Exclude parent categories from the_category() within the loop

Question

I have typical parent and child categories setup as follows:

• Food
  • potatoes
  • corn
  • beats
• Sports
  • soccer
  • football
  • hockey

etc.

In my index.php template I'd like to list the categories of the specific post. The problem is, when I use the_category() it lists the parent categories twice. I'm using the following code:

<php echo '<dt>', the_category(', ', 'multiple'), '</dt>', "\n"; ?>

And it prints out:

Food:corn, Food, Food:potatoes

I believe it is listing the child category "corn" as "Food: corn" followed by the parent category "Food" just as "Food." Is there a way to exclude the parent categories?

The way I'd like it to read is:

Food:corn, Food:potatoes

Thank you.

Answer 1

Have you tagged the post in Food, Food:Corn, and Food:potatoes? Try categorizing it in Food:corn and Food:potatoes only.

I do not believe that there is a means to exclude categories from the_category() function. You will have to use another function to create a custom query to do so.

Try some of these.
