对 prestashop PDF 生成过程感到困惑.处理逻辑的代码在哪里? [英] Confused about prestashop PDF generated process. Where is the code to handle the logic?

问题描述

想深入了解prestahop里面的结构，修改一些部分.我停在 PDF 中.我想找不到用于处理 AdminPdf 和 generateDeliverySlipPDF

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'}&amp;submitAction=generateDeliverySlipPDF&amp;id_order={$order->id}">
      <i class="icon-truck"></i>
    </a>
   {/if}

谁能帮我弄清楚内部流程?我找不到处理 generateDeliverySlipPDF 的方法.

Who can help me figure out the inside processes? I can't find the methods to handle generateDeliverySlipPDF.

推荐答案

AdminPdfController 位于 /controllers/admin/AdminPdfController.php.

url 的 submitAction=generateDeliverySlipPDF 部分将调用此控制器内的方法 processGenerateDeliverySlipPDF().

The submitAction=generateDeliverySlipPDF part of the url will call the method processGenerateDeliverySlipPDF() inside this controller.

这是这个方法:

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.'));
    }
}

在此控制器中，您将找到与此相同的其他方法来生成发票、订单...和其他 PDF.

In this Controller you'll find other methods as this one to generate Invoices, Order, ... and other PDFs.

如果您需要更多信息，请随时询问.

如果您想以适当的方式更改格式，您必须覆盖这些类:

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();
    }
}

现在您可以为每个 PDF 指定格式.您可以在 这里 找到有关 $format 的信息一个>

Now you can specify the format for each PDF. You will find informations about $format at this place

此代码尚未经过测试，但应该可以正常工作.如果您遇到任何问题，请告诉我.

This code has not been tested but should work as expected. Let me know if you encounter any issue.

在添加这些覆盖以清除 Prestashop 内部类路径缓存后，您需要删除 /cache/class_index.php.

You will need to delete /cache/class_index.php after adding those overrides to clear Prestashop internal classes path cache.
