The correct type is application pdf for PDF  not application force-download  This looks like a hack for some legacy browsers  Always use the correct mimetype if you can   If you have control over the server code    Forced download prompt  use header  Content-Disposition    attachment  filename myfilename myextension    Browser tries to open it  use header  Content-Disposition    inline  filename myfilename myextension      No control over the server code    Use the HTML5 download attribute  It uses the custom filename specified on the view side    NOTE  I prefer setting the filename on the server side as you may have more information and can use common code

If you link to a  PDF it will open in the browser  If the box is unchecked it should link to a  zip to force the download   If a  zip is not an option  then use headers in PHP to force the download  header  Content-Type  application force-download     header  Content-Description  File Transfer

You can do this in the following way    lt a href  path to PDF file  gt Open PDF lt  a gt    If the PDF file is inside some folder and that folder doesn t have permission to access files in that folder directly then you have to bypass some file access restrictions using  htaccess file setting by this way    lt FilesMatch       jpe g JPE G gif GIF png PNG swf SWF pdf PDF     gt      Order Allow Deny     Allow from all  lt  FilesMatch gt    But now allow just certain necessary files   I have used this code and it worked perfectly

To indicate to the browser that the file should be viewed in the browser  the HTTP response should include these headers   Content-Type  application pdf Content-Disposition  inline  filename  filename pdf    To have the file downloaded rather than viewed   Content-Type  application pdf Content-Disposition  attachment  filename  filename pdf    The quotes around the filename are required if the filename contains special characters such as filename 1  pdf which may otherwise break the browser s ability to handle the response   How you set the HTTP response headers will depend on your HTTP server  or  if you are generating the PDF response from server-side code  your server-side programming language

Oops  there were typing errors in my previous post       header  Content-Type  application force-download        header  Content-type  application pdf        header  Content-Disposition  inline  filename      name           If you don t want the browser to prompt the user then use  inline  for the third string instead of  attachment    Inline works very well  The PDF display immediately without asking the user to click on Open   I ve used  attachment  and this will prompt the user for Open  Save  I ve tried to change the browser setting nut it doesn t prevent the prompt

If you are using HTML5  and I guess nowadays everyone uses that   there is an attribute called download   For example    lt a href  somepathto pdf  download  filename  gt    Here filename is optional  but if provided  it will take this name for the downloaded file
