通过插件发布后编辑帖子？

我正在尝试编写一个插件来编辑已发布帖子的内容。我尝试过使用这个：

function edit( $post_ID ) {
    $content = "Hello. This is a test.";

    $post_info = get_post($post_ID);    
    $post_info->post_content = "$content";

    wp_update_post( $post_info );
}

add_action('publish_post', 'edit');

虽然那不起作用。它进入一个循环（因为它正在再次发布）并且仅在超时时结束。还有其他方法可以做到这一点吗？

I'm trying to write a plugin which edits the content of a published post. I've tried using this:

function edit( $post_ID ) {
    $content = "Hello. This is a test.";

    $post_info = get_post($post_ID);    
    $post_info->post_content = "$content";

    wp_update_post( $post_info );
}

add_action('publish_post', 'edit');

Although that's not working. It enters a loop (because it's being published again) and only ends when it times out. Would there be another way to do this?

我认为函数中必须有一个静态变量来跟踪该函数是否已被调用。另外，wp_update_post 接受一个数组而不是一个对象——至少我是这样做的。

function edit( $post_ID ) {
    static $plugin_has_updated = false;
    if ($plugin_has_updated) return;
    $plugin_has_updated = true;
    $content = "Hello. This is a test.";
    $post_arr = array("ID"=>$post_ID, "post_content"=>$content);
    wp_update_post( $post_arr );
}

add_action('publish_post', 'edit');

I think you have to have a static variable in the function that tracks whether the function has been called. Also, wp_update_post takes an array rather than an object -- at least that's the way I do it.

function edit( $post_ID ) {
    static $plugin_has_updated = false;
    if ($plugin_has_updated) return;
    $plugin_has_updated = true;
    $content = "Hello. This is a test.";
    $post_arr = array("ID"=>$post_ID, "post_content"=>$content);
    wp_update_post( $post_arr );
}

add_action('publish_post', 'edit');
