CaptchaBundle

Provides captcha to your controllers and views This is a port of Zend_Captcha_Image to use native symfony session

Default images folder is /img/captcha so create it first. you also need to enable session in your app.config

How to install:

git submodule add git://github.com/biGGer/CaptchaBundle.git src/Bundle/CaptchaBundle

Add CaptchaBundle to your application kernel

// app/AppKernel.php
public function registerBundles()
{
    return array(
        // ...
        new BundleCaptchaBundleCaptchaBundle(),
        // ...
    );
}

Example initialization:

use BundleCaptchaBundleImage as Captcha;
// ...
$captcha = new Captcha();
$captcha->setSession($this['session']);
return $this->render('MyBundle:MyController:index.twig', array('captcha' => $captcha));

And inside template:

<?php $captcha->render() ?>
or in twig:
{{ captcha.render }}

Check if valid:

if ($this['session']->get['word'] === $this['request']->request->get('riddle')) {
echo 'pass!';
}
