How can I add page numbers to PDFKit generated PDFs?
I have multiple pages generated using PD开发者_StackOverflowFKit. How can I add page numbers to the bottom?
PDFKit.configure do |config|
config.default_options = {
header_right: "Page [page] of [toPage]"
}
end
kit = PDFKit.new(body_html)
Read all detailed documentation here:
http://madalgo.au.dk/~jakobt/wkhtmltoxdoc/wkhtmltopdf-0.9.9-doc.html
PDFKit is just a wrap up for wkhtmltopdf application that is written in C.
you need to specify a footer like this:
kit = PDFKit.new(your_html_content_for_pdf, :footer_html => "#{path_to_a_footer_html_file}")
then in the footer file have this:
<html>
<head>
<script type="text/javascript">
function subst() {
var vars={};
var x=document.location.search.substring(1).split('&');
for(var i in x) {var z=x[i].split('=',2);vars[z[0]] = unescape(z[1]);}
var x=['frompage','topage','page','webpage','section','subsection','subsubsection'];
for(var i in x) {
var y = document.getElementsByClassName(x[i]);
for(var j=0; j<y.length; ++j) y[j].textContent = vars[x[i]];
}
}
</script>
</head>
<body style="margin: 0;" onload="subst();">
Page <span class="page"></span> of <span class="topage"></span>
</body>
</html>
elements of classes 'frompage','topage','page','webpage','section','subsection','subsubsection' will get substituted with the appropriate data
I did page number with PDFKit, just by adding this:
%meta{:name => 'pdfkit-footer_right', :content => "[page]"}
in my haml file, in my RoR project.
For some weird reason, ( perhaps because I'm using slim ) - I have to use single quotes around the content, instead of double quotes - or else it attempts to escape the brackets and raw text "[page]" shows up, so try single quotes if you run into this issue with your pages.
