Google reCAPTCHA CodeIgniter 4 Library
======================================

[](#google-recaptcha-codeigniter-4-library)

Installation
------------

[](#installation)

`composer require denis303/codeigniter4-recaptcha:dev-master`

Configuration
-------------

[](#configuration)

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

```
# --------------------------------------------------------------------
# ReCaptcha 2
# --------------------------------------------------------------------
recaptcha2.key = 'XXXXXXXX-XXXXXXXX'
recaptcha2.secret = 'XXXXXXXX-XXXXXXXX'

# --------------------------------------------------------------------
# ReCaptcha 3
# --------------------------------------------------------------------
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

[](#rendering-recaptcha-v2)

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

echo form_open();

echo reCaptcha2('reCaptcha2', ['id' => 'recaptcha_v2'], ['theme' => 'dark']);

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

echo form_close();

```

### Rendering ReCaptcha v3

[](#rendering-recaptcha-v3)

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

echo form_open();

echo reCaptcha3('reCaptcha3', ['id' => 'recaptcha_v3'], ['action' => 'contactForm']);

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

echo form_close();

```

### Checking ReCaptcha in a model:

[](#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 a global scoreThreshold parameter in the second reCaptcha3 rule parameter.
