func myHandler(w http.ResponseWriter, r *http.Request) { name := r.FormValue("name") fmt.Fprintf(w, "Hello, %s!", name) }
func myHandler(w http.ResponseWriter, r *http.Request) { name := r.FormValue("name") age := r.FormValue("age") fmt.Fprintf(w, "Hello, %s! You are %s years old", name, age) }
func myHandler(w http.ResponseWriter, r *http.Request) { if r.Method == "POST" { name := r.FormValue("name") age := r.FormValue("age") // Do something with the form data... } // Render the HTML form... }This example shows how `FormValue` can be used to handle incoming POST requests. The function first checks that the request method is POST, then retrieves the form data using `FormValue`. Finally, it processes the data and returns a response. If the request method is not POST, the function simply renders an HTML form for the user to fill out. In all these examples, the `FormValue` function belongs to the `http.Request` struct, which is part of the `http` package library in Go.
