Go provides html/templateparsing of html template files, converting the input submitted by the template files into structures and rendering them.
package main
import (
"html/template"
"net/http"
)
type ContactDetails struct {
Email string
Subject string
Message string
}
func main() {
tmpl := template.Must(template.ParseFiles("H:\\go\\main\\forms.html"))
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
if r.Method != http.MethodPost {
tmpl.Execute(w, nil)
return
}
details := ContactDetails{
Email: r.FormValue("email"),
Subject: r.FormValue("subject"),
Message: r.FormValue("message"),
}
// do something with details
_ = details
tmpl.Execute(w, struct {
Success bool}{
true})
})
http.ListenAndServe(":8080", nil)
}
HTML template file content:
<!DOCTYPE html>
{
{if .Success}}
<h1>Thanks for your message!</h1>
{
{else}}
<h1>Contact</h1>
<form method="POST">
<label>Email:</label><br />
<input type="text" name="email"><br />
<label>Subject:</label><br />
<input type="text" name="subject"><br />
<label>Message:</label><br />
<textarea name="message"></textarea><br />
<input type="submit">
</form>
{
{end}}
