What is the best method, if there is one, of using WordPress as a CMS for users to input data while not actually building the website on the WordPress platform?
One possible solution I’ve found is using a PHP class called “WPGet” (http://peter.upfold.org.uk/projects/wpget) which fetches directly from the database.
You could use WordPress’ API calls, but depending where your “custom built application” sits, it might require including numerous files in your code (not very fun/efficient)
