In my MVC application, i have information upload form. Here user can upload videos and images. To do this i have created to file controls, one for videos and one for images. Here user should be only able to upload at max 2 videos and at max 5 images for single form. Can any one suggest me how can i limit the user to upload number of files. ie if only 2 videos and 5 images also where should i implement this for best use? in controller
or using javascript
?
The MVC file upload approach:
<input type="file" name="file" id="file" />
This passes a HttpPostedFileBase
to the controller or if you have multiple IEnumerable<HttpPostedFileBase>
. You can then evaluate the number of files and file types and return any functionality/messages back to the user.
[HttpPost]
public ActionResult Index(HttpPostedFileBase file) {...
Or
<input type="file" name="files" id="file" />
<input type="file" name="files" id="file" />
[HttpPost]
public ActionResult Index(IEnumerable<HttpPostedFileBase> files) {...
I tried using javascript
File upload control :
<input type="file" id="t" name="t" onchange="checkFilesCount(this)" multiple>
javascript code :
function checkFilesCount(id) {
if(id.files.length > 5)
{
alert('you cant upload files more than 5');
document.getElementById("t").value = "";
}
}
