Get form post value in Go

Practically almost every web page out there will ask you to fill a form to progress further. Most of these forms will post data to the server for further processing. Go has the capability to capture the posted form data as well. In this tutorial, we will show a simple function to capture the posted form data with

r.FormValue("form_data") function

In the client browser:

 <form action="http://website/process_form_data" method="post">
 <input type="text" name="form_data" id="form_data" >
 </form>

At the Go server :

 func process_form_data(w http.ResponseWriter, r *http.Request)  {
  if r.Method == "POST" {
 form_data := r.FormValue("form_data")
 }
 }
