Question

我正在使用Codeigniter，我成功实施了dompdf来生成PDF文件。现在我在生成的PDF中添加页眉和页脚时遇到问题。

这是我的dompdf_helper代码：

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
function pdf_create($html, $filename='', $stream=TRUE) 
{
require_once("dompdf/dompdf_config.inc.php");

$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
  $dompdf->set_paper("A4");
if ($stream) {
    $dompdf->stream($filename.".pdf",1);
} else {
    return $dompdf->output();
}
}
?>

这是我的控制器调用PDF生成：

<?php

$data['store']=$res;  
$this->load->helper(array('dompdf', 'file'));
$html = $this->load->view('store/sales_pdf', $data, true);
$html.= $this->load->view('footer');
$filename="salesbill".$id;
pdf_create($html, $filename);
$data = pdf_create($html, '', false);
write_file('name', $data); 
?>

我使用此脚本获取页码，但仅在第二页退出时打印，否则将无法打印。

  <script type="text/php">

    if ( isset($pdf) ) {

      $font = Font_Metrics::get_font("helvetica", "bold");
      $pdf->page_text(500,10, "Page: {PAGE_NUM} of {PAGE_COUNT}", $font, 6, array(0,0,0));

    }
    </script>

我想在页面中打印公司名称和联系方式以及帐单号作为标题，然后在页脚中打印。我想添加一个像“1/3”的页码。

我希望这有助于您了解如何在dompdf中获取页眉和页脚。也请查看此链接.... Example

<html>
  <head>
   <style>
     @page { margin: 180px 50px; }
     #header { position: fixed; left: 0px; top: -180px; right: 0px; height: 150px; background-color: orange; text-align: center; }
     #footer { position: fixed; left: 0px; bottom: -180px; right: 0px; height: 150px; background-color: lightblue; }
     #footer .page:after { content: counter(page, upper-roman); }
   </style>
  <body>
   <div id="header">
     <h1>Widgets Express</h1>
   </div>
   <div id="footer">
     <p class="page">Page <?php $PAGE_NUM ?></p>
   </div>
   <div id="content">
     <p>the first page</p>
     <p style="page-break-before: always;">the second page</p>
   </div>
 </body>
 </html>

我还尝试将PHP代码添加到html中，但从来没有机会让它工作。这是我保证的完整内联代码：

require_once("dompdf_config.inc.php");
$html ='<html>
        <body>
        <p>Hello Hello</p><p style="page-break-after:always;page-break-before:always">Hello Hello 2</p><p>Hello Hello 3</p>
        </body>
        </html>';

$dompdf = new DOMPDF();
$dompdf->load_html($html);

$dompdf->render();

$canvas = $dompdf->get_canvas();
$font = Font_Metrics::get_font("helvetica", "bold");
$canvas->page_text(72, 18, "Header: {PAGE_NUM} of {PAGE_COUNT}", $font, 6, array(0,0,0));

$dompdf->stream("my_pdf.pdf", array("Attachment" => 0));
?>

<style>
        /** 
            Set the margins of the page to 0, so the footer and the header
            can be of the full height and width !

        @page {
            margin: 0cm 0cm;
        }
