无法读取输入的文件yii2的名称

Question

当我调用控制器中输入的文件名时，使用var_dump查看结果我有此错误：enter image description here

这是视图：

<div class="custom-file">
                                            <input type="file" name="image" class="custom-file-input" id="inputGroupFile01" >
                                            <label class="custom-file-label" for="inputGroupFile01"><?= Yii::t('app', 'Choose file(s)...') ?></label>
                                        </div>

这是控制器：

 exit(var_dump(UploadedFile::getInstanceByName( 'image')));

我也尝试这样做：

exit(var_dump($_FILES["image"]));

但是结果是：enter image description here

我在项目的这一部分不使用模型

@ ttrasn这是表格：
