forms html action

Question

When I have a form like this:

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

What does the "." in action stand for?

Answer 1

The action attributes tell the form where to post the form data to.

. Stands for current directory, so I would say this posts to the default document in the current directory.

There are several notations for relative paths:

• .. stands for parent directory
• . stands for current directory
• / stands for root directory if the URI starts with it
• / stands for child directory if the URI does not start with it
