绑定变量的数量与令牌的数量不匹配-MySQl

更好的标题可能是“我不会数数”：-(

这段代码怎么了？应该很明显，但我看不出来

if (isset($_GET['campaign_id']))
{
    ChromePhp::log('API: request to update existing campaign "' . $campaignTitle . '"');
    $sqlCommand = $pdo->prepare('UPDATE campaigns SET title=:title, description=:description, start_time=:start_time, end_time:end_time) WHERE (customer_id=:customer_id) AND (campaign_id=:campaign_id)');
    $sqlCommand->bindParam(':campaign_id', $_GET['campaign_id']);
}
else
{
    ChromePhp::log('API: request to add a new campaign "' . $campaignTitle . '"');
    $sqlCommand = $pdo->prepare('INSERT INTO campaigns (customer_id, title, description, start_time, end_time) VALUES(:customer_id, :title, :description, :start_time, :end_time)');
}

$sqlCommand->bindParam(':customer_id', $customerId);
$sqlCommand->bindParam(':title', $campaignTitle);
$sqlCommand->bindParam(':description', $campaignDescription);
$sqlCommand->bindParam(':start_time', $startTimeStamp);
$sqlCommand->bindParam(':end_time', $endTimeStamp);
$sqlResult = DatabaseCommand($sqlCommand);

浏览到

http://localhost/api/addCampaign.php?customer=1&title=t&description=d&startTimeStamp=1443313713&endTimeStamp=1443313713&campaign_id=5

给出

消息：SQLSTATE[HY093]：无效参数编号：绑定变量的数量与令牌的数量不匹配

浏览器的开发者控制台日志显示

API：更新现有活动“t”的请求

谁会让我摆脱痛苦，让我说“噢！”？

这条评论有点长。我不知道你为什么会收到这条消息，但你在

更新中有这段代码：

end_time:end_time

这应该是

end_time = :end_time

也许这会解决你的问题
