I'm trying to implement google recaptcha in a Laravel app. I basically followed these instructions

My form is sent through Ajax/vue.js (in a component) so in my blade file, I pass my recaptcha public key to my component, like this: <contact :lang="'{{ app()->getLocale() }}'" :grecaptcha="'{{ env('GOOGLE_RECAPTCHA_KEY') }}'"></contact> and I catch it as a prop in my vue component. Then I have these lines in my component: <div class="g-recaptcha"
which submits to my EmailController@emailAdmin where I have an EmailRequest. In that EmailRequest I have this under rules: 'g-recaptcha-response'=>'required|recaptcha' which call a method I have registered in AppServiceProvider: public function boot()

This is the Recaptcha@validate function:

`public function validate()
$client = new Client();
$gRecaptchaResponse = Input::get('g-recaptcha-response');

    $response = $client->post('',
        ['form_params' =>
                'secret' => env('GOOGLE_RECAPTCHA_SECRET'),
                'response' => $gRecaptchaResponse
    $body = json_decode((string)$response->getBody());
    return $body->success;

Somehow the dd($body) returns me {#232
+"success": false
+"error-codes": array:1 [
0 => "invalid-input-response"

I can't figure out why I have an invalid-input-response.

Let me know if you think you can help. I'm willing to tip extras.

I can see what the problem is now. In my vue component a text area with the name g-recaptcha-response <textarea id="g-recaptcha-response" name="g-recaptcha-response" class="g-recaptcha-response" style="width: 250px; height: 40px; border: 1px solid #c1c1c1; margin: 10px 25px; padding: 0px; resize: none; display: none; "></textarea> is created. I need to find how to console.log the value of the g-recaptcha-response from my vue component and then I'll be able to pass it to my controller.

Exactly, That's what I was telling you, g-recaptcha-response is not being able to pass to the controller and so is the error.I have not posted my code on github, beacuse I realized that I was actually using get method to achieve the result.I am working on it and soon wiil come with a solution.Don't woory.

Have you included this line?

<script src=''>

Also try changing your boot() to this

public function boot()

Kindly take a backup before making changes.

Hope it helps.

Hi there. I do have those in my project already. Thanks for the help anywayz !

Tried changing 'App\Validators\Recaptcha@validate' to 'App\Validators\Recaptcha@validate' in boot() ?
Ps: went through some forms found out if you try validate captcha from same page you may get that error for the second time onwards..

Hi, can you try this:

Create a new config value for recaptcha_secret_key and recaptcha_site_key in config/app.php or another custom config file.

And in the boot() like this:

Validator::extend('recaptcha', function ($attribute, $value, $parameters, $validator) {

$recaptcha = new ReCaptcha(config('app.recaptcha_secret_key'));

$resp = $recaptcha->verify($value, request()->ip());

return $resp->isSuccess();


Try if in that way it works.

100% working tested

Hey, this is a quick fix to your problem. I have tested this code and it worked. you EmailRequest.php and set your rules(uncomment g-recaptcha-response line) to

public function rules()
        return [
            'name' => 'required|max:100',
            'email' => 'required|email|max:100',
            'phone' => 'max:15',
            'message' => 'required|max:1500',

2 open Contact.vue and just above add;

That's it.
Hope it helps and a tip would be appreciated.Thank you.

Hi Codeword. I get Undefined index: g-recaptcha-response. You may have something else in there
