Alphabetize thread list order in single forum

[Cyn]

This is all I can find related to sort field in that section of the code before the switch, and right after:

PHP Code:

// look at sorting options:
if (!isset($sortorder)) {
  $sortorder = "";
}
if (!isset($sortfield)) {
  $sortfield = "";
}

if ($sortorder!='asc') {
  $sqlsortorder='DESC';
  $order['desc']='selected';
} else {
  $sqlsortorder='';
  $order['asc']='selected';
}
switch ($sortfield) {
  case 'title':
  case 'lastpost':
  case 'replycount':
  case 'views':
  case 'postusername':
  case 'voteavg':
    break;


  default:
if($foruminfo[forumid]==163) $sortfield='title';
  else $sortfield='lastpost';
}


if ($sortfield=="voteavg" and !$foruminfo[allowratings]) {
  $sortfield="lastpost";
}

$sort = array();
$sort[$sortfield]='selected';
