Re: [fw-general] How to return a file directly by an action

Wed, 18 Apr 2007 04:45:22 -0700 

Hello there,

I guess this could help you.
The way I did it was by making streamAction() in my controller that looks like this: 

   function streamAction()
   {
       $fileString = $this->_request->getParam("fileString");
       $dldFileName = $this->_request->getParam("fileName");

       $disposition = $this->_request->getParam("fileDisposition"); // 
can be "inline" or "attachment"

       $contentType = $this->_request->getParam("fileMime");

       if ($this->_request->get("HTTPS") !== null) {
           $this->_response->setHeader("Pragma", "");
           $this->_response->setHeader("Cache-Control", "");

           $this->_response->setHeader("Expires", "Mon, 1 Jan 2000 
00:00:00 GMT");
           $this->_response->setHeader("Last-Modified", gmdate("D, d M 
Y H:i:s") . " GMT");
           $this->_response->setHeader("Cache-Control", "no-store, 
no-cache, must-revalidate"); // HTTP/1.1
           $this->_response->setHeader("Cache-Control", "post-check=0, 
pre-check=0");

       } else if ($disposition == "attachment") {
           $this->_response->setHeader("Cache-control", "private");
       } else {

           $this->_response->setHeader("Cache-Control", "no-cache, 
must-revalidate");

           $this->_response->setHeader("Pragma", "no-cache");
           $this->_response->setHeader("Expires", "0");
       }

       $agent = trim($this->_request->get("HTTP_USER_AGENT"));
       if ((preg_match('|MSIE ([0-9.]+)|', $agent, $version)) ||

           (preg_match('|Internet Explorer/([0-9.]+)|', $agent, 
$version))) {


           if    ($disposition == "attachment")

               $this->_response->setHeader("Content-Type", 
"application/x-msdownload");

           else
               $this->_response->setHeader("Content-Type", $contentType);

           if ($version == '5.5') {

               $this->_response->setHeader("Content-Disposition", 
"filename=".$dldFileName);

           } else {

               $this->_response->setHeader("Content-Disposition", 
$disposition."; filename=".$dldFileName);

           }
       } else {
           $this->_response->setHeader("Content-Type", $contentType);

           $this->_response->setHeader("Content-Disposition", 
$disposition."; filename=" . $dldFileName);

       }

       $this->_response->setHeader("Content-Length", strlen($fileString));
       $this->_response->setHeader("Content-transfer-encoding", "8bit");
       $this->_response->setHeader("Connection", "close");

       $this->_response->setBody($fileString);

       $this->render();

   }

And than forward to it from wherever i need it like so:

$this->_forward("stream", "pdf", null, array("fileString" => $pdf->render(),
                                            "fileName"   => $pdfFile,

                                            "fileDisposition"   => 
"inline",
                                            "fileMime"   => 
"application/pdf",

                                            ));


The code in streamAction takes care of everything, and works in IE5.5, 
6.0+, Mozilla, Opera (as far as i could test) and over http as well as 
https protocol.

Hi all,

I have an action that make a mysql database backup in this way:

     public function backupDatabaseAction()

    {   
        $db = Zend::registry('db');         $view = 
Zend::registry('view');

        $config = Zend::registry('config');
        $session = Zend::registry('session');

       
        $view->title = $config->site->title." - Modifica di una casa";
       
        $ctr = new CaseVacanzaDataController($db, $session);
    
            $view->actionTemplate = 'main.php';             
$view->header = $view->render('header.php');
                         system($config->bin_path."\export_db.bat", 
$ret);              $view->menu =  
$view->render('menu_amministrazione.php');

            $view->body = $view->render('admin_backup_database.php');

            $view->footer = $view->render('footer.php');

               
            echo $view->render('main.php');
       


    }

directory..

Hello,

this could help you maybe :

basically you could do that
       $str = file_get_contents($file);

       header('Content-Disposition: attachment; 
filename="downloaded.pdf"');

       header('Content-type: application/pdf');
       echo $str;


the example is for a pdf file, in your example, yous hould change 
Content-type (look for it in header doc) Content-Disposition: 
attachment makes the download window opens in order to save it or 
display it on the client side.



But  I guess, a "zfer" way would be to use the response object, maybe 
like this :


|$this->getResponse()
   ->setHeader('Content-Type', 'text/plain')

   ||->setHeader('|Content-Disposition|', '|attachment; 
filename="bkp.sql"'|') |

|    ->appendBody(|$str|);


Hope this could help you, though I didn't test it. At least it works 
for me with pdf files.
