我的模特（fadepreciation.php）

public function afterSave( ) {
        $this->addImages( );
        parent::afterSave( );
    }

    public function addImages( ) {
        //If we have pending images
        if( Yii::app( )->user->hasState( 'images' ) ) {
            $userImages = Yii::app( )->user->getState( 'images' );
            //Resolve the final path for our images
            $path = Yii::app( )->getBasePath( )."/../images/uploads/{$this->id}/";
            //Create the folder and give permissions if it doesnt exists
            if( !is_dir( $path ) ) {
                mkdir( $path );
                chmod( $path, 0777 );
            }

            //Now lets create the corresponding models and move the files
            foreach( $userImages as $image ) {
                if( is_file( $image["path"] ) ) {
                    if( rename( $image["path"], $path.$image["filename"] ) ) {
                        chmod( $path.$image["filename"], 0777 );
                        $img = new Image( );
                        $img->size = $image["size"];
                        $img->mime = $image["mime"];
                        $img->name = $image["name"];
                        $img->source = "/images/uploads/{$this->id}/".$image["filename"];
                        $img->somemodel_id = $this->id;
                        if( !$img->save( ) ) {
                            //Its always good to log something
                            Yii::log( "Could not save Image:\n".CVarDumper::dumpAsString( 
                                $img->getErrors( ) ), CLogger::LEVEL_ERROR );
                            //this exception will rollback the transaction
                            throw new Exception( 'Could not save Image');
                        }
                    }
                } else {
                    //You can also throw an execption here to rollback the transaction
                    Yii::log( $image["path"]." is not a file", CLogger::LEVEL_WARNING );
                }
            }
            //Clear the user's session
            Yii::app( )->user->setState( 'images', null );
        }
    }

我的观点（_form.php）

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'fa-depreciation-form',
    'enableAjaxValidation'=>false,
    'htmlOptions' => array('enctype' => 'multipart/form-data'),
)); ?>

    <p class="note">Fields with <span class="required">*</span> are required.</p>

    <?php echo $form->errorSummary($model); ?>
<!-- Other Fields... -->
        <div class="row">
            <?php echo $form->labelEx($model,'photos'); ?>
            <?php
            $this->widget( 'xupload.XUpload', array(
                'url' => Yii::app( )->createUrl( "/fadepreciation/upload"),
                //our XUploadForm
                'model' => $photos,
                //We set this for the widget to be able to target our own form
                'htmlOptions' => array('id'=>'fa-depreciation-form'),
                'attribute' => 'file',
                'multiple' => true,
                //Note that we are using a custom view for our widget
                //Thats becase the default widget includes the 'form' 
                //which we don't want here
                //'formView' => 'application.views.faDepreciation._form',
                )    
            );
            ?>
        </div>
    <div class="row buttons">
        <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>
    </div>

<?php $this->endWidget(); ?>

</div><!-- form -->

我的控制器（fadepreciation.php）

public function actionCreate()
    {
        $model=new FaDepreciation;
        Yii::import( "xupload.models.XUploadForm" );
        $photos = new XUploadForm;
        // Uncomment the following line if AJAX validation is needed
        // $this->performAjaxValidation($model);

        if(isset($_POST['FaDepreciation']))
        {
            //Assign our safe attributes
            $model->attributes=$_POST['FaDepreciation'];
            //Start a transaction in case something goes wrong
            $transaction = Yii::app( )->db->beginTransaction( );
            try {
                //Save the model to the database
                if($model->save()){
                    $transaction->commit();
                    $this->redirect(array('view','id'=>$model->id));
                }
            } catch(Exception $e) {
                $transaction->rollback( );
                Yii::app( )->handleException( $e );
            }
            if($model->save())
                $this->redirect(array('view','id'=>$model->id));
        }

        Yii::import( "xupload.models.XUploadForm" );
        $photos = new XUploadForm;
        $this->render('create',array(
            'model'=>$model,
            'photos'=>$photos,
        ));

    }
public function actionUpload( ) // From xupload nothing change

Answer 1

您需要做的是创建自定义表单。从xupload _form复制内容并粘贴它，删除开始表单 - 结束表单。添加到您的小部件'formView'自定义表单中的引用。

Answer 2

提交表单有什么问题？

是的，可以完成文件限制。请确保您遵循这些http://www.yiiframework.com/wiki/348/xupload-workflow/

Answer 3

Q1：form submition无法正常工作，因为XUpload小部件会生成自己的表单标记。所以你生成的HTML有一个以另一种形式嵌入的表单，你应该使用widget的formView选项指向没有表单标签的视图，如xupload workflow wiki

中所述

Q2：您应该在小部件配置中使用maxNumberOfFiles选项

这一切应该是这样的：

 <?php
            $this->widget( 'xupload.XUpload', array(
                'url' => Yii::app( )->createUrl( "/fadepreciation/upload"),
                //our XUploadForm
                'model' => $photos,
                //We set this for the widget to be able to target our own form
                'htmlOptions' => array('id'=>'fa-depreciation-form'),
                'attribute' => 'file',
                'multiple' => true,
                //Note that we are using a custom view for our widget
                //Thats becase the default widget includes the 'form' 
                //which we don't want here
                'formView' => 'application.views.faDepreciation._form',
                'options' => array('maxNumberOfFiles' => 5)
                )    
            );
            ?>

Answer 4

只需使用'showForm'参数如下：

<?php
$this->widget( 'xupload.XUpload', array(
  ...
  'showForm' => false,
  ...
));
?>

也许，此选项已在xupload的下一版本中添加。

Answer 5

我知道这是一个古老的帖子，但也许这个答案可以帮助某人解决这个问题。

我发现它是由文件/xupload/views/form.php中的最后一行引起的（默认设置）。看起来if语句在某种程度上与...相反......在挖掘中，为了虚假值，它会渲染代码。例如：

<?php 
echo $this->showForm; 
if($this->showForm) echo CHtml::endForm(); 
echo $this->showForm; 
?>

返回： weirg output

也许我错过了一些东西，但它看起来很奇怪......不是吗？
