Usage

Using the Facade

You can also use the Recaptcha facade directly in your controllers or other classes:

use NguyenHuy\Recaptcha\Facades\Recaptcha;

class ContactController extends Controller
{
    public function store(Request $request)
    {
        // Verify the token
        $token = $request->input('g-recaptcha-response');
        $ip = $request->ip();
        $action = 'contact_form';
        $minScore = 0.5;
        
        $result = Recaptcha::verify($token, $ip, [$action, $minScore]);
        
        if (!$result) {
            return back()->withErrors(['captcha' => 'reCAPTCHA verification failed']);
        }
        
        // Process form submission
        // ...
    }
}

Blade directive

This directive imports the recaptcha JavaScript library and configures it with your site key.

<body>
    {{-- your app --}}

    {{-- Default action is "form" --}}
    @recaptchaJs

    {{-- or custom action --}}
    @recaptchaJs('form')
</body>

Use on the form

<form>
    {{-- your input --}}

    {{-- Default name is "g-recaptcha-response" --}}
    @recaptchaInput

    {{-- or custom name --}}
    @recaptchaInput('custom-name')
    
    {{-- with custom attributes and action --}}
    @php
        $attributes = ['data-form' => 'contact'];
        $action = 'contact_form';
        $name = 'g-recaptcha-response';
    @endphp
    @recaptchaInput($name)
</form>

Use on the validator

$request->validate([
    'g-recaptcha-response' => 'captcha'
]);

Optimizing Views

php artisan view:clear

Advanced Features

Auto Token Refresh

reCAPTCHA tokens expire after 2 minutes. This library now automatically refreshes tokens every 90 seconds to ensure your forms always have valid tokens.

Error Handling

Improved error handling with detailed logging when verification fails, making it easier to debug issues.

Custom Attributes

You can now add custom HTML attributes to the reCAPTCHA input field:

$attributes = ['data-form' => 'contact', 'class' => 'recaptcha-input'];
$captcha = new \NguyenHuy\Recaptcha\CaptchaV3();
$display = $captcha->display('g-recaptcha-response', $attributes);

Action-specific Validation

You can specify different actions for different forms and validate them accordingly:

// In your form
@php
    $action = 'contact_form';
@endphp
@recaptchaInput('g-recaptcha-response')

// In your controller
$request->validate([
    'g-recaptcha-response' => 'captcha:contact_form,0.7'
]);
