Notice (8): Undefined variable: paginator [APP/views/elements/products.ctp, line 25] Fatal error: Call to a member function sort() on a non-object in /Applications/MAMP/htdocs/development03/app/views/elements/products.ctp on line 25

Controller

var $helpers = array('Html','Form','Ajax','Javascript', 'Text');

// Pagination 
var $paginate = array('limit' => 8, 'page' => 1,'order'=>array('Product.name' => 'asc')); 

function lists() {

    $categories = $this->Category->find('all', array('order' => 'Category.id ASC' ));       
    $categories = $this->Category->buildCategories($categories, $this->passedArgs['c']);
    $children_ids  = $this->Category->getChildCategories($categories, $this->passedArgs['c'], true);
    $allCatIds = array_merge(array($this->passedArgs['c']), $children_ids);
    //return lists
    return $this->Product->lists($allCatIds);
}

Element

<?php 

$products = $this->requestAction("/products/lists/c:$catId/"); 

?>

 <?php echo $paginator->sort('Name', 'name', array('title' => 'Sorting Title Alphabetically','class' => 'normalTip')); ?>

<?php foreach ($products as $product): ?>
 ...
<?php endforeach; ?>

Answer 1

To use the paginator class in your element, you must have to include the helper class in your controller. So your controller's code will looks like :

var $helpers = array('Html','Form','Ajax','Javascript', 'Text', 'Paginator');

More Explanation: "Fatal error: Call to a member function sort() on a non-object" comes when you are trying to access the method through an object which never been instantiated by any class. So your application must know which kind of object it is.

Kindly ask if it not worked.

Answer 2

It sounds like $paginator isn't set to anything.

If you put this code in your view, does it say $paginator is NULL?

var_dump($paginator);

It's hard to say from the code provided, but I assume you either

1. Aren't making $paginator available to your view in your controller
2. Are using the incorrect variable name altogether
