Golang中上传文件及其他字段问题如何解决

Golang中上传文件及其他字段问题如何解决 我上传了包含其他字段（如 pname、pdescription 等）的文件，但出现了一个错误。 “http: panic serving 127.0.0.1:52987: Error 1054: Unknown column ‘pname’ in ‘field list’” 这是我的前端代码。

<div class="row">
    <div class="col-sm-3"></div>
    <div class="col-sm-6">
      <div class="form-group row">
        <div class="col-md-3">
          <label> Prodcucto name </label>
        </div>
        <div class="col-md-9">
           <input type="text" name="pname" class="form-control" />
        </div>
      </div>

      <div class="form-group row">
        <div class="col-md-3">
          <label> Prodcucto description</label>
        </div>
        <div class="col-md-9">
           <input type="text" name="pdescription" class="form-control" />
        </div>
      </div>

      <div class="form-group row">
        <div class="col-md-3">
         <label>Valorunidade</label>
        </div>
        
        <div class="col-md-9">
          <input type="text" name="cellnumber" class="form-control" />
        </div>
      </div>

      <div class="form-group row">
        <div class="col-md-3">

          <label> Producto img </label>
        </div>
        <div class="col-md-9">
         <input type="file" name="pimg" class="form-control" />
         </div>
      </div>


      <div class="form-group row">
        <div class="col-md-3">

            <label> status </label>
        </div>
        
        <div class="col-md-9">
        <select name="status" class="form-control">
            <option selected>Selecione um status</option>
            <option value="pago">Pago</option>
            <option value="parcial">Parcial</option>
            <option value="em aberto">Em Aberto</option>
        </select>
        </div>
      </div>
    
      <div class="form-group row">
        <div class="col-md-3">
          <label> Obs </label>
        </div>
        <div class="col-md-9">
          <textarea type="text" name="obs" class="form-control"></textarea><br />
        </div>
      </div>
      <button type="submit" class="btn btn-info" value="Gerar Producto">Gerar Producto</button> 
 
    </div>
  </div>
</form>

以及我的上传函数

func ProductStore(w http.ResponseWriter, r *http.Request) {

 r.ParseMultipartForm(10 << 20)
// FormFile returns the first file for the given key `myFile`
// it also returns the FileHeader so we can get the Filename,
// the Header and the size of the file
file, handler, err := r.FormFile("pimg")
if err != nil {
    fmt.Println("Error Retrieving the File")
    fmt.Println(err)
    return
}
defer file.Close()
fmt.Printf("Uploaded File: %+v\n", handler.Filename)
fmt.Printf("File Size: %+v\n", handler.Size)
fmt.Printf("MIME Header: %+v\n", handler.Header)

// Create a temporary file within our temp-images directory that follows
// a particular naming pattern
tempFile, err := ioutil.TempFile("product", "*.png")
fmt.Println(tempFile)
if err != nil {
    fmt.Println(err)
}
defer tempFile.Close()

// read all of the contents of our uploaded file into a
// byte array
fileBytes, err := ioutil.ReadAll(file)
if err != nil {
    fmt.Println(err)
}
// write this byte array to our temporary file
tempFile.Write(fileBytes)
// return that we have successfully uploaded our file!
fmt.Fprintf(w, "Successfully Uploaded File\n")
//Open database connection
db := dbConn()

// Check the request form METHOD
if r.Method == "POST" {

	// Get the values from Form
	pname := r.FormValue("pname")
	pdescription := r.FormValue("pdescription")
	valorunidade := r.FormValue("valorunidade")
	pdatafabi := r.FormValue("pdatafabi")
	pimg := "product.png"
	status := r.FormValue("status")
	obs := r.FormValue("obs")
	// Prepare a SQL INSERT and check for errors
	insForm, err := db.Prepare("INSERT INTO clientes(pname, pdescription, valorunidade, pdatafabi, pimg, status, obs) VALUES(?,?,?,?,?,?,?)")
	if err != nil {
		panic(err.Error())
	}

	// Execute the prepared SQL, getting the form fields
	insForm.Exec(pname, pdescription, valorunidade, pdatafabi, pimg, status, obs)

	// Show on console the action
	log.Println("INSERT: pname " +pname+ " | pdescription " +pdescription+ " | valorunidade " +valorunidade+ " | pdatafabi " +pdatafabi+ " |pimg " +pimg+ " |status " +status+ " |obs " +obs)
}

// Close database connection
defer db.Close()

// Redirect to HOME
http.Redirect(w, r, "/product", 301)
}

问题是什么？
