form with multiple upload but allow no upload on edit problems
- by minus4
hiya
i have a section that when created takes in images, however when you edit this item
i dont want them to re-upload none changes images just to change a description or name.
i have created this that deals with uploading files:
public void UploadFiles(string currentFileName, FormCollection form)
{ // loop through all files in form post
foreach (string file in Request.Files)
{
HttpPostedFileBase hpf = Request.Files[file];
// if no file is uploaded, we could be editing so set to current value
if (hpf.ContentLength == 0)
{
form[file] = currentFileName;
}
else
{ //rename the file unique so we dont clash with names
var filename = hpf.FileName.Replace(" ", "_").Replace(".", DateTime.Now.Date.Ticks + ".");
UploadFileName = filename;
hpf.SaveAs(Server.MapPath("~/Content/custom/" + filename));
// set the name of the file in our post to the new name
form[file] = UploadFileName;
}
}
// ensure value is still sent when no files are uploaded on edit
if(Request.Files.Count <= 0)
{
UploadFileName = currentFileName;
}
}
all works fine when only one image is required (CurrentFileName), however there is now a new image available taking it to a total of 2 images in the database therefor currentFileName is obsolete. has anyone tackled this and how as i have hit a wall with this one. thought of string[] currentFiles but cant see how to match this into string file in Request.Files.
if it helps i am also working with models for the form so i could pass over the model but i dont think your able to do model.file without some kind of reflection.
help much appreciated.
thanks
