Add aggregateRating

Yes indeed, so you aren’t forced to hack the plugin in any way, you can do this:

add_filter( 'schema_wp_types', 'schema_wp_new_add_schema_type_7623456' );
/**
 * Add New type to Schema Types options
 *
 * @since 1.0
 */
function schema_wp_new_add_schema_type_7623456( $options ) {
	
	// Change 'NewType' to the actual schema.org type you want to add
	// Example: Event, Product, JobPosting, ...etc.
	$options['NewType'] =  array ( 
					'label' => __('NewType'),
					'value'	=> 'NewType'
				);	
	return $options;
}

Here is a link to the code gist.

But, it’s not as simple as adding just the new type, you will have add other properties as well to finally output a valid schema markup.

I suggest you look at the free Schema Review plugin, it will give you an idea of how you can achieve this by walking through its code.

Thank you for the answer!

However noo, the idea is to keep exactly the same type and just extend it with the rating.
As you can see the generic Article itself allows a sequence of options, one of those is aggregateRating:
https://schema.org/Article

So instead of the Article Type, I just want to use the options of the meta box.
Even better would be to just point a meta key without the need of an input.
This is the option I mean:

Do you think is this possible? Or otherwise use an hook in the same way to extend the object for Article – Type General?

Thank you in advance!

Yes of course, you can keep the same type and extend it with rating or reviews, so yes this is absolutely possible.

However, in your code example, I see you’ve chosen type AggregateRating, which has a “reviewCount“, which leaded me to think you will need to introduce a new schema.org type for it. I am not sure if this is what you want to do since the aggregate rating should have real user reviews published on the page.

You may look at using “reviewRating” instead of “AggregateRating” in case the latest doesn’t work, or gives you errors.

I hope this was useful.

Yeah I agree would make no sense a rating without an actual review, but unfortunately the request is to stick just to votes, which is something already online in another CMS.

I’ve been digging more into the snippets of code to alter the plugin without hack it and I found probably what I need, since match with the same place I’m writing the code.

A second part of the code is already written in another plugin where AJAX the rating is handled, with final meta data update, so it will synchronize with the whole project.

I’ll give a try and let you know, thank you for the support, snippet and plugin ??

Fantastic!

Let me know if you see a need for additional filters in the core code. I will be glad to add them in the Schema plugin to make things easier.

Perfect all solved without hack!
Thank you for the support ??

Glad to hear that ??
