getting a page footer in a pdf?

[jamie]

i have finally got it working. Should anyone else need to enable it, here is how i did it first in vendor/dompdf/dompdf/src/Options.php set

private $isPhpEnabled = true; 

Then, create a template helper with the following code

<?php
namespace Espo\Custom\TemplateHelpers;
use Espo\Core\Htmlizer\Helper;
use Espo\Core\Htmlizer\Helper\Data;
use Espo\Core\Htmlizer\Helper\Result;
class pdfPageNumbers implements Helper
{
public function __construct() {}
public function render(Data $data): Result
{
$html = '
<div class="footer" style="position: fixed; bottom: 10px; width: 100%; text-align: right; font-size: 6px;">
<script type="text/php">
if (isset($pdf)) {
// Set position on page (x = right margin, y = distance from top)
$x = 560;
$y = 825;
$text = "{PAGE_NUM} / {PAGE_COUNT}";
$font = $fontMetrics->get_font("Open Sans", "normal");
// Render page numbers on every page
$pdf->page_text($x, $y, $text, $font, 6, [0,0,0], null, "right");
}
</script>
</div>
';
return Result::createSafeString($html);
}
}

i don't think the $font does anything

Footer class is set in my stylesheet

.footer {
position: fixed;
bottom: 0;
left: 0;
right: 0;
padding: 0.2em 2em;
font-size: 8px;
display: flex;
justify-content: space-between;
align-items: center;
background-color: #ececec;
color: #000;
z-index: -1;
}

Warning. Read the comment below.

Warning to whomever read. This solution introduces a critical security vulnerability to your system. Anyone with edit access to templates can do whatever they want with the system, including extracting confidential data.

I tested conditional logic in the footer. It works for me on multiple pages.

<div style="width: 100%; text-align: center;">
  <span>{pageNumber}&nbsp;</span>
  <span x-if="{{equal type 'Invoice'}}">Invoice</span>
  <span x-if="{{equal type 'Debit Note'}}">Debit Note</span>
</div>

So Dompdf already supports total number of pages?

[yuri]

This topic was about dynamic footer. I see there's no any issues with dynamic footers. The claims that it's extremely difficult turned out not to be confirmed.

[jamie]

i dont' see where your showing the total number of pages? Did you have to enable anything to get the x-if working? That would be very useful in the future

> I couldn't use variables in it either

What are variables? Placeholders? They work fine for me. Placeholders are printed in the footer on the second page.

for example {{cCompany.footer}} i tried that and it didn't work i think i've got to stick with template helpers for now, as I finally have page numbers working

Here is the discussion about it: https://github.com/dompdf/dompdf/iss...ment-740015376

Not sure if the workaround still works or how to use it.

There are not many free PHP PDF libaries around.TCPDF is in maintance mode and has only a few new commits. There is a successor available called tc-lib-pdf.
But it has only a stable release recently. It's still work in progress and I don't know if its on par with tcpdf yet and what are the advantages or disadvantages of the new version.

makes you wish darn adobe would make one, though i won't hold my breath for that. if you see the second page i did finnally get it all working with dompdf and detailed how i did it
