Extend Manufacturer with new fields - object and Twig theme

[limera1n]

Hi all,

I am using Presta 1.7.7.7, I would like to extend manufacturer object with few new text fields which I want to use in product page template later.

Based on these docs: https://devdocs.prestashop.com/1.7/modules/concepts/templating/admin-views/

I created new file under this path: PRESTA_DIR/modules/extrafields/views/PrestaShop/Admin/Sell/Catalog/Manufacturer/Blocks/form.html.twig

Inside of the file I put this code:

{% extends 'PrestaShopBundle:Admin/Sell/Catalog/Manufacturer/Blocks:form.html.twig' %}

{% block manufacturer_form_rest %}
Hello world!
{% endblock %}

also, I created class override: PRESTA_DIR/override/classes/Manufacturer.php

Inside of this file I put this code:

<?php

class Manufacturer extends ManufacturerCore {

    public $photo_url;

    public function __construct($id_manufacturer = null, $id_lang = null) {
        self::$definition['fields']['photo_url'] = array('type' => self::TYPE_STRING);
        parent::__construct($id_manufacturer, $id_lang);
    }
}

Basically - nothing works. I cannot see "Hello world!" on manufacturer editing screen.

I understand that I should also take care of new column in database but first I would like to fix this issue.

Do you have any experience with creating new fields for manufacturer on Presta 1.7? What else should I try?

Check out the module for additional category description:

You can create additional fields for manufacturers the same way, without messing with twig templates or making overrides.

Hi Daresh, thanks for this.

I am just wondering if there are any replacement hooks (for example hookActionAdminCategoriesFormModifier) which I could use for Manufacturer. Presta 1.7 documentation is a joke 😕

Yes: hookActionAdminManufacturersFormModifier

I have managed to add new field to Manufacturer edit screen by modifying hooks names ('Categories' keywords changed to 'Manufacturers' etc.), but still few more issues:

• [PrestaShop\PrestaShop\Core\Domain\Manufacturer\Exception\ManufacturerException kod 0]: Cannot update manufacturer with id "2"

  this is what I get after trying to update Manufacturer, Symfony debug shows nothing

• what is the best way to access these values from template level?

Ok, nevermind, the problem was with some custom code that I had in my Presta before. 

I managed to prepare working module based on your solution and extend Manufacturer with 3 another fields, thank you @Daresh
