出于测试目的，我编辑了页面。php除了：
<?php while ( have_posts() ) : the_post(); ?>
<h1><?php the_title(); ?></h1>
<?php $site_options = get_fields(\'options\'); ?>
<?php endwhile; ?>
我删除了get\\u header、get\\u footer，只启用了ACF插件，因为我还处于开发早期，正在进行一些初始测试。当我在不调用get\\u字段的情况下查看页面时，它会报告9个查询，但如果我访问带有get\\u字段的页面，它会跳到72个查询。看起来应该只会增加1到2个查询。。。不是63。
查询报告使用：
get_num_queries();
get\\u选项调用的结果：

我应该担心这个吗？

这会生成比您预期的更多的查询，有几个原因。
首先，ACF将字段存储为两个不同的数据段—一部分包含有关字段的信息、您选择的设置、输出格式等，另一部分包含分配给该字段的实际值。因此，每个字段都有一个额外的查询-字段数据加上字段的元数据。
另一个原因与您拥有的字段类型以及设置格式选项的方式有关。例如，图像字段似乎具有加载选定图像对象的选项。这意味着对于每个图像引用，ACF必须查询附件图像URL和元数据，这将为每个图像生成额外的查询。
你应该关心这个吗？
首先，应该注意的是，ACF的文件建议不要使用get_fields 如果您知道字段名和/或不会在每次页面加载时使用所有这些数据，因为函数使用的是低效的LIKE 查询以查找所有字段名称。
如果性能成为一个问题，您可以做以下几件事：1。使用缓存插件减少负载，和/或2。在数据更改时自己缓存数据。钩住acf/save_post 操作并将所有数据保存为单个选项中的数组，然后可以使用单个get_option 前端查询。
