我想刪除一張圖片並在更新視圖（yii）中重新顯示上傳的字段。通過AJAX刪除並顯示FileField
- 有其上載的圖像。
- 當用戶刪除這個圖像。
- 當時的圖像將刪除並上傳
$form->filefield將出現在圖像的地方。
這是視圖
<div id="forAjaxRefresh"><img src="<?php echo $file; ?>" width="150px" /></div>
<?php echo CHtml::ajaxLink('clickMe', array('ajax'), array('update'=>'#forAjaxRefresh'));?>
這是控制器
public function actionAjax()
{
$model=new CompanyLicense('search');
//$this->render('update', array('model'=>$model,'test'=>'test'), false, true);
//echo "$form->labelEx($model,'file_path');
//$form->fileField($model,'file_path', array('class'=>'input-file'));
//$form->error($model,'file_path'); ";
//echo "$form->labelEx($model,'file_path')";
echo 'OK';
}
當我試圖喜歡它。它在顯示'OK'。但我想顯示上傳文件字段。我怎麼辦？請幫幫我。

最新的MVC
模型沒有什麼變化
控制器
public function actionAjax($id)
{
$model=new CompanyLicense();
//$this->render('uploadfield', array());
//echo "$form->labelEx($model,'file_path');
//$form->fileField($model,'file_path', array('class'=>'input-file'));
//$form->error($model,'file_path'); ";
//echo "$form->labelEx($model,'file_path')";
echo $this->renderPartial('uploadfield',array('model'=>$model),false,true);
/*
$model=Company::model()->findByPk($_GET['id']);
if($model){
$file = '/images/'. $model->id . '/'. $model->file_path;
unlink(dirname(__FILE__) . '/../../..'.$file);
}
<br />
*/
}

請幫幫我！
是你能夠使其工作？ – 2012-07-24 20:40:21
是的，我的最後一個ans可以做到，我把你的echo CHtml :: Tag換成我的控制器。兩種解決方案都工作正常。 – 2012-07-25 05:04:00
