This can be a simple vale or a more complex array. $data - The second parameter is just the data you want to cache.This will be used later to read the cache data back out. $cacheId - This is s string that is used to identify the cache data in your cache system.Let's go through the parameters a little. \Drupal::cache()->set($cacheId, $data, Cache::PERMANENT, $cacheTags) This takes a few parameters and is called like this. The first method to talk about is the set() method, which is used to write some cache to the cache system. Once you have a cache object, there are a couple of important methods you can use. By default, this will assume that you want to use the 'default' cache bin, which is essentially the cache_default table (assuming you are using the database for your cache storage). To get an instance of the cache system you can use the \Drupal::cache() method, which will return an instance of a CacheBackendInterface type object. If the data doesn't change much it might be better to add a cache to the request so that instead of going to the slow API the fast cache systems are used instead. The result of the function can be stored in the Drupal cache system just like other cache data.įor example, let's say you are pulling data from a slow API.
This is beneficial if you have an expensive function that takes a long time to complete. Whilst all of these mechanisms are really useful you can also inject data directly into the cache system. Not sure if this has been reported before, and not sure if anyone has had this before.The cache system in Drupal has a number of different components with time, contexts and tags being used to determine the cache.
