Hooks and Filters

The WPify Woo Feeds plugin provides hooks and filters to customize feed generation and product data.

Feed Module Filters

wpify_woo_feeds_modules

Filter available feed modules.

apply_filters( 'wpify_woo_feeds_modules', array $modules );

Parameters:

• $modules (array) — Array of feed module instances

Example — remove Alza feed module:

/**
 * Remove Alza feed module
 *
 * @param array $modules Feed modules
 * @return array
 */
function my_remove_alza_feed( $modules ) {
    unset( $modules['feed_alza'] );

    return $modules;
}
add_filter( 'wpify_woo_feeds_modules', 'my_remove_alza_feed' );

wpify_woo_feeds_item_title

Filter product title in the feed.

apply_filters( 'wpify_woo_feeds_item_title', string $item_title, $product, $parent_product );

Parameters:

• $item_title (string) — Product title
• $product (object) — Product object
• $parent_product (object|null) — Parent product (for variations)

Example — append shop name to title:

/**
 * Append shop name to product title
 *
 * @param string $title   Product title
 * @param object $product Product
 * @return string
 */
function my_feed_item_title( $title, $product ) {
    return $title . ' | MyShop';
}
add_filter( 'wpify_woo_feeds_item_title', 'my_feed_item_title', 10, 2 );

wpify_woo_feeds_item_name

Filter product name in the feed (alternative to title).

apply_filters( 'wpify_woo_feeds_item_name', string $item_name, $product, $parent_product );

Parameters:

• $item_name (string) — Product name
• $product (object) — Product object
• $parent_product (object|null) — Parent product (for variations)

wpify_woo_feeds_dir_path

Filter the directory path where feed files are stored.

apply_filters( 'wpify_woo_feeds_dir_path', string $dir_path, string $feed_name, $feed );

Parameters:

• $dir_path (string) — Default directory path
• $feed_name (string) — Feed name
• $feed (object) — Feed instance

Per-Feed Filters

These filters use the feed name as prefix (e.g., google_merchants_feed, heureka_cz_feed, zbozi_feed, alza_feed).

{feed_name}_feed_product_ids

Filter which product IDs are included in the feed.

apply_filters( '{feed_name}_feed_product_ids', array $product_ids );

Example — exclude a specific product from Google Merchants feed:

/**
 * Exclude product from Google Merchants feed
 *
 * @param array $product_ids Product IDs
 * @return array
 */
function my_exclude_product_from_feed( $product_ids ) {
    return array_diff( $product_ids, [ 123 ] );
}
add_filter( 'google_merchants_feed_feed_product_ids', 'my_exclude_product_from_feed' );

{feed_name}_feed_data

Filter feed data before XML generation.

apply_filters( '{feed_name}_feed_data', array $data, string $feed_name );

Parameters:

• $data (array) — Feed data array
• $feed_name (string) — Feed name

{feed_name}_skip_product

Skip individual products from a feed.

apply_filters( '{feed_name}_skip_product', bool $skip, $product, string $feed_name );

Parameters:

• $skip (bool) — Whether to skip the product (default: false)
• $product (object) — Product object
• $feed_name (string) — Feed name

Example — skip products in hidden category:

/**
 * Skip products in "hidden" category from Google Merchants feed
 *
 * @param bool   $skip    Whether to skip
 * @param object $product Product
 * @return bool
 */
function my_skip_hidden_products( $skip, $product ) {
    if ( has_term( 'hidden', 'product_cat', $product->get_id() ) ) {
        return true;
    }

    return $skip;
}
add_filter( 'google_merchants_feed_skip_product', 'my_skip_hidden_products', 10, 2 );

{feed_name}_products_per_run

Override products per run for a specific feed.

apply_filters( '{feed_name}_products_per_run', int $products_per_run );

Example — reduce count for Google Merchants:

/**
 * Process only 50 products per run for Google Merchants
 *
 * @param int $count Products per run
 * @return int
 */
function my_feed_products_per_run( $count ) {
    return 50;
}
add_filter( 'google_merchants_feed_products_per_run', 'my_feed_products_per_run' );

{feed_name}_feed_filename

Filter the output feed file name.

apply_filters( '{feed_name}_feed_filename', string $filename, string $feed_name, $feed );

Parameters:

• $filename (string) — Default file name (e.g., heureka_1.xml)
• $feed_name (string) — Feed name
• $feed (object) — Feed instance

{feed_name}_get_product_ids_args

Filter WooCommerce query arguments for fetching product IDs.

apply_filters( '{feed_name}_get_product_ids_args', array $args );

Parameters:

• $args (array) — Arguments for wc_get_products() (limit, status, visibility, return)

Item Data Filters

Filter the data for individual items before they are written to the feed. Each feed has its own filter.

Example — add custom label to Google Merchants:

/**
 * Add custom label for products on sale
 *
 * @param array  $item    Feed item data
 * @param object $product Product
 * @return array
 */
function my_google_custom_label( $item, $product ) {
    if ( $product->is_on_sale() ) {
        $item['custom_label_0'] = 'sale';
    }

    return $item;
}
add_filter( 'wpify_woo_feeds_google_merchants_item_data', 'my_google_custom_label', 10, 2 );

Example — replace WEBP images with JPG in Heureka feed:

/**
 * Replace .webp extension with .jpg in Heureka feed image URLs
 *
 * @param array  $data    Feed item data
 * @param object $product Product
 * @return array
 */
function my_replace_webp_images( $data, $product ) {
    foreach ( $data as $key => &$value ) {
        if ( strpos( $key, 'IMGURL' ) !== false && is_array( $value ) && isset( $value['_cdata'] ) ) {
            $value['_cdata'] = preg_replace( '/\.webp$/i', '.jpg', $value['_cdata'] );
        }
    }

    return $data;
}
add_filter( 'wpify_woo_feeds_heureka_item_data', 'my_replace_webp_images', 10, 2 );

Available item data filters:

• wpify_woo_feeds_google_merchants_item_data
• wpify_woo_feeds_heureka_item_data
• wpify_woo_feeds_zbozi_item_data
• wpify_woo_feeds_alza_item_data
• heureka_availability_item_data

Note

The Heureka Availability feed uses non-standard hook names. The item data filter is heureka_availability_item_data (not prefixed with wpify_woo_feeds_) and the skip product filter is heureka_availability_feed_skip_product (not feed_heureka_availability_skip_product).

Actions

wpify_woo_feeds_cli_before_generate_feed

Triggered before WP-CLI feed generation starts.

do_action( 'wpify_woo_feeds_cli_before_generate_feed', array $args, array $assoc_args );

Parameters:

• $args (array) — WP-CLI positional arguments
• $assoc_args (array) — WP-CLI associative arguments
