Requirements

PHP 8.4+
Symfony 8.0+
Twig Bundle, Security Bundle, Stimulus Bundle
Doctrine ORM + DoctrineBundle (optional, only for storage: doctrine|both)

Compatibility

Bundle Version	PHP	Symfony
0.4.x	8.4+	8.0+
0.3.x	8.3+	7.1+
0.2.x	8.2+	7.0+

Quick Start

1. Install

composer require jostkleigrewe/cookie-consent-bundle

2. Register routes

Create config/routes/cookie_consent.yaml:

cookie_consent:
    resource: '@CookieConsentBundle/config/routes.php'

This registers the /_cookie-consent endpoint required for consent updates.

3. Configure assets

Option A: Twig helper (CSP-compatible, recommended)

{# templates/base.html.twig - in <head> #}
{{ cookie_consent_styles() }}

This renders a standard <link> tag, fully compatible with strict Content-Security-Policy headers.

Option B: JavaScript import

// assets/app.js
import '@jostkleigrewe/cookie-consent-bundle/styles/cookie_consent.css';

Note: With strict CSP (style-src 'self'), bundlers may convert CSS imports to data: URLs, which can be blocked. Use Option A if you encounter CSP issues.

// assets/controllers.json
{
  "controllers": {
    "@jostkleigrewe/cookie-consent-bundle": {
      "cookie-consent": { "enabled": true, "fetch": "eager" }
    }
  }
}

4. Render the modal

{# templates/base.html.twig #}
{{ cookie_consent_modal() }}

5. Gate content by consent

{% if cookie_consent_has('analytics') %}
  <script src="https://example.com/analytics.js"></script>
{% endif %}

Or use lazy loading:

<script type="text/plain" data-consent-category="analytics"
        data-consent-src="https://example.com/analytics.js"></script>

Configuration

Create config/packages/cookie_consent.yaml:

cookie_consent:
  policy_version: '1'
  storage: cookie  # cookie, doctrine, or both

  categories:
    necessary:
      label: Necessary
      required: true
      default: true
    analytics:
      label: Analytics
      default: false
    marketing:
      label: Marketing
      default: false
      vendors:
        google_ads:
          label: Google Ads
          default: false

  ui:
    template: '@CookieConsent/styles/tabler/modal.html.twig'
    position: center
    privacy_url: '/privacy'
    reload_on_change: false

  logging:
    retention_days: null

  google_consent_mode:
    enabled: false

Storage Modes

Mode	Description	Use Case
`cookie`	Browser cookie only (default)	Simple sites, no DB required
`doctrine`	Database only via Doctrine ORM	Server-side consent verification
`both`	Cookie + Database (cookie as primary, DB as backup)	Full audit trail + fast access

If storage is set to doctrine or both, generate migrations in your app (bundle ships entities, not migrations). This requires Doctrine ORM:

bin/console doctrine:migrations:diff
bin/console doctrine:migrations:migrate

Increment policy_version when changing categories to require re-consent.

If logging.retention_days is set, run the cleanup command regularly:

bin/console cookie-consent:cleanup

Integration Overview

See Integration for Twig components, helpers, data attributes, controller attributes, and events.

Troubleshooting

Modal doesn't appear

Ensure {{ cookie_consent_modal() }} is in your base template
Check browser console for JavaScript errors
Verify Stimulus controller is loaded: @jostkleigrewe/cookie-consent-bundle/cookie-consent

Assets not loading (404)

Run bin/console cache:clear
Check AssetMapper paths: bin/console debug:asset-map | grep cookie
Ensure assets/app.js imports the CSS

Session cookie created before consent

Check enforcement.require_consent_for_session is true
Add routes to stateless_routes if they should work without session
Verify #[ConsentStateless] attribute on stateless controllers

Doctrine storage not working

Run migrations: bin/console doctrine:migrations:diff && bin/console doctrine:migrations:migrate
Check storage: doctrine or storage: both is set
Verify doctrine/orm and doctrine/doctrine-bundle are installed

Google Consent Mode not updating

Ensure google_consent_mode.enabled: true
Check gtag is loaded before the consent modal
Verify category mapping matches your categories

Tabler variant styling issues (missing border-radius, labels below checkbox)

Cause: Tabler loads after bundle CSS and overrides .modal-content and form-switch styles
Solution: Update to latest bundle version (>= 0.4.2) which includes Tabler-specific fixes
Manual fix: Add to your CSS with higher specificity:

.cookie-consent-modal.cookie-consent-variant-tabler .modal-content {
    border: 0;
    border-radius: var(--cc-radius, 18px);
    box-shadow: var(--cc-shadow, 0 24px 60px rgba(15, 23, 42, 0.25));
}
.cookie-consent-variant-tabler .cookie-consent-toggle.form-switch {
    display: block;
    padding-left: 2.5rem;
}
.cookie-consent-variant-tabler .cookie-consent-toggle.form-switch .form-check-input {
    float: left;
    margin-left: -2.5rem;
}
