[英]Background-image is not being displayed
I'm pulling a featured image in from a blog post and setting to my background image.我正在从博客文章中提取特色图片并设置为我的背景图片。 I'm using the same line of code I usually do, but for some reason no image is being displayed.
我使用的是我通常使用的同一行代码,但由于某种原因没有显示图像。
$img = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'full');
<div class="panel--bg-image" <?php $img ? print 'style="--background-image: url(' . $img['sizes']['large'][0] . ');"' : ''; ?>>
To make sure my variable isn't empty, I ran为了确保我的变量不为空,我跑了
var_dump($img)
and my image is indeed being called.我的形象确实被调用了。 When I check the element in the dev tools, I see this:
当我检查开发工具中的元素时,我看到:
When an image is successfully being called, I can always see the file in the url().成功调用图像后,我始终可以在 url() 中看到该文件。 I usually pull these images from a custom filed, but these are being pulled from 'featured image' in the post backend.
我通常从自定义文件中提取这些图像,但这些图像是从帖子后端的“特色图像”中提取的。 Any idea what I'm doing wrong here?
知道我在这里做错了什么吗?
The WordPress function wp_get_attachment_image_src
requires the Image-ID and the size and returns an array: WordPress 函数
wp_get_attachment_image_src
需要 Image-ID 和大小并返回一个数组:
array {
[0] => url,
[1] => width
[2] => height
[4] => is_intermediate
}
So, if you want to get the Image-URL, use $img[0]
instead of $img['sizes']['large'][0]
.因此,如果您想获取图像 URL,请使用
$img[0]
而不是$img['sizes']['large'][0]
。
