Question

我知道这是一个愚蠢的问题，我知道我的代码有什么问题，但无法弄清楚错误是什么。

function saveEvent($event_id,$old_category_id,$old_site_id,$old_user_id,$old_name,$old_description,$old_standby_start,$old_standby_end,$old_standby_reason,$old_standby_conclusion,$category_id,$site_id,$user_id,$name,$description,$standby_start_date,$standby_start_time,$standby_end_date,$standby_end_time,$standby_reason,$standby_conclusion)
{
  $standby_start = $standby_start_date." ".$standby_start_time.":00";
  $standby_end = $standby_end_date." ".$standby_end_time.":00";

// create new pdo object
$pdo = dbConnect();

    $pdo->beginTransaction();

    $pdo->rollback();

    // display error message and datas
    echo 'Tout ne s\'est pas bien passé, voir les erreurs ci-dessous<br />';
    echo 'Erreur : '.$e->getMessage().'<br />';
    echo 'N° : '.$e->getCode();

    // exit the catch to avoid the next errors
    exit();
}
}

也许我是瞎子，也许这个错误来自别的东西，但我现在正在读我的代码一小时但仍然不明白问题出在哪里

在此行中缺少逗号（，）。由于哪个绑定变量不匹配。

 $req = $pdo->prepare("INSERT INTO t_events_changes ....
              Values (... :new_standby_start:old_standby_end, ... )");
                                           ^ here missing comma

将其更改为，

:new_standby_start,:old_standby_end,

无法解决此问题：参数号无效：绑定变量数不匹配
