no pdf output

[Tikaa]

please delete. sorry for double posting

[Cristian Gómez]

Do you have the id property setted like that? without
the double quotes?? Maybe that can be an issue, also try concatenating all
the table HTML into $table string instead of make ob_get_clean (don't trust
me in this but I think that other HTML output isn't well supported by tcpdf)

i have this table generated by php and styled html inside patients.php
file:

<form name="pt_list" action="classes/MYPDF.php" method="post">
<input type="submit" name="pt_pdf" value="Download as PDF">
</form>

<?php $x=1;
foreach ($users as $patient) {

?>

['username'];?>"><?php echo $patient['username'];?>http://sourceforge.net/../profile.php?username=%3C?php%20echo%20$patient%3Cspan%3E['username']%3C/span%3E;?%3E
<?php echo $patient['id'];?>
<?php echo $patient['name'];?>
<?php echo $patient['joined'];?>

<?php $x++; } ?>

Pt. username	Pt. number	Full Name	Added on

<?php$GLOBALS['table'] = ob_get_clean();$table = $GLOBALS['table'];
?>
<?php

echo $table;

the table outputs fine on patients.php.i am trying to offer this table as
a downloadable pdf for users but for the past few days i cant get it to
output. here is what i tried in MYPDF.php:

require_once('../tcpdf/tcpdf.php');require('../patients.php');

// Extend the TCPDF class to create custom Header and Footer
class MYPDF extends TCPDF {

//Page headerpublic function Header() {
// Logo
$image_file = K_PATH_IMAGES.'logo_example.jpg';
$this->Image($image_file, 10, 10, 15, '', 'JPG', '', 'T', false, 300, '', false, false, 0, false, false, false);
// Set font
$this->SetFont('helvetica', 'B', 20);
// Title
$this->Cell(0, 15, '<< TCPDF Example 003 >>', 0, false, 'C', 0, '', 0, false, 'M', 'M');}
// Page footer
public function Footer() {
// Position at 15 mm from bottom
$this->SetY(-15);
// Set font
$this->SetFont('helvetica', 'I', 8);
// Page number
$this->Cell(0, 10, 'Page '.$this->getAliasNumPage().'/'.$this->getAliasNbPages(), 0, false, 'C', 0, '', 0, false, 'T', 'M');}

}

// create new PDF document
$pdf = new MYPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true,
'UTF-8', false);

// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example 003');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');

// set default header data
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH,
PDF_HEADER_TITLE, PDF_HEADER_STRING);

// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));

// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);

// set margins
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);

// set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);

// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);

// set some language-dependent strings (optional)
if (@file_exists(dirname(FILE).'/lang/eng.php')) {
require_once(dirname(FILE).'/lang/eng.php');
$pdf->setLanguageArray($l);
}

// ---------------------------------------------------------

// set font
$pdf->SetFont('times', 'BI', 12);

// add a page
$pdf->AddPage();

// set some text to print

// print a block of text using Write()
$pdf->writeHTML($GLOBALS['table'], true, false, true, false, '');

// ---------------------------------------------------------

//Close and output PDF document
$pdf->Output('example_003.pdf', 'D');

however, when i click the submit button all i get is a blank page no pdf
download. please any input is appreciated.

Start by turning on all php error messages.

I suspect you'll get an error that will show where your problem is.
