I am using Kartik mpdf library to generate pdf. I am generating barcode in the body of the pdf which contains mcqs question generated through loop so pages are inserted randomly depending on the questions, So I need the page number to be set in my barcode on each page.
Kartik mpdf provides a method 'SetFooter' => ['{PAGENO}|'] which gives page number in footer but this {'PAGENO'} is not working in my html document... How would I get the page number inside my document.
PAGENO has nothing to do with kartik, is from mpdf. When you say is not working in your html, that's because that placeholder variable is going to be parsed with mpdf, so if you are not generating a pdf it wont take effect.
On the other hand, you can't show the page number in your html. There's no pages numbers on a html document, as it will depend in the page size and the font size of the browser, so it won't be possible to know "where you are" on the server side.
