将自定义字段值复制到帖子标题

我使用了找到的代码here. 但是，在打开帖子并通过后端和前端点击更新按钮之前，这不会更新标题字段。我尝试用“edit\\u post”、“publish\\u Artister”和“wp\\u insert\\u post\\u data”更改“save post”挂钩，但仍然得到相同的结果。下面是我在使用“wp\\u insert\\u post\\u data”挂钩时使用的代码。

add_filter( \'wp_insert_post_data\' , \'modify_post_title\' , \'99\', 2 ); // Grabs the inserted post data so you can modify it.

function modify_post_title( $data )
{
  if($data[\'post_type\'] == \'artist\' && isset($_POST[\'artist_name\'])) { // The custom field
    $ArtistName = $_POST[\'artist_name\'];
    $data[\'post_title\'] =  $ArtistName ; //Updates the post title to your new title.
  }
  return $data; // Returns the modified data.
}

add_filter( \'wp_insert_post_data\' , \'modify_post_title\' , \'99\', 2 ); // Grabs the inserted post data so you can modify it. function modify_post_title( $data ) { if($data[\'post_type\'] == \'artist\' && isset($_POST[\'acf\'][\'field_573676a95d920\'])) { // If the actual field name of the rating date is different, you\'ll have to update this. $ArtistName = $_POST[\'acf\'][\'field_573676a95d920\']; $data[\'post_title\'] = $ArtistName ; //Updates the post title to your new title. } return $data; // Returns the modified data. } //Save ACF field as post_title for front-end add_action(\'acf/save_post\', \'change_artist_title_frontend\'); function change_artist_title_frontend($post_id) { global $_POST; if(\'artist\'== get_post_type()) { $post_custom_title = $_POST[\'acf\'][\'field_573676a95d920\']; $my_post = array(); $my_post[\'ID\'] = $post_id; $my_post[\'post_title\'] = $post_custom_title; remove_action(\'acf/save_post\', \'change_artist_title_frontend\'); wp_update_post( $my_post ); add_action(\'acf/save_post\', \'change_artist_title_frontend\'); } }

如何在Functions.php中链接style.css

我是WordPress的新手；我刚开始学习WordPress。我想把风格联系起来。函数中的css。php，但我无法解决这里可能存在的问题。谁能给我指出正确的方向吗？指数php<?php get_header(); ?> <?php if ( have_posts() ) { while ( have_posts() ) { the_post();
