Reset to default 0You have to call TopAuthor()
function in plugins_loaded
orinit
action. You are getting Fatal error: Uncaught Error: Call to undefined function wp_get_current_user()
because wp_get_current_user()
is a pluggable function. You can not call when your plugin is included. You have to wait for the action plugins_loaded
or init
. Call your TopAuthor()
function using init
or plugins_loaded
action.
init action:
add_action('init','do_stuff');
plugins_loaded action:
add_action('plugins_loaded','do_stuff');
Your function :
function do_stuff()
{
TopAuthor();
}
So full code of Your Plugin file look like:

TopAuthor
function gets immediatley executed on all page requests, REST API endpoints, AJAX requests, etc, in which case you can't do that, some API calls have to happen after certain events have fired, you're calling them before they're ready – Tom J Nowell ♦ Commented Dec 30, 2019 at 23:35TopAuthor
rather than calling it in a template or adding it as a shortcode? Even without the fatal error, your code would break so many other things as is – Tom J Nowell ♦ Commented Dec 31, 2019 at 0:11
