I want to deep understand prestahop inside structure and amend some parts. I am stoped in the PDF. I want can't find the controller used to handle the AdminPdf and generateDeliverySlipPDF
{if $order->delivery_number}
<a class="btn btn-default _blank" href="{$link->getAdminLink('AdminPdf')|escape:'html':'UTF-8'}&submitAction=generateDeliverySlipPDF&id_order={$order->id}">
<i class="icon-truck"></i>
</a>
{/if}
Who can help me figure out the inside processes? I can't find the methods to handle generateDeliverySlipPDF.
AdminPdfController
is located at /controllers/admin/AdminPdfController.php
.
The submitAction=generateDeliverySlipPDF
part of the url will call the method processGenerateDeliverySlipPDF()
inside this controller.
Here is this method:
public function processGenerateDeliverySlipPDF()
{
if (Tools::isSubmit('id_order')) {
$this->generateDeliverySlipPDFByIdOrder((int)Tools::getValue('id_order'));
} elseif (Tools::isSubmit('id_order_invoice')) {
$this->generateDeliverySlipPDFByIdOrderInvoice((int)Tools::getValue('id_order_invoice'));
} elseif (Tools::isSubmit('id_delivery')) {
$order = Order::getByDelivery((int)Tools::getValue('id_delivery'));
$this->generateDeliverySlipPDFByIdOrder((int)$order->id);
} else {
die(Tools::displayError('The order ID -- or the invoice order ID -- is missing.'));
}
}
In this Controller you'll find other methods as this one to generate Invoices, Order, ... and other PDFs.
Feel free to ask if you need more informations.
EDIT:
If you want to change format in a proper way you'll have to override those classes:
/override/classes/pdf/PDFGenerator.php
:
<?php
/**
* @since 1.5
*/
class PDFGenerator extends PDFGeneratorCore
{
/**
* @param bool $use_cache
* @param string $orientation
* @param string $format
*/
public function __construct($use_cache = false, $orientation = 'P', $format = 'A4')
{
TCPDF::__construct($orientation, 'mm', $format, true, 'UTF-8', $use_cache, false);
$this->setRTL(Context::getContext()->language->is_rtl);
}
}
/override/classes/pdf/PDF.php
:
<?php
/**
* @since 1.5
*/
class PDF extends PDFCore
{
/**
* @param $objects
* @param $template
* @param $smarty
* @param string $orientation
*/
public function __construct($objects, $template, $smarty, $orientation = 'P', $format = 'A4')
{
parent::__construct($objects, $template, $smarty, $orientation);
$this->pdf_renderer = new PDFGenerator((bool)Configuration::get('PS_PDF_USE_CACHE'), $orientation, $format);
}
}
/override/controllers/admin/AdminPdfController.php
:
<?php
class AdminPdfController extends AdminPdfControllerCore
{
public function generatePDF($object, $template)
{
switch($template) {
case PDF::TEMPLATE_DELIVERY_SLIP:
$format = array(210, 50000); // Replace with your desired size
break;
default:
$format = 'A4';
}
$pdf = new PDF($object, $template, Context::getContext()->smarty, 'P', $format);
$pdf->render();
}
}
Now you can specify the format for each PDF.
You will find informations about $format
at this place
This code has not been tested but should work as expected. Let me know if you encounter any issue.
You will need to delete /cache/class_index.php
after adding those overrides to clear Prestashop internal classes path cache.
