Features

• Cookie Consent Manager
• Data retention

Cookie Consent Manager

This plugin provides two simple components to make your October installation GDPR compliant.

Quick start

1. Define your cookie groups and cookies via the backend settings page. You can also import a example preset by running php artisan gdpr:import
2. Place the cookieManager component on a cookies.htm page
3. Place the cookieBanner component on all of your layouts. Use the configuration listed below.

[cookieBanner]
include_css = 1
update_partial = "gdpr"
update_selector = "#gdpr-reload"
cookie_manager_page = "cookies"
==
{% component 'cookieBanner' %}

1. Create a new gdpr.htm partial. Include the partial in your layouts as shown below. Note the #gdpr-reload wrapper.

<div id="gdpr-reload">
    {% partial 'gdpr' %}
</div>

1. Inside your gdpr.htm partial you can now conditionally include your dependencies by querying the cookie's code.

{% if gdprCookieAllowed('google-analytics') %}
    <!-- Include analytics code here -->
{% endif %}

Cookie manager

The cookieManager component gives a visitor more control over the cookies your site is using.

This component can simply be placed on a page and needs no further configuration.

title = "Cookies"
url = "/cookies"
layout = "default"
is_hidden = 0

[cookieManager]
==
{% component 'cookieManager' %}

Cookie presets

It is possible to define your cookie groups and cookies in a yaml file and import them using the gdpr:import console command. This allows you to define cookies once and re-use them between installations.

php artisan gdpr:import --path=plugins/offline/gdpr/assets/presets/example_en.yaml --replace

You can find example definitions in the assets/presets directory of this plugin.

You can optionally use the --replace flag to remove all existing cookie data and replace it with your preset.

If no path is specified, the plugin will load all presets from the configured presets_path and ask you which preset to import.

You can change the path where presets are loaded from by changing the offline.gdpr::config.presets_path config entry. To do this, create the file config/offline/gdpr/config.php and return your custom path:

<?php
return [
    'presets_path' => '/path/to/your/presets',
];

cookieBanner

The cookieBanner component displays a cookie banner on the first page view. There the user has the possibility to enable and disable cookies that your website uses (defined via October's backend settings).

These settings are stored and made available in your partials using the gdprCookieAllowed helper. With this helper you can check for the user's consent and optionally include your resources.

Installation

1. Define your cookie groups and cookies via the Backend settings
2. Add the cookieBanner component to all your layouts.

[cookieBanner]
include_css = 1
update_partial = "gdpr"
update_selector = "#gdpr-reload"
cookie_manager_page = "cookies"
==
{% component 'cookieBanner' %}

Log

You can enable a log via the backend settings so every cookie banner request gets logged. This is useful to get an idea of the number of users that do not accept a cookie request and therefore never end up in your analytics data.

The log only contains the user's session id and their decision.

Properties

If you don't want to include the default css use include_css = 0 when including your component.

cookieManager page

Set the property cookie_manager_page to the page that contains the cookieManager component.

A Advanced Settings link will be placed on the cookieBar that links to this page. This enables the user to further define what cookies are allowed.

Twig Helpers

gdprCookieAllowed($code, $minLevel = 0)

Check if a certain cookie is allowed to be included. You can optionally pass a cookie level to check if the user has accepted a specific level of this cookie.

{% if gdprCookieAllowed('google-analytics') %}
    <!-- Include Analytics Code here -->
{% endif %}

{% if gdprCookieAllowed('google-analytics', 3) %}
    <!-- Include advanced Level 3 Analytics Code here -->
{% endif %}

gdprAllowedCookieLevel($code)

Get the max allowed level for a certain cookie. A return value of -1 means the cookie is not allowed at all. A value of 0 or higher means the cookie is allowed with the returned level value.

{% if gdprAllowedCookieLevel('google-analytics') >= 3 %}
    <!-- Include advanced Level 3 Analytics Code here -->
{% endif %}

gdprIsUndecided()

Check if the user has made a decision about the cookies yet. This will return true on the second page view if the user did not interact with the cookieBanner (silent opt-in).

Data retention

The data retention functionality enables you to delete old plugin data after a specified amount of days.

You can specify the data retention policy for each plugin via October's backend settings.

Important: To automatically delete old data make sure you have set up the Task Scheduler correctly.

Register your plugin

To register your plugin you have to listen for the offline.gdpr::cleanup.register event in your Plugin's boot method.

    public function boot()
    {
        \Event::listen('offline.gdpr::cleanup.register', function () {
            return [
                'id'     => 'your-contact-form-plugin',
                'label'  => 'Custom Contact Form Plugin',
                'models' => [
                    [
                        'label'   => 'Contact form messages',
                        'comment' => 'Delete logged contact form messages',
                        'class'   => MessageLog::class,
                    ],
                    [
                        'id'      => 'vendor-plugin-spam-messages',  // The ID is required if you specify a closure. This should be unique to your plugin.
                        'label'   => 'SPAM-Messages',
                        'comment' => 'Delete blocked SPAM messages',
                        'closure' => function (Carbon $deadline, int $keepDays) {
                            // Delete your old data here
                        },
                    ],
                ],
            ];
        });
    }

You have to specify the following data:

key	information
id	A unique identifier of your plugin
label	A human readable label for your plugin
models	An array of all your data collecting models

As models you have to specify an array with the following data:

key	information
id	A unique string to identify this model. Use only _-a-z0-9. Only required if you specify a closure. (ex. offline-gdpr-spam-messages)
label	A human readable label for the backend switch form widget
comment	A human readable comment for the backend switch form widget
closure	A closure that is called when the cleanup job is run. Make sure to also define an id.
class	A model class that defines a gdprCleanup method

You have to specify either a closure or a class value. If both are specified the closure value will be used.

Cleanup method

You can either specify a closure or a model class that defines a gdprCleanup method. Both have the same signature:

    public function gdprCleanup(\Carbon\Carbon $deadline, int $keepDays)
    {
        self::where('created_at', '<', $deadline)->each(function (self $item) {
            $item->delete();
        });
        // or
        // self::where('created_at', '<', $deadline)->delete();
    }

This method is called whenever the cleanup job is run. $deadline contains a Carbon instance. All data older than this date has to be deleted. $keepDays contains the number of days that $deadline is in the past.

Make sure to use an each/delete loop if your model makes use of deleting/deleted model events.

Cleanup command

You can trigger the cleanup on demand via

php artisan gdpr:cleanup
