yii2：爲什麼$模型 - >圖像後FileUploadUI

Question

這個上傳圖片空是我的_form.php這個：

<?php 


    use dosamigos\fileupload\FileUploadUI; 


// with UI 

    ?> 
    <?= 

    FileUploadUI::widget([ 
     'model' => $model, 
     'attribute' => 'image', 
     'url' => ['media/upload', 'id' => 'image'], 
     'gallery' => false, 
     'fieldOptions' => [ 
      'accept' => 'image/*' 
     ], 
     'clientOptions' => [ 
      'maxFileSize' => 200000 
     ], 
     // ... 
     'clientEvents' => [ 
      'fileuploaddone' => 'function(e, data) { 
           console.log(e); 
           console.log(data); 
          }', 
      'fileuploadfail' => 'function(e, data) { 
           console.log(e); 
           console.log(data); 
          }', 
     ], 
    ]); 

    ?> 

我的文件在我的主機上傳，但我需要的是URL

這是我的產品控制器和形象爲空：

public function actionCreate() 
     { 
     $request = Yii::$app->request; 
     $model = new Product(); 
     $idCon = Yii::$app->user->id; 

     $model->user_id = $idCon; 
     if ($request->isAjax) 
      { 
      /* 
      * Process for ajax request 
      */ 
      Yii::$app->response->format = Response::FORMAT_JSON; 

      if ($request->isGet) 
       { 
       return [ 
        'title' => "Create new Product", 
        'content' => $this->renderAjax('create', [ 
         'model' => $model, 
        ]), 
        'footer' => Html::button('Close', ['class' => 'btn btn-default pull-left', 'data-dismiss' => "modal"]) . 
        Html::button('Save', ['class' => 'btn btn-primary', 'type' => "submit"]) 
       ]; 
       } 
      else if ($model->load($request->post()) && $model->save()) 
       { 

       return [ 
        'forceReload' => '#crud-datatable-pjax', 
        'title' => "Create new Product", 
        'content' => '<span class="text-success">Create Product success</span>', 
        'footer' => Html::button('Close', ['class' => 'btn btn-default pull-left', 'data-dismiss' => "modal"]) . 
        Html::a('Create More', ['create'], ['class' => 'btn btn-primary', 'role' => 'modal-remote']) 
       ]; 
       } 
      else 
       { 
       return [ 
        'title' => "Create new Product", 
        'content' => $this->renderAjax('create', [ 
         'model' => $model, 
        ]), 
        'footer' => Html::button('Close', ['class' => 'btn btn-default pull-left', 'data-dismiss' => "modal"]) . 
        Html::button('Save', ['class' => 'btn btn-primary', 'type' => "submit"]) 
       ]; 
       } 
      } 
     else 
      { 
      /* 
      * Process for non-ajax request 
      */ 
      if ($model->load($request->post()) && $model->save()) 
       { 


       return $this->redirect(['view', 'id' => $model->id]); 
       } 
      else 
       { 
       return $this->render('create', [ 
          'model' => $model, 
       ]); 
       } 
      } 

     } 

，這是我的模型：

use Yii; 
use yii\web\UploadedFile; 
use yii\base\Model; 


/** 
* This is the model class for table "product". 
* 
* @property integer $id 
* @property string $name 
* @property string $price 
* @property string $image 
* @property string $url 
* @property integer $user_id 
* 
* @property ConProduct[] $conProducts 
* @property User $user 
* @property Sales[] $sales 
*/ 
class Product extends \yii\db\ActiveRecord 
    { 


    /** 
    * @inheritdoc 
    */ 
    public static function tableName() 
     { 
     return 'product'; 

     } 


    /** 
    * @inheritdoc 
    */ 
    public function rules() 
     { 
     return [ 
       [['price'], 'number'], 
       [['user_id'], 'integer'], 
       [['name', 'image'], 'string', 'max' => 300], 
       [['url'], 'string', 'max' => 255], 
       [['user_id'], 'exist', 'skipOnError' => true, 'targetClass' => User::className(), 'targetAttribute' => ['user_id' => 'id']], 
     ]; 

     } 

我怎樣才能獲得圖像URL與$模型 - >圖像在控制器！？

您是否嘗試過使用yii\web\UploadedFile::getInstance()？

$model->image = UploadedFile::getInstance($model, 'image'); 
if ($model->upload()) { 
    // do some stuff with file 
}
