我正尝试使用首页作为特色图片的默认排序方式(例如,如果未设置特色图片,则想使用首页的图片)

但是我在寻找如何以安全的方式获取首页的帖子ID时遇到了麻烦(因此当有人不可避免地更改首页时,我的代码仍然可以工作)

我知道我可以在代码中硬编码一个ID,但是当有人决定使用新的内容项作为首页时,这会中断.

我是否必须使用wp-query来实现?如果是这样,使用wp-query实现此目标的安全方法是什么?

I'm trying to use the front page as a default of sorts for featured images (if no featured image is set, I want to use the front page's, for example)

But I'm having trouble finding out how to get the post ID of the front page in a safe manner (so that my code still works when the front page is inevitably changed by someone)

I know I could just hard code an ID in my code, but that'll break when someone decides to use a new content item as the front page.

Would I have to use wp-query to achieve this? And if so, what is a safe way to achieve this with wp-query?

wp-query homepage

WordPress有一些有用的选项.您可以使用以下方法获取主页ID:

$frontpage_id = get_option( 'page_on_front' );

或通过使用以下博客ID:

$blog_id = get_option( 'page_for_posts' );

此处列出了许多有用的get_option参数.
WordPress has a few useful options. You can get the homepage ID by using the following:

$frontpage_id = get_option( 'page_on_front' );

or the blog ID by using:

$blog_id = get_option( 'page_for_posts' );

Here's a list of many useful get_option parameters.
- 如果您希望将其设为INTEGER,则get_option(...)将返回ID=STRING=>执行(最快)直接类型强制转换为((int)`=>例如:`$frontpage_id=(int)get_option('page_on_front');`
  
  `get_option(...)` will return the id as STRING, if you want it to be an INTEGER => do (fastest) direct type cast `(int)` => eg.: `$frontpage_id = (int)get_option( 'page_on_front' );`

您应该可以使用$front_page_id = get_option( 'page_on_front' );

它将返回您正在用作网站首页的页面的ID；如果尚未设置,则返回0.

Codex: get_option()

You should be able to use $front_page_id = get_option( 'page_on_front' );

It'll return the ID of the page you're using as your site's front page, or 0 if it hasn't been set.
