提问by Paul Sheldrake
I'm trying to get the captions from images in Wordpress but I can't find an easy function to grab this bit of information.

Anyone know a way to get this?

Turns out captions are stored as post excerpts. So,
原来字幕存储为帖子摘录。所以，
<?php echo $post->post_excerpt; ?>
will print out the caption if you are on the attachment image page (image.php in your theme) and inside the Loop.
如果您在附件图像页面（主题中的 image.php）和循环内，将打印出标题。

If you are trying to get the caption while in a post you can echo it out inside your "the_post_thumbnail" tag.
如果您想在帖子中获取标题，您可以在“the_post_thumbnail”标签中将其回显。
<?php the_post_thumbnail();
echo get_post(get_post_thumbnail_id())->post_excerpt; ?>
You can also use the same method to show the image description. This is a little better feature in WordPress 3.5
您也可以使用相同的方法来显示图像描述。这是 WordPress 3.5 中的一个更好的功能
<?php the_post_thumbnail();
echo get_post(get_post_thumbnail_id())->post_content; ?>
If you need to style the caption or description you can wrap it in a div like below.
如果您需要设置标题或描述的样式，您可以将其包装在如下所示的 div 中。
<?php the_post_thumbnail();
echo '<div class="myDiv">' . get_post(get_post_thumbnail_id())->post_excerpt . '</div>'
; ?>
Hope that helps.
希望有帮助。

Using Wordpress 4.8, this little guy worked for me:

Put this inside figure tag of your single.php file
把它放在你的 single.php 文件的图形标签中
$image_caption = get_post(get_post_thumbnail_id())->post_excerpt;
if(!empty($image_caption)) {
echo '<figcaption itemprop="caption">' . $image_caption . '</figcaption>';
}

I'm using this code, It works fine.
我正在使用此代码，它工作正常。
$get_description = get_post(get_post_thumbnail_id())->post_excerpt; if(!empty($get_description)){//If description is not empty show the div echo '<div class="img-caption">' . $get_description . '</div>'; }
