This bundle provides some basic features to reduce spam in symfony.

Installation

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

composer require core23/antispam-bundle

Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in bundles.php file of your project:

// config/bundles.php

return [
    // ...
    Core23\AntiSpamBundle\Core23AntiSpamBundle::class => ['all' => true],
];

Usage

Form based protection

Create a form on the fly:

$this->createForm(CustomFormType:class, null, array(
    // Time protection
    'antispam_time'     => true,
    'antispam_time_min' => 10,
    'antispam_time_max' => 60,
    
    // Honeypot protection
    'antispam_honeypot'       => true,
    'antispam_honeypot_class' => 'hide-me',
    'antispam_honeypot_field' => 'email-repeat',
));

Twig text protection

{# Replace plain text #}
{{ text|antispam }}

{# Replace rich text mails #}
{{ htmlText|antispam(true) }}

If you want a JavaScript decoding for the encoded mails, you should use the AntiSpam.js library:

$(document).ready(function () {
  new AntiSpam('.custom_class');
});

It is recommended to use webpack / webpack-encore to include the JavaScript library in your page. These file is located in the assets folder.

Global protection

Add protection to all forms using the configuration:

# config/packages/core23_antispam.yaml

core23_antispam:
    # Time protection
    time:
        global: true
        
    # Honeypot protection
    honeypot:
        global: true

Configure the Bundle

Create a configuration file called core23_antispam.yaml:

# config/packages/core23_antispam.yaml

core23_antispam:
    # Twig mail filter
    twig:
        mail:
            css_class: 'custom_class'
            at_text:   [ '[DOT]', '(DOT)', '[.]' ]
            dot_text:  [ '[AT]', '(AT)', '[ÄT]' ]
        
    # Time protection
    time:
        min: 5
        max: 3600
        global: false
        
    # Honeypot protection
    honeypot:
        field: 'email_address'

        provider: 'core23_antispam.provider.session'
