I have this function generating files from html files and I can't seem to get a dynamic footer with page count to generate -> I need to be able to do this on the backend with Go/HTML so the javascript solutions don't work for me
Here's my code
{{define "Count"}}Invoice Footer{{end}}
{{define "invoiceFooter"}}
<foot>
<script>
var pdfInfo = {};
var x = document.location.search.substring(1).split('&');
for (var i in x) { var z = x[i].split('=',2); pdfInfo[z[0]] = unescape(z[1]); }
function getPdfInfo() {
var page = pdfInfo.page || 1;
var pageCount = pdfInfo.topage || 1;
document.getElementsByClassName('page').textContent = page;
document.getElementsByClassName('topage').textContent = pageCount;
}
</script>
</foot>
<body style="border:0; margin: 0;" onload="getPdfInfo()">
<table style="border-bottom: 1px solid black; width: 100%">
<tr>
<td class="--footer-center"></td>
<td style="text-align:center">
Page <span class="page"></span> of <span class="topage"></span>
</td>
</tr>
</table>
{{end}}
func generatePDF(data *cs.FileData) (pdfgBytes []byte, err error) {
var templ *template.Template
_, err = os.Getwd()
if err != nil {
return nil, err
}
tmplFiles, err := fs.ReadDir(templateDir, "templates")
if err != nil {
return nil, err
}
files := []string{}
for _, file := range tmplFiles {
if file.IsDir() {
continue
}
files = append(files, fmt.Sprintf("templates/%s", file.Name()))
}
// use Go's default HTML template generation tools to generate your HTML
if templ = template.Must(template.ParseFS(templateDir, files...)); err != nil {
return
}
// apply the parsed HTML template data and keep the result in a Buffer
var body bytes.Buffer
if err = templ.Execute(&body, data); err != nil {
return
}
// Create new PDF generator
pdfg, err := pdf.NewPDFGenerator()
if err != nil {
return
}
// read the HTML page as a PDF page
page := pdf.NewPageReader(bytes.NewReader(body.Bytes()))
// enable this if the HTML file contains local references such as images, CSS, etc.
page.EnableLocalFileAccess.Set(true)
//page := NewPage(`D:\body.html`)
page.FooterHTML.Set(`--footer-html`)
page.FooterCenter.Set("test")
page.FooterFontSize.Set(7)
//page.FooterRight.Set("[page]")
// add the page to your generator
pdfg.AddPage(page)
I've tried variations of all of these:
