Honeypot for Symfony2 forms.

What is Honey pot?

A honey pot trap involves creating a form with an extra field that is hidden to human visitors but readable by robots. The robot fills out the invisible field and submits the form, leaving you to simply ignore their spammy submission or blacklist their IP. It’s a very simple concept that can be implemented in a few minutes and it just works – add them to your contact and submission forms to help reduce spam.

Prerequisites

This version of the bundle requires Symfony 2.1+

Installation

Step 1: Download EoHoneypotBundle using Composer

Add EoHoneypotBundle to your project by running the command:

$ composer require eo/honeypot-bundle

Composer will install the bundle to your project's vendor/eo directory.

Step 2: Enable the bundle

If you use Symfony Flex - skip this step. Otherwise, enable the bundle in bundles.php:

<?php
// config/bundles.php

<?php
return [
    // ...
    Eo\HoneypotBundle\EoHoneypotBundle::class => ['all' => true],
];

Step 3 (optional): Configure bundle to use database

To save honeypot catched requests into database you have to enable it in your configuration file: All parameters are optional

# config/packages/eo_honeypot.yaml
eo_honeypot:
    storage:
        database:
            enabled: false
            driver: mongodb # orm and mongodb are supported
            class: ApplicationEoHoneypotBundle:HoneypotPrey
        # You can also use file format to store honeypot preys.
        # This may come handy if you need to parse logs with fail2ban
        # file:
            # enabled: false
            # output: /var/log/honeypot.log
    redirect:
        enabled: true
        url: "/"
        # route: homepage
        # route_parameters: ~

If you enable the database storage, you must create a class which extends the Eo\HoneypotBundle\<Entity|Document>\HoneypotPrey base class :

<?php
namespace Application\Eo\HoneypotBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Eo\HoneypotBundle\Entity\HoneypotPrey as BaseHoneypotPrey;

/**
 * @ORM\Entity
 */
class HoneypotPrey extends BaseHoneypotPrey
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    public function getId()
    {
        return $this->id;
    }
}

or

<?php
namespace Application\Eo\HoneypotBundle\Document;

use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;
use Eo\HoneypotBundle\Document\HoneypotPrey as BaseHoneypotPrey;

/**
 * @MongoDB\Document
 */
class HoneypotPrey extends BaseHoneypotPrey
{
    /**
     * @MongoDB\Id
     */
    protected $id;

    public function getId()
    {
        return $this->id;
    }
}

Usage

Once installed and configured you can start using Eo\HoneypotBundle\Form\Type\HoneypotType form type in your forms.

Basic usage example:

<?php

namespace Acme\DemoBundle\Form\Type;

use Eo\HoneypotBundle\Form\Type\HoneypotType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;

class FooType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name', TextType);
        $builder->add('email', EmailType);

        // Honeypot field
        $builder->add('SOME-FAKE-NAME', HoneypotType::class);
    }
}

Events

If the hidden honeypot field has some data bundle will dispatch a bird.in.cage event. You can create an event listener to execute custom actions. See Eo\HoneypotBundle\Event\BirdInCage and How to Register Event Listeners and Subscribers for more information.
