Overview

Modify the array of values (for a specific facet) before each is passed through the facetwp_index_row hook and saved into FacetWP’s index table.

Parameters

  • $rows | array | An array of associative arrays. The elements of each associative array corresponds to columns in the facetwp_index table.
  • $params | array | Extra helper data (see below)
$params = [
    'defaults' => [
        'post_id'               => 123,
        'facet_name'            => 'facet_1',
        'facet_source'          => 'tax/category',
        'facet_value'           => '',
        'facet_display_value'   => '',
        'term_id'               => 0,
        'parent_id'             => 0,
        'depth'                 => 0,
        'variation_id'          => 0,
    ],
    'facet' => [
        'label'     => 'Facet 1',
        'name'      => 'facet_1',
        'type'      => 'checkboxes',
        'source'    => 'tax/category',
        // ...
    ]
];

Usage

Force FacetWP to index the value “Matt” into the first_name facet for every post:

add_filter( 'facetwp_indexer_row_data', function( $rows, $params ) {
    if ( 'first_name' == $params['facet']['name'] ) {
        $new_row = $params['defaults'];
        $new_row['facet_value'] = 'matt';
        $new_row['facet_display_value'] = 'Matt';
        $rows[] = $new_row;
    }
    return $rows;
}, 10, 2 );
