cakePHP 3.0 uploading images

Question

I want to upload images in my cakephp 3.0 app. But I get the error message:

Notice (8): Undefined index: Images [APP/Controller/ImagesController.php, line 55

In your view file, add like this, in my case Users/dashboard.ctp

Form->create($particularRecord, ['enctype' => 'multipart/form-data']);
echo $this->Form->input('upload', ['type' => 'file']);
echo $this->Form->button('Update Details', ['class' => 'btn btn-lg btn-success1 btn-block padding-t-b-15']);
echo $this->Form->end();       
?>

In your controller add like this, In my case UsersController

if (!empty($this->request->data)) {
if (!empty($this->request->data['upload']['name'])) {
$file = $this->request->data['upload']; //put the data into a var for easy use

$ext = substr(strtolower(strrchr($file['name'], '.')), 1); //get the extension
$arr_ext = array('jpg', 'jpeg', 'gif'); //set allowed extensions
$setNewFileName = time() . "_" . rand(000000, 999999);

//only process if the extension is valid
if (in_array($ext, $arr_ext)) {
    //do the actual uploading of the file. First arg is the tmp name, second arg is 
    //where we are putting it
    move_uploaded_file($file['tmp_name'], WWW_ROOT . '/upload/avatar/' . $setNewFileName . '.' . $ext);

    //prepare the filename for database entry 
    $imageFileName = $setNewFileName . '.' . $ext;
    }
}

$getFormvalue = $this->Users->patchEntity($particularRecord, $this->request->data);

if (!empty($this->request->data['upload']['name'])) {
            $getFormvalue->avatar = $imageFileName;
}


if ($this->Users->save($getFormvalue)) {
   $this->Flash->success('Your profile has been sucessfully updated.');
   return $this->redirect(['controller' => 'Users', 'action' => 'dashboard']);
   } else {
   $this->Flash->error('Records not be saved. Please, try again.');
   }
}

Before using this, create a folder in webroot named upload/avatar.

Note: The input('Name Here'), is used in

$this->request->data['upload']['name']

you can print it if you want to see the array result.

Its works like a charm in CakePHP 3.x
