manuelle · #1 (**permalink**) 03/05/2011, 08:28

hola comunidad estoy tratando de usar la libreria HTML_ToPDF pero me da un problemita, cuando le doy en el boton exportar me sale en el firefox, la opcion de abrir o guardar el pdf pero me sale dos veces, en la primera dice "de: localhost" y en la segunda "de: /temp" he tratado de arreglar esto pero no se como hacerlo, si alguien puede mirarme el codigo a ver que tengo mal se lo agradecere.

esta es la clase prueba.php

Código:

<?php

require_once '/../HTML_ToPDF/HTML_ToPDF.php';

class HTML_PDF
{
    public static function Rerderizar()
    {
	$html = $_POST['html'];
        $linkToPDFFull = $linkToPDF = tempnam(dirname(__FILE__), 'PDF-');

        unlink($linkToPDFFull);
        $linkToPDFFull .= '.pdf';
        $defaultDomain = 'localhost';

        $pdf = new HTML_ToPDF($html, $defaultDomain);

        $result = $pdf->convert();

        if (is_a($result, 'HTML_ToPDFException'))
        {
            die($result->getMessage());
        }
        else
        {
            copy($result, $linkToPDFFull);
            unlink($result);
        }

        header("Cache-control: private");
        header("Expires: ".gmdate("D, d M Y H:i:s", mktime(date("H")+2, date("i"), date("s"), date("m"), date("d"), date("Y")))." GMT");
        header("Cache-Control: no-cache, must-revalidate");
        header("Pragma: no-cache");
        header('Content-Type: application/pdf');
        header('Content-Disposition: attachment; filename="example.pdf"');
        readfile($linkToPDFFull);
        unlink($linkToPDFFull);
    }

}

?>

esta es la pagina que queremos exportar

Código:

<?php ob_start() ?>
