Let’s see how we can Invalidate and Flush Custom Cache? We have created a custom cache type https://sbdevblog.com/magento-2-how-to-create-custom-cache/ as well as we have saved and retrieved data from the cache https://sbdevblog.com/magento-2-store-retrieve-from-the-custom-cache/
Invalidate and Flush Custom Cache?
Sometimes we require to invalidate the cache on a certain event like blog creation. Let’s see how can we invalidate that cache using code.
We require to use Magento\Framework\App\Cache\TypeListInterface in order to Invalidate or Flush the cache type.
<?php
/**
* @copyright Copyright (c) sbdevblog (https://www.sbdevblog.com)
*/
namespace SbDevBlog\Cache\Services;
use Magento\Framework\App\Cache\TypeListInterface;
class InvalidateAndFlushCustomCache
{
/**
* @var TypeListInterface
*/
private TypeListInterface $typeList;
public function __construct(
TypeListInterface $typeList
){
$this->typeList = $typeList;
}
/**
* Invalidate cache
*
* @param array $type
* @return void
*/
public function invalidateCache(array $type):void
{
$this->typeList->invalidate($type);
}
}Let’s flush the custom cache type
<?php
/**
* @copyright Copyright (c) sbdevblog (https://www.sbdevblog.com)
*/
namespace SbDevBlog\Cache\Services;
use Magento\Framework\App\Cache\TypeListInterface;
class InvalidateAndFlushCustomCache
{
/**
* @var TypeListInterface
*/
private TypeListInterface $typeList;
public function __construct(
TypeListInterface $typeList
){
$this->typeList = $typeList;
}
/**
* Flush cache by Type
*
* @param string $type
* @return void
*/
public function flushCache(string $type):void
{
$this->typeList->cleanType($type);
}
}That’s the simple way to invalidate as well as flush any type of cache. Thanks for reading SbDevBlog. Please use the comment box for your feedback.
