Passing custom data to a user tag?

Question

Attempting to customize the list of users displayed based upon a custom field in a channel entry.

{exp:channel:entries channel="messages"}
  {exp:user:users group_id="{member_groups backspace="1"}{option_name}|{/member_groups}"}
    {email} - {group_id}
  {/exp:user:users}
{/exp:channel:entries}

The 'member_groups' custom field will output the chosen groups in this format...

group_id="7|8|9"

No matter what, I always get the logged in super admin account as a result. Is this possible with User or do I need to use a query here?

Would really prefer to not have to use an embed since I also need to this to work for sending email notifications when a new entry is posted to the messages channel.

Thanks!

Pretty sure this will not work unless you use an embed. That said, I am not sure why using an embed would stop email notifications from working (though I do not know how and what you intend on setting that up with). I am also assuming {member_groups} is a custom channel field?

Main template:

{exp:channel:entries channel="messages"}
  {embed="path_to/embed" member_groups="{member_groups backspace="1"}{option_name}|{/member_groups}"}
{/exp:channel:entries}

Embedded template:

  {exp:user:users group_id="{embed:member_groups}"}
    {email} - {group_id}
  {/exp:user:users}
