Updated for 1.2 & 1.3: Adding category depth tag to Shopp

Problem: I needed to display sub categories of a category in category.php but only one level deep. Using:

<?php if(shopp('category','hascategories')): ?>
  <?php while(shopp('category','subcategories')): ?>
    //display stuff
  <?php endwhile; ?>
<?php endif; ?>

…displays all subcast AND their subcats.

Fix: I decided to add a new tag, called shopp(‘subcategory’, ‘depth’) that would return the category depth. That way in the loop above this would show only immediate children:

<?php if(shopp('category','hascategories')): ?>
  <?php while(shopp('category','subcategories')):
    $depth = shopp('subcategory', 'depth', 'return=true');
    if($depth!=0):
      continue;
    endif; ?>
   //else display stuff
<?php endwhile; ?>
<?php endif; ?>

Adding the new tag in Shopp 1.1: Open the theme’s functions.php file and add this:

add_filter('shopp_tag_category_depth','return_cat_depth',10, 3);
add_filter('shopp_tag_subcategory_depth','return_cat_depth',10, 3);
function return_cat_depth($result, $options, $Category) {
 return $Category->depth;
}

Adding the new tag in Shopp 1.2 and 1.3+: Open the theme’s functions.php file and add this:

add_filter('shopp_themeapi_collection_depth','lookup_my_depth',10, 3);
function lookup_my_depth ($result, $options, $Category) {
 $ancestors = get_ancestors($Category->id, 'shopp_category' );
 return(count($ancestors));
}

…once that’s added, shopp(‘subcategory’, ‘depth’) can be used anywhere in the Shopp templates.

So what would that 1.2 hook look like?

  This might be the latest reply ever… but I’ve just updated this with some code for the current version of Shopp 🙂
