How to Filter Posts by Author and Nicename

Learn how to filter posts by post type and author with the help of the JetSmartFilters Author Post Type Filter add-on.

Proceed to the page where you want to place the filter; it can be edited either with Gutenberg or Elementor. Select a widget corresponding to the filter you have created and add it to the page. In our case, we pick the Checkboxes Filter.

Type in the newly created filter title in the Select filter field and choose the filter provider in the This filter for drop-down list.

Customize other filter settings according to your needs.

This is it. The posts are now filtered by their author.

Filter by ‘user_nicename’

Another way to filter posts is by ‘user_nicename.’


Nicename is a specific version of the login, the base of which is the username entered during registration. The nicename is displayed in the slug when you go to the user page.

Thus, if the user indicates their name during registration without special characters, it will also be used as the nicename, but in lower case. So, if you use symbols in the login that cannot be used in the slug, they will not be displayed.

For example, if a user chooses a “[email protected]” email as a login, the name will look like this: “testtest-com”.

The main difference between filtering by author and filtering by nicename is where you can take the Value displayed in the Options List.

You can find this value by following the Users > All Users pathway and opening the user profile page. To open the page, push the “View” button that appears once you hover over the user.

The user nicename will be displayed in the slug of the URL.

After copying all the needed slugs, return to the filter editor and enter all the required Values and Labels.

As we apply a filter for the post type, you can use JetEngine Listing Grid as the provider.


In this instance, you can use the Inject alternative listing items feature. Read about it in the article dedicated to this topic.

For example, you can use similar settings as in the following picture.
