Overview
FacetWP uses a custom database table to store values for all facets. This filter lets you modify what gets saved to this table during the indexing process.
Parameters
- $params | array | An associative array of data to be indexed (see below)
- $class | object | The indexer class (e.g. use
$class->insert()to manually add rows)
// The keys correspond with columns in the `facetwp_index` table
$params = array(
'post_id' => 123,
'facet_name' => 'my_facet',
'facet_source' => 'tax/category',
'facet_value' => '45',
'facet_display_value' => 'My Test Category',
'term_id' => 0,
'parent_id' => 0,
'depth' => 0,
'variation_id' => 0
);
Usage
// Save date in "Jan 1, 2014" format
add_filter( 'facetwp_index_row', function( $params, $class ) {
if ( 'my_date' == $params['facet_name'] ) {
$raw_value = $params['facet_value'];
$params['facet_display_value'] = date( 'M j, Y', strtotime( $raw_value ) );
}
return $params;
}, 10, 2 );
Other Notes
facet_valueis used for the URL / permalinkfacet_display_valueis used as the label (front-end)- To bypass indexing for the current row, simply return false.
