README 文档

README

Adds Captcha verification functionality to Laravel based on services API.

Installation

Require this package with composer.

composer require straylightagency/laravel-captcha

Laravel without auto-discovery:

If you do not use auto-discovery, add the ServiceProvider to the providers array in bootstrap/providers.php :

\Straylightagency\LaravelCaptcha\CaptchaServiceProvider::class,

Use this artisan command to publish the captcha.php file inside your config folder :

php artisan vendor:publish --tag=captcha

You must set the site key and secret key based on the service you want to use inside your .env file :

## select your drive here : fake, recaptcha, recaptcha_enterprise or turnstile
CAPTCHA_DRIVER=recaptcha_enterprise

## if you use Google ReCaptcha or ReCaptcha Enterprise :
GOOGLE_RECAPTCHA_SITE_KEY="FAK3S1T3K3Y21AI3C9S3VJZ-V65M1SMWLGEPX4SB"
GOOGLE_RECAPTCHA_API_KEY="FAK3AP1K3YXEFG7V2EV1HK1-RGGGU817475938X1O0"
GOOGLE_RECAPTCHA_PROJECT_ID="project-123456"
GOOGLE_RECAPTCHA_SECRET_KEY="FAK3S3CR3TK3YBQYVMJQYMLT4W57RTFFO0MF38VB"

## if you use Cloudflare Turnstile :
CLOUDFLARE_TURNSTILE_SITE_KEY="FAK3S1T3K3YNPY1AEHI2O6P-6AYWQVLJ8439LG3N"
CLOUDFLARE_TURNSTILE_SECRET_KEY="FAK3S3CR3TK3Y8X1O0T0Q2KBQWLKEDUQYNP6GHE3"

In your languages directory, add an extra translation in every validation.php language file :

'captcha' => 'The captcha is not valid.',

Validation

You can use the captcha_rule() helper function directly inside the validation array :

$validator = Validator::make( $request->all(), [
    // [...]
    'captcha' => ['required', 'string', captcha_rule()],
] );

You can also use the captcha rule macro :

$validator = Validator::make( $request->all(), [
    // [...]
    'captcha' => ['required|string|captcha'], // works too
] );

Use the ->default() method if you want to use the required and string macro with the captcha rule.

$validator = Validator::make( $request->all(), [
    'name' => ['required', 'string'],
    'email' => ['required', 'string', 'email'],
    'content' => ['required', 'string'],
    ...captcha_rule()->default(), 
    // parameter $key_name of default() method allow you to edit the field name.
] );

Some Verifier needs a script tag inside the <head> tag of your HTML page, you can use an helper function to print the right script based on the selected Verifier :

<head>
    <!-- rest of your head tag -->
    {!! captcha_script() !!}
    <!-- rest of your head tag -->
</head>

For more information about frontend integration, check the documentation bellow from the API service you want to use.

Requirement

PHP 8.3 or above
