', $opt) > 0){ 
         return parent::delete($id, $cascade); 
      } 
   } 
   return false 
} 
?>

Accessing user_id in CakePHP

Posted by Twitter in CakePHP

Add this to the model

class Foo extends AppModel {
  var $currentUsrId = NULL;
}

Then add this to the controller

class FooController extends AppController {
 function beforeFilter(){
  parent::beforeFilter();
  $this->Foo->;currentUsrId = $this->;Auth->user('id');
 }
}
