How to Add ACF Filters to WordPress Feeds: A Step-by-Step Guide

Use ACF field values to filter a WordPress feed, then design the results with the Query Loop block.

Learn how to enhance your Query Loop Block by using custom Advanced Custom Fields (ACF) with the Filter Query Block Pro plugin. This plugin allows seamless integration of ACF fields for precise content filtering, perfect for sites looking to organize content dynamically.


Step 1. Install and Activate Filter Query Block Pro

  • Download and install Filter Query Block Pro from the plugin website.
  • In your WordPress dashboard, go to Plugins > Add New, upload the plugin, and activate it.

Step 2. Add Filter Query Block Pro to Your Page/Post

  • In the Gutenberg editor, add the Filter Query Block Pro to the page or post where you want the filterable feed.

Step 3. Configure ACF Field Filters

  • In the block settings, click Add Filter and select relevant ACF fields (e.g., location, topic, date).
  • Choose display options like dropdowns or buttons.

Step 4. Customize the Query Loop Block Template

  • Inside the Filter Query Block, there is a Query Loop Block as a child block.
  • Customize the Query Loop to design how posts are displayed, such as showing titles, excerpts, or custom layouts.
  • If you already have a Query Loop Block, you just drag it into the Filter Query Block.

Step 5. Preview and Test

  • Use preview mode to check that filters and layouts work as expected.
  • Adjust filter and styling options if needed for the best user experience.

Check the values before adding filters

Create the ACF field group and populate the field on the post type used by the query. Use consistent stored values: labels, saved values and relationship IDs can differ by field type. Check the supported field types and settings for your installed Filter Query Block Pro version. Test each filter with search, pagination and a combination that returns no posts.

Frequently asked questions

Why does an ACF filter return no results?

Check the query’s post type, the field name, the stored values and whether the target posts actually contain those values. Also clear any other active search or filters while diagnosing.

Can I add search to the same feed?

Yes. Enable the plugin’s search control and test it together with the ACF filters; the Query Loop remains responsible for the article layout.
