我在使用 HTML2PDF 库创建 PDF 和 MySQL 时遇到问题。我想显示图像但不显示。有人知道该怎么做吗?
例如:我有以下代码:
书签.php
<?php
ob_start();
?>
<style type="text/css">
<!--
    table.page_header {width: 100%; border: none; background-color: #DDDDFF; border-bottom: solid 1mm #AAAADD; padding: 2mm }
    table.page_footer {width: 100%; border: none; background-color: #DDDDFF; border-top: solid 1mm #AAAADD; padding: 2mm}
    h1 {color: #000033}
    h2 {color: #000055}
    h3 {color: #000077}
    div.niveau
    {
        padding-left: 5mm;
    }
-->
</style>
<page backtop="14mm" backbottom="14mm" backleft="10mm" backright="10mm" style="font-size: 12pt">
    <page_header>
        <table class="page_header">
            <tr>
                <td style="width: 100%; text-align: left">
                    <img src=showimage.php alt="image" />
                </td>
            </tr>
        </table>
    </page_header>
    <page_footer>
        <table class="page_footer">
            <tr>
                <td style="width: 100%; text-align: right">
                    page [[page_cu]]/[[page_nb]]
                </td>
            </tr>
        </table>
    </page_footer>
</page>
<?php
    $content = ob_get_clean();
    require_once(dirname(__FILE__).'/../html2pdf.class.php');
    try
    {
        $html2pdf = new HTML2PDF('P', 'A4', 'en', true, 'UTF-8', 0);
        $html2pdf->writeHTML($content, isset($_GET['vuehtml']));
        $html2pdf->Output('bookmark.pdf');
    }
    catch(HTML2PDF_exception $e) {
        echo $e;
        exit;
    }
?>
显示图像.php
<?php
mysql_connect("localhost","user","pass");
mysql_select_db("db");
$rs = mysql_query("select * from gallery");
$row = mysql_fetch_assoc($rs);
$imagebytes = $row[imgdata];
header("Content-type: image/jpeg");
print $imagebytes;
?>
