How to get Categories in Prestashop 8

[Carpe_diem]

Hi guys,

I am currently working on my first project on Prestashop 8. I have installed my custom module that was created for version 1.7. I can insert rows without a problem, but I can't edit rows because the categories. Here is my code that works in version 1.7 but not in version 8. 

        $categories = Category::getCategories($this->context->language->id, true, false, $this->context->shop->id);

        $filteredCategories = array_filter($categories, function ($category) {

           return $category['id_category'] != 2; // Exclude the "home" category

         });



 $fields_form = array(

              array(

                'type' => 'categories',

                'label' => $this->l('Kategorija'),

                'name' => 'id_category',

                'tree' => array(

                  'id' => 'category_tree',

                  'use_search' => false,

                  'use_checkbox' => true,

                'selected_categories' => !empty($data['id_category']) ? explode(',', $data['id_category']) : [],

                  'categories' => $filteredCategories,

                ),

                'hidden' => true,



              ),             
),

Could someone please help me solve this so it works in version 8.

Hello,

The following code should return the categories for the current shop:

$categories = Category::getCategories($this->context->language->id, true, false, 'AND `id_shop_default` = ' . $this->context->shop->id);

Let me know if it returns the expected data for you, please.

Hi,

In PS 8 and above versions, the fourth param is for Additional SQL clause(s) to filter results.
And you have passed shop_id in the param which might not be generating a proper query.

So, please try removing that fourth param.
$categories = Category::getCategories($this->context->language->id, true, false);

Regards
