            $path = Yii::app( )->getBasePath( )."/../images/uploads/{$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

My view (_form.php)

My controller (fadepreciation.php)

public function actionUpload( ) // From xupload nothing change

回答1:

What you need to do is to create a custom form. Copy the content from xupload _form and paste it removing the begin form - end form. Add to your widget 'formView' the reference at the custom form.

回答2:

what is the issue about submission form?

yes file limit can be done. Please make sure you follow these http://www.yiiframework.com/wiki/348/xupload-workflow/

Q1: form submition is not working, because the XUpload widget generates its own form tag. so your generated HTML has a form embebed in another form, you should use formView option of the widget to point to a view that has no form tags, as described in the xupload workflow wiki

Q2: You should use maxNumberOfFiles option in the widget config

It all should look like this:

 <?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)
                )    
            );
            ?>

回答4:

Just use 'showForm' parameter as follow:

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

Maybe, this option been added in next versions of xupload.

回答5:

I know that it's an old post but maybe this answer will help someone to solve this issue.

I found out that it's caused by the last line in the file /xupload/views/form.php (with default settings). It looks like the if statement is somehow working opposite... in mining that for false value it's rendering the code. For example:

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

returns:

Maybe I'm missing something but it looks weird... isn't it?
