Id in a selectList

[Gael034]

Hi!!

I've made a form with a selectlist. It looks like working correctly but when I submit the content, the column ID is alway '0'... I can not write the id from the item selected on the list.

Here the code:

<?php
$estacion = ff_getParam('ff_param_estacion', 0);
$rows = ff_select(
"select id, estacion from #__metro "
);
$flag = 0;
$list = '';
if (!is_null($rows))
foreach ($rows as $row)
if ($row->id==$estacion) {
$flag = 1;
$list .= "1;$row->estacion;$row->id\r\n";
} else
$list .= "0;$row->estacion;$row->id\r\n";

if ($flag) return $list;
return "1;Selecciona la estacion;''\r\n".$list;
?>

The #_metro's structur: id, estacion - I'm sur it's nothing but I can not see the problem. Can you help me??

Many thanks
