Overview

Make your website more secure and keep the robots away!

This bundle allows you to add a simple and privacy-friendly captcha to your Symfony's forms.

Requirements

Support	Version
Symfony	^4.0 / ^5.0
PHP	^7.2 / ^8.0

Installation

composer require ady/captcha-bundle --prefer-dist

Use

Add field

Add a new field to your form with CaptchaType. Some options are recommended:

• mapped should set to false if your form is mapped to an entity
• required should set to true

So, your captcha field looks like:

use Ady\Bundle\CaptchaBundle\Form\CaptchaType;

->add('captcha', CaptchaType::class, [
    'mapped' => false,
    'required' => true,
])

Available challenges

• Consonant

Question: What is the third consonant of the word BARBITURIQUE?

Answer: B

• Letter

Question: What is the fifth letter of the word ESCARPOLETTE?

Answer: R

• Vowel

Question: What is the first vowel of the word JACTANCE?

Mechanism

The question is design like What is the %index% %letter% of the word %word%?. The challenge is chosen randomly among available challenges. The chosen challenge defines the %letter% and set at random the %index%. Then, the %word% is also pick off randomly from batch of words (see Dictionary).

New captcha

You can create your own captcha. It should extend AbstractCaptcha and it must implement CaptchaInterface, that's it!
