在数据库中添加值的PHP查询失败

我收到以下错误消息：

警告：PDOStatement:：execute（）：SQLSTATE[HY093]：无效参数编号：绑定变量的数量与中的令牌数量不匹配

我仔细检查了我所有的代码，似乎我有正确数量的变量和正确的名称：

    # Query to get the variable from the form (different page)
    $name = htmlspecialchars($_POST['name']);
    $description = htmlspecialchars($_POST['description']);
    $region = htmlspecialchars($_POST['region']);
    $country = htmlspecialchars($_POST['country']);
    $market = htmlspecialchars($_POST['market']);
    $strategy = htmlspecialchars($_POST['strategy']);
    $gate   =  htmlspecialchars($_POST['gate']);
    $priority = htmlspecialchars($_POST['priority']);
    $owner = htmlspecialchars($_POST['owner']);

所有变量都有一个值，并且都是正确的

我原以为你需要这样说：

$add = $bdd -> prepare('INSERT INTO project(name, description, region_id, country_id, market_id, strategy_id, gate_id, priority_id, owner) VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?)');

您似乎忘记在

owner

中添加冒号。它必须是

：所有者

您有一个印刷错误。在prepare语句的

正如警告所说-绑定变量的数量与令牌的数量不匹配。将
'：'
放在
'owner'
之前。您的声明必须是：

        (name, description, region_id, country_id, market_id, strategy_id, gate_id, priority_id, owner)

我认为这是键入错误-将“owner”替换为：“owner”。这就是问题所在。非常感谢。我认为这是键入错误-将“owner”替换为：“owner”。这就是问题所在。非常感谢。OP正在使用PDO而不是Mysqli扩展。你的回答对我来说很好。我没有太多的时间来写一个正确的答案，也没有看起来太难我的fopa.OP使用的是PDO而不是Mysqli扩展。你的回答对我来说很好。我没有太多的时间来写一个正确的答案，也没有看起来太难我的fopa很好。@CorentinCanet很乐意帮忙：）@CorentinCanet很乐意帮忙：）
