wicked_pdf: Is it possible to have the header only show on the first page & the footer only on the last?

Question

Right now I have :header => {:html => {:template => \"layouts/pdf_header.html.erb\"}} setting things up. Is there something I can pass in that will on

Answer 1

Some quick javascript can take care of this. Follow the boilerplate laid out under 'Footers And Headers' on wkhtmltopdf

These are your header and footer templates respectively. The key variable to keep track of is 'page' which is available from URL hash. Your header will look something like this:

<div class="headerContent" style="display:none">
   ...my awesome html
    <hr />
</div>
<script type="text/javascript">
    var headerCheck = function() {
      var x=document.location.search.substring(1).split('&');
      for (var i in x) {
        if(x[i] == "page=1")
          document.getElementsByClassName("headerContent")[0].style.display = "block";
       }
     }();
</script>

Similarly for your footer the code will look something like this:

<div class="footerContent" style="display: none">
    ...awesome footer html
</div>
<script type="text/javascript">
    var footerCheck = function() {
       var x=document.location.search.substring(1).split('&');
       var currentPage = 1;
       for (var i in x) {
         var z=x[i].split('=',2);
         if(z[0] == "page")
           currentPage = unescape(z[1]);
         if(z[0] == "topage" && currentPage == unescape(z[1]))
           document.getElementsByClassName("footerContent")[0].style.display = "block";
        }
     }();
 </script>

Add layout when rendering pdf

format.pdf do
  render :pdf => "my_pdf",
  :layout => 'pdf
end

views/layouts/pdf.haml

%html
  %head

  %body
    = render "layouts/header"
    = yield
    = render "layouts/footer"
