“@graph” wrapping error in Structured Data

Resolved Jonah

Hi guys,

It seems Facebook Microdata (Pixel usage) doesn’t allow structured product data being wrapped they way WooCommerce do. When having multiple structures present on a page (e.g. BreadcrumbList and Product), the nodes are being wrapped under the “@graph” node, according to the following code in class-wc-structured-data.php (row 91-95):
```
// Wrap the multiple values of each type inside a graph... Then add context to each type.
foreach ( $data as $type => $value ) {
  $data[ $type ] = count( $value ) > 1 ? array( '@graph' => $value ) : $value[0];
  $data[ $type ] = apply_filters( 'woocommerce_structured_data_context', array( '@context' => 'https://schema.org/' ), $data, $type, $value ) + $data[ $type ];
}
```
This isn’t recognized by the Facebook Microdata Debug Tool at all, but when I manually remove the wrapping and put the Product node directly on the root, it works just fine.

Anyone seen this before? Can the Product node be lifted one level using the woocommerce_structured_data_product filter perhaps?

Open to suggestions.

Thanks

I’ve checked the debug tool from Facebook, and it seems to be working fine with your site.

You can also try to use this Chrome extension created by Facebook will verify that your Facebook pixel is working properly.

If you’re still having issues with that, could you please share a copy of your site’s System Status? You can find it via WooCommerce > Status.

Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response.

Also, the woocommerce_structured_data_product controls the full set of data for the product, it passes an array and can be used to add/change values to your structured data.

What’s the priority of execution of this filter on your code?

I hope to hear from you soon! My very best!

Hi @chiape and thanks for your response.

That’s strange as I’m getting the following result on Facebook Microdata Debug Tool:

Priority of the filter hook is 10. But even with the hook inactivated/removed I still don’t get any results for JSON-LD using the Facebook Microdata Debugger.

Hi @jonaho

Just to clarify it a bit more, are you adding Schema through the YOAST SEO plugin?

I am asking this because I didn’t find any Schema on your site using the Google Structured Data testing tool

Can you double-check if everything is set as stated on their documentation?

https://developer.yoast.com/features/schema/plugins/woocommerce-seo/

You can also try different plugins for that searching for “WooCommerce Schema” on the plugins repo.

Additionally, I’d recommend checking if it isn’t been overwritten, by your theme or any other plugin.

The best way to determine this is to:

Temporarily switch your theme to Storefront
Disable all plugins except for WooCommerce
Try do add your Schema markups using a plugin or custom codes and check it again.

A staging site would be a good idea at this point. If your host doesn’t offer that option, we recommend WP Staging for quickly spinning up a new test site.

Let us know how it goes! Thanks

Hi @chiape,

The YOAST Schema and structured Data has been inactivated. The only Schema loaded with the page and site is the one provided from WooCommerce. This can also be seen by using the Schema Markup Validator:

https://validator.schema.org/#url=https%3A%2F%2Fsmrtlab.se%2Fproduct%2Fcap%2F%3Fv%3Df003c44deab6

We’ll do some more testing on our staging environment and deactivate plugins.

Thanks,
