I need a way to obtain some user input from a post.
e.g. I have a post is about a home to rent. I need something like an input field, associated with that post ID, so users can make a reservation to a certain date. This date would be associated to the post in any manner, like a custom field or something.
But even simpler i need to know how can a user can fill an input field in a post, with information that somehow will be written in the DB associated with that post.
Can someone help, please?
