[英]Programmatically add featured image with ALT text in Wordpress?
There are examples of how to add post with featured image programmatically in wordpress, but I need to add post with featured image and ALT text too. 有一些示例如何在wordpress中以编程方式添加带有特色图片的帖子,但我也需要添加带有特色图片和ALT文本的帖子。 How can I do something like that?
我该怎么做?
Thank you. 谢谢。
If you look at the source for the wp_get_attachment_image
function, you can see how the alt text is being fetched: 如果查看
wp_get_attachment_image
函数的源代码,则可以看到如何获取替代文本:
'alt' => trim(strip_tags( get_post_meta($attachment_id, '_wp_attachment_image_alt', true) ))
From there it is easy enough to figure out how to update the alt text. 从那里很容易找出如何更新替代文本。
update_post_meta($attachment_id, '_wp_attachment_image_alt', 'My Alt Text');
