Easy integration with [mewebstudio/captcha](https://github.com/mewebstudio/captcha) for the Filament forms.

## Requirements:

- PHP extension: ext-gd

## Installation

Install the package via composer:

```bash
composer require yepsua/filament-captcha-field
```

Publish the package mewebstudio/captcha config file:

```bash
php artisan vendor:publish --provider="Mews\Captcha\CaptchaServiceProvider" --tag="config"
```

## Usage

You can include the captcha field like any other filament field.

```php
use Yepsua\Filament\Forms\Components\Captcha;
...
protected function getFormSchema(): array
{
return [
Forms\Components\TextInput::make('username'),
Forms\Components\TextInput::make('password')->type('password'),
Captcha::make('captcha')
];
}

```

You can also just display the image and validate the captcha using any other TextInput field:

```php
use Yepsua\Filament\Forms\Components\CaptchaImage;
...
protected function getFormSchema(): array
{
return [
Forms\Components\TextInput::make('username'),
Forms\Components\TextInput::make('password')->type('password'),
Forms\Components\TextInput::make('captcha')->required()->rules('required|captcha'),
CaptchaImage::make('captchaImg')
];
}

```

The captcha uses by default the `flat` config. You can create/update the captcha configs in the file: `config/captcha.php`.

You can switch to any other available captcha config, like the `math` config:

```php
use Yepsua\Filament\Forms\Components\Captcha;
...
protected function getFormSchema(): array
{
return [
Captcha::make('captcha')->config('math')
];
}
```

For more info about the captcha configuration, please read the [mewebstudio/captcha](https://github.com/mewebstudio/captcha) documentation.

## Translations

This package and mewebstudio/captcha don't provide any translation for the captcha validation message, but you can translate the message by yourself, just add the item in the file `resources/lang/{lang}/validation.php`

```php
return [
...
'captcha' => 'Invalid captcha.',
...
]
```

## Case of use: Add a captcha in the filament login form:

1. Extend the Login page class to add the new field into the form:

```php

[
'guard' => env('FILAMENT_AUTH_GUARD', 'web'),
'pages' => [
// 'login' => \Filament\Http\Livewire\Auth\Login::class, // <- Original form
'login' => \App\Filament\Pages\Auth\Login::class, // <- Form with captcha
],
],
...
]
```

3. Done. Finally you can test the captcha in the login form.



## Testing

```bash
composer test
```
