How can I retrieve the current URL (whether homepage, archive, post type archive, category archive, etc) but always without the /page/{pagenum}/ part if it’s present? So, if the real URL is:
example.com/category/uncategorized/
OR
example.com/category/uncategorized/page/2/
then the return value will always be
example.com/category/uncategorized/
You can get the current URL through home_url( $wp->request ).
Try the example below:
global $wp;
// get current url with query string.
$current_url = home_url( $wp->request );
// get the position where '/page.. ' text start.
$pos = strpos($current_url , '/page');
// remove string from the specific postion
$finalurl = substr($current_url,0,$pos);
echo $finalurl;
