重力形式 - 动态创建单个产品字段

Question

我正在尝试通过自定义 post 类型为我的表单动态创建新字段（单个产品）。这在前端工作得很好。现在，一个问题是，一旦提交了表单，除了这些动态添加的字段之外的所有字段都在提交中。另一个问题是，总计字段（根据计算需要）也忽略了动态创建的。

我想这与挂钩有关。但是我尝试的每一个钩子都没有改变任何东西。

add_filter( 'gform_form_post_get_meta_1', 'populate_beers');

function populate_beers($form) {

                    $new_field_id = 0;
                        foreach( $form['fields'] as $field ) {
                            if( $field->id > $new_field_id ) {
                                $new_field_id = $field->id;
                            }
                        }

                    $new_field_id++;
            $beers = get_posts( 'numberposts=-1&post_status=publish&post_type=bier' );
                    //var_dump($beers);

                    foreach ( $beers as $beer ) {
                                  // Prepare field properties
                            $props = array(
                                'id'        => $new_field_id,
                                'type'      => 'singleproduct',
                                'label'     => $beer->post_title,
                                'basePrice' => floatval( $beer->preis ),
                                'enableCalculation' => true
                            );
                                    //var_dump($props);

                            // Create new gravity forms field and add it to the form object
                            $nf = GF_Fields::create( $props );

                            // Hack - insert into array at specific position
                            // Needed to display product fields before other fields
                            // in the form
                            array_splice( $form['fields'], 5, 0, array($nf) );

                            $new_field_id++;
                        }

        return $form;
}

我也已经尝试过这些钩子了：

add_filter( 'gform_pre_process_1', 'populate_beers' );
add_filter( 'gform_pre_render_1', 'populate_beers' );

{all_fields} 和 {pricing_fields} 没有显示那些产品字段、总计和运输字段。

您忘记在属性中定义所需的 inputType。

在 gravityforms 中定义动态产品的正确方法是将其声明为 type => product，定义 inputType，如 singleproduct，不要忘记添加 [=如果您将 singleproduct 用作 inputType.

，则将 17=] 数组添加到属性中

示例：

$props = array(
    'id' => $new_field_id,
    'type' => 'product',
    'inputType' => 'singleproduct',
    'label' => $beer->post_title,
    'basePrice' => floatval( $beer->preis ),
    'enableCalculation' => true,
    'inputs' => array(
        array(
            'id'    => $new_field_id.'.1',
            'label' => $beer->post_title,
            'name'  => 'param_product'
        ),
        array(
            'id'    => $new_field_id.'.2',
            'label' => 'Price',
            'name'  => 'param_price'
        ),
        array(
            'id'    => $new_field_id.'.3',
            'label' => 'Quantity',
            'name'  => 'param_qty'
        ),
    ),
);

重力形式产品的可用输入类型为：

单一产品
select
收音机
价格
隐藏产品
计算

也尝试像这样向您的表单添加动态总计计算：

$calculation = GF_Fields::create(array(
    'id' => 1000,
    'label' => 'Totals',
    'type' => 'total',
));
array_push( $form['fields'], $calculation );

您的 Gravityforms Hook 应该可以工作：

add_filter( 'gform_form_post_get_meta_1', 'populate_beers' );
