I am working on a plugin (widget) that is using some transients that are updated from time to time.

That said, when these transients are updated, I think I will need to flush the cache to display the new data properly.

Thus, I wonder if have some way to flush the cache only for widget instead of entire cache. Do you guys have some advice?

if you want to flush the specific cache you can do that: the plugin has functions for that

flush_pgcache();  // Page cache
flush_dbcache();  // Database cache
flush_minify();  // Minify cache
flush_all(); // All caches

and you just need to call it like this:

    Hey, thanks for your reply. However I was not planning to flush entire cache. I wonder if is possible to flush just the widget area. Do you have any ideas? Jan 8, 2014 at 19:11
  • There was no option/function available to flush widget cache. You have to flush_pgcache(); or flush_dbcache(); based your needs.

  • Hey, looks like it is possible to do what I need using Fragment Caching :) Thanks for the help! Jan 26, 2014 at 5:16
