Drupal 7获取下拉列表所选值

我有以下代码从数据库中创建下拉列表：

  foreach( $aPlayers as $player ){
   if( $_SESSION['player'] == $player->iPlayer ){
     $playerSelected = $player->iPlayer;
   }
   $key = $player->iPlayer;
   $value = ucfirst($player->sName);
   $playersList[$key] = $value;
  }
  $form['gestionvideos_player']['selectplayer'] = array(
   '#type' => 'select',
   '#options' => $playersList,
   '#default_value' => $playerSelected,
  );

但当我尝试提交表单并获取用户选择的值时：

function gestionvideos_players_form_submit($form, &$form_state){
   echo $form_state['values']['selectplayer'];
}

返回值不是所选的值

你有什么办法帮我吗

谢谢：）

返回值是多少？你也可以分享你的链接。返回值是数据库中默认的值，但不是下拉列表中选择的值。。。你想让我分享什么链接？
