Barcode insertion code does not work in 1.7 which was working in 1.6

Presta Roshan · January 28, 2018

Hi everyone,

Hope you guys are enjoying a good weekend...

But for me having this issue kills my mood

I'v been working on a module to upgrade to support from 1.6 to 1.7 Prestashop version.

This module which was working fine and generates proper bar codes in PDF for admin tasks.

( I implemented exactly as its described like in this thread to print bar codes in my PDF)

But since when I upgraded and while testing I found out that the Smarty template code below does not produce the bar code which used to work fine in 1.6.

I have no other problems while upgrading it. only this is the issue.

I'm not sure if this is because of a bug or perhaps implementation of bar code in 1.7 has been changed..

Can anyone guide me to fix this issue?

Thanks in advance..

In my controller this is how I prepare serialized bar code string

// Initiat PDF class

$pdf = new PDFGenerator((bool)Configuration::get('PS_PDF_USE_CACHE'));

// Prepare barcode

$barcode_params = $pdf->serializeTCPDFtagParameters(array(

'123456789',

'C39',

'',

50,

20,

0.2,

array(

'position'=>'S',

'border'=>false,

'padding'=>0,

'fgcolor'=>array(0,0,0),

'bgcolor'=>array(255,255,255),

'text'=>true,

'font'=>'Helvetica',

'fontsize'=>8,

'stretchtext'=>0),

'N'));

And in my Smarty template

<tr>
<td>
<b>Shipper Order Number:</b>

</td>
<td >
<tcpdf method="write1DBarcode" params="{$order.other_data.awb_barcode}" />
</td>
</tr>

Guys, any suggestions please???

Ok, I resolved this issue myself.

But not with this method. for some reason '<tcpd method="write1DBarcode" ... ' seems does not work.

So what I did was I bypassed 'HTMLTemplate..' class creation and smarty templates all together for labels and instead used a normal method to output a PDF custom HTML label using native function of TCPD class.

so here is the codes I used for producing the PDF label.

$style = array(

'position' => 'C',

'align' => 'C',

'stretch' => false,

'fitwidth' => true,

'cellfitalign' => '',

'border' => true,

'hpadding' => 'auto',

'vpadding' => 'auto',

'fgcolor' => array(0,0,0),

'bgcolor' => array(255,255,255),

'text' => true,

'font' => 'helvetica',

'fontsize' => 8,

'stretchtext' => 4

);

$html = '<html><head><title></title><style>table { border-collapse: collapse;font-family:arial;}td {padding: 10px; vertical-align: center;}';

$html .= '</style></head><body>';

foreach ($orders_array as $order)

{

$html = $this->prepare_html_label($order); // this is where my html template is prepared with actual values

$pdf->setXY(93,472);

$pdf->Ln(5);

$pdf->write1DBarcode('*'.$order['awb'].'*', 'C128', '', '', '', 18, 0.4, $style, 'N');

$pdf->Ln(10);

$pdf->writeHTML($html, true, false, true, false, '');

}

$pdf->Output('labels.pdf', 'D');

}

Problem solved.!

Hope this helps some one.

Can you explain in which files and line code you added this?

please, I'm also interested.

I'm interested too, where did you add that code.

SOLVED - Hello guys , i've been searching many times and tried to use TCPDFBarcode module i wrote the code as mentioned in the TCPDF Documentation but did not work

i got an idea, which is to convert text to barcode using only html and css, i found it using a font family, and tried many times to include it in prestashop and finally found a solution ,

TCPDF can't recognize new fonts we have to convert it to its supported formats, so follow those steps :

A : Generate font by CLI (if there is a command line interface in your server otherwise read A steps and go to B steps)

1 - download woff2 file from : https://fonts.gstatic.com/s/librebarcode39/v19/-nFnOHM08vwC6h8Li1eQnP_AHzI2G_Bx0g.woff2
2 - convert it to .ttf format using this link : https://cloudconvert.com/woff2-to-ttf
3 - put .ttf file to this path \vendor\tecnickcom\tcpdf\tools (optionally: rename it because you will use that name as font-family name, Ex : barcodefont)
4 - use this command line to convert/add font by TCPDF : php tcpdf_addfont.php -i barcodefont.ttf (php required in your local host if you use B steps)
then 3 files will be generating to this path : \vendor\tecnickcom\tcpdf\fonts including font name

barcodefont.php
barcodefont.ctg.z

barcodefont.z

B : convert font to TCPDF formats using your local machine

1 - install prestashop to your local host using xampp with compatible php version to prestashop 1.7 (xampp V3.3.0) Google that if you are not familiar with local host server
2 - after doing A steps , put those 3 files to \vendor\tecnickcom\tcpdf\fonts in your server
3 - use this in *.tpl file : <p style="font-family: 'barcodefont';font-size: 30px;text-align:center">*{$YOUR_VAR} or your text*</p>
NOTE : * is required before and after text, it's an encode technique of 'C39 type'

if you want to include some variables in invoice.tpl follow those steps:

1 - go to classes/pdf/HTMLTemplateInvoice.php

2 - search for getContent function

3 - and add your variables before Data array ($data) Ex :

$phone_mobile= $invoice_address->phone_mobile;
$phone= $invoice_address->phone;
$nb_orders = count(Order::getCustomerOrders((int)$this->order->id_customer)); // this is total orders of a client

4 - then add them below to Data array :

'phone_mobile' => $phone_mobile,
'phone' => $phone,
'nb_orders' => $nb_orders,

5 - then insert your variable to invoice.tpl like this : {$phone_mobile)

if you want to convert it to barcode use this :

<p style="font-family: 'barcodefont';font-size: 30px;text-align:center">*{$phone_mobile}*</p> // do not forget * before and after variable

DONE, if you find this useful share it ^^

You are amazing! this totally worked thank you so much!!!

I was stuck at the "run php command" part for a while since my server is not very easy to use and I am new to prestashop 1.7

However, in case this can help anybody, I used this site: https://fonts.palettize.me/ to obtain the .php, .ctg.z and .z files and then it worked perfectlly.

currently using: prestashop 1.7.6.8

Barcode insertion code does not work in 1.7 which was working in 1.6
