adding a due by date to invoice adding 30 days

[foxnetwork]

I am trying to add to the invoice summary tab and extra position for due by date and add 30 days to the current date

I need this for invoice customers so they have thirty days. I have added files in invoice tpl file and it adds it to the invoice but with the current date. Bottom line.

<tr>
        <td class="center small white">{$title|escape:'html':'UTF-8'}</td>
        <td class="center small white">{dateFormat date=$order->invoice_date full=0}</td>
        <td class="center small white">{$order->getUniqReference()}</td>
        <td class="center small white">{dateFormat date=$order->date_add full=0}</td>
        <td class="center small white">{dateFormat date=$order->date_add full=0}</td>

Does anyone know where to change this so I can make the date appear 30 days later

 

I am using prestashop 8.1

 

Thanks for any help

Hello, how are you? You would need to create your own PHP function within the Tools class and access it from Smarty as you're currently doing, making the necessary changes to the function. If this relates to a module, you could extend the class and, in that way, avoid modifying the Tools class.

Hi.

You don't have to create any weird function, but just create an override of the HTMLInvoice.php file and the tpl template. It is easy. You use a php function and set your own variable in the TPL.

Thanks, buddy, but overrides are frowned upon by PrestaShop. Let's create cleaner code. Regards.
