Akismet Silverstripe Module

Credits and Authors

Requirements

Installation Instructions

This module can be easily installed on any already-developed website

  • If using composer installation can be done as below
composer require tractorcow/silverstripe-akismet 3.1.x-dev
  • If not using composer you'll need to download the akismet module, spam protector, and akismet

  • Configure your environment to set 'AkismetSpamProtector' as the protector class, and get an API key from akismet.com and set in the site against one of the following ways.

config.yml:

---
Name: myspamprotection
---
FormSpamProtectionExtension:
  default_spam_protector: AkismetSpamProtector
AkismetSpamProtector:
  api_key: 5555dddd55d5d

_config.php:

Config::inst()->update('FormSpamProtectionExtension', 'default_spam_protector', 'AkismetSpamProtector');
AkismetSpamProtector::set_api_key('5555dddd55d5d');

_ss_environment.php:

define('SS_AKISMET_API_KEY', '5555dddd55d5d');
// and set AkismetSpamProtector as your spam protector using one of the above methods

Testing

By default, spam protection is disabled for users with ADMIN priviliges. There is also an option to disable spam protection for all logged in users. In order to disable this for testing purposes, you can temporarily modify these options in your development environment as below:

if(!Director::isLive()) {
	Config::inst()->remove('AkismetSpamProtector', 'bypass_permission');
	Config::inst()->remove('AkismetSpamProtector', 'bypass_members');
}

In order to check that your form is blocking spam correctly, you can always set 'viagra-test-123' as the author and Akismet will always mark this as spam.

Comments

If you're using Comments module you can quickly set akismet to filter these out by adding the CommentSpamProtection extension to the CommentingController

config.yml

CommentingController:
  extensions:
    - CommentSpamProtection

_config.php

CommentingController::add_extension('CommentSpamProtection');

Custom Form Usage

To enable spam protection in your custom forms, call the enableSpamProtection method with your field names mapped to the akismet fields:

$form  = new Form($this, 'Form', $fields, $actions, $validator);
$form->enableSpamProtection(array(
  'mapping' => array(
    'Name' => 'authorName',
    'Email' => 'authorMail',
    'Comments' => 'body'
    )
  )
);

Important notes for those in the EU

Because of the way Akismet works (message, author, and other information sent to a third party) in some countries it's legally necessary to notify and gain the user's permission prior to verification.

To create a checkbox style authorisation prompt for this field set the following configuration option:

config.yml

AkismetSpamProtector:
  require_confirmation: true

_config.php

Config::inst()->update('AkismetSpamProtector', 'require_confirmation', true);
