dompdf为页面编号，但跳过第一个

标签： php dompdf

我使用dompdf类，并且我需要为每个页面进行页面numembering

我做到了，而且有效：

$dompdf = new Dompdf();
$dompdf->load_html($html);
$dompdf->render();

$canvas = $dompdf->get_canvas();
$font = $dompdf->getFontMetrics()->get_font("helvetica", "bold");

$canvas->page_text(72, 18, "Header: {PAGE_NUM}", $font, 6, array(0,0,0));

我需要的只是跳过第一页，然后从第二页开始编号。

我该怎么做？

这对我有用：

$dompdf = new Dompdf();
$dompdf->load_html($html);
$dompdf->render();

$canvas = $dompdf->get_canvas();
$cpdf = $canvas->get_cpdf();

$font = $dompdf->getFontMetrics()->get_font("helvetica", "bold");

$firstPageId = $cpdf->getFirstPageId();
$objects = $cpdf->objects;
$pages = array_filter($objects, function($v) {
    return $v['t'] == 'page';
});
$number = 1;
foreach($pages as $pageId => $page) {
    if(($pageId + 1) !== $firstPageId) {
        $canvas->reopen_object($pageId + 1);
        $canvas->text(72, 18, "Header: $number", $font, 6, array(0,0,0));
        $canvas->close_object();
        $number++;
    }
}

$dompdf->stream();

这是如何工作的：

  1. 从https://github.com/dompdf/dompdf/blob/v0.8.2/lib/Cpdf.php#L32
    2. 获取所有页面
  2. 将文本添加到第一页以外的所有页面。

在dompdf 0.6.2或更早版本中尝试以下操作：

$dompdf->render();
$canvas = $dompdf->get_canvas();
$canvas->page_script('
  if ($PAGE_NUM > 1) {
    $font = Font_Metrics::get_font("helvetica", "bold");
    $current_page = $PAGE_NUM-1;
    $total_pages = $PAGE_COUNT-1;
    $pdf->text(522, 770, "Page: $current_page of $total_pages", $font, 10, array(0,0,0));
  }
');

从dompdf 0.7.0开始，情况有所不同：

$dompdf->render();
$canvas = $dompdf->getCanvas();
$canvas->page_script('
  if ($PAGE_NUM > 1) {
    $font = $fontMetrics->getFont("helvetica", "bold");
    $current_page = $PAGE_NUM-1;
    $total_pages = $PAGE_COUNT-1;
    $pdf->text(522, 770, "Page: $current_page of $total_pages", $font, 10, array(0,0,0));
  }
');

以前没有使用过DOMPDF，但是在此GitHub DOMPDF Post中遇到了一个纯CSS解决方案，并准备了一个小例子，也许您会发现它很有用。

body {
  counter-reset: page;
}

.footer:not(:first-child) .page-number:before {
  counter-increment: page;
  color: red;
  content: 'Page ';
}

.footer:not(:first-child) .page-number:after {
  color: red;
  content: counter(page);
}

来自this link 您可以使用以下功能

// set page number on the left side
$pdf->page_text(16, $y, "Page: {PAGE_NUM} of {PAGE_COUNT}", $font, 8, $color);
