uploaded file-size validation

[sumittyagi]

If we want to upload file, we you the tag:
<input type="file" name="fileName"/>

Now is it possible to get the size of the uploaded file before submitting it.(at onsubmit)

or we would have to do that at server side only.

One thing is you should not double post. Actually, starting a new thread as you have done is here was the correct way to go.

The answer to your query which I answered in the other thread too is that only IE supports the fileSize property.

In any case, you will need server side code for file size checking in case someone disables javascript or uses some other method to bypass your security checks on the client-side.

Thanks for your reply acoder. And I am sorry for double posting! I will remember this in my future posts.

No problem.

Sorry to throw a spanner in the works...

As far as I am aware, once the file has been selected you can do an onchange event on the file field, create a image object in js, give the image object the source (in the file field) .src, and then do some tests using javascript. You should be able to attach an onload event to the image to check it's loaded before getting the heights and widths, although I'm not sure if that is frowned upon these days.

Hope that helps.
