I am trying to modify edit.html.tmpl so that it can
display the profile.realname as well as
profile.login_name both shown in the same drop down
box.I couldn't find syntax for templates.Can anyone
please help me.
Current code is as follows. I would like to
concatenate
profile.login_name to the selitem how to do that.I
tried so many combination of operators and failed.Any
help is greatly appreciated.
I don't get response in this forum.
[% PROCESS selectprofile selname => "assigned_to"
                         selitem => profile.realname
                         selvalues => profiles
                         xtra =>""
             %]
