[SOLVED] Problem with R&OS;PDF creator: Lost headers - El Forum - 07-01-2009

Hey there
I use R&OS; and I am stumbling over a problem. Unfortunately, I couldn't find any contact-address on the web-page, therefore I hope somebody here solved it already.
I set the headers as follow:
Code:
$this->CI->output->set_header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // some day in the past to avoid cached files
$this->CI->output->set_header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
$this->CI->output->set_header("Content-type: application/pdf"); // It is a pdf...
$date = gmdate("d.m.Y") . "_" . date("H_i");
$this->CI->output->set_header("Content-Disposition: attachment; filename=".$fileName."_".$date.".pdf");
$this->CI->output->set_header("Content-Transfer-Encoding: binary");Basically, it will prevent caching, the browser would pop up a nice save or open dialog, and the pdf gets a nice name.
This works, until the pdf-class needs to generate another page due to long (dynamic) contents. Then it seems that I loose the headers, the pdf opens within the browser, no nice name when I want to save it.
I looked for any echo-statements in the pdf-class, nothing.
Has anybody encountered this before?
Thx for any tipps, if any...
Oliver

okay, after playing around I figured out that it was a classical output before header, because I was simply echoing the pdf-stream in my library. d'oh!
That's how it should be used correctly:
Code:
$this->CI->output->set_header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // some day in the past to avoid cached files
$this->CI->output->set_header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
$this->CI->output->set_header("Content-type: application/pdf"); // It is a pdf...
$date = gmdate("d.m.Y") . "_" . date("H_i");
$this->CI->output->set_header("Content-Disposition: attachment; filename=".$fileName."_".$date.".pdf");
$this->CI->output->set_header("Content-Transfer-Encoding: binary");
$pdfStream = $this->CI->cezpdf->ezOutput();
$this->CI->output->set_output($pdfStream);It is then in the hands of CI to set the headers and send the content after!
By the way: If you don't want to set your headers yourself, you can use
Code:
$this->CI->cezpdf->ezStream();
