Tips on display categories in WP ecommerce

There are a few ways to enable WordPress e-commerce plugin to display categories. Some of them are not so obvious to be noticed. Well, you have to bear with that since it’s open source world, what can you expect more. Most of the time we have to dig into the code to figure things out. And I am hoping my finding will help someone else out there. My environment (Windows XP, WordPress 2.5.1 and WP e-commerce 3.6.6) may be different from yours, therefore, the tips here may not apply to yours and you have to use your own judgement, but you may still learn something useful here though. Keep on reading.

Tip #1: Add [showcategories] to your post or page wherever you want it to go, WordPress engine will figure out how to replace this by the corresponding product category list

Tip #2: Calling nzshpcrt_display_categories_groups() function directly. This function is defined in products_page.php. There are a few references to it in this release. Here are:

wp-e-commerce\products_page.php(45): function nzshpcrt_display_categories_groups() {
wp-e-commerce\products_page.php(101): echo nzshpcrt_display_categories_groups();
wp-e-commerce\products_page.php(167): echo nzshpcrt_display_categories_groups();
wp-e-commerce\wp-shopping-cart.php(2015): $output = nzshpcrt_display_categories_groups();

Line numbers may be off a bit, so in this case you will need to just look around. It should not be a big problem

Tip #3: Calling show_cats_brands() directly. Well, this is the core to showing categories. You definitely need to take a look at this function if your changes won’t work. This function is defined in show_cats_brands.php, and here is the signature:

function show_cats_brands($category_group = null , $display_method = null, $order_by = 'name')

  2. I used the [showcategories] on the products page. Except when I click the links directly on the page it comes up with a “Not Found” page. How can I fix this?

  4. this doesn’t work for me – adding [showcategories] produces this error, even when trying to save the page:

    Call to undefined function nzshpcrt_display_categories_groups()

    Calling it directly produces the same result and calling show_cats_brands() produces nothing. Am I missing something?

  5. Hey, Ikool,

    Not sure I quite know what to do with this function yet but I had been searching for where to find it for a couple of hours in the WP Ecomm forums and on Google. Thanks so much for the tip on where it is!

  7. I have the same problem as the previous poster. Also latest ecommerce and WP. I can’t assign my products to any categories.

    I happened to delete the lone default category, and now I can find no way to make any new categories, restore the default category, or assign products to categories.

    I have completed all my variations, payment gateway settings, lots of product additions etc., so I really don’t want to have to reinstall. Very frustrating. I cannot find any documentation on this anywhere online. Does anybody have advice? Thanks!
