[Resolved] auto fill child post title with parent title

I have created a CRED form that creates a child post, and I would like to automatically (and invisibly) fill the title of the child post with the same title as the parent post.

I saw a thread that suggested this :
[cred_field field="post_title" post="contactformulier" value="[wpv-post-title id='$parent']"]
But even if this works, it would show the title on the form (for the user to see), right?

I tried adapting some code I saw in another thread like this:

//Shortcode to get current page title as title of child post (for CRED form relationships)
add_shortcode('current-parent-title', 'current_parent_title_func');
function current_parent_title_func($atts, $content){
$queried_object = get_queried_object();
$title = get_the_title($queried_object);
return $title;
}

[cred_generic_field field="_wpcf_belongs_answer_title" type="hidden" class="" urlparam=""]
{
"required":0,
"validate_format":0,
"persist":1,
"default":"[current-parent-title]"
}
[/cred_generic_field]

But I'm not convinced this will work because the "_wpcf_belongs_answer_title" doesn't seem right.

My parent CPT is called TEST and my child CPT is called ANSWER.

Can you help?

Thanks!

Dear Elise,

In your case, I suggest you try one of below two options:
1) Use CSS codes to hide the post_title field which outputted from CRED shortcode:
[cred_field field="post_title" post="contactformulier" value="[wpv-post-title id='$parent']"]

2) If you need use cred_generic_field, then you will need setup custom PHP codes to save it as the post title, for example use CRED action hook:
cred_save_data

This hook allows doing a custom action when post data is saved to database.

The first option is so simple and elegant ... but there is still one problem (that I might not be able to fix?)

Because this is on a create-child-post form, I guess the post doesn't officially have a parent yet - so when I use the code from your #1 above, it returns the title of the PAGE that the Cred form is on, rather than the title of the PARENT of the child post.

Is there anything I can do about that?

Thanks!

In the CRED form for creating child post, you can use CRED shortcode [cred_post_parent get='title'] to get the parent post title, see our document:

section "Information about Parent Pages"
