Image

Image module for my dockerized Yii2 application.

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist acid23m/yii2-image "~1.0"

or add

"acid23m/yii2-image": "~1.0"

to the require section of your composer.json file.

Usage

Once the extension is installed, do next:

  • Storage path is not editable - @root/userdata/images. Add userdata/ to .gitignore.

  • Add module (recommended id is imagetool) in backend/config/main.php and frontend/config/main.php.

'modules' => [
    'imagetool' => [
        'class' => \imagetool\Module::class,
        'controllerNamespace' => 'imagetool\controllers\web',
        //'browser_cache_time' => 60,
        //'etag' => true,
        //'unset_cookie' => true,
    ]
]
