Question

以下是我用于视频和图像上传的代码。图片预览显示为选择，但是当我选择要上传的视频时，它将上传但不显示任何预览。

任何建议，如果我缺少一些东西。

$form->field($model, 'sessionvideos')->widget(FileInput::classname(), [
        'options' => ['accept' => 'pdf', 'mp3', 'mp4', 'multiple' => true],
        'pluginOptions' => [
            'previewFileType' => 'any',
            'validateInitialCount' => true,
            'initialPreviewAsData' => true,
            'allowedFileExtensions' => ['pdf', 'mp3', 'mp4'],
            'maxFileCount' => 18,
            'showUpload' => false,
    ]]);
