Witam Używam DOMPDF do generowania pliku PDF, chciałbym wiedzieć, jak uzyskać numer strony.

Wypróbowałem następującą wzmiankę na stronie FAQ DOMPDF. i nie udało się. UWAGA: Włączam także PHP inline, jak również wspomnę o tym w FAQ

następujący kod to mój kod

 <?php
require_once("dompdf/dompdf_config.inc.php");


ob_start();
//be sure this file exists, and works outside of web context etc.)


$dompdf = new DOMPDF();


$html="     <script type='text/php'>";
        if ( isset($pdf) ) { 
            $font = Font_Metrics::get_font("yourfont", "normal");
            $size = 9;
            $y = $pdf->get_height() - 24;
            $x = $pdf->get_width() - 15 - Font_Metrics::get_text_width("1/1", $font, $size);
            $pdf->page_text($x, $y, "{PAGE_NUM}/{PAGE_COUNT}", $font, $size);
        } 
$html.="        </script>";

$html .="
        aaaaa<br/>aaaaaa<br/>aaaaaa<br/>aaaaa<br/>aaaaaa<br/>aaaaaa<br/>aaaa<br/>aaaaa<br/>aaaaaa<br/>aaaaa<br/>
        aaaaa<br/>aaaaaaa<br/>aaaaaa<br/>
aaaaa<br/>aaaaaa<br/>
        aaaaaaa<br/>aaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
        aaaaaaa<br/>aaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
        aaaaaaaa<br/>aaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
        aaaaaaaa<br/>aaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
        aaaaaaaa<br/>aaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
        aaaaaaaaa<br/>aaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
        aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
        </body></html>"; 


$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");


 ?>

Czy ktoś może mi wskazać ten problem? skąd to zrobiłem źle
