Yii2 no file when loading image?

Question

Yii

Hello.
Generated via CRUD forms. You need to upload images. In the database field 'VARCHAR'. advanced template.
In the 'Team' model I add:

use yii\base\models;
use yii\web\UploadedFile;
...........................................
[['photo_team'], 'file'],

In backend/views/team/_form.php

<?= $form->field($model, 'photo_team')->fileInput() ?>

But absolutely nothing happens. No error, no file selection field. I remove everything from backend/views/team/_form.php - the form is as it was - it is.
The view also has one more -

<?= $form->field($model, 'party')->dropDownList([ 'A' => 'A', 'B' => 'B', 'C' => 'C', 'D' => 'D', 'E' => 'E', 'F' => 'F', ], ['prompt' => '']) ?>

but there is no list in frontend.
CRUD did this
What am I doing wrong?
Thanks in advance.

Answer 1

1. To develop on yii2, you need to enable the debug panel to see errors.
2. Most likely a problem with form validation.
3. Give the full codes, models, views with the form and the controller that processes it.
4.

I remove everything from backend/views/team/_form.php - the form is as it was - it is.

- whatoooo is that? Write more in Russian. What does "the form as it was - so it is" mean? Where there is? In the browser in code?

I'm cleaning everything

- What is this?

Answer 2

If you clear the backend/views/team/_form.php file and there are no changes on the page, then you are working with the wrong file

Answer 3

Try using kartik widgets.
on my page like this:

echo \kartik\widgets\FileInput::widget([
    'name' => 'attachment',
    'pluginOptions' => [
        'showPreview' => false,
        'showCaption' => true,
        'showRemove' => true,
        'showUpload' => true,
        'uploadUrl' => \yii\helpers\Url::to(['/report/report-upload'])
    ]
]);

Everything works fine. Only then I had to increase the maximum size of the uploaded file, but it already seemed to be in the PHP settings.
