Adding custom field in product page and admin panel

[Jakubek]

Hi, I'm trying to add custom field in product page and admin panel

1. I added field in my database in ps_product_lang

2. In overrides/classes/Product.php:

public function __construct($id_product = null, $full = false, $id_lang = null, $id_shop = null, Context $context = null)
       {
           self::$definition['fields']['price_week'] = array('type' => self::TYPE_STRING, 'shop' => true, 'validate' => 'isGenericName');
       }

3. In src/PrestaShopBundle/Form/Admin/Product/ProductInformation.php
 

  ->add('price_week', FormType\TextType::class, [
              'label' => $this->translator->trans('Cena za tydzień', [], 'Admin.Global'),
              'required' => false,
          ])

 

4. In src/PrestaShopBundle/Model/Product/AdminModelAdapter.php:

private $translatableKeys = array(
	//...LINE 140
	'price_week',
);
private $unmapKeys = array(
	//... LINE 161
	'price_week',
);
private function mapStep1FromData(Product $product)
{	
	return array(
		//... LINE 518
		'price_week' => $product->price_week,
	);
}

 

5. In src/PrestaShopBundle/Resources/views/Admin/Product/ProductPage/product.html.twig:

{# PANEL ESSENTIALS #}
        {% block product_panel_essentials %}
          {% set formQuantityShortcut = form.step1.qty_0_shortcut is defined ? form.step1.qty_0_shortcut : null  %}
          {{ include('@Product/ProductPage/Panels/essentials.html.twig', {
              'formPackItems': form.step1.inputPackItems,
              'productId': id_product,
              'images': form.step1.vars.value.images,
              'formShortDescription': form.step1.description_short,
              'formDescription': form.step1.description,
              'formManufacturer': form.step1.id_manufacturer,
              'priceWeek': price_week, // NEW ENTERY
              'formFeatures': form.step1.features,
              'formManufacturer': form.step1.id_manufacturer,
              'formRelatedProducts': form.step1.related_products,
              'is_combination_active': is_combination_active,
              'has_combinations': has_combinations,
              'formReference': form.step6.reference,
              'formQuantityShortcut': formQuantityShortcut,
              'formPriceShortcut': form.step1.price_shortcut,
              'formPriceShortcutTTC': form.step1.price_ttc_shortcut,
              'formCategories': form.step1,
            })
          }}
        {% endblock %}

 

6. In src/PrestaShopBundle/Resources/views/Admin/Product/ProductPage/Panels/essentials.html.twig (in right column):

<div class="form-group mb-4">
         <h2>Cena za tydzień</h2>
           <div class="input-group money-type week-price">
           {{ form_widget(priceWeek) }}
           <div class="input-group-append">
         <span class="input-group-text"> zł</span>
       </div>
   </div>
</div>

7. In product-prices.tpl

<td><span>{$product.price_week}</span></td>

Im not getting any errors, but its not saving and the span in the product page is empty. What is wrong with my code?

I think it is not good idea overrding core file, any update will be painfull for you, better way is create custom module here is sample module https://github.com/PululuK/democustomfields17
