Overriding Suppliers to add gallery

[naulacambra]

Hello,

 

it's been 1 week since I've started to work on this. My target is to add a gallery field to the suppliers form in the admin panel.

 

I'm trying to use the same gallery field that use Categories.

 

I've already overrided the suppliers controller.

class AdminSuppliersController extends AdminSuppliersControllerCore {

   public function renderForm() {
        // loads current warehouse
        if (!($obj = $this->loadObject(true)))
            return;

        $image = _PS_SUPP_IMG_DIR_ . $obj->id . '.jpg';
        $image_url = ImageManager::thumbnail($image, $this->table . '_' . (int) $obj->id . '.' . $this->imageType, 350, $this->imageType, true, true);
        $image_size = file_exists($image) ? filesize($image) / 1000 : false;

        $tmp_addr = new Address();
        $res = $tmp_addr->getFieldsRequiredDatabase();
        $required_fields = array();
        foreach ($res as $row)
            $required_fields[(int) $row['id_required_field']] = $row['field_name'];

        $this->fields_form = array(
            'legend' => array(
                'title' => $this->l('Suppliers'),
                'icon' => 'icon-truck'
            ),
            'input' => array(
                array(
                    'type' => 'hidden',
                    'name' => 'id_address',
                ),
                array(
                    'type' => 'text',
                    'label' => $this->l('Name'),
                    'name' => 'name',
                    'required' => true,
                    'col' => 4,
                    'hint' => $this->l('Invalid characters:') . ' <>;=#{}',
                ),
                (in_array('company', $required_fields) ?
                        array(
                    'type' => 'text',
                    'label' => $this->l('Company'),
                    'name' => 'company',
                    'display' => in_array('company', $required_fields),
                    'required' => in_array('company', $required_fields),
                    'maxlength' => 16,
                    'col' => 4,
                    'hint' => $this->l('Company name for this supplier')
                        ) : null
                ),
                array(
                    'type' => 'textarea',

                ),
                array(

                'postcode' => $address->postcode,
                'city' => $address->city,
                'id_country' => $address->id_country,
                'id_state' => $address->id_state,
            );
        } else
            $this->fields_value = array(
                'id_address' => 0,
                'id_country' => Configuration::get('PS_COUNTRY_DEFAULT')
            );


        if (Shop::isFeatureActive()) {
            $this->fields_form['input'][] = array(
                'type' => 'shop',
                'label' => $this->l('Shop association'),
                'name' => 'checkBoxShopAsso',
            );
        }

        return AdminController::renderForm();
    }

Note that also i've added some other fields, but they don't affect this matter.

 

The important line that i've copied from the CategoriesController is 

$this->tpl_form_vars['displayBackOfficeCategory'] = Hook::exec('displayBackOfficeCategory');

Also, i've overrided the ModuleCore to add to the Suppliers Module the hook displayBackOfficeCategory.

class Module extends ModuleCore {

    protected $allowed_mod = array(
        'displayBackOfficeCategory' => array('blocksupplier'),
    );

    public function hookDisplayBackOfficeCategory($params) {
        if (in_array($this->name, $this->allowed_mod['displayBackOfficeCategory'])) {
            if (Context::getContext()->controller->className == 'Supplier') {
                $supplier = new Supplier((int) Tools::getValue('id_supplier'));
                $files = array();
                
                for ($i = 0; $i < 3; $i++) {
                    if (file_exists(_PS_SUPP_IMG_DIR_ . (int) $supplier->id . '-' . $i . '_thumb.jpg')) {
                        $files[$i]['type'] = HelperImageUploader::TYPE_IMAGE;
                        $files[$i]['image'] = ImageManager::thumbnail(_PS_SUPP_IMG_DIR_ . (int) $supplier->id . '-' . $i . '_thumb.jpg', $this->context->controller->table . '_' . (int) $supplier->id . '-' . $i . '_thumb.jpg', 100, 'jpg', true, true);
                        $files[$i]['delete_url'] = Context::getContext()->link->getAdminLink('AdminBlockCategories') . '&deleteThumb=' . $i . '&id_supplier=' . (int) $supplier->id;
                    }
                }

                $helper = new HelperImageUploader();
                $helper->setMultiple(true)->setUseAjax(true)->setName('thumbnail')->setFiles($files)->setMaxFiles(3)->setUrl(
                        Context::getContext()->link->getAdminLink('AdminBlockCategories') . '&ajax=1&id_supplier=' . $supplier->id
                        . '&action=uploadThumbnailImages');
                $this->smarty->assign('helper', $helper->render());
                return $this->display(_PS_MODULE_DIR_ . '/blocksupplier/blocksupplier.php', 'views/blocksupplier_admin.tpl');
            }
        } else {
            return false;
        }
    }

}

But doesn't work. I know that the hook is been firing, but the admin panel doesn't change. What i'm missing? Any help will be very welcome!
