I am getting a fatal error when trying to use WPSOLR_Events::WPSOLR_ACTION_POSTS_RESULTS:

Fatal error: Uncaught Error: Class ‘WPSOLR_Events’ not found

How do I reference and include the Events class?

You need to wait until WPSOLR is loaded.

See https://www.wpsolr.com/guide/actions-and-filters/:

Your declaration of the hook containing a reference to the php class WPSOLR_Events, it must be executed after the WPSOLR plugin is loaded.

For instance, in:

use wpsolr\core\classes\WPSOLR_Events;
add_action( ‘after_setup_theme’, function () {
… declare your WPSOLR actions or filters here
} );

or in

use wpsolr\core\classes\WPSOLR_Events;
add_action( ‘admin_init’, function () {
… declare your WPSOLR actions or filters here
} );

Ok, so the syntax should look something like this?

add_action( ‘after_setup_theme’, function () {
add_action(WPSOLR_Events::WPSOLR_ACTION_POSTS_RESULTS, ‘wpsolr_action_results’, 10, 1);
}

Looks like that, yes.

How would I modify the post results? I would like to replace a string in the result set.

Here is an example taken from /wp-content/plugins/wpsolr-pro/wpsolr/pro/extensions/geolocation/class-wpsolr-option-geolocation.php

/**
 * Add distance custom fields to the post results
 *
 * @param WPSOLR_Query $wpsolr_query
 * @param WPSOLR_AbstractResultsClient $results
 */
public function wpsolr_action_posts_results( WPSOLR_Query $wpsolr_query, WPSOLR_AbstractResultsClient $results ) {

 if ( empty( $wpsolr_query->posts ) || empty( $results ) ) {
	// No results: nothing to do.
	return;
 }

// Name of the field added to the post containing a list of distances
$field_distance_name = WPSOLR_Regexp::remove_string_at_the_end( self::GEOLOCATION_DISTANCE_FIELD_PREFIX, '_' );

foreach ( WPSOLR_Service_Container::getOption()->get_option_index_custom_fields( true ) as $custom_field_name ) {

 if ( self::_SOLR_DYNAMIC_TYPE_LATITUDE_LONGITUDE === WpSolrSchema::get_custom_field_solr_type( $custom_field_name ) ) {
 // Add geolocation fields to the fields

 $distance_field_name = $this->get_distance_field_name( $custom_field_name );

 foreach ( $results->get_results() as $document ) {

  if ( $document->$distance_field_name ) {

    foreach ( $wpsolr_query->posts as $post ) {

	if ( $post->ID === (int) $document->PID ) {

		if ( empty( $post->$field_distance_name ) ) {
		 $post->$field_distance_name = [];
		}

	$distance = is_array( $document->$distance_field_name ) ? ( $document->$distance_field_name )[0] : $document->$distance_field_name;

	array_push(
		$post->$field_distance_name,
	       (object) [
		'field_name'      => $custom_field_name,
		'distance'        => number_format( $distance, 2, '.', ' ' ),
		// distance formatted
		'distance_number' => $distance,
	        // distance not formatted
		]
		);
        }
      }
    }
  }
 }
}

return;
}

Thank you. How would I pass $wpsolr_query and $results? Could you add an example add_action passing those variables?

You have nothing to do. The parameters are passed by WordPress.
