golang post data using content-type multipart/form-data

http-post file multipart programming in go language

and answers not helpful, because i'm error multipart.newwriter. version of go lang 1.3.3

i'm trying send text data , image form(templates/form.html)

    <form enctype="multipart/form-data" method="post">       <div class="row">         <div class="large-6 columns">           <label>image             <input type="file" name="image" class="button"/>           </label>         </div>       </div>     <div class="row">         <div class="large-12 columns">           <label>about me             <textarea type="text" name="aboutmyself" class="aboutmyself"></textarea>           </label>         </div>     </div> </form> 

and go approach this:

package main  import (      "fmt"     "html/template"     "io"     "log"     "net/http"     "net/textproto"     "os"     "reflect"     "time"      "github.com/gorilla/mux"     "github.com/gorilla/schema"  )    func render(w http.responsewriter, tmpl string, context map[string]interface{}) {     tmpl_list := []string{fmt.sprintf("templates/%s.html", tmpl)}     t, err := template.parsefiles(tmpl_list...)     if err != nil {         log.print("template parsing error: ", err)     }     err = t.execute(w, context)     if err != nil {         log.print("template executing error: ", err)     } }     type fileheader struct {         filename string         header   textproto.mimeheader         // contains filtered or unexported fields     }      func uploadimage(q *http.request, nameinform string) {         q.parsemultipartform(32 << 20)          file, _, err := q.formfile(nameinform)          if err != nil {             fmt.println(err)          }         defer file.close()          f, err := os.openfile("./static/uploadimages/"+handler.filename+".jpg", os.o_wronly|os.o_create, 0666)         if err != nil {             fmt.println(err)          }         defer f.close()         io.copy(f, file)     } func main() {      rtr := mux.newrouter()        //admin section     rtr.handlefunc("/myself", myself).methods("get")     rtr.handlefunc("/myself", myselfp).methods("post")       rtr.pathprefix("/").handler(http.fileserver(http.dir("./static/")))      http.handle("/", rtr)      log.println("listening...")     http.listenandserve(":3000", nil) } func myself(w http.responsewriter, q *http.request) {      render(w,"form",nil)  } func myselfp(w http.responsewriter, q *http.request) {     err := q.parseform()      if err != nil {         // handle error         fmt.println(err)     }      uploadimage(q, "image")       http.redirect(w, q, "/myself", http.statusfound)  } 

file uploads perfectly, cann't data textarea. i'm trying understand different between simple form fields , multipart form, , how can data fields

thanks , regards
