IP Address Validation in Controller in Laravel 5

Question

I am trying to find a method to validate IP Address before submitting this to my database, I have tried a lot of Google Search but unable to do this in my Laravel Controller. Can you please help? Appreciated

Answer 1

Use inside your controller. Import validator class's namespace and try it for validating IP (IP4/ IP6) address. Laravel 5 and Laravel 5.X

public function update(Request $request) 
{
   $validator = Validator::make($request->all(), [
        'ip_address' => 'required|ip'
    ]);
}

if ($validator->fails()) {
    return "Invalid IP address!"
}

If you want to validate IP4 and IP6 respectively, then use following code.

'ip_address' => 'required|ipv4'

'ip_address' => 'required|ipv6'

Happy Coding !!!

You could do it either inside the controller itself:

public function update(Request $request)
{
    // Get the current users IP address and add it to the request
    $request->merge(['ip_address' => $_SERVER['REMOTE_ADDR']]);

    // Validate the IP address contained inside the request
    $this->validate($request, [
        'ip_address' => 'required|ip'
    ]);
}

The $request->merge() method will allow you to add items to the form request, and then you can just make a simple validate request on the IP only.

Alternatively, you could move all this to it's own Request class and inject that into the method.
