I'm able to generate a barcode by using the following code:
$code = '12345';
Then to generate the barcode, I do the following:
<barcode code="$code" type="C39" size="0.5" height="2.0" />
However, it is not generating the correct id. Is there something that I'm doing wrong? What I'm using is the mPDF tool, and I can't change to a different pdf tool.
Thank you..
