Question

我想删除图片并在更新视图（yii）重新显示上传的字段。

有一张图片已上传。
当用户删除此图像时。
此时图片将被删除，上传$form->filefield将显示在图片位置。

这是视图

<div id="forAjaxRefresh"><img src="<?php echo $file; ?>" width="150px" /></div>

<?php echo CHtml::ajaxLink('clickMe', array('ajax'), array('update'=>'#forAjaxRefresh'));?>

这是控制器

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';
    }

当我尝试的时候。它正在显示'OK'。但我想在上面显示上传文件字段。我该怎么办？请帮帮我。

请帮帮我!!!

尽管勺子喂养某人并不健康，但看起来你有很多麻烦。看到它非常简单，你采用了复杂的方法。

按照步骤操作即可。

View

 <?php echo $form->labelEx($model,'full_version'); ?>                
 <?php if($model->full_version == '')
           echo $form->filefield($model,'full_version',array('style'=>'width:100%;')); 
       else
       {
           echo '<div id="file"><b>'.$model->full_version.'</b> '.CHtml::AjaxLink('Delete',CController::createUrl('removeFinalVersion',array('id'=>$model->id)),array('update'=>'#file')).'</div>';
       }?>
<?php echo $form->error($model,'full_version'); ?>

现在我们要做的是用文件上传think替换file Div。如果您必须上传比文件字段更多的字段，那么您可以使用单独的文件并在控制器和回显中呈现它。但是对于这个演示，我只考虑只返回一个项目。

所以当Ajax请求发生时，事情会转到actionRemoveFinalVersion，其中所有的谈话都需要完成并且必须返回filefield

它看起来像这样

public function actionRemoveFinalVersion($id)
    {
            $user = Products::model()->findByPk($id);
            if($user === null)
                yii::app()->end();
            $user->full_version = '';
            $user->save();
            //return CHtml::activeFileField($model,'full_version',array('style'=>'width:100%;'));
            echo CHtml::Tag('input',
                    array(
                        'style'=>"width:100%;",
                        'name'=>"Products[full_version]" ,
                        'id'=>"Products_full_version",
                        'type'=>"file"));
    }

专注于返回的name的{{1}}和id。它需要精确，以便filefield可以发生。 validation。如果你做的更正，你也应该这样做。

另外，在使用AJAX时，请在Firefox中使用Firebug工具，在Chrome中使用类似工具

            $model->active = 1;
