Am I right to assume that action basically points the submission to a set of instructions (or site) when dealing with php or something as such?

Yes, action is describing where the form data is going. A form can submit the page it is on even. If the form action is empty like what you have in your title, or just isn't there, the form should default back to page it is on. You could have PHP code on that same page that handles a form submit. These backend languages will have ways of checking for form submits and ways to extract and handle the data.
It points to a server-side script that processes the contents of the form: validates the information, inserts it into a database, redirects to another page, etc.
It (the file referenced in the action="") can be written in a variety of languages/scripts PHP, ASP, Java, etc.

Hi Paul, the action attribute indicate where you form data will go. What file will receive the data and and work on it.
