Add customer VAT on PrestaShop invoices

Si nous voulons afficher la TVA du client sur les factures PrestaShop comme dans l'image suivante, nous n'avons qu'à modifier 2 fichiers.

Le premier fichier à modifier sera pdf/invoice.address-tab.tpl où nous ajouterons cette ligne qui indiquera la TVA du client :

{if $vat}TVA : {$vat}{/if}

Laissant le fichier comme ceci :

<table id="addresses-tab" cellspacing="0" cellpadding="0">

<tr>

<td width="50%">{if $delivery_address}{l s='Delivery Address' d='Shop.Pdf' pdf='true'} 

{$delivery_address}

{/if}

</td>

<td width="50%">{l s='Billing Address' d='Shop.Pdf' pdf='true'} 

{$invoice_address} 

{if $vat}VAT: {$vat}{/if}

</td>

</tr>

</table>

L'autre fichier à modifier est le classes/pdf/HTMLTemplateInvoice.php, mais nous allons créer un override du fichier en le créant dans overrides/classes/HTMLTemplateInvoice.php

La ligne que nous ajouterons sera celle-ci

'vat' => ($invoice_address->vat_number != null ? $invoice_address->vat_number : $delivery_address->vat_number),

Et le fichier ressemblerait à ceci :

<?php
