Yii 2 Advanced Project Template is a skeleton Yii 2 application best for developing complex Web applications with multiple tiers.

The template includes three tiers: front end, back end, and console, each of which is a separate Yii application.

The template is designed to work in a team development environment. It supports deploying the application in different environments.

Documentation is at docs/guide/README.md.

REQUIREMENTS ¶

[!IMPORTANT]

• The minimum required PHP version of Yii is PHP 8.2.

Install via Composer ¶

If you do not have Composer, you may install it by following the instructions at getcomposer.org.

You can then install this project template using the following commands:

    views/               contains view files for the Web application
    web/                 contains the entry script and Web resources
    widgets/             contains frontend widgets

Initialize the application for the Development environment:

php init --env=Development --overwrite=All

Now you should be able to access the application through the following URLs, assuming advanced is the directory directly under the Web root.

http://localhost/advanced/frontend/web/
http://localhost/advanced/backend/web/

Install with Docker ¶

Build and start the containers:

docker compose up -d --build

Install dependencies inside the container:

docker compose exec frontend composer update --prefer-dist --no-interaction

Initialize the application for the Development environment:

docker compose exec frontend php /app/init --env=Development --overwrite=All

After running init, update the database connection in common/config/main-local.php to use the mysql service hostname:

'db' => [
    'class' => \yii\db\Connection::class,
    'dsn' => 'mysql:host=mysql;dbname=yii2advanced',
    'username' => 'yii2advanced',
    'password' => 'secret',
    'charset' => 'utf8',
],

You can then access the application through the following URLs:

http://127.0.0.1:20080  (frontend)
http://127.0.0.1:21080  (backend)

To run the test suite, also update common/config/test-local.php to use the mysql hostname and create the test database:

'db' => [
    'dsn' => 'mysql:host=mysql;dbname=yii2advanced_test',
],

docker compose exec -T mysql mysql -uroot -pverysecret -e "CREATE DATABASE IF NOT EXISTS yii2advanced_test; GRANT ALL PRIVILEGES ON yii2advanced_test.* TO 'yii2advanced'@'%'; FLUSH PRIVILEGES;"
docker compose exec -T frontend php /app/yii_test migrate --interactive=0
docker compose exec -T frontend vendor/bin/codecept build
docker compose exec -T frontend vendor/bin/codecept run

NOTES:

• Minimum required Docker engine version 17.04 for development (see Performance tuning for volume mounts)
• The default configuration uses a host-volume in your home directory ~/.composer-docker/cache for Composer caches

CONFIGURATION ¶

Database ¶

Edit the file common/config/main-local.php with real data, for example:

return [
    'components' => [
        'db' => [
            'class' => \yii\db\Connection::class,
            'dsn' => 'mysql:host=localhost;dbname=yii2advanced',
            'username' => 'root',
            'password' => '1234',
            'charset' => 'utf8',
        ],
    ],
];

When using Docker, the MySQL service is pre-configured. Update common/config/main-local.php to use:

'db' => [
    'class' => \yii\db\Connection::class,
    'dsn' => 'mysql:host=mysql;dbname=yii2advanced',
    'username' => 'yii2advanced',
    'password' => 'secret',
    'charset' => 'utf8',
],

Apply migrations:

php yii migrate

Or with Docker:

docker compose exec frontend php /app/yii migrate

NOTES:

• Yii won't create the database for you, this has to be done manually before you can access it. When using Docker, the MySQL service creates the database automatically.
• Check and edit the other files in the config/ directories to customize your application as required.
• Refer to the README in the tests directory for information specific to application tests.

TESTING ¶

Tests are located in frontend/tests, backend/tests, and common/tests directories. They are developed with Codeception PHP Testing Framework.

Tests can be executed by running:

vendor/bin/codecept run --env php-builtin

Or using the Composer script:

composer tests
