WordPress类别查询不起作用

Question

I want to get the category from the current archive page with

<?php single_cat_title( '', true ); ?>

So i defined $thecat = single_cat_title( '', true );

and now I am trying only to echo something if the category isn't the current one.

<?php if($thecat !== "Stuff") { echo'<li><a href="/stuff"> Stuff</a></li>';}?>

But it is not working.. what is wrong here?

Answer 1

You're almost there.

Have a look at the manual page for single_cat_title() , you'll see that it takes two parameters. The first is a prefix to use in the return; the second is the important one here - it defines whether you want the category to be echoed out (if true ), or returned (if false ). So all you need to do is swap:

$thecat = single_cat_title( '', true );

to:

$thecat = single_cat_title( '', false );

In your current code, you're just echoing the title, and $thecat is being set to null .
