Modul for Brand images

[Newbie25]

I'm trying to create my first Prestashop module, but I can't get it to work.
I want to display the manufacturer's logos on the manufacturer's page.
To do this, I've added the image_url column to the *_manufacturer table.

I've created the following files so that the standard theme is overwritten by my module.
I'm calling my module "ameinmodul" so that it is displayed as the first module in the list in the back office.
To do this, I've created the following files:

ameinmodul.php
/classes/ManufacturerHelper.php
/views/templates/hook/brand_miniature_item.tpl
/override/classes/Manufacturer.php

The files contain the following content:
ameinmodul.php
 

<?php
if (!defined('_PS_VERSION_')) {
    exit;
}

// Externe Klasse für die Bildverarbeitung einbinden
require_once(_PS_MODULE_DIR_ . 'ameinmodul/classes/ManufacturerHelper.php');

class AmeinModul extends Module
{
    public function __construct()
    {
        $this->name = 'ameinmodul';
        $this->tab = 'administration';
        $this->version = '1.0.10';
        $this->author = 'Mein Name';
        $this->need_instance = 0;

        parent::__construct();

        $this->displayName = $this->l('1 Mein Modul');
        $this->description = $this->l('Verschiedene Funktionen: Hersteller Logos');
    }

    public function install()
    {
        return parent::install()
            && $this->registerHook('displayBrandMiniatureItem') // **Hook explizit registrieren**
            && $this->registerHook('displayManufacturerLogo') // Herstellerlogo laden
    }



    public function hookDisplayManufacturerLogo($params)
    {
        error_log("HOOK WIRD AUFGERUFEN!", 3, _PS_ROOT_DIR_ . "/var/logs/hook_debug.log");

        if (!isset($params['manufacturer']) || !isset($params['manufacturer']['id_manufacturer'])) {

        }

        $manufacturer = $params['manufacturer'];
        $id_manufacturer = (int)$manufacturer['id_manufacturer'];
        $image_url = trim($manufacturer['image_url']);

        // Falls `image_url` leer ist, Standard-Pfad verwenden
        if (empty($image_url)) {
            $image_url = _PS_BASE_URL_ . "/img/m/" . $id_manufacturer . ".jpg";
        } else {

        }

        }

        // Bild ausgeben
        return '<img src="' . htmlspecialchars($image_url) . '" alt="' . htmlspecialchars($manufacturer['name']) . '" class="manufacturer-logo">';
    }

Do these hooks exist: hookDisplayBrandMiniatureItem & hookDisplayManufacturerLogo?

[Newbie25]

Hello QuickUpdate,

thanks for your quick reply.
Where do I have to place these hooks or can I do it without these hooks?
I would prefer to do everything in the modules or with override and not make any entries in the themes.
Thanks in advance

hookDisplayManufacturerLogo & hookDisplayManufacturerLogo kind of hook doesn't exist in the Pretashop. You need to create your own hook to use. 

 

Refer to the URL below to create own hook (Section: Going further: Creating your own hook)
https://devdocs.prestashop-project.org/8/modules/concepts/hooks/

 

Then call the hook in the manufacture page tpl. 

{hook h='hookName' mod='modulename'}

Use the existing Prestashop hooks if you do not want to change anything in your theme. Here is a complete list of hooks.

https://devdocs.prestashop-project.org/8/modules/concepts/hooks/list-of-hooks/

Also, you can manipulate the design of existing hooks using CSS.

If you will use a custom hook, then you need to put these hooks somewhere in your theme files as per your requirement.

Hello Webkul Solutions,

Thank you for your reply.
I've since solved it with an override, so I don't have to change anything in the themes.
