After fooling with WordPress’s wp_list_categories function to list categories, I realized that it only allowed you to display categories as a list or delimited by a <br>. So after looking around on Google to no avail, I decided to whip up a function that allows for different delimiters. The function is fairly simple with one argument for the string of the delimiter.

Calling the Function

In my theme folder I have a file called functions.php that gets loaded when the theme is loaded. If your theme doesn’t have one you can create one. Copy and paste this function into the functions.php file. Now all you have to do is call the function in the theme template where you want your category links to show up.


<?php echo delimited_cat(); ?>

You can also pass the function an argument and change the default “, ” delimiter to anything you like. The example below would delimit by a pipe with spaces on both sides.


<?php echo delimited_cat(' | '); ?>

Uses this code at your own risk.
