ACF 以编程方式添加中继器

Question

我正在使用高级自定义字段 （ACF） 并尝试以编程方式将中继器添加到现有组 （group_5621b0871e1b1），但它不起作用。相同的代码适用于文本字段，但不适用于转发器。

在我的插件中：

add_action( 'acf/init', 'acf_add_field_royalties' );
function acf_add_field_royalties() {
    if ( function_exists( 'acf_add_local_field_group' ) ) {
        acf_add_local_field( array (
            'key' => 'field_store_royalties',
            'label' => 'Royalties',
            'name' => 'store_royalties1',
            'type' => 'repeater',
            'parent'       => 'group_5621b0871e1b1',
            'instructions' => '',
            'required' => 0,
            'conditional_logic' => 0,
            'wrapper' => array (
                'width' => '',
                'class' => '',
                'id' => '',
            ),
            'collapsed' => '',
            'min' => '',
            'max' => '',
            'layout' => 'table',
            'button_label' => 'Add new royalty period',
            'sub_fields' => array (
                array (
                    'key' => 'field_start_date',
                    'label' => 'Start Date',
                    'name' => 'start_date1',
                    'type' => 'date_picker',
                    'instructions' => '',
                    'required' => 1,
                    'display_format' => 'F j, Y',
                    'return_format' => 'd/m/Y',
                    'first_day' => 1,
                ),
                array (
                    'key' => 'field_end_date',
                    'label' => 'End date',
                    'name' => 'end_date1',
                    'type' => 'date_picker',
                    'instructions' => '',
                    'display_format' => 'F j, Y',
                    'return_format' => 'd/m/Y',
                    'first_day' => 1,
                ),
                array (
                    'key' => 'field_royalty_rate',
                    'label' => 'Royalty Rate',
                    'name' => 'royalty_rate1',
                    'type' => 'number',
                    'instructions' => '',
                    'required' => 1,
                    'wrapper' => array (
                        'width' => '',
                        'class' => '',
                        'id' => '',
                    ),
                    'default_value' => 0,
                    'placeholder' => '',
                    'prepend' => '',
                    'append' => '%',
                    'min' => 0,
                    'max' => 100,
                    'step' => 1,
                    'readonly' => 0,
                    'disabled' => 0,
                )
            )
        ));
    }
}

它在group_5621b0871e1b1组中显示此错误：

Warning: Invalid argument supplied for foreach() in /usr/share/nginx/html/wordpress4/wp-content/plugins/advanced-custom-fields-pro/pro/fields/repeater.php on line 255
Warning: Invalid argument supplied for foreach() in /usr/share/nginx/html/wordpress4/wp-content/plugins/advanced-custom-fields-pro/pro/fields/repeater.php on line 320

我做错了什么吗？是否可以以编程方式添加中继器。

Answer 1

由于中继器字段是使用 acf_add_local_field 添加的，因此每个子字段也需要添加acf_add_local_field。

• 删除所有子字段，包括'subfields' => array行，来自中继器字段。
• 在新acf_add_local_field中添加每个子字段
添加子字段
• 时，请确保向子字段添加'parent' => 'repeater_field_key'。

您的代码现在如下所示：

add_action( 'acf/init', 'acf_add_field_royalties' );
function acf_add_field_royalties() {
    if ( function_exists( 'acf_add_local_field_group' ) ) {
        /** 
         * Initial Repeater Field
         *
         */
        acf_add_local_field( array (
            'key'               => 'field_store_royalties',
            'label'             => 'Royalties',
            'name'              => 'store_royalties1',
            'type'              => 'repeater',
            'parent'            => 'group_5621b0871e1b1',
            'instructions'      => '',
            'required'          => 0,

            'wrapper'           => array (
