Installation:

The preferred way to install this extension is through composer., _(*2)

Either run, _(*3)

or add, _(*5)

"aquy/yii2-gallery-manager": "*", _(*6)

to the require section of your composer.json file., _(*7)

Usage

Add migration to create table for images:, _(*8)

class m150318_154933_gallery_ext
    extends aquy\gallery\migrations\m140930_003227_gallery_manager
{

}

Or better - copy migration to you application., _(*9)

Add GalleryBehavior to your model, and configure it, create folder for uploaded files., _(*10)

public function behaviors()
{
    return [
         'galleryBehavior' => [
             'class' => GalleryBehavior::className(),
             'type' => 'product',
             'directory' => Yii::getAlias('@webroot') . '/images/product/gallery',
             'url' => Yii::getAlias('@web') . '/images/product/gallery',
         ]
    ];
}

Add GalleryManagerAction in controller somewhere in your application. Also on this step you can add some security checks for this action., _(*11)

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., _(*12)

if ($model->isNewRecord) {
    echo 'Can not upload images for new record';
} else {
    echo GalleryManager::widget(
        [
            'model' => $model,
            'behaviorName' => 'galleryBehavior',
            'apiRoute' => 'product/galleryApi',
            'async' => false
        ]
    );
}

Done!, _(*13)

Now, you can use uploaded images from gallery like following:, _(*14)

foreach($model->getBehavior('galleryBehavior')->getImages() as $image) {
    echo Html::img($image->getUrl());
}

or, _(*15)

$image = $model->getBehavior('galleryBehavior')->getImage()
echo Html::img($image->getUrl());

Options

Using non default table name for gallery images(default is {{%gallery_image}}):

1. Add migration that will create table you need
2. Change tableName property in behavior configuration
