Handling form request from plugin file

In a plugin I have a payment form that needs to be submitted (via the action= attribute) to a .php file, also located in my plugin directly.

Using database meta_values to calculate new post order using pre_get_posts or a 'request' hook

UPDATE: I have worked out my implementation of the selected answer at the bottom of this post.
