Hello. 

I am generating my DOCX files from HTML. I need to be able to set different Headers and Footers for the pages. I found the solution by creating an array of pages merging them in the end. It doesn't work for me. In my case, the first page is not always a Title page and it not necessarily has the same amount of text. As a result, I can't separate the first page from the rest of the content. Also, there could be a situation when I need to set an original header somewhere in the middle of a document, let's say knowing only the page number.

In which way I can achieve that?

Hello,

Before answering your question, it's important to understand that DOCX documents don't work with pages but sections. Each section can fill one or more pages (even less than one page using continuous sections) and they may contain or not headers/footers. The number of pages and the position of the contents in a DOCX may vary based on the DOCX reader and its compatibility with the OOXML standard.

phpdocx allows working with headers and footers in the same way than MS Word (also compatible with LibreOffice, Google Docs and other DOCX readers):

· Setting first, default and even values that set the different available values to set headers and footers in a section: addHeader, addFooter. This is also compatible with HTML Extended.

· Adding more than one section with heders/footers. To accomplish this task, DOCX documents must be generated as standalone documents (one for each section with headers/footers) and then merge using mergeDocx. This approach is explained on https://www.phpdocx.com/documentation/cookbook/headers-and-footers-for-sections

To be able to change headers and footers, since phpdocx 9.5, DOCXPath includes support for headers and footers. But to be able to change them, these contents must exist in the DOCX (empty or with contents), so you can query them and add/change/remove contents based on the section. There's no the method to get content knowing the page number.

There's no alternative way to work with headers/footers when working with phpdocx. You need to use sections as MS Word does.

Regards.
