Get Page Title > If No Page Title > Get Category Title

Hi there,

Something I have been struggling with for a while as I am a novice. On every page I have an instruction to GET Page Title:

<?php echo get_the_title( $ID ); ?>

However as some of my pages are Categories when you are on this page it returns “Untitled”.

What I would like to do is one piece of code which GET Page Title but if there’s no page title get category title instead else do nothing, output blank, “”.

I know how to get category title:

<?php single_cat_title(); ?>

However I cannot combine the two to achieve what I need.

Any help would be much appreciated.

Cheers,

James
