Those strings are run through translation functions (as in __() _e() _x() etc.). This means you can use the “gettext” filter to alter it in ways besides translations. Have your callback check for a match. When it occurs, return the alternative value. Your callback needs to be as efficient as possible. gettext() gets called many times on a typical page.
Thanks @bcworkz for your help, I got it to work:
add_filter('gettext', 'changeTaxonomyLabels');
function changeTaxonomyLabels($translated_text) {
global $taxonomy;
if (is_admin() && $taxonomy == 'artists') {
switch ($translated_text) {
case 'The description is not prominent by default; however, some themes may show it.':
$translated_text = __('A short description about the artist.');
break;
}
} return $translated_text;
}
How to function works:
First off we get the global $taxonomy variable, so we can check it later. Then we make sure that the current user is an admin, and that the current page is one of our taxonomy (which is called artists). We replace the default text (the case) with our custom text (‘A short description about the artist’) by changing the $translated_text variable. And finally, return the updated variable.
