wordpress 自定义帖子类型发帖时出错

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“从网站发布”。当我尝试使用此插件从首页发布到“故事”时，我收到一些错误。

您也可以在这里尝试:http://www.teenbetween.relationshipsireland.com/your-family-life/accepting-the-decision/ - 您会在下图中找到一个链接，使用它。

文章已发布，但我收到错误。

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 函数期间不可用。调用该函数时，传入 $post_id 作为第一个参数。您还需要将 story.php 中的授权代码移至 save_details 函数中。

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