Hi all,

I am trying to find out how forms are working in Drupal.

I actually need to create a form that when it is submitted redirect the values to an external link.
I am am able to do it with an html/php, But i do not know how to do it with Drupal.
I attach below both codes.

I will really appreciate anyone could point me in the right direction, even with an URL for a documentation. I looked in form API doc but probably I do not have the knowledge yet to understand it.
I am trying to learn.

Thanks to evryone
