I parsed my template files to make it easier for me to work.
I named them {{define "pagearea"}}.
For example {{define "footer"}}.
Folder layout
- footer.tmpl - footer area
- index.tmpl - my home page
- main.go - go code :)
- topheader.tmpl - part of top html
main.go
package main
import (
"log"
"os"
"html/template"
)
type Home struct {
Sitelang string
Sitetitle string
Sitename string
Siteslogan string
}
func main() {
homeTmpl, err := template.ParseFiles("./topheader.tmpl", "./footer.tmpl", "./index.tmpl")
if err != nil {
log.Fatal("Home page parsing error:", err)
}
data := Home{Sitelang: "en",
Sitetitle: "Home - Render Test",
Sitename : "test 1",
Siteslogan: "mmmmeeeeeuaawww!"}
homeTmpl.Execute(os.Stdout, data)
}
footer.tmpl:
{{define "footer"}}
<footer>
<small>
This is footer area. Test.</small>
</footer>
</body>
</html>
{{end}}
index.tmpl:
{{template "topheader"}}
<h1>
Main area</h1>
{{template "footer"}}
topheader.tmpl:
{{define "topheader"}}
<!DOCTYPE html>
<html lang="
{{.Sitelang}}">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>
{{.Sitetitle}}</title>
</head>
<body>
<header>
<h1>
{{.Sitename}}
</h1>
<p>
{{.Siteslogan}}
</p>
</header>
{{end}}
Build command: go build .
I really don't know what I'm missing. What's wrong here?
You used
template.ParseFiles()to parse the template files. This will parse all files, and return a template that will "contain" all parsed templates as associated templates. The returnedtemplate.Templatewill represent the first template. Quoting fromtemplate.ParseFiles():Then you use
Template.Execute()which executes the template whose method you're calling. So in your case that will betopheader.tmpl, but that template does not generate any output, that template just defines a template:{{define "topheader"}}.Most likely you want to execute the
index.tmpl, so useTemplate.ExecuteTemplate()where you can identify the executable template by its name (and don't forget to check the returned error):Another mistake is that when your
index.htmltemplate includes (executes) other templates using the{{template}}action, you don't pass any parameter to them, yet you want to use the initial parameters.So pass the current params when invoking other templates. Your
index.htmlshould be:See related questions:
