Drupal content type text value

Question

I've created a content type that contains a form. In this form, there is a textfield that i want to make only readable + a specific value on it (if user A is editing this form, he can write on all textfields except this textfield that will contains : user A)

In the other side, I've a custom module that deals with users, so I have users with users ID, usernames..ect the username is the text that I want to automatically set on the content types textfield

I can't show you any code because as I said, it's a content type

Any help is great

Answer 1

It sounds like you're looking for Field Permissions.

The Field Permissions module allows site administrators to set field-level permissions to edit, view and create fields on any entity.

Answer 2

If this field is only used by modules and its existence doesn't make any change in your user's life , then you can make this field hidden in form . you also can fill its data using rules easily .
