PDO错误:"参数号无效:参数未定义"

Question

我试图使用一个简单的MySQL插入查询与数组形式的参数.它一直告诉我参数的数量是错误的.我试过以下,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洞察都是值得赞赏的.

问题 - 你会踢自己 - 是:color.

execute()命名时,为调用时传递的值的数组键: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'],
    ));
