php - 回声 AFC 图像子字段

问题描述

我试图从 AFC 图像字段中回显图像，但无法使其正常工作。

对于具有组名称 header_usps 和子字段名称 usp_1 的子字段的常规文本字段，请使用以下代码：

<?php $ups1 = get_field('header_usps_usp_1', 'option'); ?>
<?php echo $ups1; ?>

这很好用，但是当我尝试使用图像字段时，我似乎无法获取 url，而是显示“数组”。图像作为 URL 加载。

<?php $image1 = get_field('section_one_sideimage_one', 'option'); ?>
<img src="<?php echo $image1; ?>" alt="Image"></p>

Section_one 是组名，sideimage_one 是子字段。这样做的正确方法是什么？

解决方案

要访问子字段，您首先需要像这样获取组：

$section_one = get_field("section_one");

然后，您可以通过此变量获取子字段：

$image1 = $section_one["sideimage_one"];

如果要获取图片的url，请确保在创建字段时将返回格式设置为“URL”。

希望这可以帮助。
