Introduction of EU Cookie Compliance in Drupal

Cookies are integral to modern websites, enabling features like personalization and analytics. However, with the growing emphasis on privacy, the EU’s General Data Protection Regulation (GDPR) and related regulations demand explicit user consent for cookies. For Drupal developers, implementing cookie compliance involves utilizing tools and techniques to ensure that cookies are not set or scripts executed without user approval. This article explores how to achieve EU cookie compliance in Drupal using built-in modules and custom solutions.

Understanding EU Cookie Compliance and GDPR

The GDPR imposes strict rules on how cookies are managed:

• Transparency: Websites must inform users about cookies and their purpose.

• Consent: Users must give explicit permission before cookies are stored.

• Control: Users should have the ability to accept, reject, or revoke cookie permissions at any time.

Why These Rules Exist?

• To protect user data and online privacy.

• To ensure users are aware of how their information is collected and used.

Implementing Cookie Compliance in Drupal

Drupal’s EU Cookie Compliance module provides a structured way to comply with GDPR. Here’s how to use it effectively:

1. Install and Configure the EU Cookie Compliance Module

Install the module via Composer:

composer require drupal/eu_cookie_compliance

Enable the module in the Drupal admin interface.

Configure settings:

Set consent types (opt-in, opt-out, or both).

Customize the cookie banner text and design to match the website’s branding.

2. Using hasAgreed() for Conditional Scripts and Cookies

The module provides the hasAgreed() JavaScript function to check user consent status:

Example Usage in Google Analytics:

if (!Drupal.eu_cookie_compliance.hasAgreed()) {
window['ga-disable-UA-xxxx-1'] = true;
}

Add this code in Advanced Settings -> Custom JS to prevent Google Analytics from running without consent.

3. Creating a Custom Module for Advanced Scenarios

If strict compliance is necessary, a custom module also may be necessary:

Step 1: Remove Non-Compliant Scripts

Replace scripts with placeholders in the template (e.g., html.html.twig):

<div id="analytics-placeholder"></div>

Step 2: Load Scripts Conditionally

Use hasAgreed() in a custom JavaScript behavior to load scripts only after consent:

Drupal.behaviors.customCookieConsent = {
attach: function (context, settings) {
if (Drupal.eu_cookie_compliance.hasAgreed()) {
// Inject third-party script
var script = document.createElement('script');
script.src = 'https://example.com/analytics.js';
document.getElementById('analytics-placeholder').appendChild(script);
}
},
};

4. Granular Consent Management

For websites with multiple types of cookies (e.g., analytics, marketing), implement granular consent options:

Use the EU Cookie Compliance module’s built-in settings for separate cookie categories.

Provide detailed descriptions of each category to ensure user transparency.

Best Practices for GDPR Cookie Compliance in Drupal

• Transparency: Always disclose how cookies are used in the privacy policy.

• Granular Consent: Allow users to manage consent for different cookie types.

• Accessibility: Ensure cookie banners and controls are accessible to all users.

• Regular Updates: Keep the compliance mechanisms aligned with evolving regulations.
