[Solved] Customizing PDF Invoice to Include Total Amount in Words

[Eutanasio]

Hi,

I'm trying to customize the PDF invoices generated by my Prestashop 1.7 store to include the total amount to be paid in words (in French), which is a legal requirement in my country. I've attempted to modify the following files but have not succeeded in getting the desired result. Here are the details of my approach:

1. Helper.php: Added a function to convert numbers to French words.

class Helper extends HelperCore
{
    public static function convert_number_to_words($num = false)
    {
        if (!is_numeric($num)) {
            return false;
        }

        $num = number_format($num, 2, '.', '');
        list($integerPart, $fractionPart) = explode('.', $num);

        $words = self::convert_integer_to_words_fr($integerPart);
        $currency = 'dirhams';
        $subunit = 'centimes';

        $words .= ' ' . $currency;

        if ($fractionPart > 0) {
            $words .= ' et ' . self::convert_integer_to_words_fr($fractionPart) . ' ' . $subunit;
        }

        return ucfirst(trim($words)) . '.';
    }

    private static function convert_integer_to_words_fr($num)
    {
        // Function implementation...
    }
}

2. invoice.note-tab.tpl: Modified the template to include the total amount in words.

{if isset($order_invoice->note) && $order_invoice->note}
    <tr>
        <td colspan="12" height="10">&nbsp;</td>
    </tr>

    <tr>
        <td colspan="6" class="left">
            <table id="note-tab" style="width: 100%">
                <tr>
                    <td class="grey">{l s='Note' d='Shop.Pdf' pdf='true'}</td>
                </tr>
                <tr>
                    <td class="note">{$order_invoice->note|nl2br} {$total_paid_in_words} Dirhams</td>
                </tr>
            </table>
        </td>
        <td colspan="1">&nbsp;</td>
    </tr>
{/if}

3. HTMLTemplateInvoice.php: Overridden the `getContent` method to assign the total amount in words to the template.

class HTMLTemplateInvoice extends HTMLTemplateInvoiceCore
{
    public function getContent()
    {
        $order = new Order((int)$this->order->id);
        $total_paid = $order->total_paid;

        // Convert total paid to words in French
        $total_paid_in_words = Helper::convert_number_to_words($total_paid);

        // Assign the total paid in words to the template
        $this->smarty->assign(array(
            'total_paid_in_words' => $total_paid_in_words,
        ));

        // Call the parent method to retain existing functionality
        return parent::getContent();
    }
}

Despite these modifications, the total amount in words does not appear on the PDF invoices. Could anyone guide me on what might be going wrong or provide a solution to achieve this customization?

Thank you in advance for your help!
