Add support for header and footer with some tags available

[artnum]

Header and footer for printing can be set via new setHeaderFooter function. It allows to specify tags like filename, path, date, time, page number, pages count and tab name. Tested with Office 360.

Hello,

can not find the function "setHeaderFooter" in the currently file xlsxwriter.class.php. Was it removed again?

Thanks

Hello,

I found everything and it works so far. How can I write a different header for each sheet?

public function setHeaderFooter($sheet_name, $pos, $content, $footer = false) ?

thanks

It would be possible to set different header/footer for odd and even sheet as far as I know.
