Magento is a shopping cart script that I do not recommend under any circumstances.
Below is an image showing the magento database structure.
Now imagine what it must be like to code a magento plugin.
It is over 1 million lines of code, it crashes on shared hosting so you have to run it on a VPS, and the database structure is complex, so just imagine what coding a plugin for it is like! The search feature did not work on a fresh install and the documentation isn't explanatory. The support on the official magento forums is abysmal.
I made a Brands plugin so products could be assigned to brands, brands could be browsed and was visible on the product page , search results, category page and search results, and you could filter by brand.
I also made a Showdown plugin where 2 products were chosen at random in a match, and the general public had to vote for which product they liked the best. A new match happened every day.
As I made 2 Magento plugins, I should be able to make a plugin for any shopping cart or CMS. With Wordpress, most plugins cost $50, $100 maximum, but I've seen Magento plugins that cost $800, so you need real programming talent to make a Magento plugin. It's not simple.
