【问题描述】：

在我的 WordPress 网站上，我安装了 ACF 插件，并以“常规”方式使用多个页面上的字段。所以我在后端创建了组和字段。一切正常。

现在我想生成其中几个字段组的 php 代码（因为我想稍微更改代码）。我将代码放在哪里？最好的方法是什么？

我创建了一个新的 php 文件 acf-deals.php 并将其上传到根目录下的 /php-includes/ 目录。它包括以下代码：

<?php

if( function_exists('acf_add_local_field_group') ):

acf_add_local_field_group(array(
    'key' => 'group_deal1',
    'title' => 'Deal One (displayed on homepage)',
    'fields' => array(
        array(
            'key' => 'field_5c66e017f8359',
            'label' => 'Title',
            'name' => 'deal_title_one',
            'type' => 'text',
            'instructions' => '(max. 100 characters)',
            'required' => 0,
            'conditional_logic' => 0,
            'wrapper' => array(
                'width' => '',
                'class' => 'deals-title',
                'id' => '',
            ),
            'default_value' => '',
            'placeholder' => '',

            'append' => '',
            'maxlength' => 100,
        ),
        array(

    'hide_on_screen' => '',
    'active' => 1,
    'description' => '',
));

endif;

?>

我已将此代码添加到我的 single-aside.php 文件中：

<?php get_template_part( '/php-includes/acf-deals.php', 'acf-deals' ); ?>

不幸的是，该字段未显示在 WP 管理后端。我究竟做错了什么？我搜索和搜索，但找不到正确的解释或修复它的方法。我希望有人可以提供帮助。

感谢您的帮助！
