Comments Categories

Add categories for the post comments on your blog

Jesper van Engelen

Adding multiple categories in WordPress can be a real pain. When you want categories for every country in the world, it is a horrible job to fill out and submit the new category form hundreds of times, especially if you’re adding terms that have a hierarchy!
BulkPress makes this process much easier, by providing you with an easy-to-user interface to add categories (and terms of custom taxonomies) and pages/posts (and posts of custom post types) in bulk, giving you the option to specify a hierarchy in the added posts or terms.
BulkPress can spare you hours of your time, just try and find out for yourself!
<h4>More to come…</h4>
BulkPress will be updated with new functionalities very regularly. What to think of the following features coming to your WordPress installations soon…
<ul>
<li>Mass add users</li>
<li>Specify attributes for the pages you’re creating in bulk, such as the page template</li>
<li>Promoting multiple users to a different role in one go</li>
<li>Much, much more…</li>
</ul>
<h4>Feature requests</h4>
If you have any feature requests for this plugin to allow you to mass manage content more easily, just drop the suggestion in the forums!

BulkPress

It does what it says. "It just works". Would be be great if we could add categories or tags to each post but that's fine.

Tested with Wordpress 5.8 and it works like a charm.

FANTASTIC!!

Add posts, pages, categories and custom post types and taxonomy terms in bulk! Managing vast amounts of content made a walk in the park!
