How to display an image in Yii2 and specify a list of allowed extensions?

Question

Yii

There is a form several several text fields.
The last field is for files. In the controller, this code => the picture is saved in the desired directory. and enters the img table field with the string type = zalman-z7-neo.200x200n.jpg
<?= $form->field($model, 'img')->fileInput()?>

if (Yii::$app->request->isPost) {
            $model->load(Yii::$app->request->post());
            $model->img = UploadedFile::getInstance($model, 'img');
            $model->img->saveAs("img/category/computers/{$model->img->baseName}.{$model->img->extension}") ;

I'm trying to get her out.

<?php if($computer->img): ?>
                            <p>test</p>
                                <img src="/web/img/category/computers/<?= $computer->img?>" alt="" width="200" height="200">
                            <?php endif; ?>

if works for me, test is displayed, but the picture does not show.


in debug it shows like this. i.e. the path is set.

<img src="/web/img/category/computers/zalman-z7-neo.200x200n.webp" alt="" width="200" height="200">

and how to specify extensions, not rules (it didn’t work out in them), but in some other way, for example, pass it to the fileInput value (HERE for example) if this is possible

Answer 1

Decided to change the path.

<img src="/img/category/computers/zalman-z7-neo.200x200n.webp" alt="" width="200" height="200">

and specifying $model->img->saveAs after the validation check.
