ReCAPTCHA ver.2 for Symfony2 applications

You can find full documentation about Google reCAPTCHA API v2 here., _(*1)

Installation

You can install this package with Composer. Add next lines to your composer.json file:, _(*2)

``` json { "require": { "dario_swain/ds-recaptcha-bundle": "dev-master" } }, _(*3)


Add bundle to your AppKernel.php:

``` php
<?php
...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            ...
            new DS\ReCaptchaBundle\ReCaptchaBundle(),
        );

        ...
    }
}

Usage Example

Add to your config.yml:, _(*4)

``` yaml re_captcha: public_key: #YOUR_PUBLIC_KEY# private_key: #YOUR_PRIVATE_KEY# locale: "%locale%", _(*5)


After this you can add reCAPTCHA type to your custom form:

``` php
<?php

namespace AcmeBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class ContactType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('message', 'textarea')
            /** In type add your form alias **/
            ->add('captcha', 'ds_re_captcha', array('mapped' => false))
            ->add('send', 'submit');
    }
}

Next step, you need to add form_theme to your form view, it seems like that:, _(*6)

{% extends 'AcmeBundle::layout.html.twig' %}
{% form_theme form 'ReCaptchaBundle::form_div_layout.html.twig' %}
{% block content %}
    {{ form_start(form) }}
    {{ form_widget(form) }}
    {{ form_end(form) }}
{% endblock %}
