FacetWP - index all posts demo

facetwp-index-all-posts-demo.php

/**
* Filter to customize FacetWP, should be pasted in FacetWP's "Custom Hooks" plugin
* 
* Made as a demo so I could figure out how FacetWP index filter works. 
* gives every post an entry in the "location_filter" facet
* 
*/
add_filter( 'facetwp_indexer_row_data', function( $rows, $params ) {
	if ( 'location_filter' == $params['facet']['name'] ) {
   				
		$new_row = $params['defaults'];
        $post_id = (int) $new_row['post_id'];
        $new_row['facet_value'] = $post_id; //id of the current existing post
        $new_row['facet_display_value'] = get_the_title( $post_id ); //title of post
        $rows[] = $new_row;
	
	}
	return $rows;
}, 10, 2 );

Not actually useful, just for helping me figure out how to use the facetwp_indexer_row_data filter
