How to display an image?

Question

MySQL

Guys I can not understand anything.
I'm doing tests with loading pictures on Yii2.

Контроллер

<?php

namespace backend\controllers;
use backend\models\UploadedForm;

class CourseController extends SrcController
{
    public function actionUpload()
    {
        $model = new UploadedForm();

        if (Yii::$app->request->isPost) {
            var_dump ($model); die;
            $model->image = UploadedFile::getInstances($model, 'image');
            
            if ($model->upload()) {
                // file is uploaded successfully
                return;
            }
        }

        return $this->render('upload', ['model' => $model]);
    }
}

Модель

<?php
namespace backend\models;

use yii\base\Model;
use yii\web\UploadedFile;

class UploadedForm extends Model
{
    /**
     * @var UploadedFile
     */
    public $image;

    public function rules()
    {
        return [
            [['image'], 'file', 'skipOnEmpty' => false],
        ];
    }
    
    public function upload()
    {
        if ($this->validate()) {
            var_dump ($this->image); die;
            $this->image->saveAs('uploads/' . $this->image->baseName . '.' . $this->image->extension);
            return true;
        } else {
            return false;
        }
    }
}

Форма
<?php
use yii\helpers\Html;
use yii\helpers\Url;
use yii\widgets\ActiveForm;

<?php $form = ActiveForm::begin() ?>
    <?= $form->field($model, 'image')->fileInput() ?>
    <button>Submit</button>
<?php ActiveForm::end() ?>

In the controller I do:
var_dump ($model); die;
I get:

object(backend\models\UploadedForm)#60 (6) { ["image"]=> NULL ["_errors":"yii\base\Model":private]=> NULL ["_validators":"yii\base\Model":private]=> NULL ["_scenario":"yii\base\Model":private]=> string(7) "default" ["_events":"yii\base\Component":private]=> array(0) { } ["_behaviors":"yii\base\Component":private]=> NULL }

Here is the debug.

Variable $_FILES = NULL
Where am I so dumb that I don't see the end-to-end error?

Collect statistics in a separate table, for example every day, and do the usual select.
