Tell us what you are trying to do? We are having tours (products) and a CPT reviews. I like to get single fields using a short code to get different information - based on the field attribute.

Is there any documentation that you are following? https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/

Is there a similar example that we can see? Not yet...

But what I tried to do is the following code, but it not working:

function get_my_review($atts) {
  
  global $post;
  $str = '';
  $origin_id = $post->ID;
  $relationship_slug = 'my-tour-id';
  $field_value = get_post_meta($post->ID,'wpcf-'.$atts['field'],true);
  
  $results = toolset_get_related_posts ( 
        // get posts related to this one
        $origin_id, // get posts connected to this one
        $relationship_slug, // in this relationship
        array(
        	'query_by_role' => 'parent', // origin post role
        	'role_to_return' => 'child', // role of posts to return
        	'return' => 'post_id', // return array of IDs (post_id) or post objects (post_object)
        	'limit' => 999, // max number of results
        	'offset' => 0, // starting from
        	'args' => array(
                'meta_key'  => $field_value,
            ),
    	    )
        );
  
        if($atts['field']=='author-first-name' and !empty($field_value)) {
			$str .= $field_value;
		}
		return $str;
}
/* use on template [show_my_review field="author-first-name"] */
add_shortcode( 'show_my_review', 'get_my_review' );

What is the link to your site?

Hi Fred,

Thank you for getting in touch. You may not need to write a custom shortcode for this.

If it is a custom field value on a related item then you can use our [types field='my-field'][/types] shortcode with the item attribute.

See our documentation below on the item attribute.

Please let me know if this helps.
Thanks,
Shane

Dear Shane

I would love to have only [types field='my-field'][/types] - how do I add the attribute? like this:

[types field='my-field' attribute='@product-review.child'][/types]

Hi Fred,

Assuming the relationship slug information is correct then you should use "item" as the attribute like below.

[types field='my-field' item='@product-review.child'][/types]

Please let me know if this helps.
Thanks,
Shane
