codeigniter - Dompdf generated pdf is 0 bytes -


i trying save pdf disk.

i using dompdf , codeigniter below: 

$this->load->helper('dompdf','file'); $this->load->helper('file'); $saveto = './labels';  $data['id'] = $this -> uri -> segment(3); $data['no_of_prints'] = $this -> uri -> segment(4);    $labelname = "label". $data['id'] ."-". $data['no_of_prints'] . ".pdf"; $html = $this->load->view('label_view', $data, true); file_put_contents($saveto."/".$labelname, pdf_create($html, $labelname));

while labelname gets generated correctly. file saved disk reads 0 bytes , expected adobe reader cannot open file ... error.

i using fancybox 2.0 popup pdf , when right click on popup,(the pdf not show, i'm guessing pdf plugin issues) able save as readable pdf not 0 bytes.

it important application save pdf disk automatically. how save readable pdf disk?

thanks.

i have found old ci code (pre version 2) used dompdf, had parameter write file.
different yours?

<?php if (!defined('basepath')) exit('no direct script access allowed'); function pdf_create($html, $filename, $stream=false, $orientation='portrait') {     require_once("dompdf/dompdf_config.inc.php");     spl_autoload_register('dompdf_autoload');      $dompdf = new dompdf();     $dompdf->set_paper( array(0,0, 2.175 * 72, 3.375 * 72), "landscape" ); // credit card size     $dompdf->load_html($html);     $dompdf->render();     if ($stream)     {         $dompdf->stream($filename.".pdf");     }     else     {         $ci =& get_instance();         $ci->load->helper('file');         write_file("./uploads/$filename.pdf", $dompdf->output());     } } ?>
