Contao 4 core bundle

Contao is an Open Source PHP Content Management System for people who want a professional website that is easy to maintain. Visit the project website for more information.

Contao 4 has been designed as a Symfony bundle, which can be used to add CMS functionality to any Symfony application. If you do not have an existing Symfony application yet, we recommend using the Contao managed edition as basis for your application.

Prerequisites

The Contao core bundle has a recipe in the symfony/recipes-contrib repository. Be sure to either enable contrib recipes for your project by running the following command or follow the instructions to use the contrib recipe during the installation process.

composer config extra.symfony.allow-contrib true

Add the contao-component-dir to the extra section of your composer.json file.

composer config extra.contao-component-dir assets

Installation

Install Contao and all its dependencies by executing the following command:

composer require \
    contao/core-bundle:4.8.* \
    php-http/guzzle6-adapter:^1.1

Note that you can exchange the php-http/guzzle6-adapter package with any other HTTP client implementation. If you already have an HTTP client implementation, you can omit the package entirely.

Configuration

Configure the DATABASE_URL in your environment, either using environment variables or by using the Dotenv component.

Enable ESI in the config/packages/framework.yaml file.

framework:
    esi: true

Add the Contao routes to your config/routing.yaml file, and be sure to load the ContaoCoreBundle at the very end, so the catch-all route does not catch your application routes.

ContaoCoreBundle:
    resource: "@ContaoCoreBundle/config/routes.yaml"

Edit your config/security.yaml file and merge all the providers, encoders, firewalls and access_control sections:

security:
    password_hashers:
        Contao\User: auto

    providers:
        contao.security.backend_user_provider:
            id: contao.security.backend_user_provider

        contao.security.frontend_user_provider:
            id: contao.security.frontend_user_provider

    firewalls:
        contao_backend:
            request_matcher: contao.routing.backend_matcher
            provider: contao.security.backend_user_provider
            user_checker: contao.security.user_checker
            switch_user: true

            contao_login:
                remember_me: false

            logout:
                path: contao_backend_logout

        contao_frontend:
            request_matcher: contao.routing.frontend_matcher
            provider: contao.security.frontend_user_provider
            user_checker: contao.security.user_checker
            switch_user: false

            contao_login:
                remember_me: true

            remember_me:
                secret: '%kernel.secret%'
                remember_me_parameter: autologin
                service: contao.security.persistent_remember_me_handler

            logout:
                path: contao_frontend_logout

    access_control:
        - { path: ^%contao.backend.route_prefix%/login$, roles: PUBLIC_ACCESS }
        - { path: ^%contao.backend.route_prefix%/logout$, roles: PUBLIC_ACCESS }
        - { path: ^%contao.backend.route_prefix%(/|$), roles: ROLE_USER }
        - { path: ^/, roles: [PUBLIC_ACCESS] }

The Contao core-bundle is now installed and activated. Use the contao:migrate command to upgrade the database and the contao:user:create command to create your first back end user.
