Snappy & wkhtmltopdf：页脚中的页码

Question

我想在用 Snappy 和 Wkhtmltopdf 生成的每个页面的页脚中都有页码，但我没有找到任何关于它的线索。

我可以设置页脚文本（带有选项“footer-center”）但如何放置页码？

Answer 1

... 此处的文档表明某些标签已替换为例如页码。

Answer 2

将此添加为接受的答案只是一个 404 链接。

根据文档，Wkhtmltopdf 为我们提供了许多用于控制放置页脚文本的位置的选项：

  --footer-center <text>          Centered footer text
  --footer-font-name <name>       Set footer font name (default Arial)
  --footer-font-size <size>       Set footer font size (default 12)
  --footer-html <url>             Adds a html footer
  --footer-left <text>            Left aligned footer text
  --footer-line                   Display line above the footer
  --no-footer-line                Do not display line above the footer
                                  (default)
  --footer-right <text>           Right aligned footer text
  --footer-spacing <real>         Spacing between footer and content in mm
                                  (default 0)

在页脚（或页眉）中，您有许多关键字

* [page]       Replaced by the number of the pages currently being printed
* [frompage]   Replaced by the number of the first page to be printed
* [topage]     Replaced by the number of the last page to be printed
* [webpage]    Replaced by the URL of the page being printed
* [section]    Replaced by the name of the current section
* [subsection] Replaced by the name of the current subsection
* [date]       Replaced by the current date in system local format
* [isodate]    Replaced by the current date in ISO 8601 extended format
* [time]       Replaced by the current time in system local format
* [title]      Replaced by the title of the of the current page object
* [doctitle]   Replaced by the title of the output document
* [sitepage]   Replaced by the number of the page in the current site being converted
* [sitepages]  Replaced by the number of pages in the current site being converted

例如，为了在页脚右侧添加一个正在运行的页码，您可以在 KnpSnappy 中执行此操作：

$snappyPdf->setOption('footer-right', '[page]');
