Question

这是我的视图文件，它有一个表格应该发布文本变量数据为0000000005的文件。但由于某种原因，控制器内的加载功能不会填充这些数据。

<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;

/* @var $this yii\web\View */
/* @var $model backend\models\customs\UploadForm */
/* @var $form ActiveForm */
?>

<div class="vendor_file_upload_form">

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

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

        <?= $form->field($model,'apid')->textInput(); ?>

        <div class="form-group">
            <?= Html::submitButton(Yii::t('app', 'Submit'), ['class' => 'btn btn-primary']) ?>
        </div>

    <?php ActiveForm::end(); ?>

</div><!-- vendor_file_upload_form -->

这是我的控制器

public function actionFiles($id=null)
{
    $model = new UploadForm();

    if ($model->load(Yii::$app->request->post()))
    {
        $model->AppFile = UploadedFile::getInstance($model, 'AppFile');

        if ($model->upload())
        {
            \Yii::$app->getSession()->setFlash('success', 'File has been successfully uploaded.');
            return $this->redirect(['index']);
        }
        else
        {
            \Yii::$app->getSession()->setFlash('error', 'Wrong File Format , Try proper format.');
            return $this->redirect(['index']);
        }
    }
}

我发现由于某种原因，加载数据不会加载所有已发布的表单参数。我花了3个小时，我仍然无法理解为什么我的表单数据没有正确传输。

我检查了Payload，我发现以下内容意味着我的数据正常，但加载功能无法正常加载。

------ WebKitFormBoundaryZfszVA0IZuj02ZFT Content-Disposition：form-data; NAME = “_ CSRF-后端”

编辑：下面是我的模型文件，

<?php
/**

 * Date: 1/8/2017
 * Time: 9:52 PM
 */

namespace backend\models\customs;

use backend\models\ApplicationFiles;
use yii\base\Model;
use yii\web\UploadedFile;

/**
 * UploadForm is the model behind the upload form.
 */
class UploadForm extends Model
{
    /**
     * @var UploadedFile
     */
    public $AppFile; //files which needs to be uploaded
    public $apid; //application_id

    /**
     * @return array the validation rules.
     */
    public function rules()
    {
        return [
            [['apid'], 'required','message'=>'No Application Id found'],
            [['AppFile'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg'],

        ];
    }


    public function upload()
    {
        //upload on the backed/uploads folder with time stamp as the file name
        if ($this->validate()) {

            $File_name = time() . '.' . $this->AppFile->extension;

            if($this->AppFile->saveAs(\Yii::$app->basePath.'/uploads/' .$File_name ))
            {
                $model = new ApplicationFiles();
                $model->name = $File_name;
                $model->path = \Yii::$app->basePath.'/uploads/' .$File_name;
                $model->application_id = $this->apid;
               // $model->type =
                $model->save();
            }

            return true;
        }
        else
        {
            return false;
        }
    }
}
?>

控制器中的yii2负载模型不会加载表单的发布数据
