Header in PDF page using DOMPDF in PHP
I am 开发者_StackOverflow社区creating a PDF file using DOMPDF. I have a big content to extract in PDF, we need some header in all the pages. So can anyone telme how to add a header and footer in the PDF so that the header will shown in all the pages using DOMPDF.
In the 0.6.0 code you will be able to use HTML+CSS to generate headers and footers. There are a few limitations when compared to using inline PHP (e.g. no PAGE_COUNT placeholder yet), so whether or not this is viable depends on your needs.
The following code will produce a two-page document with a header and footer:
<html>
<head>
<style>
@page { margin: 180px 50px; }
#header { position: fixed; left: 0px; top: -180px; right: 0px; height: 150px; background-color: orange; text-align: center; }
#footer { position: fixed; left: 0px; bottom: -180px; right: 0px; height: 150px; background-color: lightblue; }
#footer .page:after { content: counter(page, upper-roman); }
</style>
<body>
<div id="header">
<h1>Widgets Express</h1>
</div>
<div id="footer">
<p class="page">Page </p>
</div>
<div id="content">
<p>the first page</p>
<p style="page-break-before: always;">the second page</p>
</div>
</body>
</html>
You could also use a combination of the two styles if you needed access to some of the missing functionality. PDF objects and text added using the page_text method render on top of the HTML content.
There is a FAQ entry on the DOMPDF wiki: Is there a way to add headers and footers or page numbers?.
So you can either add the following "inline PHP"-snippet to your HTML-input (add a similar page_text-call for your footer):
<script type="text/php">
if ( isset($pdf) ) {
$font = Font_Metrics::get_font("helvetica", "bold");
$pdf->page_text(72, 18, "Header: {PAGE_NUM} of {PAGE_COUNT}",
$font, 6, array(0,0,0));
}
</script>
If you rather want to implement this on your caller-side (meaning in the PHP code directly) you have to call the DOMPDFS's get_canvas()-method which returns the underlying PDF-Renderer which allows you to call the page_text method like in the example above. Let me show you what I mean:
// your dompdf setup
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
// add the header
$canvas = $dompdf->get_canvas();
$font = Font_Metrics::get_font("helvetica", "bold");
// the same call as in my previous example
$canvas->page_text(72, 18, "Header: {PAGE_NUM} of {PAGE_COUNT}",
$font, 6, array(0,0,0));
Eventually you have to call page_text after load_html (just try it out).
If you want to get something similar to:
Define as follows, header, footer and content of your document:
<html>
<head>
<style>
@page {
margin: 100px 25px;
}
header {
position: fixed;
top: -60px;
height: 50px;
background-color: #752727;
color: white;
text-align: center;
line-height: 35px;
}
footer {
position: fixed;
bottom: -60px;
height: 50px;
background-color: #752727;
color: white;
text-align: center;
line-height: 35px;
}
</style>
</head>
<body>
<header>
Header
</header>
<footer>
Footer
</footer>
<main>
<!-- Your main content -->
</main>
</body>
</html>
