However, these object types don’t have user interface to enter custom fields. WordPress developers have to add manual code to make it work. And that takes quite a lot of time and effort, especially for complex fields such as file upload or date picker.

Meta Box provides a solid foundation for all the custom fields work, from building the user interface to handling the data.

Usage

Before adding custom fields to comments, it’s important to know how to create a meta box with Meta Box plugin first. The meta box and custom fields are creating by declaring an array of settings in PHP. By default, they’re custom fields for posts.

To make them custom fields for comments, simply add the following line to the meta box settings code in PHP:

'type' => 'comment',

And then, go to edit a comment in the WordPress admin area. The fields will appear as the above screenshot.

It’s important to note that MB Comment Meta works only in the back end. It does not add custom fields for comments in the front end.

Finally, to get values of comment fields and display them in the front end, please see this documentation. It uses the same helper function rwmb_meta to get the field value and display it.
