$randomString = "";
$length = 10;
$character = "QWERTYUIOPLKJHGFDSAZXCVBNMlkjhgfdsaqwertpoiuyzxcvbnm1098723456";
$randomString = substr(str_shuffle($character),0,$length);
$this->randomCharacter = $randomString;
if ($this->validate()){
$this->image->saveAs($path .$this->randomCharacter .'.'.$this->image->extension);
//$this->image->saveAs(\Yii::getAlias("#backend/web/uploads/{$randomString}.{$this->image->extension}"));
return true;
}else{
return false;
}
}
}

public function actionCreate()
{
$addd_at = time();
$model = new Product();
$upload = new UploadForm();
if($model->load(Yii::$app->request->post())){
//get instance of the uploaded file
$model->image = UploadedFile::getInstance($model, 'image');
$upload->upload();
$model->added_at = $addd_at;
$model->image = 'uploads/' .$upload->randomCharacter .'.'.$model->image->extension;
$model->save();
return $this->redirect(['view', 'product_id' => $model->product_id]);
} else{
return $this->render('create', [
'model' => $model,
]);
}
}

Answer 1

Does it throw any errors?
This is propably permission issue. Try changing the "uploads" directory permission to 777 (for test only).

You load your Product ($model) with form data.
if($model->load(Yii::$app->request->post()))
But Uploadform ($upload) never gets filled in your script. Consequently, $upload->image will be empty.
Since you declare 'skipOnEmpty' => false in the file validator of the UploadForm rules, the validation on $upload will fail.
That is why your if statement in the comments above (if($upload->upload()) doesn't save $model data.
I don't see why you would need another model to serve this purpose. It only complicates things, so I assume its because you copied it from a tutorial. To fix and make things more simple, just do the following things:
Add property to Product model
public $image;
Add image rule to Product model
[['image'], 'file', 'skipOnEmpty' => false, 'extensions'=> 'png, jpg,jpeg'],
Adjust controller create action
public function actionCreate()
{
$model = new Product();
if($model->load(Yii::$app->request->post()) && $model->validate()) {
// load image
$image = UploadedFile::getInstance($model, 'image');
// generate random filename
$rand = Yii::$app->security->generateRandomString(10);
// define upload path
$path = 'uploads/' . $rand . '.' . $image->extension;
// store image to server
$image->saveAs('#webroot/' . $path);
$model->added_at = time();
$model->image = $path;
if($model->save()) {
return $this->redirect(['view', 'product_id' => $model->product_id]);
}
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
Something like this should do the trick.

Your UploadForm class is already on Backend so on function upload of UploadForm Class it should be like this:
Change this line:
$path = \Yii::getAlias("#backend/web/uploads/");
to this:
$path = \Yii::getAlias("uploads")."/";
