I’m trying to build a very basic page that takes user input from a form and displays it within an html template
Here’s the code that should take the input data from a form and make it available as a variable in the template. The input is printed to console for sanity check, it does show correctly in there.
func processor(w http.ResponseWriter, r *http.Request) {
if r.Method != "POST" {
http.Redirect(w, r, "/", http.StatusSeeOther)
return
}
userName := r.FormValue("user")
userPronouns := r.FormValue("pronouns")
d := struct {
hostName string
hostPronouns string
}{
hostName: userName,
hostPronouns: userPronouns,
}
tpl.ExecuteTemplate(w, "processor.gohtml", d)
fmt.Println(d.hostName)
fmt.Println(d.hostPronouns)
}
Here is the html code that should display part of the information from the form. Eventually it’s going to be more complicated but for now I just need it to work.
<body>
<h1>BALLS</h1>
<h2> {{.hostName}} </h2>
</body>
I can’t figure out why the data doesn’t show up. If I change the {{.hostName}} for {{.}} all the data from the form is there, so it is going through.
>Solution :
struct fields have to be exported to be available in templates.
Change your struct to
d := struct {
HostName string
HostPronouns string
}
