INSTRUCTIONS: Download an appropriate version of wkHTMLtoPDF library from http://wkhtmltopdf.org. If you are on Windows operating system then do install it under C:\ drive (for example c:\wkhtmltopdf). On Linux/UNIX, you can install it under /usr/local/bin and make sure wkhtmltopdf has execute permissions.
Open a command prompt window. The syntax for using the tool is fairly simple, enter the name wkhtmltopdf, followed by the URL of the web page, and the name of the PDF that you want to create, like so. Let's say you want to save a copy of a website, this is what the command will look like.
Footers And Headers: Headers and footers can be added to the document by the --header-* and --footer* arguments respectively. In header and footer text string supplied to e.g. --header-left, the following variables will be substituted.
Lets say you have a footer my_footer.html which contains the following:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script>
function substitutePdfVariables() {
function getParameterByName(name) {
var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}
function substitute(name) {
var value = getParameterByName(name);
var elements = document.getElementsByClassName(name);
for (var i = 0; elements && i < elements.length; i++) {
elements[i].textContent = value;
}
}
['username'/*, 'topage', 'page',.. etc and any variable you would want to replace */]
.forEach(function(param) {
substitute(param);
});
}
</script>
</head>
<body onload="substitutePdfVariables()">
<span class="username"></span>
</body>
</html>
You can replace "username" with some value:
wkhtmltopdf my_super_html.html --footer-html my_footer.html --replace "username" "Veaer"
Notice that I used javascript to replace the named variable with my value.
