How to add custom columns to the article list in the background of WordPress

By default, the background article list of WordPress only displays information such as article title, author, publishing time, etc. What should I do when I need to display customized information for some personalized requirements?

In fact, it is also very simple. WordPress provides developers with manage_posts_columns Hook. Through this hook, we can meet our needs.

Example: Add a list of modification times

 #Add article list function add_views_column($columns) { $columns ['post_modified ']=' modification time '; return $columns; } add_filter('manage_posts_columns' , 'add_views_column'); #Populate the article reading list with data function views_column_content($column_name, $post_id) { if ($column_name == 'post_modified') { echo  get_the_modified_time('Y-n-j H:i:s'); } } add_action('manage_posts_custom_column', 'views_column_content', 10, 2);

Add the above code to function.php Save it in
