⚠️ DEPRECATED:
Unfortunately I want to inform this bundle is getting deprecated, I recommend using EWZRecaptchaBundle instead. Sorry for the inconvenience. 😔
This bundle provides easy reCAPTCHA form field for Symfony in order to protect your website from spam and abuse.
Installation
Step 1: Using composer and enable the Bundle
To install the bundle via composer, just run from the command line (terminal):
$ composer require vihuvac/recaptcha-bundle
Composer will automatically download all the required files, and install them for you. All that is left to do is to update your AppKernel.php
file, and register the new bundle:
// app/AppKernel.php <?php public function registerBundles() { $bundles = array( // ... new Vihuvac\Bundle\RecaptchaBundle\VihuvacRecaptchaBundle(), ); }
Step 2: Configure the bundle
Add the following to your config file:
# app/config/config.yml vihuvac_recaptcha: site_key: here_is_your_site_key secret_key: here_is_your_secret_key locale_key: kernel.default_locale
NOTE:
This bundle uses a secure API (HTTPS Protocol). Google API solves the requests by the Browser (Client).
The
site_key
parameter is the same than thepublic_key
parameter and thesecret_key
parameter is the same than theprivate_key
parameter (parameters used in the previous versions).
You can easily enable and disable the reCAPTCHA feature using any one of the booleans true
or false
through the enabled parameter, e.g:
# app/config/config.yml vihuvac_recaptcha: // ... enabled: true
If you want to use the language used by the locale request as the language for the reCAPTCHA, you must activate the resolver (deactivated by default):
# app/config/config.yml vihuvac_recaptcha: // ... locale_from_request: true
You can load the reCAPTCHA using the Ajax API (optional):
# app/config/config.yml vihuvac_recaptcha: // ... ajax: true
Additionally you can add HTTP Proxy configuration (optional):
# app/config/config.yml vihuvac_recaptcha: // ... host: proxy.your-domain.com port: 3128 auth: proxy_username:proxy_password
In case you have turned off the domain name checking on reCAPTCHA's end, you'll need to check the origin of the response by enabling the verify_host
option:
# app/config/config.yml vihuvac_recaptcha: // ... verify_host: true
Congratulations! You're ready!
Basic Usage
When creating a new form class add the following line to create the field:
Symfony and PHP Reference
<?php public function buildForm(FormBuilder $builder, array $options) { // ... $builder->add("recaptcha", "vihuvac_recaptcha"); // ... }
Symfony and PHP Reference
Note:
To denote the form type, you have to use the fully qualified class name - like
TextType::class
in PHP 5.5+ orSymfony\Component\Form\Extension\Core\Type\TextType
. Before Symfony 2.8, you could use an alias for each type liketext
ordate
. The old alias syntax will still work until Symfony 3.0. For more details, see the 2.8 UPGRADE Log.
<?php use Vihuvac\Bundle\RecaptchaBundle\Form\Type\VihuvacRecaptchaType as RecaptchaType; public function buildForm(FormBuilder $builder, array $options) { // ... $builder->add("recaptcha", RecaptchaType::class); // ... }
You can pass extra options to reCAPTCHA with the attr > options
option, e.g:
<?php use Vihuvac\Bundle\RecaptchaBundle\Form\Type\VihuvacRecaptchaType as RecaptchaType; public function buildForm(FormBuilder $builder, array $options) { // ... $builder->add("recaptcha", RecaptchaType::class, array( "attr" => array( "options" => array( "theme" => "light", "type" => "audio", "size" => "normal", "defer" => false, // Set true if you want to use the Ajax API. "async" => false // Set true if you want to use the Ajax API. ) ) )); // ... }
reCAPTCHA tag attributes and render parameters:
Support Google's Invisible reCAPTCHA! It's super easy:
<?php use Vihuvac\Bundle\RecaptchaBundle\Form\Type\VihuvacRecaptchaType as RecaptchaType; public function buildForm(FormBuilder $builder, array $options) { // ... $builder->add("recaptcha", RecaptchaType::class, array( "attr" => array( "options" => array( "theme" => "light", "type" => "image", "size" => "invisible", // Set size to the invisible reCAPTCHA. "defer" => false, // Set true if you are using the Ajax API. "async" => false, // Set true if you are using the Ajax API. "callback" => "onReCaptchaSuccess", // Callback will be set by default if it's not defined (along with JS function that validates the form on success). "bind" => "buttonSubmit", // This is the form submit button id (html attribute). // ... ) ) )); // ... }
Note: If you use the pre-defined callback, you would need to add
recaptcha-form
class to your<form>
tag.
If you need to configure the language for the reCAPTCHA depending on your site language (ideal for multi-language sites) you can pass the language with the "language" option:
<?php use Vihuvac\Bundle\RecaptchaBundle\Form\Type\VihuvacRecaptchaType as RecaptchaType; public function buildForm(FormBuilder $builder, array $options) { // ... $builder->add("recaptcha", RecaptchaType::class, array( "language" => "en", // ... )); // ... }
To validate the field use:
<?php use Vihuvac\Bundle\RecaptchaBundle\Validator\Constraints as Recaptcha; /** * @Recaptcha\IsTrue */ public $recaptcha;
Another method would consist to pass the validation constraints as an options of your FormType. This way, your data class contains only meaningful properties.
If we take the example from above, the buildForm method would look like this.
Please note that if you set mapped => false
then the annotation will not work. You have to also set constraints
:
<?php use Vihuvac\Bundle\RecaptchaBundle\Form\Type\VihuvacRecaptchaType as RecaptchaType; use Vihuvac\Bundle\RecaptchaBundle\Validator\Constraints\IsTrue as RecaptchaTrue; public function buildForm(FormBuilder $builder, array $options) { // ... $builder->add("recaptcha", RecaptchaType::class, array( "attr" => array( "options" => array( "theme" => "light", "type" => "audio", "size" => "normal" ) ), "mapped" => false, "constraints" => array( new RecaptchaTrue() ) )); // ...
Cool! The form template resource is now auto registered via container extension. However, you can always implement your own custom form widget:
PHP:
<?php $view["form"]->setTheme($form, array("VihuvacRecaptchaBundle:Form")) ?> <?php echo $view["form"]->widget($form["recaptcha"], array( "attr" => array( "options" => array( "theme" => "light", "type" => "audio", "size" => "normal" ) ) )) ?>
Twig:
{% form_theme form "VihuvacRecaptchaBundle:Form:vihuvac_recaptcha_widget.html.twig" %} {{ form_widget( form.recaptcha, { "attr": { "options": { "theme": "light", "type": "audio", "size": "normal" }, } } ) }}
If you are not using a form, you can still implement the reCAPTCHA field using JavaScript:
PHP:
<div id="recaptcha-container"></div> <script type="text/javascript"> $(document).ready(function() { $.getScript("<?php echo \Vihuvac\Bundle\RecaptchaBundle\Form\Type\VihuvacRecaptchaType::RECAPTCHA_API_JS_SERVER ?>", function() { Recaptcha.create("<?php echo $form['recaptcha']->get('site_key') ?>", "recaptcha-container", { theme: "light", type: "audio", "size": "normal" }); }); }; </script>
Twig:
<div id="recaptcha-container"></div> <script type="text/javascript"> $(document).ready(function() { $.getScript("{{ constant('\\Vihuvac\\Bundle\\RecaptchaBundle\\Form\\Type\\VihuvacRecaptchaType::RECAPTCHA_API_JS_SERVER') }}", function() { Recaptcha.create("{{ form.recaptcha.get('site_key') }}", "recaptcha-container", { theme: "light", type: "audio", "size": "normal" }); }); }); </script>
Customization:
If you want to use a custom theme, put your chunk of code before setting the theme:
<div id="recaptcha_widget"> <div id="recaptcha_image"></div> <div class="recaptcha_only_if_incorrect_sol" style="color:red">Incorrect please try again</div> <span class="recaptcha_only_if_image">Enter the words above:</span> <span class="recaptcha_only_if_audio">Enter the numbers you hear:</span> <input type="text" id="recaptcha_response_field" name="recaptcha_response_field" /> <div><a href="javascript:Recaptcha.reload()">Get another CAPTCHA</a></div> <div class="recaptcha_only_if_image"><a href="javascript:Recaptcha.switch_type("audio")">Get an audio CAPTCHA</a></div> <div class="recaptcha_only_if_audio"><a href="javascript:Recaptcha.switch_type("image")">Get an image CAPTCHA</a></div> <div><a href="javascript:Recaptcha.showhelp()">Help</a></div> </div> {% form_theme form "VihuvacRecaptchaBundle:Form:vihuvac_recaptcha_widget.html.twig %} {{ form_widget( form.recaptcha, { "attr": { "options" : { "theme" : "custom", }, } } ) }}

Tests
Execute this command to run tests:
$ cd recaptcha-bundle/
$ ./vendor/bin/phpunit
Note: If you are running tests only and within the bundle, as first step you should run
composer install
in order to install the required dependencies. Then you'll be able to run the tests!
