Laravel URL validation using validator

Question

I'am trying to validate a URL to make sure it doesn't contain localhost. I have done it using if-else and want to do it using custom validator. I am lost how it could be done by validator.

if((strpos($request->input('url'), 'localhost') !== false) || 
    (strpos($request->input('url'), 'http://localhost') !== false) ||  
    (strpos($request->input('url'), 'https://localhost') !== false) ||  
    (strpos($request->input('url'), '127.0.0.1') !== false) ||
    (strpos($request->input('url'), 'http://127.0.0.1') !== false) ||
    (strpos($request->input('url'), 'http://127.0.0.1') !== false))
{
    return response()->json([
        'error_description' => 'Localhost in not allowed in URL'
    ], 403);
}

You can already achieve it with existing validation and a regex:

'url' => 'regex:/^http:\/\/\w+(\.\w+)*(:[0-9]+)?\/?$/',

I did not test this, but it is creative with existing validation rules.

You can use the url validator of laravel

Don't Panic Over a year ago

The field under validation must be a valid URL. - localhost is a valid URL, so I don't think this will work.

You can use

'url'   => ['regex' => '/^((?:https?\:\/\/|www\.)(?:[-a-z0-9]+\.)*[-a-z0-9]+.*)$/'],

I hope this will be useful

$messages = [
  'url.required' => 'Đường dẫn bắt buộc nhập',
  'url.url' => 'Url không hợp lệ'
];
    
$data = request()->validate([
  'url' => 'required|url',
], $messages);

You can make use of active_url rule that checks if a url has existing A or AAAA records and is reachable. localhost won't validate true in this case.
