So here's what I'm trying to do. I'm building a plugin for a business directory. Each business is assigned to a category. There are two views, listing and detail. To give the user as much flexibility as possible, I have created a shortcode where they can pass in the category and that will display the listview. This works great. They can create a page, called "Fishing" with a permalink of "/fly-fishing" and the content is
Here's some title information about our fishing. Thanks yadda yadda. [business-directory category=fishing]
Notice that the category and the permalink are different. Again, to show the flexibility I'm trying to achieve.
In my listings, I would like a permalink to each business that uses the permalink of the category page that they select. So one might be /fly-fishing/abc-fishing. When that permalink is visited, I need my plugin to know that the category is actually fishing and the business is abc-fishing.
I'm having trouble with creating the add_rewrite_rule such that it knows what page to pass back to. My thought was to query each page, look for my shortcode, and then add the rewrite_rules accordingly. This means I will have to do this on every page creating/update.
Is there a better way?
