Zend Framework how to set headers

Question

I have a question, how can I do something like this:

header(\"Content-Disposition: inline; filename=result.pdf\"); 
header(\"Content-type: application/x-pdf\         


        

Answer 1

I had a header set. It was not set, but ADDED. So I had a Content-Type of text/html and also application/pdf.

Flagging the Content-Type with TRUE made the download possible in IOS and other devices which showed only cryptic symbols after the download or an error:

->setHeader('Content-type', 'application/x-pdf', true);

setHeader($name, $value, $replace = false)

from: https://framework.zend.com/manual/1.12/de/zend.controller.response.html

Answer 2

Your statement to set the response headers is slightly malformed:

$this->getResponse()
     ->setHeader('Content-Disposition', 'inline; filename=result.pdf')
     ->setHeader('Content-type', 'application/x-pdf');

The above should work - please note the difference in the Content-Disposition-header.

By the way... When you want to force a download box (instead of loading the document in the browser) you should use the Content-Disposition attachment.

$this->getResponse()
     ->setHeader('Content-Disposition', 'attachment; filename=result.pdf')
     ->setHeader('Content-type', 'application/x-pdf');

Depending on the browser it may be possible that you also have to set the Content-Length or change the Content-type to a combination (multiple headers) of one or more of application/force-download, application/octet-stream and/or application/download. And as I wrote in the comment sometimes caching headers may interfere with your download. Check to see which caching-headers are sent.

Solved

        $this->getResponse()
         ->setHeader('Content-Disposition:inline', ';filename=result.pdf')
             ->setHeader('Content-Type', 'application/x-pdf');

Answer 4

Late to the table, I can recommend this action helper as a simple, reusable component for sending files or in memory data to the browser.

Has options for caching, disposition and can utilise Apache Sendfile

Answer 5

My guess is that you're doing something like:

$this->getResponse()
        ->setHeader('Content-Disposition:inline', ' filename=result.pdf')
        ->setHeader('Content-type', 'application/x-pdf');
fpassthru($filename);
exit();

or something.

The response here will never be rendered (which renders the headers). The response is rendered during post-action printing, usually.

You will have to directly set the headers (as you noted in the non-oo code), or use $this->getResponse()->sendHeaders() directly.
