[Prestashop development] Edit, Modify a PDF file in Prestashop?

Step 1: find a Entry PHP Class file that executed to generate your PDF file.

• invoice** tpl: Entry PHP class is PRETSASHOP_ROOT\override\classes\pdf\HTMLTemplateInvoice.php or PRETSASHOP_ROOT\classes\pdf\HTMLTemplateInvoice.php
• delivery-slip** tpl: Entry PHP class is PRETSASHOP_ROOT\override\classes\pdf\HTMLTemplateDeliverySlip.php or PRETSASHOP_ROOT\classes\pdf\HTMLTemplateDeliverySlip.php
• order-slip** tpl: Entry PHP class is PRETSASHOP_ROOT\override\classes\pdf\HTMLTemplateOrderSlip.php or PRETSASHOP_ROOT\classes\pdf\HTMLTemplateOrderSlip.php
• order-return** tpl: Entry PHP class is PRETSASHOP_ROOT\override\classes\pdf\HTMLTemplateOrderReturn.php or PRETSASHOP_ROOT\classes\pdf\HTMLTemplateOrderReturn.php
• supply-order*** tpl: Entry PHP class is PRETSASHOP_ROOT\override\classes\pdf\HTMLTemplateSupplyOrderForm.php or PRETSASHOP_ROOT\classes\pdf\HTMLTemplateSupplyOrderForm.php

Step 2: Open a Entry PHP Class, for an example we open file HTMLTemplateInvoice.php, each Entry PHP class extends from HTMLTemplate.php and it always have 3 main functions

• getHeader(): Assign data and execute to get the header of PDF file
• getFooter(): Assign data and execute to get the header of PDF file
• getContent(): Assign data and execute to get the header of PDF file

if you want assign new values from PHP to *.tpl PDF template file, you can use this function of Smarty

$this->smarty->assign(‘new_variable’, ‘new value’);

Example my image

Step 3: Open a *.tpl PDF file in PRESTASHOP_ROOT/pdf, print new value with statement:

{$new_variable1}
