Descrición
Demfilz Fields and Filters does two jobs that belong together:
- Custom fields – define your own fields (text, number, select, radio, checkbox, date, URL, text area) and attach them to pages, posts, products or any public post type. Editors fill them in from a clean meta box on the edit screen.
- Front-end filters – drop the
[dfaf_filters]shortcode on any page to show a filter form plus a results grid. Visitors can filter by your custom fields, by tags, categories or any taxonomy, by WooCommerce global attributes (pa_*) and even by custom per-product attributes.
Filtering features
- Filter by any filterable custom field: choice dropdowns, multi-select checkbox lists, numeric min/max ranges, date ranges, yes/no toggles and keyword matching.
- Filter by any public taxonomy: tags, categories, product categories, product tags and WooCommerce global attributes.
- Filter by custom (per-product) WooCommerce attributes – the plugin indexes them into fast, queryable meta on every product save.
- Optional keyword search box and sort dropdown (newest, title, price for products).
- Paginated, responsive results grid (1-4 columns) with thumbnail, title, price and excerpt.
- Split mode: place the filter form on one page and point it at another page or your shop archive.
- Optional archive integration: apply active filters to blog, category, tag and shop archive pages.
- Shortcode builder in the admin so you never have to remember parameters.
Works with or without WooCommerce
WooCommerce is optional. Without it you can still define fields for posts and pages and filter them. With WooCommerce active, product support, price sorting and attribute filters light up automatically.
For developers
Field types live in a registry that the plugin itself uses for every built-in type. Register additional types through the dfaf_field_types filter, adjust queries with dfaf_query_args, decorate option labels with dfaf_option_label and customise result cards with dfaf_result_card_html.
Pro version
Everything above is free and fully functional. For sites that want more, Fields and Filters Pro is a separate add-on plugin ($19.95 per year) that adds:
- Instant AJAX filtering – results update as visitors change filters, no page reload, shareable URLs.
- Live result counts on every filter option.
- Colour swatch field type with visual swatch filter controls.
- Star rating field type with “and up” filtering.
- Pill-style filter controls.
External services
This plugin does not connect to any external service. No data leaves your site.

Preguntas frecuentes
-
How do I filter by WooCommerce global attributes?
-
Global attributes are taxonomies named pa_something. Add them to the shortcode, for example:
[dfaf_filters post_type="product" taxonomies="pa_colour,pa_size"]. -
How do I filter by custom (per-product) attributes?
-
Use the attributes parameter, for example:
[dfaf_filters post_type="product" attributes="material"]. The plugin indexes custom attribute values automatically when a product is saved; run Rebuild attribute index in Settings to index products that existed before the plugin was installed. -
Can visitors pick more than one value?
-
Yes. List the field keys or taxonomies in the multi parameter and they render as checkbox lists, for example:
[dfaf_filters post_type="product" taxonomies="pa_colour" multi="pa_colour"]. -
Yes. Use
[dfaf_filters post_type="product" form_only="1" action="/shop/"]for the form, then enable Archive filtering in Settings so the shop archive applies the filters. -
Does it slow my site down?
-
No. Values are stored as normal post meta and queried with standard meta and taxonomy queries. Custom product attributes are pre-indexed on save specifically so filtering never has to parse serialized data.
-
Where is the data stored?
-
Field definitions are a single option; values are post meta prefixed with dfaf. On uninstall the plugin removes its options, and also the post meta if you opted in on the Settings page.
-
Is there a Pro version?
-
Yes. Fields and Filters Pro is a separate add-on plugin ($19.95 per year) that adds instant AJAX filtering, live result counts on filter options, colour swatch and star rating field types, and pill-style controls. See https://demfilz.com/fields-and-filters. The free plugin is complete on its own and never locks features.
