Question

我有一个Wordpress自定义帖子类型“精选书籍”，它使用副标题来指定书籍的标题。例如：“特色书：饥饿游戏”

是否可以自动将帖子标题设为“精选书”？

我通过谷歌搜索找到了这段代码，但它不起作用（Wordpress后端返回空白页面/白屏死机）

代码中是否存在语法错误，或者这是不可能的？

function add_custom_title( $data, $postarr ) {
  if($data['post_type'] == 'featured-book') {
    if(empty($data['post_title'])) {
      $data['post_title'] = 'Featured Book';
    }
  }
  return $data;
}
add_filters('wp_insert_post_data', 'add_custom_title', 10, 2 );

Answer 1

你有一个错字：

add_filter( 'wp_insert_post_data', 'add_custom_title', 10, 2 );

Answer 2

add_filter（'wp_insert_post_data'，'add_custom_title'，10，2）; 此功能挂钩是否在发布帖子或发布更新时触发我有类似的脚本在发布帖子上插入帖子标题，但是我的问题是它也在更新帖子上执行此功能。如何挂钩功能仅在发布后才能运行，而不能在更新时运行

我的代码

add_filter( 'wp_insert_post_data' , 'modify_post_title' , '99', 2 );  
function modify_post_title( $data , $postarr ) {

// Check for the custom post type and it's status
// We only need to modify it when it's going to be published

$posts_status = ['publish'];
if( $data['post_type'] == 'matrimony' && in_array($data['post_status'], $posts_status)) {

    $count_posts = wp_count_posts('matrimony');
    $published_posts = $count_posts->publish;
    $pending_posts = $count_posts->pending;
    if ($published_posts == 0) {
        if ($pending_posts == 0) {
            $data['post_title'] = 'ACMB' . '-1';
            $data['post_name'] = sanitize_title($data['post_title']);
        }
        else{
            // Get the most recent post
            $newposts = array(
                'numberposts' => 1,
                'orderby' => 'post_date',
                'order' => 'DESC',
                'post_type' => 'matrimony',
                'post_status' => 'publish'
            );

            $last_post = wp_get_recent_posts($newposts);
            $last__post_title = $last_post['0']['post_title'];
            $number = preg_split('/[^[:alnum:]]+/', $last__post_title);
            $number = $number[1] + 1;

            // Save the title.
            $data['post_title'] = 'ACMB' . '-' . $number;
            $data['post_name'] = sanitize_title($data['post_title']);
        }
    } 
    else {

    // Get the most recent post
    $newposts = array(
                'numberposts' => 1,
                'orderby' => 'post_date',
                'order' => 'DESC',
                'post_type' => 'matrimony',
                'post_status' => 'publish'
            );

    $last_post = wp_get_recent_posts($newposts);
    $last__post_title = $last_post['0']['post_title'];
    $number = preg_split('/[^[:alnum:]]+/', $last__post_title);
    $number = $number[1] + 1;

    // Save the title.
    $data['post_title'] = 'ACMB' . '-' . $number;
    $data['post_name'] = sanitize_title($data['post_title']);


}
}
return $data;
}

设置Wordpress自定义帖子类型的默认标题？
