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

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.

No. You have to use wp_options, because you can’t create new fields in the wp_term_taxonomy table (If you do, in the next WP update you’ll loose them). So: // the option name define(‘MY_CATEGORY_FIELDS’, ‘my_category_fields_option’); // your fields (the form) add_filter(‘edit_category_form’, ‘my_category_fields’); function my_category_fields($tag) { $tag_extra_fields = get_option(MY_CATEGORY_FIELDS); ?> <table class=”form-table”> <tr class=”form-field”> <th scope=”row” valign=”top”><label … Read more
Use the filter ‘mce_external_languages’. From wp-includes/class-wp-editor.php: The following filter loads external language files for TinyMCE plugins. It takes an associative array ‘plugin_name’ => ‘path’, where path is the include path to the file. The language file should follow the same format as /tinymce/langs/wp-langs.php and should define a variable $strings that holds all translated strings. When … Read more
