Hello all,
I am having issues using the DOMPDF pdf generation library in my
Cake 2.1 application. I am building an inventory management
application for use at my company and I am trying to dynamically
generate pdfs my users can print as stock labels. However, when I
attempt to stream to pdf in my view I get a "Headers already sent"
error. I have already removed all leading and trailing spaces from
the view and the DOMPDF include file. I am also using the ajax layout
which does not preface the content with any html markup. I guess that
cake is sending headers somewhere in the view rendering process that I
can't see. Below is the code for my controller function and my view:
Controller method:
public function printSingleLabel($id = null){
if($id === null){
$this->Session->setFlash('No ID provided to print label');
$this->redirect(array('action'=>'index'));
}else{
$this->set('stockItem', $this->StockItem->find('first',
array(
'recursive'=>3, 'conditions'=>array(
'StockItem.id'=>$id
)
)));
$this->set('quantity', 15);
$this->render('printSingleLabel', 'ajax');
}
}
View file:
<?
require_once("dompdf/dompdf_config.inc.php");
$html = <<<EOD
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html;
charset=UTF-8">
<style>
@page {
margin: 0in 0in 0in 0in;
}
body {
margin: 0in;
padding: 0in;
font-size:8pt;
font-family: Arial, Sans-Serif;
}
div {
float:left;
/*width:2.75in;*/
padding:0in;
/*height:2.125in;*/
margin:0in;
}
div.center {
margin-left: 0.135in;
margin-right: 0.135in;
}
</style>
</head>
<body>
<div>
<strong>{$stockItem['Part']['number']} Rev {$stockItem['StockItem']
['revision']}</strong>
<br/>
{$stockItem['Part']['name']}
<br/>
<strong>Lot/Batch:</strong>{$stockItem['StockItem']['lot']}/
{$stockItem['StockItem']['batch']}<br/>
<strong>Expires:</strong>{$stockItem['StockItem']['exp_date']}<br/
>
<strong>Status:</strong>{$stockItem['Status']['code']}<br/>
<strong>Quantity:</strong>$quantity{$stockItem['Part']['Uom']
['code']}<br/>
</div>
</body></html>
EOD;
$pdf = new DOMPDF();
$pdf->set_paper(array(0,0,153,198), 'landscape');
$pdf->load_html($html);
$pdf->render();
$pdf->stream("sample.pdf", array('Attachment'=>0));
I've spent a whole afternoon trying to track down where the headers
are being sent with no luck. If anyone has a suggestion I'd greatly
appreciate it.
