A WordPress plugin that addresses some of the common accessibility issues when using FacetWP
Uses JS to take the data-name from the facet wrapper and apply to selects for facet type of dropdown and pager.
The sort facet does not have a UI interface in the admin and doesn't have a data-name attribute. I modified this via the 'facetwp_sort_html' filter with a generic aria-label of 'sort by' In order to make this more flexible a filter for this aria label was created.
This can be implemented like this:
add_filter( 'a11y_fixes_for_fwp_sort_by_label', function( $label ){ return 'Text you want for filter'; } );
For the checkboxes - added role="group" to the wrapping div and added an aria-label as well.
FacetWP has a11y features that are added via JS. This is done by using a filter.
add_filter( 'facetwp_load_a11y', '__return_true' );
If this is enabled by the user, this plugin disables this with by running late on the filter.
add_filter( 'facetwp_load_a11y', [ $this, 'disable_fwp_a11y' ], 9999 );
There is a small probablitly that if the priority is higher than 9999 than this will require adjustment.
The FacetWP a11y fix used the placeholder as an aria-label. This plugin keeps that, but adds a fallback to use the name of the facet if the placeholder is empty.
