Why is there an error when uploading two pictures?

Question

Yii

I tried to organize the loading of two pictures from two fields figuratively like this

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

    <?= $form->field($model, 'logo')->fileInput([ 'accept' => 'image/*']) ?>
    
    <?= $form->field($model, 'footer')->fileInput([ 'accept' => 'image/*']) ?>

    <button>Submit</button>

<?php ActiveForm::end() ?>

// controller
<?php
$model->logo = UploadedFile::getInstance($model, 'logo');
$model->footer = UploadedFile::getInstance($model, 'footer');
if ($model->logo && $model->validate()) {
                $model->logo->saveAs(Yii::getAlias('@frontend/web/').'/foto/' . $model->logo->baseName . '.' . $model->logo->extension);}
            if($model->footer && $model->validate()){
                $model->footer->saveAs(Yii::getAlias('@frontend/web/').'/foto/' . $model->footer->baseName . '.' . $model->footer->extension);}

$model->save();
The database is saved in a folder no, why don't you tell me?

Answer 2

Perhaps there are no rights or the path is wrong.
