WP e-Commerce: The homepage does not show custom taxonomies

I add a product classification “PC” and “Phone”.

Now, I need to “PC” and “Phone” in the home page of the site show the two classifications of products.
I hope it is this:
1: “phomedia Product Specials Widget” only display products classified in the “PC”.
2: “Phomedia Latest Products Widget” only display products classified in the “Phone”.

How do I go to modify:
wpsclatestwidget.php, wpscspecialsdwidget.php these two documents? ? ?
wpsclatestwidget.php code：https://pastebin.com/2WgqDKQv
wpscspecialsdwidget.php code：https://pastebin.com/7eetQYjs

Please provide the complete modification tutorials and code. Thank you!
