pdf height

Hello @rokeyfx,

Please add this code snippet to your site to set the PDF height of the content:

add_filter( 'wpo_wcpdf_before_dompdf_render', function( $_dompdf, $html )
{
	$_dompdf_options           = $_dompdf->getOptions();
	$_dompdf_paper_size        = $_dompdf->getPaperSize();
	$_dompdf_paper_orientation = $_dompdf->getPaperOrientation();

	$GLOBALS['wpo_wcpdf_dompdf_body_height'] = 0;
	$_dompdf->setCallbacks(
		array(
			'myCallbacks' => array(
				'event' => 'end_frame',
				'f'     => function ( $infos ) {
					$frame = $infos["frame"];
					if ( strtolower( $frame->get_node()->nodeName ) === "body" ) {
						$padding_box                              = $frame->get_padding_box();
						$GLOBALS['wpo_wcpdf_dompdf_body_height'] += $padding_box['h'];
					}
				},
			)
		)
	);

	$_dompdf->loadHtml( $html );
	$_dompdf->render();
	unset( $_dompdf );

	if( ! empty( $_dompdf_paper_size  ) ) {
		$_dompdf_paper_size[3] = $GLOBALS['wpo_wcpdf_dompdf_body_height'] + 150;
	}

	$dompdf = new \Dompdf\Dompdf( $_dompdf_options );
	$dompdf->loadHtml( $html );
	$dompdf->setPaper( $_dompdf_paper_size, $_dompdf_paper_orientation );

	return $dompdf;
}, 10, 2 );

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters

Let me know if it works!

it work with auto height. but now how i set width 80mm fixed?

Hello @rokeyfx,

I can provide you another code snippet to set the width to 80mm, but it will require several CSS rules to fit your invoice elements to the right place and size.

My recommendation is to use Premium Templates since this extension includes a customizer that allows you to tailor your PDF documents using product columns, total rows, and custom blocks.

However, here is the code for you:

add_filter( 'wpo_wcpdf_paper_format', function( $paper_format, $document_type) {
	// change the values below
    $width = 80; //mm!
    $height = 115; //mm!
 
    //convert mm to points
    $paper_format = array( 0, 0, ($width/25.4) * 72, ($height/25.4) * 72 );
 
    return $paper_format;
}, 10, 2 );

add_filter( 'wpo_wcpdf_before_dompdf_render', function( $_dompdf, $html )
{
	$_dompdf_options           = $_dompdf->getOptions();
	$_dompdf_paper_size        = $_dompdf->getPaperSize();
	$_dompdf_paper_orientation = $_dompdf->getPaperOrientation();

	$GLOBALS['wpo_wcpdf_dompdf_body_height'] = 0;
	$_dompdf->setCallbacks(
		array(
			'myCallbacks' => array(
				'event' => 'end_frame',
				'f'     => function ( $infos ) {
					$frame = $infos["frame"];
					if ( strtolower( $frame->get_node()->nodeName ) === "body" ) {
						$padding_box                              = $frame->get_padding_box();
						$GLOBALS['wpo_wcpdf_dompdf_body_height'] += $padding_box['h'];
					}
				},
			)
		)
	);

	$_dompdf->loadHtml( $html );
	$_dompdf->render();
	unset( $_dompdf );

	if( ! empty( $_dompdf_paper_size  ) ) {
		$_dompdf_paper_size[3] = $GLOBALS['wpo_wcpdf_dompdf_body_height'] + 150; // if too many space at the bottom, replace this 150 value with a lower one
	}

	$dompdf = new \Dompdf\Dompdf( $_dompdf_options );
	$dompdf->loadHtml( $html );
	$dompdf->setPaper( $_dompdf_paper_size, $_dompdf_paper_orientation );

	return $dompdf;
}, 10, 2 );

Thank you.

Hi another request.
is there anyway disable page break?
so it make very long pdf.

Hello @rokeyfx,

Use the code that I left you above to get a unique sheet of 80?mm width per order, special for continuous feed printers.
