[Resolved] Auto assign many-to-many relationship to a parent

Hello i'm using many to many relationships. I have post type "iscrizioni" child of "contatti" and "corsi". I'm using CRED to input.
Here is my example page:
hidden link

Clicking on tab "ISCRIZIONI" and then on button "AGGIUNGI ISCRIZIONE" we can add post type "iscrizioni".

We can choose correctly parent "corsi" and contatti.

I would auto assign to current contact, we don't need to specify again because we are already in contact tabs. In backend i could add a new "iscrizione" from "contatto" correctly, i have problem only with CRED.

It is possible?

Thanks

Hi, if you want to predefine values for a CRED field, you have 3 basic options:

1. Provide the value as a URL parameter. Link to the page containing the CRED form using the URL value to supply the correct parent ID, something like yoursite.com/cred-form-page?contatti=1234. Then update your parent contatti CRED field and add the urlparam attribute:

[cred_field field='_wpcf_belongs_contatti_id' post="iscrizioni" urlparam="contatti"]

This would predefine the contatti with ID 1234 as the parent of the new post.

2. Provide the value in the value attribute. You can use a hard-coded number or a shortcode in the value attribute to predefine the parent contatti ID:

[cred_field field='_wpcf_belongs_contatti_id' post="iscrizioni" value="1234"]

3. Write your own custom code with JavaScript and/or PHP. Note that there is no CRED JavaScript API, so the amount of support we can provide for custom JavaScript is fairly limited.

In all 3 cases, you can wrap the field in a hidden div if you want to hide the field from your Users:

<div style="display:none;">
[cred_field ...]
</div>

The documentation for CRED fields can be found here:

Hello and thanks for response. I think i explained bad myself. The value in not the same in every form, i would to get from parent "contatto".

I don't understand if I am doing wrong with post relationship logic.

If in backend i edit "contatto-jack" and add "iscrizione-425" is obviously assigned to jack.

I'm trying to do the same with cred

I think you explained very well. I believe I am able to understand what you want to accomplish. You would like to use a CRED form to create a child post ("iscrizione" post type) for a specific parent post ("contatto" post type). The parent contatto will not always be the same, it will be dynamic.

In your CRED form, there is a field that allows the user to select a parent contatti for the new iscrizione post. This field will look something like this when you create the form:

[cred_field field='_wpcf_belongs_contatti_id' post='iscrizioni' value='' class='form-control' output='bootstrap']

The "value" of this field will determine the parent contatti. To predefine a parent contatti post in the CRED form, you must use one of the 3 methods I described. You must use a URL parameter to capture the parent ID, or pass the parent contatti ID into the cred_field using the "value" attribute, or use custom code.

You must decide which of these 3 methods works best for your site.

Thanks Christian you are right i managed via shortcode ID (finally!)

Cred shortcode used:

[cred_field field='_wpcf_belongs_contatto_id' post='iscrizione' value='[wpv-post-id id="$contatto"]' class='form-control' output='bootstrap']

I would a couple of questions:
I undestood that for me would be better simply add repeating group fields to my "contatto" custom post

With toolset and cred what is better method (database point of view also)?
