FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package recaptcha

Recaptcha for PHP

Recaptcha for PHP provides a full-featured PHP implementation of the Google reCAPTCHA API along with some helpful adapters for other popular packages. It specifically uses the "no CAPTCHA" version released in December 2014.

Installation

Via Composer:
composer require wowe/recaptcha:1.*

Configuration

Only two values are required to use the package:

Both of these values must be acquired from Google. Directions on how to do so may be found here.

Usage

Setup

In order to use the package, create a new instance of the Recaptcha class, passing in the secret and siteKey values.

Available Methods

Verification Error Codes

After calling verify you may call errors to get a list of any errors that may have been encountered. If any empty array is returned then there were no errors! If there are errors, they will most often be error codes returned by the Google API. In addition to those it may also return:

Adapters

Twig

Website | GitHub
The script and widget methods can be exposed in Twig templates by adding an instance of the included TwigExtension class to the Twig environment. The TwigExtension instance must be initialized with an instance of the Recaptcha class. script is mapped to a function called recaptchaScript and widget is mapped to a function called recaptchaWidget. All arguments are the same as the definitions above.

Slim Framework

Website | GitHub
The Recaptcha class can be registered as a singleton in the Slim container automatically by running the SlimManager::register method, which has three optional arguments:

If you would like to instantiate the Recaptcha class yourself (in order to get the configuration values customly), you may do so and then just pass it to the register method. If no Recaptcha instance is passed then it will attempt to create one by getting the configuration values from the Slim app. In order to take advantage of this, set the configuration value recaptcha to an array with the secret and siteKey values as in the following example:

If a value of true is passed as the registerViewExtension and a view engine is being used which has an extension available (eg. Twig), it will register the corresponding extension with the view engine.
