I have posted a tutorial on how to use uploadify with cakephp

Users can upload images with uploadify and when uploadify sends the image to my controller I simply attach the sessionid as a parameter.
Step One.
Create function on own controller 
app/controller/PagesController.php

public function index() { /* this function for show index page*/

$this->layout='home';

$this->set('title_for_layout', 'Photo Upload');

}

public function uploadify() { /* this function for upload file */

$this->autoRender=false;

$targetFolder = WWW_ROOT .'/img/'; // this folder created on webroot/ $tempFile = $_FILES['Filedata']['tmp_name'];

$targetPath = $targetFolder; $targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('jpg','jpeg','gif','png'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']);

if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile);

echo $_FILES['Filedata']['name']; } else { echo 'Invalid file type.';

} }
Step 2
create view file for display 
<h1>Uploadify Demo</h1>
<?php echo $this->Form->create(‘Setting’, array(‘url’=>’#’,’type’ => ‘file’)); ?>
<div id=”queue”></div>
<?php echo $this->Form->input(‘file_upload’,array(‘type’ => ‘file’, “id”=>’file_upload’, ‘div’=>false,’label’=>false,”multiple”=>”true”));?>
<?php echo $this->Form->input(‘police_no’,array(‘id’=>’police_no’, ‘div’=>false,’label’=>false));?>
<?php echo $this->Form->button(‘Submit’,array(‘class’=>’button’,’div’=>false,’label’=>false));?>
<script type=”text/javascript”>
<?php $timestamp = ‘phptp’;?>
$(function() {
$(‘#file_upload’).uploadify({
‘formData’     : {
‘test’ : ‘<?php ‘photoupload’;?>’,
‘token’     : ‘<?php echo md5(‘unique_salt’ . $timestamp);?>’
},
‘method’   : ‘post’,
‘fileSizeLimit’ : ‘100KB’,
‘fileTypeDesc’ : ‘Image Files’,
‘fileTypeExts’ : ‘*.gif; *.jpg; *.png’,
‘debug’    : false,
‘swf’      : ‘../img/uploadify.swf’, /* this file save into webroot/images folder*/
‘uploader’ : ‘../Pages/uploadify’, /* this function will come for controller
‘onUploadSuccess’ : function(file, data, response) {
document.getElementById(‘police_no’).value=data;
}
});
});
