Yii framework CMultifileupload not working - yii

Question

I'm trying to implement a multiple file upload using CMultiFileUpload with CUploadedFile, but it doesn't work. Specifically, _POST is not working even considering that I'm using 'enctype' => 'multipart/form-data' in the options in the view:
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'examen-form',
'enableAjaxValidation'=>false,
'htmlOptions' => array('enctype' => 'multipart/form-data'),
)); ?>
and this is the widget and parameters used for CMultiFileUpload:
<div class="row">
<?php echo $form->labelEx($model,'archivo_foto')?>
<?php //echo CHtml::activeFileField($model,'archivo_foto')?>
<?php $this->widget('CMultiFileUpload', array(
'model' => $model,
'name' => 'archivo_foto',
'accept' => 'jpeg|jpg|gif|png|txt', // useful for verifying files
'duplicate' => 'Duplicate file!', // useful, i think
'denied' => 'Invalid file type', // useful, i think
'max' => 10,
'htmlOptions' => array( 'multiple' => 'multiple', 'size' => 25 ),
)); ?>
<?php echo $form->error($model,'archivo_foto')?>
</div>
On the other hand, the controller action is implemented this way:
public function actionUpdateam($id)
{
$model=$this->loadModel($id);
$dir=Yii::getPathOfAlias('application.uploads');
$model->archivo_documento='funciona 0';
if(isset($_POST['Examen'])) {
$model->attributes=$_POST['Examen'];
// THIS is how you capture those uploaded images: remember that in your CMultiFile widget, you set 'name' => 'archivo_foto'
$images = CUploadedFile::getInstancesByName('archivo_foto');
// proceed if the images have been set
$model->archivo_documento='funciona uno';
if (isset($images) && count($images) > 0) {
$model->archivo_documento='funciona dos';
// go through each uploaded image
foreach ($images as $image) {
echo $image->name.'<br />';
$image->saveAs($dir.'/'.$image->name);
$model->archivo_foto = $model->archivo_foto."+".$image->name;
}
// save the rest of your information from the form
if ($model->save()) {
$this->redirect(array('view','id'=>$model->id));
}
}
}
$this->render('update_am',array(
'model'=>$model,
));
}
And at last, I think that is important to mention the rule used for the model (it might be the cause of the problem as well):
array('archivo_foto','file','allowEmpty'=>true,'maxFiles'=>10),
I think that the problem is in post method, because the controller is not uploading the files and is not making any changes in the database. But I'm not sure.

Answer 1

Try changing to 'htmlOptions'=>array('multiple'=>true).

Answer 2

Add following code in the Form
'htmlOptions' => array(
'enctype' => 'multipart/form-data',
),
Like
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'form',
// Please note: When you enable ajax validation, make sure the corresponding
// controller action is handling ajax validation correctly.
// There is a call to performAjaxValidation() commented in generated controller code.
// See class documentation of CActiveForm for details on this.
'enableAjaxValidation'=>true,
'htmlOptions' => array(
'enctype' => 'multipart/form-data',
),
)); ?>

Answer 3

I am using the same extension and it is wokring for me with these codes
In the view file
<?php $form = $this->beginWidget('CActiveForm', array(
'id'=>'adpost-form',
'enableClientValidation'=>true,
'clientOptions' => array(
'validateOnSubmit'=>true,
'validateOnChange'=>false,
'afterValidate'=>'js:submiAjaxForm'
),
'htmlOptions' => array('enctype' => 'multipart/form-data'),
)); ?>
<?php
$this->widget('CMultiFileUpload', array(
'name' => 'photo_name',
'accept' => 'jpeg|jpg|gif|png',
'duplicate' => 'File is not existed!',
'denied' => 'Not images', // useful,
'htmlOptions' => array(
'style' =>'color: transparent;',
),
));
?>
And in the contoller
$images = CUploadedFile::getInstancesByName('photo_name');
foreach ($images as $image => $pic) {
//----------------- Renaming image before uploading
$extension = $pic->getExtensionName();
$newName = "image_".$adModel->id;
$newName .= "_".$imgCount.".".$extension;
$imgCount++;
if ($pic->saveAs($newPath.$newName)) {
// add it to the main model now
$img_add = new AdsPhotosTbl;
$img_add->photo_name = $newName;
$img_add->ad_id = $adModel->id;
$img_add->status = 1;
if(!$img_add->save()){
$error = true;
$upload_error = true;
break;
}
}else{
$upload_error = true;
$error = true;
break;
}
}
