Web form customization and submit action redirect to custom php code.

Hi,

I am developing a website for internal work flow in my organization.
I am not sure how to proceed, customization seems very complicated to me.

I tried hands on adding custom page, php code, but i m not sure how to
redirect webform to a custom php page.

Please consider me a newbie.

My requirements are:

1. Create a web form. ( with a text and a submit button)
2. get the value of web form text field.
3. process the value through a internal command running on server,
display the output.


Could you please help me out with these.



Thanks and regards,
Rohit Sharma
