Image upload with zend framework

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');
    }

    /**
     * Upload Action action
     *

    public function uploadAction()
    {
        $path = "uploads/user-images/";
        $shortPath = "uploads/user-images/resize/";
        function getExtension($str)
        {

            $i = strrpos($str,".");
            if (!$i) {
                return "";
            }

            $l = strlen($str) - $i;
            $ext = substr($str,$i+1,$l);
            return $ext;
        }

        $em = $this->getEntityManager();

                if(strlen($name))
                {
                    $ext = getExtension($name);
                    //echo $ext;exit;
                    if(in_array($ext,$valid_formats))

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);
}

Answer 2

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);
