我在这里有点自吹自擂，但为了让在WordPress中编辑自定义元字段更容易，我编写了一个名为Custom Bulk/Quick Edit.

该插件不仅将自定义元添加到批量和快速编辑屏幕以进行实际编辑，还将其作为列添加到帖子类型列表中。

然后，如果使用中的主题或插件尚未启用帖子类型列的自定义元，您可以使用过滤器添加列。

在您的主题中functions.php 文件添加类似于以下内容的代码。

add_filter( \'manage_post_posts_columns\', \'my_manage_post_posts_columns\' );
function my_manage_post_posts_columns( $columns ) {
$columns[\'custom_stuff\'] = esc_html__( \'Custom Stuff Here\' );

return $columns;
}

add_filter( \'manage_news-room_posts_columns\', \'my_manage_newsroom_posts_columns\' );
function my_manage_newsroom_posts_columns( $columns ) {
$columns[\'wpcf-publication-author\'] = esc_html__( \'Publication Author\');
$columns[\'wpcf-newsroom-type\']      = esc_html__( \'News Room Type\');
$columns[\'_views_template\']         = esc_html__( \'Content Template\');

return $columns;
}

请注意，为了帮助进一步开发和支持，免费插件仅限于WordPress自己的内置帖子类型。如果您使用的是自定义帖子类型，则可以购买自定义批量/快速编辑高级版。

或者，欢迎您通过以下方式从插件中提取代码https://github.com/michael-cannon/custom-bulkquick-edit.

将此代码添加到functions.php 文件此代码用于自定义post类型明细表。根据需要更改帖子类型。
