在帮助表单 Prestashop 中动态添加表单字段

Question

我有一个后台管理控制器，我在其中使用 renderform() 中的辅助表单来生成一个表单，它正在工作，但我想要一个功能来动态地在该表单中添加一个字段。

Answer 1

我已经通过 helper list 完成了这个，同时渲染表单我也返回了一个渲染列表，检查 renderAdditionalOptionsList() 用法

public function renderForm() {
    $id_citydelivery = (int) Tools::getValue('id_citydelivery');
    $citydeliveryObj = new CityPortModel($id_citydelivery);
    if (Validate::isLoadedObject($citydeliveryObj)) {
        $_legends = $citydeliveryObj->legend;
        $_legend_array = explode(',', $_legends);
        foreach ($_legend_array as $_legend) {
            $this->fields_value['legend_' . $_legend] = $_legend;
        }
    }
    $temp = $this->fields_value;
    $fields_form_1 = array(
        'form' => array(
            'legend' => array('title' => $this->l('Price and Delivery Destination Manager'), 'icon' => 'icon-cogs'),
            'input' => array(
                array(
                    'type' => 'select',
                    'label' => $this->l('Country'),
                    'name' => 'id_country',
                    'required' => false,
