Blank page with no errer reporting - HELP!

[fearghalm]

Hi all,

I'm trying to parse a (large) HTML table (no css, javascript etc) no
just getting a blank page...

Using the example code:


if ( isset( $_POST["html"] ) ) {

if ( get_magic_quotes_gpc() )
$_POST["html"] = stripslashes($_POST["html"]);
$_POST["html"] = str_replace("<th>","<tr>",$_POST["html"]);
$_POST["html"] = str_replace("</th>","</tr>",$_POST["html"]);


$dompdf = new DOMPDF();
$dompdf->load_html($_POST["html"]);
$dompdf->set_paper($_POST["paper"], $_POST["orientation"]);
$pdf = $dompdf->output();

exit(0);
}


But no errors to tell me whats wrong...any ideas anyone?

Two things:
1) You have not rendered the PDF, so $dompdf->output() will not return
anything.
2) You should probably be using $dompdf->stream() rather than $dompdf-
>output().

See http://www.digitaljunkies.ca/dompdf/usage.php#class for more
information.

This happened to me as well. In my case a blank page meant a rendering error. Check your server's error_log file and you might see error messages from DOMPDF basically saying "I can't render something because it's off the page".

Yeah, tried this but same result. Is
there a function to display errors?

Tried

ini_set ('display_errors', 'on');
ini_set ('log_errors', 'on');
ini_set ('display_startup_errors', 'on');
ini_set ('error_reporting', E_ALL);

but nothing. Any ideas?

Did you read what brian said? You never even rendered the document.
It was never created. You have to call the render() function.

Apologies. Yes, I did render the pdf the second time..still getting a
blank page
using the following:

$dompdf->load_html($html);
$dompdf->set_paper('a4', 'portrait');
$dompdf->render();
$dompdf->stream("dompdf_out.pdf");

The $html is large, but tables are complete and entire HTML
is valid...

A large HTML document with tables could require more memory or
execution time than is allowed on your system. You should see an error
message with "display_errors" set to on. You might want to check with
your web host to find out what you need to do to see PHP errors.

It might also be useful to know the operating system, web server, and
php version on your server.
