Vaguely about the forewash created by the PDF process. Where is the code for processing logic?

Question

I want to deeply understand prestahop inside the structure and change some parts. I have stopped at pdf. I can not find the controller used to handle AdminPdf and generateDeliverySlipPDF

    {if $order->delivery_number}
      <a class="btn btn-default _blank" href="{$link->getAdminLink('AdminPdf')|escape:'html':'UTF-8'}&amp;submitAction=generateDeliverySlipPDF&amp;id_order={$order->id}">
      <i class="icon-truck"></i>
    </a>
   {/if}

Who can help me figure out the internal processes? I can not find methods to handle generateDeliverySlipPDF.

Answer 1

AdminPdfControllerlocated in /controllers/admin/AdminPdfController.php.

Part of the submitAction=generateDeliverySlipPDFURL will invoke the method processGenerateDeliverySlipPDF()inside this controller.

Here is the 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.'));
    }
}
