If you keep the actual SQL and the export format separate you can: create a new exporter for another table structure easily use … Read more
You actually have several questions in there, so I’ll answer them one by one: However, if I simply do this on my main plugin file, it doesn’t work: add_filter(‘pre_set_site_transient_update_plugins’, array(‘XYZ’, ‘check_update’)); First of all, I’d like to understand what’s the difference between the two scenarios. This is failing because you are calling the method statically, … Read more
This is not possible the way you think. It would maybe be possible if you use Reflections or debug_backtrace(), but there’s no reliable way to do this. WordPress does not keep a stack or queue where it tracks file names. The only thing I could imagine is just hooking into the action and inside wp_enqueue_scripts(): … Read more

The query vars filter is unnecessary for what you’re doing here, as you’re not using it in a query. Adding it to the URL as a GET parameter will not make it appear in the array of query vars, as there’s no mechanism that converts a GET var to a query var, you’ve only ensured … Read more
I was having this same issue and was able to correct it by expanding on Andy’s solution, however I only needed to force on value in particular to not use W3TC’s object cache. I tried using APC, Memcached as well as Disk for the cache with the same results. Caching certainly helps performance, and the … Read more
The sweet and short is to not break your head over naming conventions or consistency in WordPress, as these are non existant “standards”. To be really honest, WordPress does not follow any fixed set of rules or standards, even though there is a handbook on coding standard available for WordPress developers.

It’s possible to use the get_template_part_{$slug} action hook to inject template parts, however, without any change to your theme or a child theme, the original template part will be added anyway.
