Adding non-standard data to the search index

FiboSearch is a powerful and highly customizable search solution for WooCommerce, enabling users to search for products by a variety of data such as descriptions, tags, categories, SKUs, and more. Its flexibility extends even further through the use of code snippets, allowing you to index and search additional data, including custom fields, alt attributes of images, vendor names, and more.

In addition to product-related data, FiboSearch also provides the ability to include non-standard data in the search index for posts, pages, custom post types, and taxonomies. This allows for a more tailored and comprehensive search experience across your entire site.

This document will guide you through the steps required to add non-standard data to the FiboSearch index, helping you take full advantage of the plugin’s customization capabilities.

Search product variations by custom fields

The “Search in custom fields” option in FiboSearch settings applies only to simple and variable products. To make product variations searchable by custom fields as well, you can use the following code:

function fibosearch_get_product_variations_custom_fields_values( $product ) {
	$keys       = array( '_ts_gtin', '_another_custom_field' );
	$variations = $product->getAvailableVariations();

	if ( empty( $variations ) ) {
		return '';
	}

	$custom_fields_values = array();
	foreach ( $variations as $variation ) {
		foreach ( $keys as $key ) {
			$value = get_post_meta( $variation['variation_id'], $key, true );
			if ( ! empty( $value ) ) {
				$custom_fields_values[] = $value;
			}
		}
	}

	return join( ' | ', $custom_fields_values );
}

add_filter( 'dgwt/wcas/indexer/items_row', function ( $row ) {
	if ( isset( $row['post_type'] ) ) {
		return $row;
	}
	$product = new DgoraWcas\Product( $row['ID'] );
	if ( ! $product->isValid() || ! $product->isType( 'variable' ) ) {
		return $row;
	}
	$row['variations_custom_fields'] = fibosearch_get_product_variations_custom_fields_values( $product );

	return $row;
} );

add_filter( 'dgwt/wcas/tnt/indexer/searchable/product_data', function ( $document, $product_id, $product ) {
	$document['variations_custom_fields'] = fibosearch_get_product_variations_custom_fields_values( $product );
	return $document;
}, 10, 3 );

		return $data;
	}

	if ( $onlyIDs ) {
		return $data;
	}

	foreach ( $data as $index => $row ) {
		$product   = wc_get_product( $row['ID'] );
		$image_ids = [];

		if ( ! empty( $product->get_image_id() ) ) {
			$image_ids[] = $product->get_image_id();
		}

		$gallery_ids = $product->get_gallery_image_ids();
		if ( ! empty( $gallery_ids ) ) {
			$image_ids = array_merge( $image_ids, $gallery_ids );
		}

		$data[ $index ]['image_alts'] = '';
		foreach ( $image_ids as $image ) {
			$alt = get_post_meta( $image, '_wp_attachment_image_alt', true );
			if ( ! empty( $alt ) ) {
				$data[ $index ]['image_alts'] .= ' ' . $alt;
			}
