Able to lock the field after populating?

Just what I was wondering, too.
Subscribing.

Same here. Subscribing.

I think the issue is out of the scope of this module but here is how this could be solved. First create a module which implement hook_form_alter. In this hook you can add a property "#disabled" to a form element to make it uneditable but still visible.

As a side note, this should not be used as some kind of security check. The url is really too vulnerable for this.

hook_form_alter: http://api.drupal.org/api/drupal/modules--system--system.api.php/functio...
forms_api_ref: http://api.drupal.org/api/drupal/developer--topics--forms_api_reference....

Is there an easier way for newbies?

This is somewhat related to #252053: Allow admins to hide prepopulated fields which anticipated not displaying the now "locked" field. Would your use case call for displaying the field without allowing the value to be changed on submission?

Hi

Ideally it would be possible to choose between prefilling and displaying as normal and editable, display the field but as read-only, or totally hide it. You knew the answer was going to be the worst case scenario, yes ?

Thanks for a great module.

I have written a patch that solves this and other problems, you are welcome to test it and provide your feedback if you can. It applies to 7.x-2.x branch.
You can find it attached to this issue:
#1489526: Improve prepopulate behavior

I'm using this module with entity reference on user names. I would like to lock the field as I don't want users to change the referenced usernames.

I wanted to hide title when it is prepopulated

I modified the prepopulate module like this

from:
       $form['#value'] = $requestslice ;

to

       $form['#value'] = $requestslice ;
       if ($form['#name'] == 'title'){
       	$form['#theme'] = 'hidden'; 
       }	

It works for me :)

Closing D6 issues as it's no longer supported.
