如何获得 wkhtmltopdf 正文中的总页数? [英] How do I get total pages in wkhtmltopdf body?
问题描述
是否可以访问主要内容正文中的topage"变量?
Is it possible to access the "topage" variable within the main content body?
我知道您可以在页眉和页脚中执行此操作，但在此特定用例中，我需要在正文中放置一个句子:
I know you can do it in headers and footers but in this specific use case, I need to put a sentence within the body that says:
此文档包含 XX 页".
"This document contains XX pages".
推荐答案
这对我有用.但需要在页眉(ou页脚)在正文中，我认为这是不可能的，就像他们在 GitHub 中所说的那样http://github.com/wkhtmltopdf/wkhtmltopdf/issues/1889
This works to me. But need to be in the header (ou footer) In the body I think it is not possible, like they said in the GitHub http://github.com/wkhtmltopdf/wkhtmltopdf/issues/1889
要将此信息放在页脚中，您可以在此链接中看到@Unixmonkey:https://github.com/mileszs/wicked_pdf#page-numbering
