In the user profile page of my website, there is a field in url field type, which allows user to enter their website url. But I found that it only works when user entering the url with prefix http:// or https://. However, most users only enter their websites as www.mywebsite.com, without the prefix.
Is their any way to enforce users to enter the http://, or automatically add the "http://" part if users did not enter it? Thanks.
