Problems using dompdf and codeigniter
Question
I have started experimenting with codeigniter and pdfs. I'm using the latest version of both. For some reason, i'm getting this error when trying to render the pdfs:
Warning: require_once(C:\Users\Manfred\Dropbox\Web\Alodu\application\helpers\dompdf/include/ci_exceptions.cls.php) [function.require-once]: failed to open stream: No such file or directory in C:\Users\Manfred\Dropbox\Web\Alodu\application\helpers\dompdf\dompdf_config.inc.php on line 208
Fatal error: require_once() [function.require]: Failed opening required 'C:\Users\Manfred\Dropbox\Web\Alodu\application\helpers\dompdf/include/ci_exceptions.cls.php' (include_path='.;C:\php\pear') in C:\Users\Manfred\Dropbox\Web\Alodu\application\helpers\dompdf\dompdf_config.inc.php on line 208
Code used is:
function pdf()
{
$this->load->helper(array('dompdf', 'file'));
// page info here, db calls, etc.
/*
$data=array(
"$title"=>"Hello!",
"$test_questions"=>"1,2,3,4",
);
*/
$data['test_questions']= "hello";
$html = $this->load->view('pdf/test_ibdp', $data, true);
$filename="Test".$data['test_questions'];
pdf_create($html, $filename);
write_file('name', $data);
}
And the helper:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
function pdf_create($html, $filename, $stream=TRUE)
{
require_once("dompdf/dompdf_config.inc.php");
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->set_paper("a4", "portrait" );
$dompdf->render();
$dompdf->stream($filename . ".pdf");
}
?>
and the view (pure HTML)
<html>
<head>
<title>Hello!</title>
</head>
<body>
<h1>HelloAgain</h1>
</body>
</html>
Any suggestions? I'm not that experienced in PHP and i'm quite confused. I just re-downloaded the library, i've tried keeping it really simple by stripping away extras in my code. Nothing seems to work. any help would be great :)

This is a class autoloader issue. Which version of DOMPDF do you use? I think dompdf 0.5 had a problem when integrated inside a framework like CI. The 0.6 version doesn't have this probleme anymore, and if the problem persists, write
define("DOMPDF_AUTOLOAD_PREPEND", true)
in dompdf_config.custom.inc.php .

Correct the dompdf file path. Also remove this line of code:
write_file('name', $data);
The following line is enough:
pdf_create($html, $filename);

The error is saying the path below is not correct. Recheck the path
require_once("dompdf/dompdf_config.inc.php");

Path to the file is incorrect.
C:\\Users\\Manfred\\Dropbox\\Web\\Alodu\\application\\helpers\\dompdf / include / ci_exceptions.cls.php
You can use DIRECTORY_SEPARATOR .
