Getting error with DOMPDF on Codeigniter 2 + dompdf-0.5.2 - El Forum - 04-09-2011
[eluser]Unknown[/eluser]
Hello dear friends.
I am new here, this is my first post!
I am trying to use the DOMPDF to generate PDF files, but i am getting an error.
My script works like that:
We get the data from the database, use a parser to parse the view model and output it to the PDF (as everyone do).
My code:
Code:
$dados = array(
'nome' => $nome,
'nome_guerra' => $nome_guerra
);
$this->load->helper('to_pdf');
$html = $this->parser->parse('relacoes/modelos/teste', $dados, TRUE);
pdf_create($html, 'filename');Of course the variables from $dados have been declared before
The error i receive is:
Fatal error: Uncaught exception 'PDFlibException' with message 'Cannot modify header information - headers already sent by (output started at C:\xampplite\htdocs\codeigniter\system\helpers\to_pdf_helper.php:18)' in C:\xampplite\htdocs\codeigniter\system\helpers\dompdf\include\pdflib_adapter.cls.php:833 Stack trace:

Has anyone experienced this kind of problem, and can anyone help with this, tell me what is hapening?
Obs: I am using a local XAMPP server on Windows 7
Thank you very much.

I get an error too:
Warning: require_once(/Applications/MAMP/htdocs/extranet/application/helpers/dompdf/include/ci_exceptions.cls.php) [function.require-once]: failed to open stream: No such file or directory in /Applications/MAMP/htdocs/extranet/application/helpers/dompdf/dompdf_config.inc.php on line 208

No idea why. dompdf doesn't even have a file called ci_exceptions.cls.php

@Muni It appears that your helper "to_pdf_helper.php" has already output a header (possibly an error) prior to calling the dompdf output. That's where you need to start looking.
Also as a side note. Do you really want to be putting custom helpers in the codeigniter system folder? You could have problems when you update future versions of codeigniter

I have solved this problem by creating ci_exceptions.cls.php,an empty php file in that directory and i am not getting errors anymore.I dont know whether it is right way bt it is working well and not showing errors now

Code:
$this->load->helper(array('dompdf', 'file'));
$data['title']='PDF Printing';
$html=$this->load->view('viewfile_name',$data, true);
pdf_create($html, 'filename');Quote:?> at the end of controller files will be causing the modify header error.
