Digipolis Cookiebot

Adds extra functionality to the Cookiebot module.

The City of Ghent has opted for Cookiebot to allow visitors to approve loading of (third party) party cookies.

This module extends the Cookiebot module with extra functionality:

• A placeholder filter to add the Cookiebot declaration into formatted text.

Installation

Add the git source to the composer repositories: edit composer.json in the project root and add following lines in the repositories section:

{
    "type": "composer",
    "url": "https://digipolis.repo.repman.io"
}

Add the following Cookiebot module patches to:

• Have Cookiebot respect the language of the current page.
• Fix Cookiebot auto blocking breaking Drupal core Domready functionality.

"drupal/cookiebot": {
    "#3071334 Allow to set the language and multilingual support": "https://www.drupal.org/files/issues/2019-10-29/cookiebot-allow_to_set_the_language-3071334-8.patch",
    "#3091260 Blockmode `Auto` will not work with core's domready library": "https://www.drupal.org/files/issues/2020-01-29/cookiebot-attach_behaviors-3091260-30.patch"
},

Install the module using composer:

composer require gent-drupal/dg_cookiebot

Enable the module:

drush -y en dg_cookiebot

Update the Cookiebot configuration at admin/config/cookiebot:

• Enter the Cookiebot Domain Group ID (CBID).
• Enable the Automatically block all cookies checkbox.
• Enable the Use the current Drupal language checkbox.
• Enable the Exclude admin pages checkbox.

It's possible to overwite the Cookiebot Domain Group ID (CBID) in the settings.php file:

/**
 * Cookiebot.
 */
$config['cookiebot.settings']['cookiebot_cbid'] = 'COOKIEBOT DOMAIN GROUP ID';

Link to edit the Cookie consent

Once the user has set his cookie consent he has by default no link to review/edit his consent.

Menu item

Add a menu item (e.g. to the footer menu) to update the cookie consent. The path of the menu item should be /cookiebot-renew. It will be automatically rewritten to trigger the cookie consent popup.

Use block

There is a "Cookie settings link" block available to add the Cookie consent link to a region on the website.

Custom link

It's always possible to add a custom link to trigger opening the cookie consent popup:

<a href="javascript:Cookiebot.renew()">Update cookie consent</a>

Create cookie declaration page

This module adds a filter to replace a token within formatted text content by the proper javascript tag to load the Cookie Declaration (list of cookies used within the website).

Add the text filter

• Open /admin/config/content/formats and configure the text format where the token should be used.
• Enable the "Replace Cookiebot declaration placeholder" filter.
• Make sure that the filter is the last one in the list.

Create the Cookie declaration page

• Create a new page on the path /cookie-declaration.
• Add to the content (formatted text) the [COOKIEBOT_DECLARATION] placeholder where the list of cookies in use should be displayed.

Update Cookiebot configuration

The cookie consent popup is by default loaded on all page, also on the page containing the cookie declaration. Add this page to the excluded paths.

• Open the Cookiebot configuration on admin/config/cookiebot.
• Add /cookie-declaration to the "Exclude paths".

The Cookies declartion will now be loaded on the /cookie-declaration page.

Video without cookies

Services like Youtube and Vimeo provide by default iframes that track the users with cookies. They provide a no-cookie domain but that is not wat is used by default.

To avoid loading this iframes and the cookies that come with them, Cookiebot removes the iframe content until the visitor has allowed marketing cookies.

This is how video's can be embeded without cookies:

Patch the video_embed_field module

Add patches to the video_embed_field module so is has an option to embed video without cookies:

    "drupal/video_embed_field": {
      "#2998257 Provide 'do not track' option for vimeo": "https://www.drupal.org/files/issues/2019-02-18/video_embed_field_2998257_5.patch",
      "#2973246 Youtube Privacy Enhanced Mode": "https://www.drupal.org/files/issues/2019-06-08/video_embed_field_youtube_nocookie_2973246_41.patch"
    },

Open the admin/config/media/video-embed-field page and change the "Privacy mode" to "Enabled".

This module will set the proper consent category to the video embed iframes so they will no longer be blocked.
