How to make sure your input field can only upload images
I had the need to have a file upload for images, so I added my little input type="file" field:
<input type="file">I only wanted images to be allowed to be uploaded by the browser.
It’s a common thing, but I always forget how to do it.
Use the accept attribute and pass image/* to allow all images:
<input type="file" accept="image/*">Or image/png to only accept PNG images:
<input type="file" accept="image/png">The same syntax can be done to only accept videos:
<input type="file" accept="video/*">or audio:
<input type="file" accept="audio/*">Or a combination of them:
<input type="file" accept="image/*,audio/*,video/*">Oh common thing - add multiple to allow uploading more than one:
<input type="file" multiple accept="image/*">Of course this is only client-side validation, and you should also validate the mime type on the server when you receive the files.
