Filter WooCommerce products by any attribute

Read an address

Paste the address of any filtered shop page and the tool tells you what it asks for. Try changing a value, adding a second colour, or putting in a made-up parameter.

The parameters

• filter_color=red,blue — products with red or blue, if query_type_color=or (the default);
• query_type_color=and — the same values, but a product must match all of them;
• filter_stock_status=instock, min_price, max_price and rating_filter for the other filters;
• sw_cat, sw_tag and sw_brand for categories, tags and brands, which are the plugin’s own.

A form without JavaScript sends a value as filter_color[]=red. Siftwren reads that spelling too and turns it into the comma form when JavaScript is on.

Why use WooCommerce’s names

Because then the shop’s own query does the work. Siftwren applies nothing of its own to attributes, price, stock status or rating, and it touches only the main query of the shop page. A category, tag or brand that does not exist is ignored by the plugin, and an attribute value that WooCommerce does not know simply returns no products, as it would without us.
