Tell us what you are trying to do?
In the system I am designing with Toolset Types, I have these custom types
Tutors
Students
Matches

Tutor contains a number of fields about Tutors and also uses an item that is a taxonomy named "Tutor Status"
Student contains a number of fields about Students and also uses an item that is a taxonomy named "Student Status"
Matches is a child post type of Tutor and Student and contains information that ties a Tutor to a Student.

On my Add and Edit Match forms, I want to update the Student->Student Status and Tutor->Tutor Status values. From the documentation, I don't see how to access a taxonomy associated with a parent post. Can you point me to an explanation?

Is there any documentation that you are following?
I have not found any.

Is there a similar example that we can see?
No

What is the link to your site?
hidden link <- I can give you temporary access.

Hi, a CRED form is designed to only create or edit one post at a time. So there's not a straightforward way to modify a parent post's taxonomy terms when you create a child post. It's necessary to use the cred_save_data hook to programmatically modify a parent post using custom code with the native WordPress API wp_set_object_terms. We have information about the cred_save_data hook here:
https://toolset.com/documentation/programmer-reference/cred-api/#cred_save_data

WP's documentation for the wp_set_object_terms API:
https://codex.wordpress.org/Function_Reference/wp_set_object_terms

A basic example:

add_action('cred_save_data_12345', 'set_parent_tutor_term_from_child',100,2);

function set_parent_tutor_term_from_child($post_id, $form_data) {
  $taxonomy = 'tutor-status';
  $tag = array( 'tutor-term-slug' );
  $parent_id = get_post_meta($postid, '_wpcf_belongs_tutorslug_id', true);
  wp_set_object_terms( $parent_id, $tag, $taxonomy, true );
}

This will associate the term 'tutor-term-slug' from the taxonomy 'tutor-status' to the parent tutor of the post just created by CRED.Change 12345 to match your CRED form ID, change tutor-status to match your Tutor Status taxonomy slug, change tutor-term-slug to match the term slug you want to associate with the parent post, and change tutorslug to match your tutor post type slug.

You can reuse this code, with a few minor adjustments, for the student term as well. If you want to allow the user to select between multiple terms in the CRED form, it requires a bit more work because you must create the term select input, and capture that value from the form submission object.

Let me know if you have additional questions about this, and I can provide further assistance if necessary.

Thanks! I appreciate your detailed response and the example code.
