Before the new relationships functionality, I was able to create an intermediary post that linked two parent posts of different types (the former way of doing many-to-many). When creating the intermediary post, I retrieved the post id for both parents on cred_save_data and used these to auto generate content.
However, after updating to the new relationships API I am no longer able to access the parent post ids on cred_save_data.
The new form field is as follows...
[cred_field field='@events_appearances.parent' select_text='--- not set ---' class='form-control' output='bootstrap']
I have tried all of the following solutions to try to retrieve the parent post ID but none of them have worked...
// Get ID of Parent Event Selected in CRED Form
// $event_id = $_POST['_wpcf_belongs_events_id'];
$event_id = $_POST['@events_appearances.parent'];
// $event_id = toolset_get_related_post( $post_id, 'events_appearances' );
// $event_id = get_post_meta($post_id, '_wpcf_belongs_events_id', true);
// $event_id = toolset_get_parent_post_by_type( $post_id, 'event' );
error_log(print_r($event_id, true));
Note: the parent CPTS are 'Vessels' and 'Events', both of which have a one-to-many relationship with the Intermediary CPT 'Appearances'.
I do not want to use the new many to many relationships format for this particular relationship at the moment, I simply want to retrieve the parent post IDs on cred_save_data so that I can access them in php.
In a Post Form that manipulates the Child (Many Part) of a modern Relationship, you should be able to access the set (and saved) parent Posts in a cred_submit_complete() (or later) from the very Child Post manipulated, using the new relationships API:
https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/
In a one to many like you have, where you get the one (parent) post from a many(child) ends, you would use toolset_get_related_post().
https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/#toolset_get_related_post
$related_post_id = toolset_get_related_post($post_id, $relationship );
Like this in a full example:
add_action('cred_submit_complete', 'ts_update_post_field_with_parent_post_id',10,2);
function ts_update_post_field_with_parent_post_id($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==39)
{
$relationship = 'page-post';//Edit the exact slug of the relationship you want to target
$related_post_id = toolset_get_related_post($post_id, $relationship );//can be repeated to get another related post of other type
//Example of what to do with such data
update_post_meta($post_id, 'wpcf-numeric-single-value', $related_post_id);
//To debug:
//var_dump($whatever);die();
}
}
Hi Beda,
I have tried the solution you've given but it doesn't appear to be working.
I include my full code below for reference, can you see any obvious mistakes in how I'm getting the parent post IDs?

Check what $post_id (of the Form hook) gives you.
It should give you the Post ID of the Post you are manipulating with this Form, and hence, the CHILD post.
Then make sure to copy the releationships slug, and that must be a modern, not migrated, not old one to many relationship.
That slug goes to the variable deteremining the relationship.
Then, if that is correct, the code $related_post_id = toolset_get_related_post($post_id, $relationship );//can be repeated to get another related post of other type and it returns the ID of the connected post, unless there is no connected post.
I tested that locally, it may be on your install other code or plugins or a theme interferes, can you test this on a clean test copy?
It seems to me you are not receiveing the proper post id to start with.
Hi Beda,
Thanks for the prompt response, the post id comes through correctly though I now realise there is a difference between 'Migrated' and 'Modern'. The relationships in question are currently of the Migrated type so I will look into replacing these first then get back to you if the issue persists.
Hello,
Please update this thread if you still more assistance.
Hi there,
I am having the exact same problem. Parent Post Type "Site -> Child Post Type "Truck"
---
function save_siteId( $post_ID ) {
if ( get_post_type( $post_ID ) == 'truck' && isset( $GLOBALS['post'] ) ) {
// Get Site from RelatedItem
$truck_id = get_post( get_the_ID() ); // Get ID of current truck
$site_id = toolset_get_related_post( $truck_id, 'site-truck', 'parent' );
// return $site_id;
update_post_meta( $post_ID, 'wpcf-trucksite', $site_id );
}
}
add_action( 'save_post', 'save_siteId', 20, 2 );
----
This works, but only if the post is updated. For a new post, this does not work, it only writes "0" in my field "wpcf-trucksite".
