[Resolved] Copy address field from parent CPT to address field of child CPT

This thread is resolved. Here is a description of the problem and solution.

Problem:

Customer wants that the address of the parent CPT aktivitaten get copied into the address field of the child CPT bewertung.
He saw an example using _wpcf_belongs_ but it is not working.

Solution:

Since Types version 3.x the usage of _wpcf_belongs_{parent-post-type-slug}_id has been discontinued. Now you need to use toolset_get_related_post when there can be only one result, e.g. you are starting with the ID of a child post and you want to get its parent (there can be only one parent, for a given relationship).

Or, you would use toolset_get_related_posts when there could be multiple results, e.g. you are starting with the ID of a parent post and you want to get all of the IDs of all of the child posts for some relationship.

Hello Toolset team,

I want to have the same functionality as it is described in this thread here: https://toolset.com/forums/topic/prefix-child-with-parent-data/

In my case I want that the address of the parent CPT aktivitaten will be copied into the address field of the child CPT bewertung. To make it quickly understandable: This is a rating system where users can rate activities and the aim is that the rating posts showing the address of the activity post by simply copying it.

So I took the code from the mentioned thread changed the fields which I thought are relevant and added this to my function.php. Unfortunately this does not work.

Can you please have a look on it and let me know where the error is?

Thank you and best wishes
Andreas

This is the code I used:

/**
* Copy parent address to child address
*/
add_action('cred_save_data', 'save_parent_fields_to_child_fields',10,2);
function save_parent_fields_to_child_fields($post_id, $form_data) {

// update this to match your CRED form ID
if ($form_data['id'] == 24)
{
$parent_id = $_POST['_wpcf_belongs_aktivitaten_id'];

$parent_first_name = get_post_meta($parent_id, 'wpcf-adresse', true);

// update the child custom fields
update_post_meta($post_id, 'wpcf-adresse_bewertungen', $parent_first_name );
}
}

and

I've tried to come up with a code based on your context. Please replace the slug of the relationship in the code bellow and see if it works for you:

<?php
/**
 * Copy parent address to child address
 */
add_action('cred_save_data', 'save_parent_fields_to_child_fields', 10, 2);
function save_parent_fields_to_child_fields($post_id, $form_data) {

    // update this to match your CRED form ID
    if ($form_data['id'] == 24) {

        // no longer valid
        // $parent_id = $_POST['_wpcf_belongs_aktivitaten_id'];

        // replace the slug
        $parent_id = toolset_get_related_post($post_id, 'slug-of-the-relationship', 'parent');

        $parent_address = get_post_meta($parent_id, 'wpcf-adresse', true);

        // update the child custom fields
        update_post_meta($post_id, 'wpcf-adresse_bewertungen', $parent_address);
    }
}

Thank you, please let us know.

Hi Mateus,

thank you very much for your quick answer. I adjusted the code but it does not work. My relevant key data for this topic is:

Parent CPT: aktivitaten
Relevant field slug of field-type ‘address’: adresse

Child CPT: bewertung
Relevant field slug of field-type ‘address’: adresse_bewertungen

And the code I added is:

/**
* Copy parent address to child address
*/
add_action('cred_save_data', 'save_parent_fields_to_child_fields', 10, 2);
function save_parent_fields_to_child_fields($post_id, $form_data) {

// update this to match your CRED form ID
if ($form_data['id'] == 24) {

// replace the slug
$parent_id = toolset_get_related_post($post_id, 'aktivitaten', 'parent');

$parent_address = get_post_meta($parent_id, 'wpcf-adresse', true);

// update the child custom fields
update_post_meta($post_id, 'wpcf-adresse_bewertungen', $parent_address);
}}

Can you see any issue?

Best wishes and good weekend
Andreas

Hey there,

I was able to fix it by changing a couple of things.

The slug of the relation in the code from 'bewertung' to 'aktivitat-bewertung'.

The hook we're adding this code from cred_save_data to cred_submit_complete.

The second change was necessary because when cred_save_data is called, the parent info has not been saved yet. This means that by that time if we try to retrieve the parent of that post we'll get 0 as result.

I tested it after changing both things and it seems to have the correct behavior now, please test it again.

Best,
