[Resolved] How can I show hide child posts with a membership button tied to a userprofile?

I am trying to: implement an "Enroll" button that adds a course to a user profile, showing that the user is enrolled in the course. Being enrolled means that the user gets access to the lectures that are children of the course.

I visited this URL: I tried to create a form that sends a textfield to the user profile, but I can't find a way to prepopulate the field with the post-title (or any data of the post where the form is applied). I can't use a type-field shortcode in the form shortcode when it is applied in a post. Right?
Like this:

[cred_field field='course' post='user' value='[wpv-post-title]' urlparam='' readonly='true']

When used as above, it returns an empty value. I hide the form field btw. but I checked the code and it doesn't show.

I expected to see: I expected a form field populated with the title of the post.

Instead, I got: An empty value.

Is there perhaps an easier way to edit membership in context?

Dear thomas,

Are we talking about a CRED form for edit user?
If it is, the attribute value='[wpv-post-title]' won't work as you expected, this course field will display the user field value.

I suggest you create a cred_generic_field for it, then use CRED action hook cred_save_data to save the value into database, more help:
