ACF Repeater字段|加载更多内容

Question

我正在遵循一个Github代码来添加更多的负载到ACF中继器字段。我有101个字段，但加载更多不起作用。我也试过装窃听器。Ajax响应为0。可能是通过ajax，它不工作。我是否必须在functions.php文件上添加任何内容。Ajax响应为0。

<?php 

    /*
        The code in this file is an example off the code that you would use in your template to
        show the first X number of rows of a repeater

        I'm sure there are more elegant ways to do the JavaScript, but what's here will work
    */

    if (have_rows('gallery_work', 'option')) {
        // set the id of the element to something unique
        // this id will be needed by JS to append more content
        $total = count(get_field('gallery_work', 'option'));
        ?>
            <ul id="my-repeater-list-id">

这里只有两个文件示例中的一个文件。这是模板中的代码。本例的PHP端位于另一个PHP文件https://github.com/Hube2/acf-dynamic-ajax-select-example/tree/master/repeater-ajax-load-more中，其中包括您需要添加到functions.php文件中的WP AJAX操作。
