向轮播添加 Alt 标签

Question

我正在尝试将 alt 标签添加到我网站上的自定义船轮播和船页。不知道我需要添加什么 PHP 以及放在哪里。轮播和页面上的图像都是缩略图。

我有boat_page.php 和boat_carousel.php，这是我认为需要添加代码的地方。

不确定我是否应该将所有代码添加到这篇文章中。

这是指向页面https://www.embarkboathire.com.au/boats/的链接

您可以在底部看到每页 15 条船。

更改此行代码：

<img src="<?php echo $src[0]; ?>" />

到：

<img src="<?php echo $src[0]; ?>" alt="<?php echo get_post_meta(get_post_thumbnail_id( $post->ID ), '_wp_attachment_image_alt', true); ?>" />
