Can't generate barcode in smarty

[Bruno]

Hi guys,

I made a customisation in prestashop 1.6.15, in delivery-slip.tpl to write a barcode with order id: 

{assign var=black value=[0,0,0]}{assign var=white value=[255,255,255]}
{assign var=stuff value=['position'=>'S', 'border'=>false, 'padding'=>3, 'fgcolor'=>$black, 'bgcolor'=>$white, 'text'=>true, 'font'=>'helvetica', 'fontsize'=>20, 'stretchtext'=>4]}
{assign var=params value=TCPDF::serializeTCPDFtagParameters(array("{$order->id}", 'C128', '', '', '0', 40, 0.4, $stuff, 'N'))}
 

<tcpdf method="write1DBarcode" params="{$barcode_params}" />

 

This doesn't work in TB 1.1.x (from github). First it crashes at TCPDF::serializeTCPDFtagParameters but if I move the function call in the controller it still doesn't run write1DBarcode.

This is a critical feature, needed to print carrier labels.

How can I fix it?

Class TCPDF doesn't contain static method serializeTCPDFtagParameters, there is only an instance method with the same name. You will need to instantiate the TCPDF object and run the method on it, ie:

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$barcodeParams = TCPDF::serializeTCPDFtagParameters([$order->id, 'C128', '', '', '0', 40, 0.4, $stuff, 'N']);

That was the first thing I did. Still, with $barcodeParams generated, this is not running: 

<tcpdf method="write1DBarcode" params="{$barcode_params}" />
