我正在尝试使用带有数组形式参数的简单MySQL插入查询。它一直告诉我参数的数量是错误的。我尝试了以下内容,都产生了同样的错误:
$stmt3 = $link->prepare('INSERT INTO messages VALUES(null, :room, :name, :message, :time, :color)');
$stmt3->execute(array(':room' => $Clean['room'],':name' => $Clean['name'],':message' => $Clean['message'],':time' => $time,':color:' => $Clean['color']));
和
$stmt3 = $link->prepare('INSERT INTO messages VALUES(:null, :room, :name, :message, :time, :color)');
$stmt3->execute(array(':null' => null, ':room' => $Clean['room'],':name' => $Clean['name'],':message' => $Clean['message'],':time' => $time,':color:' => $Clean['color']));
以及专门声明列以避免空插入:
$stmt3 = $link->prepare('INSERT INTO messages (room, name, message, time, color) VALUES(:room, :name, :message, :time, :color)');
$stmt3->execute(array(':room' => $Clean['room'],':name' => $Clean['name'],':message' => $Clean['message'],':time' => $time,':color:' => $Clean['color']));
这是我第一次使用PDO(我通常使用mysqli,但我当前的共享主机没有mysqlnd插件,阻止我使用prepare(),所以从这个角度来看任何见解都是值得赞赏的。

问题 - 你会踢自己 - 是:color
。
调用execute()
时为该标记传递的值的数组键名为:color:
。删除尾随:
(我猜这只是一个错字)。
$stmt3->execute(array(
':room' => $Clean['room'],
':name' => $Clean['name'],
':message' => $Clean['message'],
':time' => $time,
':color' => $Clean['color'],
));

我可能在这里错了,但据我所知你需要这样做:
$stmt3->bindParam(':room', $Clean['room']);
$stmt3->bindParam(':name', $Clean['name']);
//and so on
但作为个人偏好,我总是这样做
$stmt3 = $link->prepare('INSERT INTO messages VALUES(null, ?, ?, ?, ?, ?)');
$stmt3->execute(array($Clean['room'], $Clean['name'], $Clean['message'], $time, $Clean['color']))
