Set cookie lifetime in phtml

Question

I want to set the cookie lifetime in my phtml file.

I am using the following code:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$cookieManager = $objectManager->get('Magento\Framework\Stdlib\CookieManagerInterface');
$cookieMetadataFactory = \Magento\Framework\Stdlib\Cookie\CookieMetadataFactory::getInstance();
$cookie_lifetime = (90 * 60);//90 days
$cookie_metadata = $cookieMetadataFactory->createPublicCookieMetadata()->setDuration($cookie_lifetime); 
$cookieManager->setPublicCookie('cookie1', 'value', $cookie_metadata);

I get this error:

Call to undefined method Magento\Framework\Stdlib\Cookie\CookieMetadataFactory::getInstance()

So, is there no getInstance method? What can I use instead?

Answer 1

You cannot directly get instance for Magento\Framework\Stdlib\Cookie\CookieMetadataFactory instead use

$cookieMetadataFactory = $objectManager->get("Magento\Framework\Stdlib\Cookie\CookieMetadataFactory");

However, you should probably using dependency injection of your constructor if you are in block or controller, make a function in block in case of phtml as objectmanager is not a recommended practice.
