Get aggregated rating for a post

You should use the same wpdiscuz_rating_schema hook and make the customization yourself. 

But how can I get the rating value on any page for a specific post? 

For example using a shortcode to display the rating of post with the id 123.

Because the schema filter only defines how the output schema in the source code will look like, right? 

Or to say it in other words: I want to use the ratingValue (within the schema)

Or to even more precise: I want the $avarage value from this function:

@zoker,

For example using a shortcode to display the rating of post with the id 123.

You can add the post_id attribute in the shortcode: 

[ wpdrating metakey="all" show-lable=true show-count=true show-average=true itemprop=true post_id="123" ] 

It'll display the average rating(included all rating fields) for the current post.  

Unfortunately I can't see the shortcode :/

Please check it again.  

@asti Thanks for the provided shortcode, but with that I only get something like this:

When you have a look at my site, you can see, that on the frontpage, some items have a rating (the 4.0 in the top left corner):

That's what I need. So I just need the value in decimal form, like 3.5 / 2.9 / 5.0 etc. 

And for that I don't that this shortcode is not suitable.
