Display checklist in block instead of user profile

global $user;
module_load_include('inc', 'checklist', 'includes/checklist.pages');
print checklist_main_page($user, FALSE);

Just looked at the actual code. Here's a better idea:

global $user;
$lists = _checklist_get_user_lists($user, TRUE);
return theme('checklist_lists', array('lists' => $lists, 'account' => $user));

worked fine for me. I tested with 1 user instance.

Sorry to dig up an old thread but where exactly should I post this php code? In my themes template or in the module folder etc? (I am a drupal newbie)

This code was put into a block using the PHP filter (although it's not recommended to have this module turned on). You could also put this in a template file that is specific for the block.

You could also write a small module that implements the block hooks to accomplish this as well.

Thanks the code from post #3 worked for me, for some reason the code in #7 doesn't.
