krsort error | WordPress.org

Hi @gaurav1980,
I am not sure how this function is called (which hook and priority), but it appears to be executed before the $permalink_manager_uris global is populated with data. Because the variable’s value is null, ksort() returns an error.

You should keep two things in mind:

1. Make sure the variable is indeed an array before trying to sort it
2. Make sure that your code is called after the $permalink_manager_uris variable is filled with data

The “plugins_loaded” hook with priority 10 is the first time you can run the sorting function.

//* Permalink Manager Required
function pm_custom_uris_order() {
	global $permalink_manager_uris;

	if(is_array($permalink_manager_uris)) {
		krsort($permalink_manager_uris);
	}
}
add_action('plugins_loaded', 'pm_custom_uris_order', 10);

Best regards,
Maciej
