Add a field into aircraft form

[a786013819]

I want to add "Airlines" into the aircraft form,and I could enter airlines for the aircraft when aircrafts are added/edited

So I have edited admin/templates/ops_aircraftform.tpl , admin/modules/Operations/Operations.php and core/common/Operationsdata.class.php,I also insert a new field in the database,and the new field display on the form successfully,but it's still write "1" into database

I added follow codes in the ops_aircraftform.tpl

<dt>* Airlines</dt>
<dd><input name="whos" type="text" value="<?php echo $aircraft->airlines; ?>" /></dd>

here is the codes I added in the Operations.php

$data = array(
'airlines'=>$this->post>airlines,//here
'icao'=>$this->post->icao,
'name'=>$this->post->name,
'fullname'=>$this->post->fullname,

and the Operationsdata.class.php

public static function addAircaft($data)
{
$data['airlines'] = DB::escape(strtoupper($data['whos']));
$data['icao'] = DB::escape(strtoupper($data['icao']));
...........
$sql = "INSERT INTO ".TABLE_PREFIX."aircraft (`airlines`,
 `icao`, `name`, `fullname`, `registration`, `downloadlink`,
 `imagelink`, `range`, `weight`, `cruise`,
 `maxpax`, `maxcargo`, `minrank`, `ranklevel`, `enabled`)
VALUES (
 '{$data['airlines']}','{$data['icao']}', '{$data['name']}', '{$data['fullname']}', '{$data['registration']}',
 '{$data['downloadlink']}', '{$data['imagelink']}', '{$data['range']}', '{$data['weight']}',
 '{$data['cruise']}', '{$data['maxpax']}', '{$data['maxcargo']}', {$data['minrank']},
 {$rank_level}, {$data['enabled']})";
..........

The part of edit aircraft is omitted

What should I do now?

I am sorry for my poor English

Thanks a lot

Hey I noticed one error...

$data['airlines'] = DB::escape(strtoupper($data['whos']));

Should this be...

$data['airlines'] = DB::escape(strtoupper($data['airlines']));

That's what I'm seeing...
