我试图在我的网站上创建一个特色帖子部分,其中涉及三个文件:
header.php
footer.php
functions.php
index.php我想要选择一个特色帖子只是通过选中编辑屏幕(帖子页面)中的一个复选框,并能够在首页检索这些特色文章。
到目前为止,在我当前的代码中,它只在posts页面编辑屏幕上显示一个复选框,但是它不会保存,并且在首页上除了posts循环之外什么也没有显示。

index.php工作得很好,但在functions.php on save_post操作页中导致问题的某些内容未进入function save_featured_meta($post_id){}
要检查这一点,请添加admin_init而不是save_post,并在上面的函数中回显它正在显示的内容,但在save_post上它没有输入函数。
而不是save_post,尝试使用
edit_post或
pre_post_update或
post_updated
