Unfortunately there's no way to get that info consistently among all browsers., there's multiple posts on here about this topic and the conclusion is browsers don't allow it for security purposes.
I did find that in IE 11 they do include the path within the input dom element .value property, but I don't know if that works in other versions, and it does not work in chrome.
$('input[type=file]').change(function () {
console.dir(this.value);
console.dir(this.files[0])
})
Unfortunately that's about the best you can expect. Here's a post that has a couple things you could do to possibly achieve some very specific scenarios.
How to get full path of selected file on change of <input type=‘file’> using javascript, jquery-ajax?
Original Answer (how to get file path "After" it reaches server)
The null param issue I'm thinking is because MVC binds on element name property.
<input type="file" id="encryptfilefield" name="uploadedfile" enctype='multipart/form-data'/>
and your controller action is marked as type string, which is not what your input type is.
you could either change that to this,
[HttpPost]
public ActionResult EncryptFile(HttpPostedFileBase uploadedfile)
{
or try grabbing the file straight from the Request object like below, you'd have to save it somewhere before you get the full path of it though, i don't believe you'll get the filepath of where it originated from, only after you save it.
[HttpPost]
public ActionResult EncryptFile(string uploadedfile)
{
HttpPostedFileBase myfile = Request.Files[0];
if (file.ContentLength > 0)
{
// extract only the fielname
var fileName = Path.GetFileName(file.FileName);
// store the file inside ~/App_Data/uploads folder
var path = Path.Combine(Server.MapPath("~/App_Data/uploads"),fileName);
file.SaveAs(path);
}
/*process the file without uploading*/
return Json(new { status = "success", message = "Encrypted!" });
}
