Version 0.1;
The is the project page for the ZenTagCloud. Its in development right now, its open source and I'd love input / contributions.
Note: the current version is not recommended for live online stores (where you have something to loose), however by all means try it out on you test site, have a look at the code and give me feedback.
p.s. Don't hold me responsible if something breaks.
What is a Tag Cloud?
A tag cloud (or weighted list in visual design) can be used as a visual depiction of content tags used on a website. Often, more frequently used tags are depicted in a larger font or otherwise emphasized, while the displayed order is generally alphabetical. Thus both finding a tag by alphabet and by popularity is possible. Selecting a single tag within a tag cloud will generally lead to a collection of items that are associated with that tag.
Features:
2/June/07: Displays category titles with random weights
3/June/07: Tags links to you Zen Cart site category pages.
Install:
1. Copy the code from this file to one of the Defined Pages using: Tools > Defined Pages Editor.
2. Ensure that the Defined Pages module is enables under: Tools > Layout Box Controller
3. Visit your site, and go to the defined page you pasted the code into. You should see a list of your sites categorie, with random sizes assigned to each one.
Todo/Wishlist:
- Save weights to database
- Add code to ?category's page? so that visits to category's changes weights
- Incorporate some noise in the category's weights to enable new category's a fair chance.
- Option to read tags from meta data
- Option to weight tags my relevance to current tag. (If you like a, you might like b type of thing)
With some code from:
- Derek Harvey (
www.derekharvey.co.uk)
- Zen Cart Team (
www.zen-cart.com)
Security Note: I've copied and modified a zen cart function to retrieve data from the db, and I think that by leaving the function embeded with the code if may pose some security risk. I'm open to advice on where to put it for best security practice.
