问题描述

我遇到一个奇怪的问题，我只是没有找到解决方案.问题在于，准备好的sql语句未绑定值，参数，甚至没有将它们传递给execute函数.而是插入':blah'占位符.如我所说，我尝试了bindParam，bindValue和此方法，但都没有结果.但是，我现在将再次尝试所有这些.

I am having a strange issue that I am just not finding a solution to. The problem is that the prepared sql statement is not binding in values, parameters or even passing them through the execute function. Instead, it inserts the ':blah' placeholder. As I said, I have tried bindParam, bindValue and this method all without result. However, I will try them all again now.

我在执行调用之前输出了要发送的参数.

I outputted the parameters being sent right before the execute call.

Array ( [:username] => schenn [:salt] => NW5552wekj5155cNr52O54q56 [:hashpass] => 5e54240aec6294873d11d6ac3e5b135136a1b671 [:email] => [email protected] [:state] => OR [:country] => USA [:last_login] => 12/08/2011 )

下面是代码:

$query = "INSERT INTO player_acct (username, salt, hashpass, email, state, country, last_login)
                VALUES (':username', ':salt', ':hashpass', ':email', ':state', ':country', ':last_login')";
$stmt = $pdoI->prepare($query);
$params = array(":username" => $this->username, ":salt" => $this->salt, ":hashpass" => $this->hashpass,
                        ":email" => $this->email, ":state" => $this->state, ":country" => $this->country, ":last_login" => $this->last_login );
$stmt->execute($params);

推荐答案

您不应该在SQL中引用占位符.尝试将以下内容作为您的SQL字符串:

You shouldnt be quoting the placeholders in the SQL. Try the following as your SQL string:

$query = "INSERT INTO player_acct (username, salt, hashpass, email, state, country,
          last_login) VALUES (:username, :salt, :hashpass, :email, :state, :country, :last_login)";
