Basic Usage

Livewire Component

<?php

namespace App\Livewire;

use Livewire\Component;
use SnipifyDev\LaravelCaptcha\Rules\RecaptchaValidationRule;

class ContactForm extends Component
{
    public $name = '';
    public $email = '';
    public $message = '';
    public $captchaToken = '';
    
    public function submit()
    {
        $this->validate([
            'name' => 'required|min:3',
            'email' => 'required|email',
            'message' => 'required|min:10',
            'captchaToken' => ['required', new RecaptchaValidationRule('contact')],
        ]);
        
        // Process your form here...
        $this->reset();
        session()->flash('success', 'Message sent successfully!');
    }
    
    public function render()
    {
        return view('livewire.contact-form');
    }
}

Livewire View

<div>
    <form wire:submit.prevent="submit" class="space-y-4">
        <div>
            <label>Name</label>
            <input type="text" wire:model="name">
            @error('name') <span class="text-red-500">{{ $message }}</span> @enderror
        </div>
        
        <div>
            <label>Email</label>
            <input type="email" wire:model="email">
            @error('email') <span class="text-red-500">{{ $message }}</span> @enderror
        </div>
        
        <div>
            <label>Message</label>
            <textarea wire:model="message"></textarea>
            @error('message') <span class="text-red-500">{{ $message }}</span> @enderror
        </div>
        
        {{-- Captcha field --}}
        <x-captcha-livewire-field wire-model="captchaToken" action="contact" />
        @error('captchaToken') <span class="text-red-500">{{ $message }}</span> @enderror
        
        <button type="submit">Submit Form</button>
    </form>
</div>

Traditional Controller

<?php

use Illuminate\Http\Request;
use SnipifyDev\LaravelCaptcha\Rules\RecaptchaValidationRule;

class ContactController extends Controller
{
    public function store(Request $request)
    {
        $validated = $request->validate([
            'name' => 'required|string|max:255',
            'email' => 'required|email',
            'message' => 'required|string|min:10',
            'g-recaptcha-response' => ['required', new RecaptchaValidationRule('contact')],
        ]);
        
        // Process form...
        return back()->with('success', 'Message sent!');
    }
}

Components

Livewire Field Component

<x-captcha-livewire-field 
    wire-model="captchaToken"     {{-- Required: Livewire property --}}
    action="contact"              {{-- Optional: Action for v3 scoring --}}
    version="v3"                  {{-- Optional: Force version (v2/v3) --}}
/>

Include Scripts

Add this to your layout before closing </body> tag:

<x-captcha-script />

Validation Rules

// Basic usage with any action name
new RecaptchaValidationRule('login')
new RecaptchaValidationRule('contact') 
new RecaptchaValidationRule('signup')
new RecaptchaValidationRule('any_action_name')

// Force specific version if needed
new RecaptchaValidationRule('login', null, 'v2')  // Force v2
new RecaptchaValidationRule('login', null, 'v3')  // Force v3

Testing

The package automatically disables validation in testing environments:

public function test_contact_form_submission()
{
    $response = $this->post('/contact', [
        'name' => 'John Doe',
        'email' => 'john@example.com',
        'message' => 'Test message',
        'captchaToken' => 'fake-token', // Ignored in testing
    ]);
    
    $response->assertRedirect()->assertSessionHas('success');
}

Troubleshooting

Common Issues

"Site key not found" Error

php artisan config:clear
# Verify your .env keys are correct

Validation Always Fails

• Check your secret key is correct in .env
• Verify the site key matches your domain
• Enable fake mode for development: RECAPTCHA_FAKE_DEVELOPMENT=true

JavaScript Errors

• Include <x-captcha-script /> before </body>
• Check browser console for errors

Livewire Integration

• Ensure your component has public $captchaToken = '';
• Use wire-model="captchaToken" in the component

Configuration

Optionally publish the config file for advanced customization:

php artisan vendor:publish --tag=recaptcha-config
