Installation

You can install this plugin into your CakePHP application using composer.

The recommended way to install composer packages is:

composer require crabstudio/recaptcha

Or add the following lines to your application's composer.json:

"require": {
    "crabstudio/recaptcha": "^2.0"
}

followed by the command:

composer update

Load plugin

From command line:

bin/cake plugin load Recaptcha

Or this line to the end of Your_project\config\bootstrap.php

Plugin::load('Recaptcha');

Load Component and Configure

Override default configure from loadComponent:

$this->loadComponent('Recaptcha.Recaptcha', [
    'enable' => true,     // true/false
    'sitekey' => 'your_site_key', //if you don't have, get one: https://www.google.com/recaptcha/intro/index.html
    'secret' => 'your_secret',
    'type' => 'image',  // image/audio
    'theme' => 'light', // light/dark
    'lang' => 'vi',      // default en
    'size' => 'normal'  // normal/compact
]);

Usage

Display recaptcha in your view:

    <?= $this->Form->create() ?>
    <?= $this->Form->control('email') ?>
    <?= $this->Recaptcha->display() ?>  // Display recaptcha box in your view, if configure enable = false, nothing to display here
    <?= $this->Form->button(__('Submit')) ?>
    <?= $this->Form->end() ?>

Enable button on callback if recaptcha successful:

    <?= $this->Form->button(__('Submit'), ['disabled']) ?>
    
    <script>
        function recaptcha_callback(){
            $('button[type="submit"]').prop("disabled", false);
        }
    </script>

Verify in your controller function

    public function forgotPassword() {
        if ($this->request->is('post')) {
            if ($this->Recaptcha->verify()) { // if configure enable = false, always return true
                //do something here
            }
            $this->Flash->error(__('Please pass Google Recaptcha first'));
        }
    }
