Add support for Groups to SearchWP

functions.php

<?php

// SearchWP 4.
add_filter( 'searchwp\query\mods', function( $mods, $query ) {
	global $wpdb, $wp_query;

	if ( class_exists( 'Groups_Post_Access' ) ) {
		$mod = new \SearchWP\Mod();
		$mod->set_local_table( $wpdb->posts );
		$mod->on( 'ID', [ 'column' => 'id' ] );
		$mod->raw_where_sql( function( $runtime ) use ( $wpdb, $wp_query ) {
			return ' 1=1 ' . str_replace(
				$wpdb->posts . '.ID',
				"{$runtime->get_foreign_alias()}.id",
				Groups_Post_Access::posts_where( '', $wp_query )
			);
		} );
		$mods[] = $mod;
	}

	return $mods;
}, 20, 2 );

// SearchWP 3.
function my_searchwp_where( $where, $engine ) {
	global $wp_query;

	if ( class_exists( 'Groups_Post_Access' ) ) {
		$where .= ' ' . Groups_Post_Access::posts_where( '', $wp_query );
	}

	return $where;
}

add_filter( 'searchwp_where', 'my_searchwp_where', 10, 2 );

Thanks for this !
I got an error when trying to use it : Notice: Undefined property: wpdb::$query

Changed the code to :

function my_searchwp_where( $where, $engine ) { global $wp_query; if ( class_exists( 'Groups_Post_Access' ) ) { $where .= ' ' . Groups_Post_Access::posts_where( '', $wp_query ); } return $where; } add_filter( 'searchwp_where', 'my_searchwp_where', 10, 2 );

and now everything works fine !
