Ok! Complete, incidentally, this cycle classification and display classification under the function of the product before Bo Master I found on the internet for a long time did not find, hence, simply self-developed. The most critical is the category.php inside of the Foreach loop, interested students can study to see. I hereby share it with my friend.
