Sorting data in WordPress is generally done in the most basic of ways. You want to see all posts that are in a specific category, you go to and there you are. But if you want to see everything in the category ‘drinks’ with the tag ‘bourbon’ and the custom taxonomy of ‘ingredients’ and a value of ‘mint’ AND ‘simple syrup’ to get the recipe for a mint julep, then you have a pretty crazy complex query.

Enter FacetWP

FacetWP is a premium plugin that, for $79 a year, handles all that crazy sorting for you. And yes, it’s worth it.

FacetWP introduces advanced filtering to WordPress, which lets you do things like get that list of all drinks made with bourbon that include a simple syrup, in a dynamic way! It’s incredibly fast, since it’s using ajax and javascript, and as long as you have enough server memory to index all the data in the first place, it’s faster than reloading a new category page.


In order to be that fast, you do not get pretty URLs. Let’s say you have your drinks category at `’ and you want to list all those things. Your URL will look like this:

The realistic reason they don’t try to make it ‘pretty’ is that it would create a lot more rewrite rules than would be sustainable, if you have a lot of facets. The number of checks would slow your site down, and that would kind of suck.

Compatibility Notes

If you use CMB2 you’ll need FacetWP + CMB2.

If you use Genesis themes, there are two tricks. First, you’ll want to use the following function to add FacetWP’s CSS to your theme:

function YOURTHEMENAME_facetwp_class( $atts ) {
    $atts['class'] .= ' facetwp-template';
    return $atts;
add_filter( 'genesis_attr_content', 'YOURTHEMENAME_facetwp_class' );

Second, if you’re like me and you use a lot of custom loops, they may not behave as expected. If you call the loop multiple times on a page (which is bad behavior in the first place and I know it), FacetWP has a bit of trouble knowing what javascript to apply to what section. That should be expected, and once I cleaned it up, it worked great.

Should you use it?

If you have a lot of complex intersectional queries to sort through, yes.

If you need dynamic result updates, yes.

It works.

  1. Facetwp is indeed a great plugin.
    I have seen a number of sites use it for filtering of posts with a filter widget at the sidebar.
