Unable to set header and footer with template

[darylhjd]

Using this code:

func main() {
	pdf := fpdf.New(fpdf.OrientationPortrait, fpdf.UnitMillimeter, fpdf.PageSizeA4, "")
	pdf.SetFont("Arial", "", 13)

	contentPageTemplate := pdf.CreateTemplate(func(tpl *fpdf.Tpl) {
		tpl.SetHeaderFuncMode(func() {
			tpl.SetY(5)
			tpl.SetFont("Arial", "B", 15)
			tpl.Cell(80, 0, "")
			tpl.CellFormat(30, 10, "Title", "1", 0, "C", false, 0, "")
			tpl.Ln(20)
			tpl.CellFormat(30, 10, "Class Report", "", 0, fpdf.AlignCenter, false, 0, "")
		}, true)
		tpl.SetFooterFunc(func() {
			tpl.SetY(-15)
			tpl.SetFont("Arial", "I", 13)
			tpl.CellFormat(0, 10, fmt.Sprintf("Page %d/{nb}", tpl.PageNo()),
				"", 0, "C", false, 0, "")
		})
	})

	pdf.AliasNbPages("")
	pdf.AddPage()
	pdf.CellFormat(0, 10, "This is the front cover", "", 0, fpdf.AlignCenter, false, 0, "")
	pdf.AddPage()
	pdf.UseTemplate(contentPageTemplate)
	pdf.CellFormat(0, 10, "This is the a content page with header and footer", "", 0, fpdf.AlignCenter, false, 0, "")

	log.Println(pdf.PageCount())

	pdf.OutputFileAndClose("test.pdf")
}

I am not able to add a header and footer on the second page. Is this the wrong way to do it?

Also, I am not sure if the authors of fpdf are open to using the Discussions page for this repo. I was looking for it to ask the question but it seems it is only possible for me to do so via opening an issue.

Thanks!
