添加时自动添加类别 post

Question

我正在为一个新闻网站使用 wordpress。 有一个名为 Headlines 的地方，带有以下 ACF 代码。将帖子添加到网站标题。

array (
                        'key' => 'field_53e3e2fc67dc4',
                        'label' => 'Headlines',

                        'wrapper' => array (

                                ),
                                'post_type' => array (
                                    0 => 'post',
                                ),
                                'taxonomy' => '',
                                'allow_null' => 0,
                                'multiple' => 0,
                                'return_format' => 'id',
                                'ui' => 1,
                            ),                               
                        ),

这会创建一个字段以将已添加的帖子添加到标题列表中。 现在我希望这些字段在我按下更新按钮时自动添加到类别 "xyz" 中。我不知道要编辑哪个文件。

您需要使用 save_post 操作，将此代码添加到您的 functions.php 更改猫 ID 机智您的猫 ID

function set_my_categories($post_ID){
  if(wp_is_post_autosave($post_ID) || wp_is_post_revision($post_ID)) {
  return $post_ID;
  }
  wp_set_post_categories( $post_ID, array(49,13) );
  }
  add_action('save_post', 'set_my_categories');
