[英]How to use get_post_meta to get thumbnail in wordpress
I have a wordpress website and I am trying to get the thumbnail image (aka featured image) of a post. 我有一个wordpress网站,我正在尝试获取帖子的缩略图(又称特色图片)。 I can't use the below function because I am not in a loop for reason relating to layout.
我不能使用以下功能,因为由于布局原因我不在循环中。
the_post_thumbnail_url( )
I am just wondering whether I can get the thumbnail of the post via this function. 我只是想知道是否可以通过此功能获取帖子的缩略图。
$thumb_1 = get_post_meta( '40', 'thumb', true ); //40 is the post_id
I can pretty much retreive all other custom fields but, retrieving thumb seems to not work. 我几乎可以检索所有其他自定义字段,但是,检索thumb似乎不起作用。 Does anyone knows what is the "key" for the thumbnail image?
有谁知道缩略图的“关键”是什么?
Perhaps a better way to do this would be to use the function get_the_post_thumbnail_url(), which lets you pass in a post ID (and doesn't need to be in the loop: 也许更好的方法是使用函数get_the_post_thumbnail_url(),该函数可让您传递帖子ID(并且无需循环:
https://developer.wordpress.org/reference/functions/get_the_post_thumbnail_url/ https://developer.wordpress.org/reference/functions/get_the_post_thumbnail_url/
so $thumb = get_the_post_thumbnail_url(40);
所以
$thumb = get_the_post_thumbnail_url(40);
