http://www.google
unfortunately laravel validation code as
['redirect_url' => 'required|url']
return false for this urls:
www.google.com
and return true for http://www.google address, how to check correctly urls in laravel, this validation is not best validation for urls

Answer 1

You can use regex validation rule for URL validation
['redirect_url' => ['required','regex:/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&##\/%?=~_|!:,.;]*[-a-z0-9+&##\/%=~_|]/i']]

Answer 2

Before validation check if string contains http:// or https:// with this code:
if(!(starts_with($url, "http://") || starts_with($url, "https://")) {
$url = "http://".$url;
}
Function starts_with() is helper function from Laravel. docs

Answer 3

The regex solution that Jay Dhameliya provided is probably the best one for your scenario but I just thought I would explain why the url validator doesn't work as you expected.
If you look at the illuminate/validation/Validator validateURL function it is expecting a the following to be specified as part of the URL.
protocol ( http/https/etc )
optional basic auth
a domain or ip address
optional port
a trailing / or nothing or / followed by something else
There doesn't seem to be any alternatives provided for this validator method or ways to say don't require the protocol. So once again a custom regex seems the best option. If you are planning on using it in more than one place you might want to consider creating your own Custom Validation Rule see the docs for details.
