Demfilz Fields and Filters

Demfilz Fields and Filters does two jobs that belong together:

1. 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.
2. 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.
