How to transfer data of another form along with downloading MVC files?

Question

I am trying to implement file upload in MVC. I have the following code that works.

@using (Html.BeginForm("ActioName", "ControllerName", FormMethod.Post, new { enctype = "multipart/form-data" }))
{         
       <div>
            <input type="file" name="file" />
            <input type="submit" value="OK" class="button" />
        </div>       
}

      [HttpPost]
      public ActionResult UploadFile(HttpPostedFileBase file)
       {
        // Verify that the user selected a file
        if (file != null && file.ContentLength > 0)
        {
        //do something here...
        }
      }

Now I want to add a drop-down list (to select the file type) and send this value along with the file to my controller. How can I do this (send other form data along with the file)?

You should be able to add them to the view, include them in POST and MVC to take care of model binding:

@using (Html.BeginForm("ActioName", "ControllerName", FormMethod.Post, new { enctype = "multipart/form-data" }))
{         
       <div>
            <input type="file" name="file" />
            <select name="fileType">
               <option value="JPG">Photo</option>
               <option value="DOC">Word</option>
            </select>
            <input type="submit" value="OK" class="button" />
        </div>       
}

      [HttpPost]
      public ActionResult UploadFile(HttpPostedFileBase file, string fileType)
      {
        //Validate the fileType

        // Verify that the user selected a file
        if (file != null && file.ContentLength > 0)
        {
        //do something here...
        }
      }

I ended up doing it as follows. works well for me:

Created a model:

public class FeeUpload
{
    [Required (ErrorMessage="File Type required")]       
    public string fileType { get; set; }

    [Required (ErrorMessage="file required")]
    public HttpPostedFileBase File { get; set; }

}

:

@using (Html.BeginForm("ActionName", "ControllerName", FormMethod.Post, new { enctype = "multipart/form-data" }))
{ 
    @Html.ValidationSummary(false, "Please fix the following:")
    <div>
       <div>
            @Html.DropDownListFor(model => model.fileType,
                                   new List<SelectListItem>
                                         {
                                            new SelectListItem{ Text="xxx", Value = "yyy" }, 
                                            new SelectListItem{ Text="xxx", Value = "yyy" },
                                            new SelectListItem{ Text="xxx", Value = "yyy" }
                                         }, "Select")
            @*@Html.ValidationMessageFor(model => model.fileType)*@
        </div>

        <div>
            @Html.TextBoxFor(model => model.File, new { type = "file" })
            @*@Html.ValidationMessageFor(model => model.File)*@  
            <input type="submit" value="OK" class="button" id="btnsubmit" />
        </div>
    </div>
}

:

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult FeesAndCostsUpload(FeeUpload feeUploadFile)          
    {
        if (ModelState.IsValid)
        {
           //do something with feeUploadFile.File and feeUploadFile.fileType          
        }
        return View();
    }

Razor

<form method="POST" data-url="@Url.Action("Action", "Controller")" enctype="multipart/form-data">
        @Html.ValidationSummary(true)

        <span class="btn btn-success fileinput-button">
            <i class="fa fa-plus"></i>
            <span>Add a file...</span>
            @Html.TextBoxFor(model => model.Fichier, new { type = "file" })
        </span>

        <div class="form-group form-actions">
            <div class="col-sm-offset-3 col-sm-9">
                <input id="submit" type="submit" class="btn btn-primary" value='Value' />
            </div>
        </div>
    </form>
