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


Recommended Posts

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:


    protected function initForm()
    {
        $default_lang = (int)Configuration::get('PS_LANG_DEFAULT');

        $this->fields_form[0]['form'] = array(
            'legend' => array(

    }

 

What do you think that is the problem !?

Thank you all.
