CRED plugin provides an API, making it easy to customize your post or user forms. The API includes hooks (actions and filters) to accomplish specific tasks using PHP code.
When you ask for help or report issues, make sure to tell us all related information about your form and what you want to achieve.

Problem:
I want to add data to the title of the currently submitted post with Toolset Forms, the data should come from the parent (related) post of the currently submitted post.
How can I do that?
Solution:
There are 2 options, both need be hooked to a Forms API hook.
You can listen to the Form's inputs in $_POST and get the value from the select2 Field where you use to select the related post in Toolset Forms (if you have this field present).
Then, you can update the Post you are editing with that of that post by simply using the value returned by the $_POST of the Select2 Parent field, which is the ID of the parent post.
With that ID you can get any information about this post using the WordPress API and populate your post as well using the WordPress API.
The select2 for parent selectors in the $_POST will be available with something link `$_POST['@post-type_right-post-type_parent'];`
You can get it's precise value by dumping the $_POST in the Form, to use the precise slug of your relationship selector.
All these actions need to be hooked to cred_save_data(), to fire at the right moment when the Form saves it's data to the database.
The other approach is using the Toolset Relationships API hook toolset_get_related_post() to get the (one) related post to the currently edited one.
This should be done on a cred_submit_complete() Toolset Forms hook to ensure all data, inclusive relationships, are stored in the database already.
Then we can get the related Post ID, and again with that ID, we can get the post data using WordPress API.
From here on the process is the same as with the first approach.
Problem: I am trying to use the Forms API, but I'm having trouble getting the value of a custom field and the selected post parent.
Solution: Use the 'wpcf-' prefix to access the value of a Types custom field in the Form, and use the parent field name to access the ID of the parent post.
Problem: I have a custom field in my Form. The option values for this field correspond to taxonomy terms. I would like to use the cred_save_data hook to add the selected term to the post.
Solution:
You can use wp_set_object_terms to set a term in a post.
Problem:
I have a Post Relationship (O2M) where a Toolset Post Form creating new M-Posts offers a Parent Post Selector where the user can set the O-Post to which the new post will belong to.
I want to retrieve the value of that Select2 in $_POST and use it in a cred_save_data() to populate other items with it.
How to go about it?
Solution:
A Select2 Parent Post Field in a Toolset Form, assuming a relationship between pages and posts (O2M) can be retrieved with
1
$_POST["@post-page_parent"]
Note that the HTML input name of the Select2 will have a dot as in
1
@post-page.parent
But the $_POST will listen to the key with an underscore instead of dot, as in @post-page_parent
So you can get the proper name of the $_POST Select2 input with this process:
- either open the console and find the HTML input name, replace the dot with an underscore and use that
- or, simply var_dump() the $_POST in the Form and see the precise name of all and every $_POST items
