I am use to php development in general and I am use to getting a lot done by making a
POST to a php file. However I have not seen people using
$_POST in WordPress. I have seen one discussion about someone wanting to create new posts on their blog using
$_POST, and they were directed to a more secure system. (Perhaps I misunderstood the conversation though.)
I would still like to use
$_POST simply as a part of the user interface.
If it is possible and not a horrible idea to use $_POST what do I need to know to make $_POST work well with WordPress? Are there rules about making a $_POST, or how redirecting so that nothing interferes with WordPress behavior? Are there any other special considerations?
