I am trying to automatically add the current year to the meta title and description in for example category-pages. I want to achieve something like this:

Meta title: "The best category items for {{year}}" >> "The best category items for 2019"

What would be the easiest way to do this?

  • for a particular category or all categories? – Amit Bera Jun 3 at 12:59
  • For all categories in which the {{year}} tag is used. I just want to replace this tag with the current year. – klaaskox Jun 3 at 13:11

In this case, you can use event/observer.

Fire an observer on the event catalog_category_load_after at frontend area set meta description on the fly.

Create events.xml at app/code/StackExchange/Magento/etc/frontend/ and as `events.xml location under on frontend and this event only fire for frontend area.

events.xml code

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="catalog_category_load_after">
        <observer instance="StackExchange\Magento\Observer\Frontend\Catalog\CategoryLoadAfter" 

Create Observer class CategoryLoadAfter at app/code/StackExchange/Magento/Observer/Frontend/Catalog/.

CategoryLoadAfter.php code

namespace StackExchange\Magento\Observer\Frontend\Catalog;

class CategoryLoadAfter implements \Magento\Framework\Event\ObserverInterface {

     * @var \Psr\Log\LoggerInterface
    private $logger;

    public function __construct(
     \Psr\Log\LoggerInterface $logger
    ) {

        $this->logger = $logger;
     * Execute observer
     * @param \Magento\Framework\Event\Observer $observer
     * @return void
    public function execute(
        \Magento\Framework\Event\Observer $observer
    ) {
        $category = $observer->getEvent()->getCategory();
        if ($category instanceof \Magento\Catalog\Model\Category) {
            $oldMetaTitle = $category->getMetaTitle();
            $oldMetaDescription = $category->getMetaDescription();
            $oldMetaKeyword = $category->getMetaKeywords();


Also, your module must have:

  1. app/code/{Vendor}/{Modulename}/etc/module.xml
  2. app/code/{Vendor}/{Modulename}/composer.json
  3. app/code/{Vendor}/{Modulename}/registration.php

After adding the event you should flush the cache.
