The wp-e-commerce shopping cart plugin lets you sort your products by a few different things: name (product title), price, date/time created… but it doesn’t let you sort by category name and then product title. Here’s what I just came up with for one client; it isn’t generic, but other developers should be able to adapt it for their circumstances.
I just stared in
horror wonder at the wp-e-commerce script that handles cart updates. Wow. Just… wow. Forget any thought of nicely hooking into that to add some extra client-side actions, it’s a mess and looks like it will probably get worse before it gets better. But fortunately, there is another way.
The wp-e-commerce shopping cart plugin is probably the most popular cart plugin for WordPress, but it isn’t always the most easily customised; in fact, theming it can be a nightmare. One little niggle I had to fix recently was that the notification emails don’t include relevant purchase information such as which shipping method was selected, or the per-item comments from the purchaser (e.g. a message to be included inside a book flap).
