Hooks & Filters

WooCommerce Product Sync Pro has hooks and filters which can be used to modify it’s behavior. For example, you can do the following:

• Change product prices so that the other site has different prices
• Prevent syncing of a certain product
• Map one field to another

You can try the examples below with Code Snippets or add them to your theme’s functions.php file.

wps_product_fields

The filter is used to modify product data before it’s sent to the receiving site.

Example: increase product price by 10 %

<?php
add_filter( 'wps_product_fields', function( $product_fields, $product, $site ) {
  $site_url = 'example.com'; // change to your site URL, no https prefix is needed

  if ( strpos( strtolower( $site->get_url() ), $site_url ) !== false ) {
    $product_fields['regular_price'] *= 1.1; // increase by 10 %
  }

  return $product_fields;
}, 10, 3 );

Please note that this snippet can only be used in one-way syncing. If it’s applied to two-way syncing, price would increase by 10 % every time the product is updated.

woocommerce_rest_pre_insert_product_object

The filter is used to modify product data before it’s saved on the receiving website.

Example: save additional meta data

<?php
add_filter( 'woocommerce_rest_pre_insert_product_object', function( $product, $request, $creating ) {
  update_post_meta( $product->get_id(), '_is_synced', true );

  return $product;
}, 10, 3 );

wps_should_sync_to_site

The filter is used to determine whether or not the product should be synced to a particular site. Applies when a product has been edited and when running the Push All tool.

Example: only sync if the product is published and the site ID is 50

<?php
add_filter( 'wps_should_sync_to_site', function( $should_sync, $product_id, $variation_id, $site_id ) {
	// Note that if the product is variation, $product_id will be the parent ID
	// and $variation_id the original product ID of the variation
	$product = wc_get_product( $product_id );

	if ( $product && $site_id == 50 && $product->get_status( 'edit' ) == 'publish' ) {
 		return true;
	}

	return false;
}, 10, 4 );

Tip! You can find the site ID by hovering over the site in the settings:

woo_product_sync_should_sync

The filter is used to determine whether or not the product should be synced when a product has been edited. Note! This doesn’t apply to Push All tool.

Example: only sync if the product has the category with the slug acme

<?php
add_filter( 'woo_product_sync_should_sync', function( $should_sync, $product ) {
	$slug = 'acme';

	// Get product categories
	$cat_slugs = wp_get_post_terms( $product->get_id(), 'product_cat', [
		'hide_empty' => false,
		'fields' => 'slugs',
	] );

	// Stop syncing if the product doesn't have the category with the slug "acme"
	if ( ! in_array( $slug, $cat_slugs, true ) ) {
		return false;
	}

	return $should_sync;
}, 10, 2 );
