Clear media search cache

Right. That answer was equally useful as no answer at all, thanks for that.

I’m writing themes and plugins for wordpress since 2.2. I think I have left the ‘Getting started’ part behind a while ago.

If you can’t provide proactive and helpful answers, I recommend you don’t.

Of course not. There are no files called wordpress-screenshots-x. This was an example to illustrate the behaviour.

However, I came to the conclusion it is not wordpress caching the search results, it is the browser (Firefox 26 in my case). It looks to me like the WordPress AJAX wrapper for the jQuery .ajax() function does use the default value for the setting cache, which is set to true. The search results are therefor being cached in the browser cache like every other web page as well. Unfortunately without the possibility to press F5.

Looks like there is no way I could change this behaviour other than editing the corresponding files in wp-includes/. Which I of course don’t want to get on with.

It would be nice to have some kind of refresh button in the media uploader – clicking on it could perform an ajax request with cache set to false – and would therefor update the search results.

Maybe I can find a way round to perform this using a plugin hook. Let’s see.

32	        // wp.ajax
33	        // ------
34	        //
35	        // Tools for sending ajax requests with JSON responses and built in error handling.
36	        // Mirrors and wraps jQuery's ajax APIs.

Line 32.

This class is being used for sending AJAX requests in the media browser/uploader. It is a wrapper for the jQuery .ajax() function: wp.ajax.send() calls $.ajax().

Please be so kind and read my posts.

I found out the Webbrowser caches the ajax results. Not wordpress.

WordPress could avoid that caching by setting the ‘cache‘ setting in the jQuery ajax call to false. That would probably solve it, but increase the traffic.
