Error 500 in Module Development (display custom background in product detail page).

[ricardo21ferreira]

Hi.

I'm developing a module to add a custom background in the product detail page.

To do that, i created a module that hooks in: hookDisplayAdminProductsExtra, but when i try to do $helper->generateForm($this->fields_form) i get:

SmartyException  Twig_Error_Runtime
HTTP 500 Internal Server Error
An exception has been thrown during the rendering of a template ("Unable to load template 'file:helpers/uploader\simple.tpl'").

Twig_Error_Runtime
in src\PrestaShopBundle\Resources\views\Admin\Product\ProductPage\product.html.twig (line 161)
             

{% set hooks = renderhooksarray('displayAdminProductsExtra', { 'id_product': id_product }) %}

my methods:

Override of /classes/Product.php is possbile. Check the documentation https://devdocs.prestashop.com/1.7/modules/concepts/overrides/

Have you cleared the override classes file after you've placed your override?
