MPDF page number in HTML

[ghost]

Hello,

Currently I'm creating a template system, and we are using MPDF to generate the PDF versions of the templates, so far this has been great. But the only problem that we are having is that the page numbering tags do not get replaced in the WriteHTML block, but this is something that we would like to have. Is it in any way possible to get this working with a setting that I have missed?

The Issue template is not here for nothing. Provide a minimal, complete, and verifiable example for your usecase, including your setup and library versions.

I assume some reproduction code as following

<?php

require_once __DIR__ . '/vendor/autoload.php';

$mpdf = new \Mpdf\Mpdf();
$mpdf->WriteHTML('Page {PAGENO} of {nb}');
$mpdf->Output();
?>

Current output:

Page {PAGENO} of {nb}

Requested output:

Page 1 of 1

Solved with MPDF 6.1 as following

Changed function _puthtmlheaders() in mpdf.php: Added code block "Replace page no and total pages number variables in body of every page"

                                }
                                /* -- FORMS -- */
                                foreach ($this->HTMLheaderPageForms AS $f) {
                                        $f['y'] += $adj;
                                        $this->mpdfform->forms[$f['n']] = $f;
                                }
                                /* -- END FORMS -- */
                        }

                        // Replace page no and total pages number variables in body of every page
                        $this->pages[$n] = str_replace(mb_convert_encoding('{PAGENO}', 'UTF-16', 'UTF-8'), mb_convert_encoding($pnstr, 'UTF-16', 'UTF-8'), $this->pages[$n]);
                        $this->pages[$n] = str_replace(mb_convert_encoding($this->aliasNbPgGp, 'UTF-16', 'UTF-8'), mb_convert_encoding($pntstr, 'UTF-16', 'UTF-8'), $this->pages[$n]); // {nbpg}
                        $this->pages[$n] = str_replace(mb_convert_encoding($this->aliasNbPg, 'UTF-16', 'UTF-8'), mb_convert_encoding($nb, 'UTF-16', 'UTF-8'), $this->pages[$n]); // {nb}

                }
                $this->page = $nb;
                $this->state = 1;
        }

This is intended and documented behaviour. Page patterns are being replaced in headers and footers only.

[jochenwezel]

The requested behavious is (at least from my side) to support it in body, too.
An "intendation" that this must not happen in body wouldn't be understandable.

I'd also like to have the feature as proposed by @jochenwezel.

@finwe Should I open a PR with the above mentioned solution, or is there a serious blocker over here (based on the help wanted label)?

[davidvanvan]

any update on this possible feature? I am actually using his sulotion, with version 8.0, and it is working

Have you created a PR good sir? I think this feature proposed by @jochenwezel is great

I solved it in my environment in mpdf.php in function _puthtmlheaders() with following code (approx. line 9728). If somebody could review it (especially for right version) and create a patch for for this ticket, I'd appreciate it :-)

Since Mpdf.php of v7 has been redesigned completely, I can’t quickly find the missing piece. I solved it by stepping through the code with some debugging and finally found a code location to fix it.
