我制作了一个自定义模型，它是一个Upload Formwhich extends Model。我根据 yii2 的文档制作了一份副本，UploadedFile但到目前为止，正在工作的是上传的文件，当它保存在web/uploads. 我创建了一个名为$storeList. 我期待在我调用$model->load((Yii::$app->request->post())表单内的值之后将分配给$model->storeList但变量只是空的。有人可以告诉我我在哪里做错了吗？

结构是这样的。index.php首先加载，它包括select_package.php哪个具有呈现upload.php.

索引.php：

<div id="uploadStatusFrame" class="uploadStatusFrame">
    <?php
        include('layouts/select_package.php');
    ?>
</div>

<button id="uploadButton" class="btn btn-success" 
                style='position:relative; left:10px; top: -44px'>Upload to Server</button>

<script>
$('#uploadButton').click(function(){
    $("#submitButton").trigger("click");
});
</script>

选择包.php：

<?= 
    Tabs::widget([
        'id' => 'dashboardTab',
        'options' => ['id' => 'mainTab',
                    'class' => 'nav nav-tabs',
                        'style' => 'font-size: 14px; font-weight: bold;border-bottom: none;',
                    ],
        'items' => [
        [
            'label' => 'New Firmware',
            'active' => true,
                'style' => 'font-size: 14px; font-weight: bold',
            'options' => ['id' => 'tab1',
                        'class' => 'nav nav-tabs',
                        'style' => 'width:1044px;margin:1px;background:#428bca; 
                        height:453px;border:2px solid #428bca;'
                        ],
            'content' => $this->render('/upload-package/upload', [
                            'model' => $model,
                        ]),
        ],
    ]);
?>

上传包控制器.php：

class UploadPackageController extends Controller
{
    public $layout = "default";

    public function behaviors()
    {
        return [
            'verbs' => [
                'class' => VerbFilter::className(),
                'actions' => [
                    'delete' => ['post'],
                ],
            ],
        ];
    }

    /**
     * Lists all SystemConfig models.
     * @return mixed
     */
    public function actionIndex()
    {
        $model = new UploadForm;

        if ($model->load(Yii::$app->request->post())) {
            $model->imageFile = UploadedFile::getInstance($model, 'imageFile');
            $model->storeList = UploadedFile::getInstance($model, 'storeList');     // **<<-- How should I handle this?**

            if ($model->upload()){
                return $this->render('index', [
                    'model' => $model,
                    'storeList' => $model->storeList,
                ]);
            }
        }

        return $this->render('index', [
            'model' => $model,
            'storeList' => 'NONE',
        ]);
    }
}

上传表单.php：

class UploadForm extends Model
{
    /**
     * @var UploadedFile
     */
    public $imageFile;
    public $storeList;

    public function rules()
    {
        return [

        ];
    }

    public function upload()
    {
        if ($this->validate()) {
            $this->imageFile->saveAs('uploads/' . $this->imageFile->baseName . '.' . $this->imageFile->extension);
            return true;
        } else {
            return false;
        }
    }
}

上传.php

    <?= $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data',
            'id' => 'fileSenderForm', 
            'name' => 'fileSenderForm', 
        ]]) ?>

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

    <?= $form->field($model, 'storeList')->textInput(['value' => 'ANY_VALUE_HERE'])->label(); ?>

    <?= Html::submitButton('Submit', ['id' => 'submitButton']); ?>

    <?php ActiveForm::end() ?>

您的问题及其原因

如果您检查请求的内容，您将看到您的值已发送但未分配到模型中。原因是 Yii2 的安全特性。load()- 方法所做的称为模型属性的大规模分配。由于这可能存在潜在危险，Yii 要求所有被大量分配的属性

  • 已验证
  • 或声明为“安全”（实际上也是验证器）

解决方案

所以......您需要将要大量分配的属性添加$model->load(Yii::$app->request->post())到验证器。否则它们将被跳过。还要删除UploadedFile::getInstance这个字段，因为这个属性显然不是关于文件的。

您可以使用实际的验证器，也可以将它们声明为安全的。您的规则方法可能如下所示：

public function rules() {
    return [
        [['storeList'], 'string', 'max'=>64],
    ];
}

或者如果您不想指定任何“真实”验证器，只需将属性声明为安全：

public function rules() {
    return [
        [['storeList'], 'safe'],
    ];
}
