This is taken from /horde/whups/lib/Form/Ticket/Edit.php
See whole file for more context.

What happens here? We're viewing the code where you can give a comment
to a ticket. In whups, you can have template replies to choose from.

                case 'comment':
                    $cvar = &$this->addVariable(
                        _("Comment"), 'newcomment', 'longtext', false);

                    /* Form replies. */
                    try {
                        $replies = Whups::permissionsFilter(
                            $whups_driver->getReplies($type), 'reply');
                    } catch (Whups_Exception $e) {
                        $replies = array();
                    }


The code above fetches template replies from database (if any exist).
Now we want to show the dropdown with replies only if we have template
replies in database (the count of $replies is not 0 or false)

                    if (count($replies)) {
                        $params = array();
                        foreach ($replies as $key => $reply) {
                            $params[$key] = $reply['reply_name'];
                        }
                        $rvar = &$this->addVariable(
                            _("Form Reply:"), 'reply', 'enum', false,
false,
                             null, array($params, true));


We fill the params array and add a form reply line to the form which
contains these template replies.


$rvar->setAction(Horde_Form_Action::factory('reload'));
                        if ($vars->get('reply')) {
                            $reply = $vars->get('newcomment');
                            if (strlen($reply)) {
                                $reply .= "\n\n";
                            }
                            $reply .=
$replies[$vars->get('reply')]['reply_text'];
                            $vars->set('newcomment', $reply);
                            $vars->remove('reply');
                        }
                    }


This part attaches a reload action to selecting any of these fields.
When the user selects any form reply, the form is reloaded and the
answer textbox is prefilled with the template reply.


The rest of the code checks for permissions to set for a comment. It
is not important for your problem but worth reading.


                    /* Comment permissions. */
                    $groups =
$GLOBALS['injector']->getInstance('Horde_Group');
                    $mygroups =
$groups->listGroups($GLOBALS['registry']->getAuth());
                    if ($mygroups) {
                        foreach (array_keys($mygroups) as $gid) {
                            $grouplist[$gid] = $groups->getName($gid,
true);
                        }
                        asort($grouplist);
                        $grouplist = array(0 => _("This comment is
visible to everyone")) + $grouplist;
                        $this->addVariable(
                            _("Make this comment visible only to
members of a group?"), 'group',
                            'enum', false, false, null,
array($grouplist));
                    }
                    break;
