Guys what does it mean when the action attribute of a form is set this way.

Question

<form action="./" method ="post">

What is the ./ used for ?

Answer 1

The action attribute is using relative path, "./" refers to current directory/folder, "../" refers to a directory on a higher level of hierarchy (parent directory). Read about relative and absolute path in the following link:

Answer 2

that is to say the form is submitted to it self for processing right?

Answer 3

I cannot tell for sure mate, for all I know, if you're submitting form data to the same file for processing, usually it is left as empty string, or omitted. However, if the file is named 'default' or 'index' it will most likely be the default filename used for current directory, appointed by './' attribute.

Have you verified if such setting routes the data back to the file? maybe make a test file for that reason.
