Laravel validation no space allowed for username

Question

I have a little problem in laravel validation request. I want to reject username with space like foo bar. I just want to allow foobar without space. Right now my rule is required|unique:user_detail,username. What rule should i use? thanks

You can extend the validator with your own custom rules:

Validator::extend('without_spaces', function($attr, $value){
    return preg_match('/^\S*$/u', $value);
});

Then just use as any other rule:

required|without_spaces|unique:user_detail,username

Checkout the docs on custom validation rules:
