yii 插入语句 SQLSTATE[HY093] 出错：参数号无效：参数未定义

Question

在 Yii 中向表中插入数据时，出现此错误：

CDbCommand failed to execute the SQL statement:
SQLSTATE[HY093]: Invalid parameter number: parameter was not defined.
The SQL statement executed was: insert into user_feedback (name,
desc,email,mobilenumber) values (:Name, :Desc,:email,:Mobilenmber).

下面是我的代码：

$sql = "insert into user_feedback (name, desc,email,mobilenumber) values (:Name, :Desc,:email,:Mobilenmber)";
      $parameters = array(":name"=>$_POST['Name'], ':desc' => $_POST['Desc'],':email'=>$_POST['email'],':mobile_number'=>$_POST['Mobile_nmber']);
      Yii::app()->db->createCommand($sql)->execute($parameters);

Answer 1

您的请求有 2 个错误。 正如亚历山大所说，您的参数不匹配（都期望电子邮件）。 还有打字错误。

这个请求/参数应该工作：

$sql = "insert into user_feedback (name, desc,email,mobilenumber) values (:name, :desc,:email,:mobile_number)";
      $parameters = array(":name"=>$_POST['Name'], ':desc' => $_POST['Desc'],':email'=>$_POST['email'],':mobile_number'=>$_POST['Mobile_number']);

Answer 2

修复参数名称以匹配 select 语句中的参数名称，尝试使用 queryAll 执行此操作，如下所示：

$sql = "insert into user_feedback (name, desc,email,mobilenumber) values (:Name, :Desc,:Email,:Mobilenmber)"; 

$parameters = array(
    ":Name"=>$_POST['Name'],  // names match paremeters in select
    ':Desc' => $_POST['Desc'], // names match paremeters in select
    ':Email'=>$_POST['email'], // names match paremeters in select
    ':Mobilenmber'=>$_POST['Mobile_number']); // names match paremeters 
    // in select plus there is a problem 
    //  with with key (typo) Mobile_number and not Mobile_nmber (unless you defined it this way on purpose !!!)

$command  = Yii::app()->db->createCommand($sql);
$result = $command->queryAll(true,$parameters);

我敢打赌，问题确实出在name列上，它是 MYSQL 关键字name ，请将列名更改为其他名称并尝试一下
