jquery:

        $.post(url+"/create_pdf",js,function(data){

        },"json");

You can't use ajax to let the browser show the "download" file dialog. But there's [a workaround using a hidden ](http://stackoverflow.com/questions/3599670/ajax-file-download-using-jquery-php). Maybe that solves your Problem. — vstm, Jun 21 '12 at 11:49

Instread of $.post() (which will run the PDF gnerator and return contents to AJAX), you should redirect the user to the url in the browser: i.e. use

window.location.href=url+"registration/create_member?" + $.param(js);

You will need to convert your PDF generating function to accept $_GET, not $_POST

Alternatively, generate the pdf file as you are doing but store on server (temporarily) and pass the url back through ajax, Then ajax redirects the user to that temporary file location through windows.location.href instead.

But it is not taking the value of json? rather it displays blank except the labels – dude Jun 21 '12 at 11:55
Have you set the php to accept get variables as opposed to post? $this->input->get – Robbie Jun 21 '12 at 11:59
