I'm building a plugin to browse store orders via a third-party API. I make various requests to URLs that can include query parameters:

  • /customers
  • /orders/e8b48e72-9c7f-4d6f-91aa-2f7238bdf936
  • /orders?offset=0&limit=250&from=2014-05-26T22%3A58%3A38%2B00%3A00&to=2014-06-26T22%3A58%3A38%2B00%3A00

I've just started using Guzzle and more importantly craft()->fileCache to keep results around for a few minutes and speed up browsing. I use the query URI as the key for the cache:

 craft()->fileCache->set($query, $response->getBody(true), 600); // store result for 10 minutes

A web hook gets hit with every new order that comes in, making it an ideal time to clear out these caches I've set—but I have no idea how.

Is there any way I can tag this plugin's caches or somehow clear out only those I've made, rather than get overzealous with craft()->fileCache->flushValues()?

You can delete a cache as follows:

craft()->fileCache->delete($key);

So instead of caching individual keys, you could perhaps cache an array of keys and delete the entire array when you want to clear out your keys.

  • Thanks Ben! An array of keys seems to make way more sense. – Matt Stein Jun 27 '14 at 13:23
  • glad you agree! – Ben Croker Jun 27 '14 at 15:44
  • You've given me the concept of a multi-dimensional cache and Guzzle this week. I can't even imagine what next week has in store. – Matt Stein Jun 27 '14 at 16:43
  • Has craft()->fileCache has been updated to just craft()->cache? – Ben Parizek Feb 9 '15 at 3:30
  • No, it is one of the available caching methods: buildwithcraft.com/classreference/etc/cache/FileCache – Ben Croker Feb 9 '15 at 9:18
