Show User’s Displayed Name

You mean like someone logged in?

<?php
setup_userdata();
echo 'Howdy '. $user_identity . $user_ID	;
// print_r($userdata); uncomment this to show whole array of userdata
 ?>

Yes! But can I put the $user_ID in a link? Such as “/members?user=$user_ID”?

Like
'?author=' . $user_ID;

Like, I have a members page. There’s a link /members?user=username
Can I have in a link /members?user= then your username, like <a href="/members?user=$user_ID">Your Profile</a>, and if so how?

If you are using a membership plugin of some sort please let us know which one you are using.

I’m using “Profiler”

Can someone please help?

I’m sorry, what more do you need?

How can I create a “Your Profile” link with Profiler? It’ll take you to YOUR profile if your logged in. A universal link.
