Hook to modify content on a column on the edit.php (list of posts page)?
you can do this customisation by removing the core author column and replace it with a custom one. $post_type = “kea_activity”; add_filter(“manage_{$post_type}_posts_columns”, function ($posts_columns) { $posts_columns[“author_custom”] = “Author”; unset($posts_columns[“author”]); return $posts_columns; }); add_action(“manage_{$post_type}_posts_custom_column”, function ($column_name, $post_ID) { if (“author_custom” === $column_name) { $author = get_the_author(); echo esc_html($author) . ” <strong>information</strong>”; } }, 10, 2);
