You need barcode fonts installed. I can only mention the M4 PDF Extensions module which can easily use many barcode fonts and there are already many examples in templates using barcodes.

PrestaShop uses the TCPDF library to generate PDF invoices. Barcodes are basically like other text but printed through a "barcode" font, not letters. That is all.

Hey,

 

im trying to show barcode at invoice footer but got this result: http://prntscr.com/6lwpfv

 

$barcodeobj = new TCPDFBarcode('http://www.myshop.eu' 'C128');

 

$barcod = $barcodeobj->getBarcodeHTML(2, 30, 'black');

 

and assign barcod to variables in HTMLTemplate.php getFooter function. What Did I do wrong? Thanks man!

Missing comma?

$barcodeobj = new TCPDFBarcode('http://www.myshop.eu', 'C128');

$barcodeobj = new TCPDFBarcode('http://www.myshop.eu', 'C128');

Sorry, using this:

 

$barcodeobj = new TCPDFBarcode("http://www.myshop.eu" , "C128");

 

$barcod = $barcodeobj->getBarcodeHTML(2, 30, "black");

 

But got same effect.

Sorry, I never used TCPDFBarcode class. I have simple <barcode> tags in my templates, but those don't use TCPDF library.

Mh, If I check the value with var_dump($barcod) I got correct bar code. And then add in footer {$barcod} I see only line like <hr />. So strange..

Hello,

 

I have same problem.

I try to include the generated HTML correctly; I think the tcpdf doesn't manage the "relative position".

 

Someone has another idea?

Hey, Ive changed my mind and using generated barcode in picture, but after all I commented a few lines maybe it helps u.

 

  $this->write1DBarcode('www.site.com', 'C39+', '', '', 20, 10, 0.4, $style, 'N');

 

It works , check write1DBarcode function details.

Hello, thank you for the reply

 

I am using a tpl template to generate pdf and using this code:

 

$pdf = new PDF($this->boxes, PDF::TEMPLATE_AIRWAY,Context::getContext()->smarty);

$pdf->render(true);

 

This is how i generate barcode:

 

$tcpdfbarcode = new TCPDFBarcode($order->getUniqReference(), EAN13);

$bar = $tcpdfbarcode->getBarcodePNG(2, 30, array(0,0,0) );

 

and i assign the $bar to smarty data so i can print them in tpl template.

 

Can you tell me how can i add this to smarty ?

 

Thank you

This is how I added barcodes to templates, with no need to change any php code. 

 

For yours, $bar has a png image in it.  You might be able to do something like

 

$smarty->assign('bar', base64_encode($bar));

 

then in the template

 

<img src="data:image/png;base64,{$bar}" alt="barcode">

 

But I haven't tested that at all!
