README

Be careful version 1.0 is for CakePHP 3.6 minimum. For a previous CakePHP version please use the 0.4.2 version.

Plugin's Objective

This plugin adds functionalities to use the new reCAPTCHA API version 2.0 in CakePHP projects.

This plugin is still under development... For now, multiple widgets on a single page is not available.

Requirements

• PHP >= 5.4.16
• CakePHP 3.x
• Server under localhost name. Be aware that the widgets will not be displayed if you have a vhost named local.dev/dev/ for instance.

Installation

[Using Composer]

Add the plugin to your project's composer.json - something like this:

composer require cakephp-fr/recaptcha:~1.0

You then need to load the plugin, by running:

bin/cake plugin load -rb Recaptcha

You can check that this command has created the line Plugin::load('Recaptcha', ['routes' => true, 'bootstrap' => true]); at the bottom of your config/boostrap.php file.

The 'routes' => true should be deleted in production. It's only useful if you want to see the demo.

Usage of plugin

1. Go to Google reCAPTCHA site

Go here to create a pair of keys for your website.

2. Configure the plugin

The Easiest way is to add the recaptcha config to the config/app.php, something like:

return [

    .... (other configs before)

    'Recaptcha' => [
        // Register API keys at https://www.google.com/recaptcha/admin
        'sitekey' => 'your-sitekey',
        'secret' => 'your-secret',
        // reCAPTCHA supported 40+ languages listed
        // here: https://developers.google.com/recaptcha/docs/language
        'lang' => 'en',
        // either light or dark
        'theme' => 'light',
        // either image or audio
        'type' => 'image',
        // either normal or compact
        'size' => 'normal'
    ]
]

Make sure that /config/app.php file is in .gitignore. The secret key must stay secret.

If you don't have a key and a secret, an exception will be raised.

3. Then add the component in your controller where you need the reCAPTCHA.

For example:

public function initialize() {
    parent::initialize();
    if ($this->request->getParam('action') === 'contact') {
        $this->loadComponent('Recaptcha.Recaptcha');
    }
}

public function contact() {
    if ($this->request->is('post')) {
        if ($this->Recaptcha->verify()) {
            // Here you can validate your data
            if (!empty($this->request->getData())) {
                $this->Flash->success(__('We will get back to you soon.'));
                return $this->redirect($this->referer());
            } else {
                $this->Flash->error(__('There was a problem submitting your form.'));
            }
        } else {
            // You can debug developers errors with
            // debug($this->Recaptcha->errors());
            $this->Flash->error(__('Please check your Recaptcha Box.'));
        }
    }
}

4. Finally add <?= $this->Recaptcha->display() ?> in your view template inside the form.

No need to add the helper: it will be added with the component.

For example:

<?= $this->Form->create() ?>

<?= $this->Form->control('name', [
  'label' => __('Your Name'),
  // 'default' => $this->request->query('name'); // in case you add the Prg Component
]) ?>
<?= $this->Form->control('message', [
  'type' => 'textarea',
  // 'default' => $this->request->query('message'); // in case you add the Prg Component
  'label' => __('Your Message')
]) ?>

<?= $this->Recaptcha->display() ?>

<?= $this->Form->button(__('OK')) ?>
<?= $this->Form->end() ?>

See another example of contact with no form in src/Controller/ContactController.php, src/Template/Contact/index.ctp and src/Form/ContactForm.php. You can test it by going to http://localhost/recaptcha/contact.
