first: THANK YOU FOR THIS POST !!!
this was exactly what I needet. works like a charm.
on a restaurant/venue page I have child posts with ratings and I can display the total average rating. PERFECT.
I have a facebook like startpage, displaying new venue posts, with total rating.
this works fine.
than I also display new commtes/ratings for venues.
I can display the users rating, but not the total rating.
becaus the post is already the child.
I tryed
[rating-average id="$venue"]
but I know this can't work. it was just a good portion of hope 😀
how can I make it work ?
this is my function:
add_shortcode('rating-average', 'rating_average_func');
function rating_average_func()
{
$child_posts = types_child_posts('venue-rating');
$sum = 0;
$num = 0;
foreach ($child_posts as $child_post) {
if(isset($child_post->fields['rating-venue']))
{
$sum += $child_post->fields['rating-venue'];
$num ++;
}
}
$res = '';
if($num>0)
{
$res_10 = $sum/$num;
}
$res = $res_10/10;
return $res;
};
(don't worry about /10 .. I user for rating 10,20,30,40,50 istead of 1,2,3,4,5)
I hope you guys understand what I mean.
maybe for better help:
hidden link
so if someone can help me to figure out how to display the total average of the parent.. that would be so AWESOME 🙂
thank you all

OK, so implementing the custom fields and updating avg rating and total reviews on the post being reviewed itself instead of making queries each time was pretty easy thanks to Trigger + Luoyang's original code. Here's what you have to do:
1. Create a new field group called: Fields for Avg and Total Ratings (or whatever you want)
2. Add two number fields: "Average Rating" and "Total Ratings" . Save the fields and make sure you make them available for the post types you are reviewing.
3. I assume you have a CRED form for creating reviews. Each time this CRED form is submitted, it will automatically calculate and update the average rating and total ratings for the post being reviewed. In order to do so, add this to your functions.php. Remember to change the number in
if ($form_data['id']==7954
to your form number, and verify your custom field slugs and post type slugs. My post type uses 'review' instead of 'ratings':
//*Update Avg Ratings and Total # of Ratings after review submission
function update_post_ratings($post_id, $form_data)
{
// if a specific form, change ID to the CRED "Review" ID
if ($form_data['id']==7954)
{
//Get ID of Post Being Reviewed
$current_post_id = $form_data["container_id"];
$post = get_post( $current_post_id );
$args = array(
'post_type' => 'review',
'meta_key' => '_wpcf_belongs_' . $post->post_type . '_id',
'meta_value' => $post->ID,
);
$child_posts = get_posts($args);
$sum = 0;
$num = 0;
foreach ($child_posts as $child_post) {
$ratings = get_post_meta($child_post->ID, 'wpcf-rating', true);
if($ratings)
{
$sum += $ratings;
$num ++;
}
}
$average = 0;
if($num>0)
{
$average = $sum/$num;
}
$res = $average;
if($average==0) $res = 0;
if($average>0.001 && $average<0.5)$res = 0.5;
if($average>0.501 && $average<1) $res = 1;
if($average>1.001 && $average<1.5) $res = 1.5;
if($average>1.501 && $average<2) $res = 2;
if($average>2.001 && $average<2.5) $res = 2.5;
if($average>2.501 && $average<3) $res = 3;
if($average>3.001 && $average<3.5) $res = 3.5;
if($average>3.501 && $average<4) $res = 4;
if($average>4.001 && $average<4.5) $res = 4.5;
if($average>4.501 && $average<5) $res = 5;
update_post_meta( $current_post_id, 'wpcf-average-rating', $res );
update_post_meta( $current_post_id, 'wpcf-total-ratings', $num );
}
}
add_action('cred_save_data', 'update_post_ratings',10,2);
4. Now, instead of using the shortcodes created previously, you can use types shortcodes in your views/layouts/content editor to display avg rating and total ratings on your posts. For example:
[types field='total-ratings' format='FIELD_VALUE'][/types] Review(s)
You can see an example picture of what I got it to look like on the front end with the star ratings plugin I mentioned in my previous post.
5. For the few people using WPML, we have to edit this code to make the ratings sync between languages. I'm currently working on that, but I cannot make any promises!
I wanted to provide another way of implementing Schema on your listings. I know the OP had a restaurants directory, but for those with multiple categories, I have found a way to dynamically provide the correct Schema for any type of listing. It involves the use of a taxonomy custom term field, a taxonomy view, and knowledge of proper, specific Schema for various businesses, links of which will be provided.
Step 1. Find the proper Schema for your categories -
If your directory has multiple types of listings, you probably have a taxonomy for them like "Listings Categories". In this taxonomy, you have terms such as "Restaurants," "Cafes," "Bars," and so on. Instead of just using the general "LocalBusiness" Schema term for your listings, you should be as specific as possible. The link below is an excel spreadsheet of the best Schema term to use for various businesses. If you can't find a specific term, try checking Google: just search "Your Term" - Schema.
Link: hidden link
Step 2. Create a custom term field on your taxonomy and place the correct Schema term inside of each term's custom field.
It sounds confusing, but it's really easy. Go to your Toolset dashboard, then find "Term Fields". Add a new field group called "Schema Modifier," and attach it to the taxonomy you need it for. In my case, it is called "Listings Categories". Then you will add a single line field to this field group called "Schema String". See the screenshot below of what it will look like.
Step 3. Fill in the "Schema String" field on your taxonomy's terms with the correct Schema term you found in Step 1.
Only fill in the most specific ones (for example, if you have a parent term "Art&Entertainment", leave that alone. Instead, fill in the fields for the children, e.g. "Art Galleries", "Cinemas", etc.). See screenshot below.
Step 4. Create a taxonomy view and place the Schema script in there while using views shortcodes to populate the fields automatically.
OK, so we create a taxonomy view for our taxonomy, "Listings Categories", then we set Query Filter to return "Taxonomy is set by the page where this View is inserted", so it will only output results for terms that are attached to the listing where the view is placed. To be extra, extra safe, we should only output fields where "wpcf-schema-string is a string greater than '' ", meaning no fields for terms with blank fields will be output. See the screenshot for clarification.
One thing I must stress here is that you must tell Views to only query ONE value. If on your listings, you selected multiple terms which have the Schema field filled in, that will get output multiple times and will cause errors.
Next, we have to populate the view with Schema script. For this, I used the JSON-LD method, which is different from what the OP used. JSON-LD is now what Google recommends, and worked better for my setup. For a business, an example of this script is -
<script type="application/ld+json">
{
"@context": "<em><u>hidden link</u></em>",
"@type": "Museum",
"address": {
"@type": "PostalAddress",
"addressLocality": "Hangzhou",
"addressRegion": "Zhejiang",
"streetAddress": "浙江省杭州市滨江区滨文路548, Binjiang District",
"addressCountry": "CN"
},
"aggregateRating": {
"@type": "AggregateRating",
"ratingValue": "4",
"bestRating": "5",
"worstRating": "0.5",
"reviewCount": "5"
},
"name": "Zhejiang Museum of Traditional Chinese Medicine (浙江中医药博物馆)",
"image": "",
"openingHours": [
""
],
"telephone": "(+86) ",
"url": ""
}
</script>
So as you can see, I have even put my Total Ratings and Average Reviews fields inside of this, which is something Schema loves. This is the final output, but what do you need to put between <wpv-loop></wpv-loop>? The answer is below (and please do some research on Schema before deciding which fields you would like to implement as every site is different).
<wpv-loop>
<script type="application/ld+json">
{
"@context": "<em><u>hidden link</u></em>",
"@type": "[types termmeta='schema-string' output='raw'][/types]",
"@id": "[wpv-post-url]",
"address": {
"@type": "PostalAddress",
"addressLocality": "Business's City",
"addressRegion": "Business's State/ Province",
"streetAddress": "Business's Address, District/Town",
"addressCountry": "Business's Country"
},
[wpv-conditional if="( $(wpcf-total-ratings) gt '' )"]
"aggregateRating": {
"@type": "AggregateRating",
"ratingValue": "[types field='average-rating' format='FIELD_VALUE'][/types]",
"bestRating": "5",
"worstRating": "0.5",
"reviewCount": "[types field='total-ratings' format='FIELD_VALUE'][/types]"
},
[/wpv-conditional]
"name": "[wpv-post-title]",
"image": "[wpv-post-featured-image output='url']",
"openingHours": [
"[types field='listing-hours'][/types]"
],
"telephone": "[types field='listing-phone'][/types]",
"url": "[types field='listing-website' output='raw'][/types]"
}
</script>
</wpv-loop>
Right, so along with normal fields that I use for my listings, like phone, website, hours, etc., you can see that "aggregateRating" uses reviews shortcodes, and the custom term field we created in Step 2. goes in this string:
"@type": "[types termmeta='schema-string' output='raw'][/types]",
Please note that you will have to manually find the types shortcodes for your listings fields in another view because the plugin will not let you select them when adding a taxonomy view.
As a safeguard, if the schema-string for terms on a listing hasn't been set, you still need to output Schema, fortunately, Views let's us output something if nothing was found. In between the
[wpv-no-items-found][/wpv-no-items-found]
fields, you can use the exact same code as above, with the only exception that you set the Schema "@type" to LocalBusiness (or whatever is best for you).
Awesome, now all we need to do is...
Step 5. Place the taxonomy view in the layout or content template for your listings' SINGLE POSTS
This one is straightforward if you know how to use views. Place it anywhere in the loop. Since the only output is a script, it won't change the display of anything.
Lastly, you should verify that the script is working correctly. Use the Google structured data tester:
hidden link
And either copy + paste your page's source code (right click on page and 'view source code'), or just paste your URL if you have a live site. If you see the correct Schema terms with no errors, you've done well. See my last screenshot for what you should see. I've even implemented Schema into my reviews, so you will see those as well.
PS: Sorry if I've been bombarding everyone with email updates for new posts, but this thread will be a great resource for people building a directory site with Toolset. Any questions/ concerns/ feedback/ improvements are more than welcome.
