[Waiting for user confirmation] Automatically generate post title based on a relationship

Hi,

I want to create post title based on a field from a relationship and a taxonomy.

The components would be the Post Title from the related post.

So I would like the title to be in the form of "Relationship Field - Taxonomy Value" (e.g., Design Reference 2022-23)

I can see how to access normal fields from the post, but I cannot seem to get the relationship field.

Any help would be greatly appreciated.

Hello. Thank you for contacting the Toolset support.

You can acess the relationship field value using the types field API:
- https://toolset.com/documentation/customizing-sites-using-php/functions/

For instance - if you have a parent custom field with slug "book-name" - you can get the value of the parent on child form as:

$parent_id = 999;
$parent_book_name = types_render_field( "book-name", array("item"=>$parent_id));

Where:
- Replace 999 with the original parent ID.

To get the parent post term:

      $parent_id = 111;  // adjust your parent post ID here
      $taxonomy_slug = 'book-type';
      $parent_terms = wp_get_object_terms( $parent_id ,$taxonomy_slug); 
  
 
        if(!empty($parent_terms)) {
  
               foreach($parent_terms as $parent_term) {
                 //// do whatever you want
            }
        }

Where:
- Replace 'book-type' with your original taxonomy slug.

Hi Minesh,

This is really helpful, and I can see how this can work.

However, this presupposes that there is a known $parent_id, but this would change from post to post. How can I get the $parent_id from the current post? I've been looking at the Programmer Documentation, but I can't seem to find this.

I have two post_types, called Awards ($post_type = 'award') and Award Recipients ($post_type = 'award-recipient'). 'award' has the name of the Award and various general information. The Award Recipient is the person that receives the award, so has name, year of award, etc. There is a (one to many) relationship between Award and Award Recipient.

We don't know the parent_id of the Award, as there may be many awards and many recipients. So, for the code you have shown me, I need a way to get the parent_id from the 'award'.

Is there a way to do this?

Many thanks for your help!

I would like to know - at what course of action you want to generate the post title automatically?

Are you using Toolset form? if yes - Can you please tell me on what page/post you added the Toolset post form?

*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.

I have set the next reply to private which means only you and I have access to it.

That is strange. Do you want to conntent the post while adding the post from frontend? If yes:
- Have you checked the Tooslet forms?
