I didn't manage to find an upload progress plugin or wiki page so I'll try one. My solution is based on a lot's of plugins so I can understand it might not be the best one.

Dependencies

• sfUJSPlugin: Provides helpers for unobstrusive scripting
• http://digitalbush.com/projects/progress-bar-plugin jquery plugin for progressbar
• PHP 5.2 with APC ! Yes the php accelerator has a new feature since php 5.2 that will let you monitor POST request
• JSON PHP extension (default with PHP 5.2 but might be in a separate package depending on distribution)

Configuration

I have simply installed the plugins above, nothing special to be done, just following the wiki/html documentation pages.

jquery.progressbar I've copy/paste the css into "web/css/progressbar.css" and downloaded the js file into "web/js/jquery.progressbar.js" (I've rename it with the . dot to be conform with jquery plugin naming convention)

APC after installing apc either from you distribution package or from pecl (i.e howto ), then it's very important : to activate the apc monitoring feature just add "apc.rfc1867 = on" to your php.in or apc.conf file.

big file upload for big file upload (>2M):

you should play a bit with these php.ini settings: upload_max_filesize|post_max_size|max_execution_time|memory_limit

you might also check apache settings (if apache used): LimitRequestBody

code example

I use a very simple behaviour for my site but you'll be able to extend this example easily. I decided to use one unique action/template for all the upload module

the action

don't forget to modify the redirect <your_module>

<?php
  /**
   * Executes upload action
   *
   */
  public function executeUpload()
  {

      if ($this->getRequest()->getMethod() == sfRequest::POST)
      {
          if ($this->getRequest()->hasFiles())
          {
              foreach ($this->getRequest()->getFileNames() as $fileName)
              {
                  $fileSize  = $this->getRequest()->getFileSize($fileName);
                  $fileType  = $this->getRequest()->getFileType($fileName);
                  $fileError = $this->getRequest()->hasFileError($fileName);
                  $fileRealName = $this->getRequest()->getFileName($fileName);
                  $uploadDir = sfConfig::get('sf_upload_dir');
                   
                  $this->getRequest()->moveFile('test_file', $uploadDir.'/'.$fileRealName);
                  $msg =  "file uploaded ** $fileSize ** $fileType ** $fileError ** $fileRealName ** $uploadDir";
              }
          }else{
              $msg = "no file uploaded";
          }
          $this->setFlash('message',$msg);
          $this->redirect('/<your_module>/upload');
      } else if( ($progressKey = $this->getRequestParameter('progress_key')) != null ) {
          $status = apc_fetch('upload_'.$progressKey);
          $this->renderText( json_encode($status) );
          return sfView::NONE;
      }
      //finally
      return sfView::SUCCESS;
  }

the view don't forget to modify the getJSON <your_module>

<?php use_helper('UJS') ?>
<?php use_javascript('/js/jquery.progressbar.js') ?>

<div id='flash'>
<?php echo $sf_flash->get('message') ?>
</h1>
</div>
<?php $uniqId = uniqid() ?>
<form enctype="multipart/form-data" id="upload_form" action="" method="POST">
   <input type="hidden" name="APC_UPLOAD_PROGRESS" id="progress_key" value="<?php echo $uniqId?>" />
   <input type="file" id="test_file" name="test_file" /><br />
   <input type="submit" id="submit" value="Upload!" />
</form>

<div id='progressbar' style='display: none'/>

 <?php UJS('
$("#submit").click(function() {
setInterval("$.getJSON(\'/<your_module>/upload\', { progress_key: \''.$uniqId.'\'}, function JSON(json){$(\'#progressbar\').show();$(\'#progressbar\').reportprogress(eval(json.current/json.total*100));} )", 1000)
});
'); ?>

stylesheet Don't forget to include the css into the view.yml

uploadSuccess:
  stylesheets:     [progressbar]

That's it ! Hope someone will find it usefull...

By the way thanks very much to Francois and other who contribute to th UJS/PJS/JQuery plugin which is simply incredible.

Note: this version is a very basic version, you could enhance it by using iframe and monitor the upload start/end instead of onclick/redirect tips used here... but hope someone might contribute and enhance this page ...
