Pdf Files

One of the interaction with the Customers involve sending mails, including pdf files.

For example, for every order you do on a Shop as a Customer we expect to receive an Invoice.

Working on what make a shop an unique experience, as a Developer you will be asked to customize every PDF files that PrestaShop can produce.

You can alter the rendering using the provided data or push the PDF Rendering to its best, introducing your very own information that will made your PDF files amazing.

Customize the PDF files templates

All PDF generated by PrestaShop are using Smarty templates and TCPDF as PDF rendering engine.

You will find all theses templates in the pdf folder, for each use case managed natively by the Core.

You can alter the Core files OR override them by copying them on themes/<your-theme>/pdf folder.

It’s not possible to override a PDF template in a module.

Alter or Add information available into PDF templates

A dynamic hook allows you to alter or add more information that will become available in the previous templates.

There is the list of available Template Classes in the Core:

  • HTMLTemplateDeliverySlip
  • HTMLTemplateInvoice
  • HTMLTemplateOrderReturn
  • HTMLTemplateOrderSlip
  • HTMLTemplateSupplyOrderForm

If your shop is available for the European Union, the GDPR module must be installed.

This means you can generate another PDF thanks to the class named HTMLTemplatePSGDPRModule. This PDF will contain all the Customer Information.

To guess the hook for each template, we can look at the HTMLTemplate abstract Class:

<?php
// l. 160
$template = ucfirst(str_replace('HTMLTemplate', '', get_class($this)));
$hook_name = 'displayPDF' . $template;

List of available Hooks

Concept Hook name
Invoice displayPDFInvoice
Invoice displayInvoiceLegalFreeText
Delivery Slip displayPDFDeliverySlip
Order Return displayPDFOrderReturn
Order Slip displayPDFOrderSlip
Supply Order displayPDFSupplyOrderForm
GDPR Archive displayPDFPSGDPRModule

Minimal Example: add an extra property to the Invoice

In modules/your-module/your-module.php:

<?php
public function hookDisplayPDFInvoice($hookArgs)
{
    $customer = $this->context->customer;
    $hookArgs['object']->is_birthday = $this->isBirthday($customer->birthday);
}

// Naive implementation: don't do that.
private function isBirthDay(string $customerBirthday)
{
    return date('y-m-d') == $customerBirthday;
}

In themes/your-theme/pdf/invoice.note-tab.tpl:

{* ... keep the content ... *}
{if $order_invoice->is_birthday}
    <tr>
        <td colspan="12">
            {l s='Happy Birthday !' d='Modules.YourModule.Pdf' pdf='true'}
        </td>
    </tr>
{/if}

You will get an Invoice would look like this:

Variables

For each of these templates, Smarty variables are available.

There is the list of the variables available:

  • {lastname}
  • {firstname}
  • {id_order}

  • {delivery_block_txt}
  • {invoice_block_txt}

This is also the right place to dump them and figure out what they provide.

Add or alter Smarty variables

As always, you can hook into this email workflow and while there are multiples hooks that can fit this specific needs, the best one is named actionGetExtraMailTemplateVars.

Once you get the right hook, you will be able to alter or add extra variables:

<?php
// your-module/your-module.php

public function install()
{
    ...
    $this->registerHook('actionGetExtraMailTemplateVars');
}

public function hookActionGetExtraMailTemplateVars($hookArgs)
{
    dump($hookArgs);
    // Adapted from PrestaShop Email Manager Module
    $hookArgs['extra_template_vars']['{password}'] = '*******'; 
}
