提问by Pedro
For example Page 1 of 5.
例如Page 1 of 5。
There's an example onlineof how to get teh Page 1part but not the of 5part. This is it:
网上有一个示例，说明如何获取Page 1零件而不是of 5零件。就是这个：
.pagenum:before { content: "Page " counter(page); }
I'm using version 0.6 and $PAGE_NUMand $PAGE_COUNTdoes not work.
我使用的是0.6版本，并$PAGE_NUM与$PAGE_COUNT不工作。

By default, inline PHP is disabled for security reasons, you need to enable it yourself in dompdf_config.custom.inc.php. See here.
默认情况下，出于安全原因禁用内联 PHP，您需要在 dompdf_config.custom.inc.php 中自行启用它。见这里。
For now, total page count is not supported with the CSS you are using, we are planning to make it work in 0.6 final though.
目前，您使用的 CSS 不支持总页数，但我们计划使其在 0.6 final 中工作。

For people coming here using a new version of DomPdf
对于使用新版本 DomPdf 来到这里的人们
Since
dompdf0.7.0, thedompdf_config.inc.phpfile has been removed (and is no longer referenced): all dompdf options should be set at run time.
自 以来，该文件已被删除（不再引用）：所有 dompdf 选项都应在运行时设置。
dompdf0.7.0dompdf_config.inc.php
This means you have to create a new instance of Optionsclass
这意味着您必须创建一个新的Options类实例
$domPdfOptions = new Options();
And then you may enable PHP inline using the following line
然后您可以使用以下行启用内联 PHP
$domPdfOptions->set("isPhpEnabled", true);
The rest of the codes are correct and will show a page number and page count
其余代码正确，将显示页码和页数
<script type="text/php">
if (isset($pdf))
{
$x = 72;
$y = 18;
$text = "{PAGE_NUM} of {PAGE_COUNT}";
$font = $fontMetrics->get_font("helvetica", "bold");
$size = 6;
$color = array(255,0,0);
$word_space = 0.0; // default
$char_space = 0.0; // default
$angle = 0.0; // default
$pdf->page_text($x, $y, $text, $font, $size, $color, $word_space, $char_space, $angle);
}
</script>
UpdateAs pointed out by @london-smith, this also works for DomPDF 0.8.1
更新正如@london-smith 所指出的，这也适用于 DomPDF 0.8.1

Check you have enabled inline_pdf in dompdf.
检查您是否在 dompdf 中启用了 inline_pdf。
Use this code, you can put where you like, it gets the height and width of the document and puts the page/total_pages at the bottom right.
使用这段代码，你可以把它放在你喜欢的地方，它获取文档的高度和宽度并将page/total_pages放在右下角。
<script type = "text/php">
if ( isset($pdf) ) {
$pdf->page_script('
if ($PAGE_COUNT > 1) {
$font = Font_Metrics::get_font("Arial, Helvetica, sans-serif", "normal");
$size = 12;
$pageText = $PAGE_NUM . "/" . $PAGE_COUNT;
$y = $pdf->get_height() - 24;
$x = $pdf->get_width() - 15 - Font_Metrics::get_text_width($pageText, $font, $size);
$pdf->text($x, $y, $pageText, $font, $size);
}
');
}

I dont know which kind of content you want to render. I got a bunch of pictures and a maximal Pictures per Site constant.
我不知道您要呈现哪种内容。我得到了一堆图片和每个站点常量的最大图片。
So a function gives me the site number (total/max) and then I got everything I need to start creating the pdf.
因此，一个函数为我提供了站点编号（总数/最大值），然后我得到了开始创建 pdf 所需的一切。
@for ($i = 1;$i <= $pages; $i++)
@if ($i !== 1)
<div style="page-break-before: always;"></div>
@endif
#Code for each Site
@end
Thats how I seperate my Sites and their I also got $pages as a blade variable.
这就是我如何分离我的站点和他们的我也将 $pages 作为刀片变量。
<div class="info_footer">
Page <span class="pagenum"></span> / {{$pages}}
</div>
With Stylesheet:
使用样式表：
.pagenum:before { content: counter(page); }

$PAGE_COUNTis the total number of pages.

}
</script>

If you are using an old version where this is not supported, upgrade. Otherwise, you may be out of luck.
如果您使用的是不受支持的旧版本，请升级。否则，您可能会倒霉。

In php, you can access dompdf variables:
在 php 中，您可以访问 dompdf 变量：
$PAGE_NUM the current page number
$PAGE_COUNT the total number of pages in the document
回答by Dustin Butler
See the attachment named issue121.php on this bug report. Worked for me. As I understand it you can't echo the page num but you can draw it somewhere.
请参阅此错误报告中名为 issue121.php 的附件。为我工作。据我了解，您无法回显页面编号，但您可以将其绘制在某处。
