WordPress - 在从数据库下载之前更改post.php中的帖子内容

问题描述：

I have a form in single.php, it submits data to wp_update_post() on the same page. The problem is, whenever single.php loads, my update function launches after The Loop is already loaded and after it has already retrieved that post from the database.

I have to refresh the page to see any changes I made with wp_update_post().

This is how I update the post:

$queried_object = get_queried_object();
$my_post = get_post($queried_object->ID);

if(isset($_POST['submit']) && isset($_POST['singleedit'])) {
    $my_post->post_content = $_POST['singleedit'];
    wp_update_post($my_post);
}

Even if I put it just after the header it's launched after the post in question is downloaded from the DB.

Is there a way to change post's content in single.php before it's downloaded from the database?

EDIT: Excuse me, I realized that I wasn't clear enough. The form is for admins only, it's a wp_editor from which they can update post's content. I already managed all of the layout concerns etc. I want admins to be able to modify the content of the post they're viewing.

我在single.php中有一个表单，它将数据提交给wp_update_post（） code> 同一页面。问题是，每当single.php加载时，我的更新函数在已经加载循环之后以及它已经从数据库中检索到该帖子之后启动。 p>

我必须刷新页面到看看我用 wp_update_post（） code>做的任何更改。 p>

这是我更新帖子的方式： p>


   $ queried_object = get_queried_object（）; 
 $ my_post = get_post（$ queried_object-＆gt; ID）; 
 
if（isset（$ _ POST ['submit']）＆amp;＆amp; isset（$ _ POST ['singleedit']  ））{
 $ my_post-＆gt; post_content = $ _POST ['singleedit']; 
 wp_update_post（$ my_post）; 
} 
  code>  pre> 
 
 即使 我把它放在从数据库下载有问题的帖子之后启动的标题之后。 p> 
 
 
 有没有办法在single.php下载之前更改帖子的内容 数据库？ strong>  p> 
 
 
编辑：对不起，我意识到我不够清楚。 该表单仅供管理员使用，它是一个wp_editor，可以从中更新帖子的内容。 我已经管理了所有布局问题等。我希望管理员能够修改他们正在查看的帖子的内容。 p> 
  div>

答

Generally speaking, you don't want "update" actions to re-render form content. If the user presses refresh on the page, they will get the whole "Are you sure you want to resubmit the form data?" popup. Instead, you'd just want to redirect the user back to the single page after a successful update. And thus, the post would be updated. So after wp_update_post, just call wp_redirect( get_the_permalink() );
