Upload multiple files in array with yii - php

Question

I've created a form with field in array following this link http://www.yiiframework.com/doc/guide/1.1/en/form.table
and created a file field in array like this
echo $form->fileField($m, "[$i]myfile");
But now i've no idea what i'm going to do in controller to save the file paths and filename etc. I am able to save other information but not the upload file. I've tried with this but no luck.
$imageUpload = CUploadedFile::getInstance($models[$i],'name');

Answer 1

Try this way, but first ensure your form type is
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'user-form',
'htmlOptions'=>array(
'enctype' => 'multipart/form-data'
),
)); ?>
//Avatar Upload on controller start
$uploaded_file = CUploadedFile::getInstance($model,'avatar');
$main_image=null;
if($uploaded_file and $model->validate())
{
$main_image =time()."-".$model->username.".".$uploaded_file->getExtensionName();
$model->avatar=$uploaded_file;#initialize model attribute with file name
$model->avatar->saveAs(Yii::app()->basePath."/../images/profile-images/".$main_image);//this will upload selected image file
}
//Avatar Upload on controller end

This method need the browser support HTML5.
In view file:
$form=$this->beginWidget('CActiveForm', array(
'id'=>'ca-form',
'enableAjaxValidation'=>false,
'htmlOptions' => array('enctype' => 'multipart/form-data'),
));
...
echo $form->fileField($m, "myfile[]", array('multiple'=>true));
In Controller:
$imageUploads = CUploadedFile::getInstances($models,'myfile');
foreach ($imageUploads as $imageUpload) {
...// Here you can use $imageUpload->name.
}
Notice the 's' of getInstances
