Replace html element to page number

[acgtwentyone]

Is it possible to use dompdf api to target a html element and then replace it by page number ? Let's say by using something like callbacks.

Ex: using something like this

$dompdf->setCallbacks(
    [
        [
            'event' => 'begin_frame',
            'f' => function ($frame) {
                $node = $frame->get_node();
                if ($node->nodeName === 'h1') {
                    $GLOBALS['SECTION'] = $node->textContent;
                }
            }
        ],
        [
            'event' => 'end_page_render',
            'f' => function ($frame, $canvas) use ($fontMetrics) {
                $text = $GLOBALS['SECTION'];
                $font = $fontMetrics->getFont('monospace');
                $pageWidth = $canvas->get_width();
                $pageHeight = $canvas->get_height();
                $size = 12;
                $width = $fontMetrics->getTextWidth($text, $font, $size);
                $canvas->text($pageWidth - $width - 20, $pageHeight - 20, $text, $font, $size);
            }
        ]
    ]
);
$dompdf->render();
$dompdf->stream();

As you can see in the picture, let's say i want to replace "#" by 1/5. So we get "Página 1/5".

Thank you @parallels999. If you can't help, don't say things you don't know.

[fredsal]

@parallels999 it happens a lot 😄

Thanks for each one of you. I should have search more.

You could do something like that, though if you're just inserting the standard page number for each page you can use generated content.

Thank you for pointing me out. I'll take a look.

@bsweeney I actually want to replace the text "#" to the current page number. Lets say 1/5 for example. So instead of "Pagina #" we get "Pagina 1/5". Is it possible to do using dompdf ?

Per the link, you can get the current page using just CSS. Or using script but why go through the trouble.

Unfortunately, the total number of pages is not available until the document is fully rendered. This is due to the way that Dompdf renders documents. Typically in that scenario we recommend writing the text as part of a page script.

It is possible to do string replacement after the document is fully rendered, though it's primarily a hack around current functionality. At any rate, I see @fredsal (thanks, buddy!) gave you some links that you were able to use to solve your issue.
