Can't get data from field in gohtml file-CodePudding

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.

CodePudding user response：

struct fields have to be exported to be available in templates.
Change your struct to

d := struct {
  HostName     string
  HostPronouns string
}
