DOMPDF doesn't work with external css file
I'm using Zend Framework and DOMPDF library. When I test it with inline css everything works perfectly. But when I tried to move css code to the external file rules are not applied to the html page.
Here is my code.
- Code of controller's action, which generate pdf
require_once("DomPdf/dompdf_config.inc.php");
$this->_helper->layout->disableLayout();
$html = $this->view->render('index/dom.phtml');
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$pdfContent = $dompdf->output();
file_put_contents('sample.pdf', $pdfContent);
die("test");
2.Code of corresponding view (index/dom.phtml)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<link type="text/css" href="/themes/css/pdf.css" rel="stylesheet" media="screen"/>
</head>
<body>
<div>Tamara testing</div>
<table border="1">
<tr>
<th>Column 1</th>
<th>Column 2</th>
</tr>
<tr>
<td>Value 1</td>
<td>Value 2</td>
</tr>
</table>
</body>
</html>
3.And my css file:
div {color: red;}
How to make it works?
UPDATE:
To make it works I changed the following things:
1.In controller's action add base path for external files
$dompdf->set_base_path(APPLICATION_PATH."/../public/themes/css/");
2.In view change href attribute of the link tag. Make it relative to the base path set in step 1.
<link type="text/css" href="pdf.css" rel="stylesheet" />
Answer
This has in fact nothing to do with Zend Framework, but you need to supply DomPDF the right path to load the "external" files from.
$dompdf = new DOMPDF();
$dompdf->setBasePath(realpath(APPLICATION_PATH . '/path/to/css/'));
$dompdf->loadHtml($html);
$dompdf->render();
See also the manual of DomPDF for this feature.
