I am trying to build a simple, two-Handler web server. In the first handler, I am pulling values from two fields, a user's first name and last name. In the second handler I am simply stating, "Hello" (first name, last name).
I've put an fmt.Println, and it seems that I'm not correctly pulling the info from the first Handler back into the Go programming. Where is this going wrong?
package main
import (
"fmt"
"html/template"
"log"
"net/http"
)
type Field struct {
Firstname string
Secondname string
}
func RootHandler(w http.ResponseWriter, r *http.Request) {
tmpl, err := template.ParseFiles("index.html")
if err != nil {
fmt.Println("Index Template Parse Error: ", err)
}
err = tmpl.Execute(w, nil)
if err != nil {
fmt.Println("Index Template Execution Error: ", err)
}
}
func main() {
http.HandleFunc("/", RootHandler) // sets router
http.HandleFunc("/welcome", WelcomeHandler)
err := http.ListenAndServe(":4000", nil) // set listen port
if err != nil {
log.Fatal("ListenAndServe: ", err)
}
}
func WelcomeHandler(w http.ResponseWriter, r *http.Request) {
Firstname := r.FormValue("Namef")
Secondname := r.FormValue("Namel")
fmt.Println(Firstname)
f := new(Field)
f.Firstname = Firstname
f.Secondname = Secondname
fmt.Println(*f)
tmpl, err := template.ParseFiles("tmpl/welcome.tmpl")
if err != nil {
fmt.Println("Index Template Parse Error: ", err)
}
err = tmpl.Execute(w, &f)
if err != nil {
fmt.Println("Index Template Execution Error: ", err)
}
}
And here is the index.html that I'm pulling the two values from:
<!DOCTYPE html>
<html>
<body>
<form action="/welcome" method="post">
<p> Welcome! First I will need your full name: </p>
First Name: <input type="text" id="Namef" name="FirstName"><br>
Last Name: <input type="text" id="Namel" name="LastName" ><br>
<input type="submit" value="Next">
</form>
<p>Click the "Submit" button and the form-data will be sent to a page on the server called "demo_form.asp".</p>
</body>
</html>
