   Hi,

   There's this line of code in a theme I bought:

   <div class="category"><?php the_category(', ') ?></div>

   It shows all of the categories a post is related to at the homepage and some other pages.

   There are two top categories (tag_ID=36 and tag_ID=15). A post never belongs to a top category but to multiple sub-categories that are under these 2 main categories.

   I'd like php the_category to show only sub-categories which their parent is not 36 (exclude).
   Or alternatively, show only sub-categories their parent is 15.

   How can I do it ?

   Thanks !

   write your own code based on get_the_category() http://codex.wordpress.org/Function_Reference/get_the_category, and use conditional tags to exclude categories from the foreach loop needed to create the output.

   If only I knew how.. :)

   Unfortunately I'm not a coder. That's why I'm asking...

   try to add this code to functions.php:

   http://pastebin.com/ZfMAuTTU

   no need to edit any other files.

   just be aware that it is quite specialized and not flexible - if the only category of the post is from a child of cat 36, it will show empty.

   make a backup copy of functions.php before editing in case you want to undo the edit.

   Thanks for the help!

   I get this error:

   Fatal error: Call to undefined function add_filter() in /home/getwebho/public_html/wp-includes/functions.php on line 4555

   you edited the wrong functions.php file - you need to add the code to functions.php of your theme

   located somewhere here:

   /wp-content/themes/yourtheme/functions.php

   Hi, I used the code in the pastebin below and it works perfectly on the site. In the admin, however, if you go to edit a post the category list is broken in an odd way there. It's showing up as HTML link code next to each checkbox, duplicated multiple times.

   Is there any way to block this function from affecting the admin?

   Thanks!
