Related Frequently Asked Questions

What should I do if my radio button filter isn't showing up?

If your radio button filter isn't appearing, ensure that both the WP Search Filters and Dynamic Listing widgets are enabled in The Plus Settings. Additionally, verify that you've correctly assigned the custom fields to your custom post types. If the custom fields are not properly linked, the filter won't function as intended.

What are the best practices for setting up custom fields with ACF?

When setting up custom fields with ACF, ensure you clearly define the field names and assign them to the correct custom post types. This organization helps maintain clarity and functionality. Additionally, always save changes after creating or modifying fields to ensure they are applied correctly.

How do I add values to my custom fields after creating them?

After creating custom fields in ACF, you need to navigate to your custom posts and manually add values to these fields. This step is crucial as the radio button filter relies on these values to function correctly and filter the posts based on user selection.

Does the WP Search Filters widget support filtering by multiple custom fields?

The WP Search Filters widget primarily supports filtering based on the custom fields you define. If you want to filter by multiple fields, you may need to set up additional radio button filters for each custom field. This allows users to narrow down their search results effectively based on various criteria.
