Usage
-----

[](#usage)

### Prepare

[](#prepare)

Add migration to create table for images:

```
class m150318_154933_gallery_ext
    extends coolanole\yii2\galleryManager\migrations\m140930_003227_gallery_manager
{

}
```

Or better - copy migration to you application(but be sure to **remove namespace from it** - it should be in global namespace)

### Add configurations for upload and store images

[](#add-configurations-for-upload-and-store-images)

Add GalleryBehavior to your model, and configure it, create folder for uploaded files.

```
use coolanole\yii2\galleryManager\GalleryBehavior;

class Product extends \yii\db\ActiveRecord
{
...
public function behaviors()
{
    return [
         'galleryBehavior' => [
             'class' => GalleryBehavior::className(),
             'type' => 'product',
             'extension' => 'jpg',
             'directory' => Yii::getAlias('@webroot') . '/images/product/gallery',
             'url' => Yii::getAlias('@web') . '/images/product/gallery',
             'versions' => [
                 'small' => function ($img) {
                     /** @var \Imagine\Image\ImageInterface $img */
                     return $img
                         ->copy()
                         ->thumbnail(new \Imagine\Image\Box(200, 200));
                 },
                 'medium' => function ($img) {
                     /** @var \Imagine\Image\ImageInterface $img */
                     $dstSize = $img->getSize();
                     $maxWidth = 800;
                     if ($dstSize->getWidth() > $maxWidth) {
                         $dstSize = $dstSize->widen($maxWidth);
                     }
                     return $img
                         ->copy()
                         ->resize($dstSize);
                 },
             ]
         ]
    ];
}
```

See also [documentations of imagine](https://imagine.readthedocs.io/en/master/usage/introduction.html) for image transformations.

Add GalleryManagerAction in controller somewhere in your application. Also on this step you can add some security checks for this action.

```
use coolanole\yii2\galleryManager\GalleryManagerAction;

class ProductController extends Controller
{
...
public function actions()
{
    return [
       'galleryApi' => [
           'class' => GalleryManagerAction::className(),
           // mappings between type names and model classes (should be the same as in behaviour)
           'types' => [
               'product' => Product::className()
           ]
       ],
    ];
}
```

Add ImageAttachmentWidget somewhere in you application, for example in editing from.

```
use coolanole\yii2\galleryManager\GalleryManager;

/* @var $this yii\web\View */
/* @var $model Product */
?>
