Gregwar's CaptchaBundle ===================== The `GregwarCaptchaBundle` adds support for a "captcha" form type for the Symfony2 form component. Installation ============ ### Step 1: Download the GregwarCaptchaBundle Ultimately, the GregwarCaptchaBundle files should be downloaded to the 'vendor/bundles/Gregwar/CaptchaBundle' directory. You can accomplish this several ways, depending on your personal preference. The first method is the standard Symfony2 method. ***Using the vendors script*** Add the following lines to your `deps` file: ``` [GregwarCaptchaBundle] git=git://github.com/Gregwar/CaptchaBundle.git target=/bundles/Gregwar/CaptchaBundle ``` Now, run the vendors script to download the bundle: ``` bash $ php bin/vendors install ``` ***Using submodules*** If you prefer instead to use git submodules, then run the following: ``` bash $ git submodule add git://github.com/Gregwar/CaptchaBundle.git vendor/bundles/Gregwar/CaptchaBundle $ git submodule update --init ``` ### Step 2: Configure the Autoloader Now you will need to add the `Gregwar` namespace to your autoloader: ``` php registerNamspaces(array( // ... 'Gregwar' => __DIR__.'/../vendor/bundles', )); ``` ### Step 3: Enable the bundle Finally, enable the bundle in the kernel: ```php add('captcha', 'captcha'); // That's all ! // ... ``` Note that the generated image will be embeded in the HTML document, to avoid dealing with route and subrequests. Options ======= You can define the following type option : * **width**: the width of the captcha image (default=120) * **height**: the height of the captcha image (default=40) * **length**: the length of the captcha (number of chars, default 5) * **as_file**: if set to true an image file will be created instead of embedding to please IE6/7 (default=false) * **image_folder**: name of folder for captcha images relative to public web folder in case **as_file** ist set to true (default="captcha") * **web_path**: absolute path to public web folder (default="%kernel.root_dir%/../web") * **gc_freq**: frequency of garbage collection in fractions of 1 (default=100) * **expiration**: maximum lifetime of captcha image files in minutes (default=60) Example : ```php add('captcha', 'captcha', array( 'width' => 200, 'height' => 50, 'length' => 6, )); ``` You can also set these options for your whole application using the `gregwar_captcha` configuration entry in your `config.yml` file: gregwar_captcha: width: 200 height: 50 length: 6 Form theming ============ The widget support the standard symfony theming, see the [documentation](http://symfony.com/doc/current/book/forms.html#form-theming) for details on how to accomplish this. The default rendering is: ```html {% block captcha_widget %} {% spaceless %} {{ form_widget(form) }} {% spaceless %} {% endblock %} ``` Image creation ============== If you choose to use image files instead of embedding the widget will execute a garbage collection randomly and delete images that exceed the configured lifetime.
