render elements in cakephp on home.ctp - cakephp

Question

I am using cakephp 2.4
in my apps I have a view in CategoriesController namely "Editorial" and I can show all the articles under that category by http://mydomain/categories/editorial
I am trying to show all the articles under "Editorial" category in the home.ctp by echo $this->element('editorials');
but it shows Notice (8): Undefined variable: articles [APP\View\Elements\Editorials.ctp, line 4]
CategoriesController.php
public function Editorial() {
$category = $this->Category->find('first', array(
'conditions' => array(
'Category.id' => 1
)
));
$this->set(compact('category'));
$this->Paginator = $this->Components->load('Paginator');
$this->Paginator->settings = array(
'Article' => array(
'recursive' => -1,
'contain' => array(
'Category'
),
'limit' => 5,
'conditions' => array(
'Article.category_id' => $category['Category']['id'],
),
'order' => array(
'Article.id' => 'ASC'
),
'paramType' => 'querystring',
)
);
$articles = $this->Paginator->paginate($this->Category->Article);
$this->set(compact('articles'));
}
View file:
<?php if (!empty($articles)): ?>
<?php echo $this->element('editorials'); ?>
<?php echo $this->element('pagination-counter'); ?>
<?php echo $this->element('pagination'); ?>
<?php endif; ?>
Elements/Editorials.ctp:
<div class="row">
<?php
$i = 0;
foreach ($articles as $art):
$i++;
if (($i % 4) == 0) { echo "\n<div class=\"row\">\n\n";}
?>
<div class="col col-sm-3">
<?php echo $this->Html->link($art['Article']['title'], array('controller' => 'articles', 'action' => 'view', 'id' => $art['Article']['id'])); ?>
<br />
</div>
<?php
if (($i % 4) == 0) { echo "\n</div>\n\n";}
endforeach;
?>
<br />
<br />
</div>

Answer 1

try to add $this->render('file'); in your Editorial action and replace file with view file name without.ctp

Answer 2

Something you can change:
1. In controller:
$this->set(compact('category', 'articles')); // one set()
2. In view: (Main Point)
<?php echo $this->element('editorials', array('articles' => $articles)); ?>
Here, you need to pass the articles variable to element like above, by default an element don't recognize the viewVars.
