File is an input element that represents a list of file items, each consisting of a file name, a file type, and a file body (the contents of the file).
<?php
declare(strict_types=1);
namespace App\Form;
use Yii\Extension\Model\FormModel;
final class TestForm extends FormModel
{
private array $attachFiles = [];
}
Widget view:
<?php
declare(strict_types=1);
use Yii\Extension\\Form\File;
use Yii\Extension\\Form\Form;
use Yii\Extension\Form\SubmitButton;
use Yii\Extension\Model\Contract\FormModelContract;
/**
* @var FormModelContract $data
* @var object $csrf
*/
?>
<?= Form::widget()->action('widgets')->csrf($csrf)->begin() ?>
<?= File::widget()->for($data, 'attachFiles') ?>
<hr class="mt-3">
<?= SubmitButton::widget()->class('button is-block is-info is-fullwidth')->value('Save') ?>
<?= Form::end() ?>
That would generate the following code:
<form action="widgets" method="POST" _csrf="WmTTWFg8aEFC-PZf9n_JrjxF4Tgy-frRERntvNNA3iAqC79ua28-FwSXpSnGGqv8TzeiU3qmlodbU4zrly2VSg==">
<input type="hidden" name="_csrf" value="WmTTWFg8aEFC-PZf9n_JrjxF4Tgy-frRERntvNNA3iAqC79ua28-FwSXpSnGGqv8TzeiU3qmlodbU4zrly2VSg==">
<input type="file" id="testform-attachfiles" name="TestForm[attachFiles][]">
<hr class="mt-3">
<div>
<input type="submit" id="submit-64649334142001" class="button is-block is-info is-fullwidth" name="submit-64649334142001" value="Save">
</div>
</form>
