HttpPostedFileBase.SaveAs working but no file uploaded and no exceptions

Question

First, here is my code:

private Shoe ProcessForm(Shoe shoe, HttpPostedFileBase image)
{
    try
    {
        shoe.Slug = CMSHelper.SanitizeTitle(shoe.Name);
        shoe.LastModification = DateTime.Now;

        if ((image != null) && (image.ContentLength > 0))
        {
            string fileName = String.Concat(shoe.ShoeId, Path.GetExtension(image.FileName));
            shoe.Image = fileName;

            string filePath = Path.Combine(Server.MapPath(shoe.ImagePath), fileName);
            image.SaveAs(filePath);
        }
    }
    catch (Exception e)
    {
        throw e;
    }

    return shoe;
}

Locally, this code works fine. Directories' permissions are fine. And it has worked before randomly on other servers (I tested this code on 4 or 5 different servers while I was testing VPS providers).

But if I try to run it from my home computer, everything passes alright, there's a file name saved in the database but no file is uploaded. And no exceptions are given!!!

I've been trying to fix this for almost three days and so much useless hours, please help me... I just don't see what's wrong with this...

Answer 1

What is your view model? First of all replace (Shoe shoe, HttpPostedFileBase image) with (FormCollection formCollection). Put a breakpoint on that to see that you are getting all the submitted values. If you do then there is a problem with model binding and we'll need to address that.

Edit

Can you please put a breakpoint on

image.SaveAs(filePath); 

Add a watch for fileName and filePath variables. I think that server path is not what you expect it to be, or maybe you are looking in the wrong folder all together. Tell us what are the values of those variables. Also make sure that no exception is thrown when you go past image.SaveAs(filePath);
