Forms Prestashop用户组'；集团'；自定义模块中的表单帮助器

我想在from helper方法的模块中使用Customer group componnet（我在AdminPattern controller中找到它）。我可以将选中的复选框保存到配置表（我序列化了数组并将选项保存为文本），但无法将保存的值加载回表单

    array(
                    'type' => 'group',
                    'label' => 'group',
                    'name' => 'configuration[]',
                    'values' => Group::getGroups(Context::getContext()->language->id),
                ),

在后处理中：

if (Tools::isSubmit('submitTallerOrden'))
    {
        $_POST['configuration'] = implode(',', Tools::getValue('configuration'));
    }

以渲染形式，我有：

$this->fields_value['configuration[]'] = explode(',',$obj->configuration);

像AdminCustomerController

形式：

            array(
                'type' => 'group',
                'label' => $this->l('Group access'),
                'name' => 'groupBox',
                'values' => Group::getGroups($this->default_form_language, true),
                'required' => true,
                'col' => '6',
                'hint' => $this->l('Select all the groups that you would like to apply to this customer.')
            ),

在渲染形式中：

foreach ($groups as $group) {
        $this->fields_value['groupBox_'.$group['id_group']] =
            Tools::getValue('groupBox_'.$group['id_group'], in_array($group['id_group'], $customer_groups_ids));
    }
