Google reCAPTCHA CodeIgniter 4 Library

Installation

## Configuration

In the .env file you need to add your personal ReCaptcha keys.

recaptcha2.key = 'XXXXXXXX-XXXXXXXX' recaptcha2.secret = 'XXXXXXXX-XXXXXXXX'

recaptcha3.key = 'XXXXXXXX-XXXXXXXX' recaptcha3.secret = 'XXXXXXXX-XXXXXXXX' recaptcha3.scoreThreshold = 0.5

In the /app/Config/Validation.php file you need to add settings for validator:

public $ruleSets = [ ... \Denis303\ReCaptcha\Validation\ReCaptchaRules::class ];

### Rendering ReCaptcha v2

helper(['form', 'reCaptcha']);

echo form_open();

echo reCaptcha2('reCaptcha2', ['id' => 'recaptcha_1'], ['theme' => 'dark']);

echo form_submit('submit', 'Submit');

echo form_close();

### Rendering ReCaptcha v3

helper(['form', 'reCaptcha']);

echo form_open();

echo reCaptcha3('reCaptcha3', ['id' => 'recaptcha_1'], ['action' => 'contactForm']);

echo form_submit('submit', 'Submit');

echo form_close();

### Checking ReCaptcha in a model:

public $validationRules = [ 'reCaptcha2' => 'required|reCaptcha2[]' 'reCaptcha3' => 'required|reCaptcha3[contactForm,0.9]' .... ]; ```

In the settings of the reCaptcha3 validator, the first parameter you specify is expectedAction, this parameter is not required.

You can override global scoreThreshold parameter in the second rule parameter.

protected $validationMessages = [ 'reCaptcha' => [ 'reCaptcha3' => 'Captcha is not valid.' ] ];
