   I have a site with a category structure that is large, deep, and dynamic. I want to use a category template based on a conditional statement that uses the current category depth level.

   I don't want to use is_category('13,14,15') because with hundreds of categories, that may be added and removed, I don't want to hard code every category ID in a certain level.

   In an ideal world, this would be my code (unfortunately there is no such conditional statement):

   <?php
   	if ( is_category_level('1') ) {
   		include(TEMPLATEPATH . '/category-level-1.php');
   	} elseif ( is_category_level('2') ) {
   		include(TEMPLATEPATH . '/category-level-2.php');
   	} elseif ( is_category_level('3') ) {
   		include(TEMPLATEPATH . '/category-level-3.php');
   	} else {
   		include(TEMPLATEPATH . '/category.php');
   	}
   ?>

   Here are two forum posts that might be similar: http://wordpress.org/support/topic/369287?replies=4, and http://wordpress.org/support/topic/338561?replies=8.

   Can anyone help me figure out how to specify the category template based on category level?

   Thank you!

   You might find the cat_is_ancestor_of useful.

   put this in your theme's functions.php
   

   function is_category_level($depth){
   $current_category = get_query_var('cat');
   $my_category  = get_categories('include='.$current_category);
   $cat_depth=0;
   
    if ($my_category[0]->category_parent == 0){
    	$cat_depth = 0;
    	} else {
   
    while( $my_category[0]->category_parent != 0 ) {
     $my_category = get_categories('include='.$my_category[0]->category_parent);
     $cat_depth++;
     }
     }
     if ($cat_depth == intval($depth)) { return true; }
     return null;
   }

   and use the function in category.php like this:
   

   <?php
   if(is_category_level('1')){
   	// do stuff
   }
    ?>

   is_category_level('0') = parent-category (not a sub-category)
   is_category_level('1') = a sub-category of a parent-category
   is_category_level('2') = sub-category of a sub-category of a parent-category
   etc.. etc..

   keesiemeijer,

   Thank you very much for the function. Unfortunately it always only returns level 0 no matter what level of category is visited. Is there something I need to change to recognize all levels?

   Thanks!

   I just copy pasted the code here on my server and it works. Are you using the function in category.php?

   keesiemeijer,

   After a bit of testing I found it only works when there is a post directly in the category. In my site structure the posts are only in the third-level category.

   Is there anything I can change in the function to make it work even if there is no post in the category?

   Thank you for your continued help!

   try changing these lines in the function:
   $my_category = get_categories('include='.$current_category);
   and
   $my_category = get_categories('include='.$my_category[0]->category_parent);

   to:
   $my_category = get_categories('hide_empty=0&include='.$current_category);
   and
   $my_category = get_categories('hide_empty=0&include='.$my_category[0]->category_parent);
