Image upload with zend framework - php

Question

I am new to the zend framework. I need to create a user registration with image upload. I have done that. My registration controller and upload controller works. Currently all images are uploading to uploads/user-images/ in public folder. But my actual requirement is, I have to create a specific folder for each user based on their user ID and need to upload their photos to that folder. Also, I need to store that image path in a DB as actualname_current_Timestamp_width_height.extension, but I don't know how to do this. Here I am including my controller codes:
<?php
/**
* PhotoController class file
*
* This file contains a class for PhotoController
*
* #category Zend
* #package Zend_Controller
*
*/
class PhotoController extends Daddara_Controller_BaseController
{
public $session;
function init()
{
parent::init();
$this->view->headScript()->appendFile('/resources/js/upload.js');
$this->view->headScript()->appendFile('/resources/js/jquery.min.js');
$this->view->headScript()->appendFile('/resources/js/jquery.wallform.js');
$this->view->headScript()->appendFile('/resources/js/modernizr.custom.js');
// $this->view->headScript()->appendFile('/resources/js/lightbox/jquery-1.10.2.min.js');
// $this->view->headScript()->appendFile('/resources/js/lightbox/lightbox-2.6.min.js');
}
function indexAction()
{
$this->_forward('upload');
}
/**

{

}
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
$em = $this->getEntityManager();
//User Id

Answer 1

You can create a folder with the command mkdir():
if(mkdir(APPLICATION_PATH . '/public/uploads/' . $userId)){
//dir created
}
You can move a file with copy() and unlink():
if(copy(APPLICATION_PATH . '/public/uploads/' .$filename,
APPLICATION_PATH . '/public/uploads/' .$userId .'/' .$newfilename)) {
unlink(APPLICATION_PATH . '/public/uploads/' . $filename);
}

I have tried something like the following code and thats worked for me. Now i can upload images to a purticular folder for each user based on their user id. Hope this will help someone else.. :-)
$path = "uploads/user-images/";
$em = $this->getEntityManager();
//User Id
$userId = $em->getRepository("Models\User")->findOneBy(array('id' => $this->currentUser->id));
$user_path = "$path".$userId->getId()."/";
if (!file_exists($user_path)) mkdir($user_path, 0777);
