File input 'accept' attribute - is it useful?

Question

Implementing a file upload under html is fairly simple, but I just noticed that there is an 'accept' attribute that can be added to the `<input type="file" ...>` tag.Is this attribute useful as a way of limiting file uploads to images, etc? What is the best way to use it?Alternatively, is there a way to limit file types, preferably in the file dialog, for an html file input tag?

Answer 1

Hi there. The "accept" attribute can be used to specify the types of files that can be uploaded as such:

<input type="file" accept=".gif,.jpg,.jpeg,.png>

This should be coupled with server side sanitization as well since there are ways to spoof the file type on the client side.

I hope this helps.
