   In my single.php file I am trying to list all the child categories under a specific parent category. I'm using the following code:

   if(!function_exists('subcat')){
   	function subcat(){
   		global $post;
   foreach((get_the_category()) as $category)
   {
       if ($category->category_parent == "177")
       {
           echo '<a href="' . get_category_link($category->cat_ID) . '">' . $category->cat_name . '</a>';
       }
   }
   	}
   }

   The code works, but in instances where there are multiple subcategories I would like to separate those subcategories with a comma. How do I do that? Anyone know?

   This should work:

   replace this
   if ($category->category_parent == "177")

   with this
   

   $cats = array(177, 213, 309);
   if ( in_array( $category->category_parent, $cats ) ) {

   if you have one category you can either use
   if ($category->category_parent == "177")
   or
   

   $cats = array(177);
   if ( in_array( $category->category_parent, $cats ) ) {

   Thank you. I actually figured out an alternative using css. :)
