I want my wordpress category.php template to be able to detect whether the category it is serving is a parent category or subcategory. THATS IT. And without having to hard code any category ID’s. After perusing the forums and codex for a couple of hours, the marriage of these two functions seemed to get the job done.

get_query_var is the variable stored in the query that tells category.php what category to serve.

get_category retrieves category data given a category ID or category object.

Here’s the function that goes in your functions.php file:

function is_subcategory (){
    $cat = get_query_var('cat');
    $category = get_category($cat);
    return ( $category->parent == '0' ) ? true : false;
}

Then you can use this in your category.php file to determine if the category you are serving is a parent category or subcategory:

if ( is_subcategory() ):
     //displaying subcategory
else:
    //displaying parent category
endif;

Hope this helps some people out there.

*note: both code snippets should be wrapped inside php brackets. <?php ?>

I’m very excited to say that I will be attending WordCamp NYC 2009. I have been working with WordPress for the past two years and it has completely revoltuionized the way I design web sites.

If it weren’t for WordPress, I wouldn’t lead the life I live today. But that aside, its exciting to participate in such an awesome community. I look forward to meeting fellow WordPress users and abusers.

I’m just testing out the new WordPress Blackberry Application.  I must say so far so good, and just in time for my summer vacation to Europe…
