发布时wordpress自定义帖子类型错误

Question

我在 Wordpress 中有 2 种自定义帖子类型:“主页”和“故事”，并且我安装了一个插件“从站点发布”。当我尝试使用此插件从首页发布到“故事”时，出现了一些错误。

您也可以在这里尝试:http://www.teenbetween.relationshipsireland.com/your-family-life/accepting-the-decision/ - 你会在下面的图片中找到一个链接，使用它。

文章已发布，但我收到错误消息。

这是 story.php 45:

if ( !current_user_can( 'edit_post', $post->ID )){
    return $post->ID;
}

和 homepage.php 79:

add_action('save_post', 'save_details');
function save_details(){ 
global $post;   
update_post_meta($post->ID, "link_homepage", $_POST["link_homepage"]);  // homepage.php 79
}

请问有什么帮助吗？

Answer 1

$post对象在 save_details 期间不可用功能。调用函数时，传入$post_id作为第一个参数。您还需要在 story.php 中移动授权码进save_details功能。

function save_details($post_id){ 
    update_post_meta($post_id, "link_homepage", $_POST["link_homepage"]);  // homepage.php 79
}
