in ASP.NET MVC HttpPostedFileBase collection has only null items
Question
This is my code:
@using (Html.BeginForm("UploadImages", "Administration", new { _id = Model.Album.AlbumID, enctype = "multipart/form-data" }, FormMethod.Post))
{
<input type="file" name="fileUpload" id="file1" /><br />
<input type="file" name="fileUpload" id="file2" /><br />
<input type="file" name="fileUpload" id="file3" /><br />
<input name="addPhoto" type="submit" value="Добавить фото" />
}
[Authorize]
[HttpPost]
public ActionResult UploadImages(int _id, IEnumerable<HttpPostedFileBase> fileUpload)
{
gb_albumdbEntities1 entityes = new gb_albumdbEntities1();
foreach (var file in fileUpload)
{
if (file == null) continue; // **<---fileUpload items is always null!**
string path = AppDomain.CurrentDomain.BaseDirectory + "Photos/";
if (Path.GetFileName(file.FileName) != null)
{
string filename = file.GetHashCode().ToString();
string fullpath = Path.Combine(path, filename);
file.SaveAs(fullpath);
entityes.Photos.AddObject(new Photo() { AlbumID = _id, PhotoUrl = @"http://site.ru/Photos/" + filename });
}
}
entityes.SaveChanges();
return RedirectToAction("AlbumEdit", new { id = _id });
}
fileUpload items is always null. Where is the problem?Oo

your list if file inputs need to be numbered for model binding to work. In the simplest form your view should look something like this:
<html>
<head>
<title>Index</title>
</head>
<body>
<div>
@using (Html.BeginForm("Index", "Upload", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
for (int i = 0; i < 3; i++)
{
@Html.TextBox(string.Format("fileUpload[{0}]", i), null, new { type="file" })<br />
}
<input name="submit" type="submit" value="Go" />
}
</div>
</body>
</html>
and your controller:
public class UploadController : Controller
{
//
// GET: /Upload/
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(IEnumerable<HttpPostedFileBase> fileUpload)
{
return View();
}
}

Try the following post which I've used myself before. Worked for me.
