if you use basic template, you can still use the same code above, just put the code in you config file and change baseFrontendUrl. You can remove or comment baseBackendUrl

Controllers

add UploadFile in your controller

use yii\web\UploadedFile;

single image upload

In your controller action :

$upload = new Yii::$app->uploaders();

/**
If you want to use backend path:
$upload = new Yii::$app->uploaders("backend");
**/

$model->image =  $upload->upload(UploadedFile::getInstance($model, 'image'), "avatars");

$model->image now have the name of the uploaded image, ready to save it in database.

multiple uploads

foreach (UploadedFile::getInstances($model, 'image') as $file) {
    $model->image = (new Yii::$app->uploaders())->upload($file, "avatars");

}

upload from url

Now it is possible to upload images from other website, using dynamic or static urls. the same code can be used in a loop

 $model->image = $upload->uploadFromUrl("https://www.website.it/url/to/image/image.jpg",  "myFolder");

N.B. no need upload instance

infinite folders generation

You can make infinite folders. For example with user id: images/user/3/1200/imagename.jpg

$model->image =  $upload->upload(UploadedFile::getInstance($model, 'image'), "users/".Yii::$app->user->id);

in your view

do not forget to use multipart/form-data to your form

<?php $form = ActiveForm::begin([
    'options' => ['enctype'=>'multipart/form-data']
]); ?>

Delete images from folder

If you need to delete one or more images from all folders:

( new Yii::$app->uploaders() )->delete( file, folder );

for example:

 (new Yii::$app->uploaders())->delete($model->name, "/products/".Yii::$app->user->id);

It remove all images in your path/products/user id/others setted folder/file
