I have to set category id in cookie when customer go to Category page and update cookie with category id when visit again using seperate module.

I have created Observer and set cookie there but not working. I have checked Observer is calling and also getting correct category ID.

Issue is with Cache. if Cache is enabled all is working fine.

events.xml

<?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_controller_category_init_after">

 <observer name="cookieObserver" instance="VendorModuleObserverCategoryData" />

</event>

</config>

Observer - Data.php

<?php
namespace VendorModuleObserverCategory;

use MagentoFrameworkEventObserver;
use MagentoFrameworkEventObserverInterface;

use MagentoFrameworkStdlibCookieCookieMetadataFactory;
use MagentoFrameworkStdlibCookieManagerInterface;


class Data implements ObserverInterface


const COOKIE_NAME = 'categoryId';
const COOKIE_DURATION = 86400; // One day (86400 seconds)

protected $cookieManager;

/**
 * @var CookieMetadataFactory
 */
protected $cookieMetadataFactory;

public function __construct(
 CookieManagerInterface $cookieManager,
 CookieMetadataFactory $cookieMetadataFactory
)

 $this->cookieManager = $cookieManager;
 $this->cookieMetadataFactory = $cookieMetadataFactory;


/**

 * Below is the method that will fire whenever the event runs!

 *

 * @param Observer $observer

 */

public function execute(Observer $observer)

 $data = $observer->getData();
 $metadata = $this->cookieMetadataFactory->createPublicCookieMetadata()->setDuration(86400)->setPath('/');
 $this->cookieManager->setPublicCookie('categoryId', $data['category']->getId(), $metadata);

return $this;

Please provide some suggestion or help.

You can use event, observer to create/update/delete cookie when some visiting category page.

You can use the event catalog_controller_category_init_after or any other event like layout_load_before.

/* Set cookie */

$categoryId = 'Category ID'
$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$cookieManager = $objectManager->create('MagentoFrameworkStdlibCookieManagerInterface');
$cookieMetadataFactory = $objectManager->create('MagentoFrameworkStdlibCookieCookieMetadataFactory');
$metadata = $cookieMetadataFactory
 ->createPublicCookieMetadata()
 ->setDuration(1800)
 ->setPath('/');
$cookieManager->setPublicCookie(
 'categoryId',
 $categoryId,
 $metadata
);


/* Retrive the cookie values */

$cookieManager = $objectManager->create('MagentoFrameworkStdlibCookieManagerInterface');
$cookieValue = $cookieManager->getCookie('categoryId');

You can follow manual to create a custom extension
