Magento 2: How to add class "paginated" to the body tag if the products are paginated?

Question

I am working on a Magento 2.1.7 shop and I have created a child-theme of Magento Blank.

I need to add class "paginated" to the body tag if the products category pages display pagination.

I have copied the pager.phtml file to app/design/frontend/Company/Theme/Magento_Theme/templates/html/, so that I can safely overwrite the defaults.

In this file, there is an if statement that "decides" when the pagination is displayed:

<?php if ($block->getLastPageNum()>1): ?>
 // Pagination code here
<?php endif; ?>

Is there anything I can add inside this if statement that would add class "paginated" to the body tag?

Answer 1

If you have access of block class then you can do it like this,

use Magento\Framework\View\Page\Config as PageConfig;

protected $pageConfig;


public function __construct(
    ...
    pageConfig $pageConfig
    ....
) {
    ....
    $this->pageConfig = $pageConfig;
    ....
}

Now you can use this like,

$this->pageConfig->addBodyClass('test');

---

If you don't have access of block class then you can do it by objectManager (not recommended)

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$pageConfig=$objectManager->create('Magento\Framework\View\Page\Config');
$pageConfig->addBodyClass('test');

There is a better solution to the problem this question is trying to solve: Do not display a “per page” select box, if products are not paginated.
