Question

我一直在收到SQLSTATE [HY093]错误，但我似乎无法找到它的来源。我试图使用表单的参数将行插入数据库表。

我已经回复了表单中的所有参数，它们都正常工作并正确显示。

$q = "INSERT INTO members (mid, firstname, lastname, username, password, email, phone, street, location, gender, ccnumber, expirymonth, expiryyear) VALUES (NULL, :firstName, :lastName, :username, :password, :email, :phone, :street, :location, :gender, :ccnumber, :expmonth, :expyear);";  
$query = $dbConnect->prepare($q);
    $enc_password = crypt($password,$username);
    //echo 'It is: '.$enc_password.' ';
    //echo 'It is: '.$lastName.' ';
$query->bindParam(":firstname",$firstName);
$query->bindParam(":lastname",$lastName);
    $query->bindParam(":username",$username);
    $query->bindParam(":password",$enc_password);
    $query->bindParam(":email",$email);
$query->bindParam(":phone",$phone);
    $query->bindParam(":street",$street);
    $query->bindParam(":location",$location);
    $query->bindParam(":gender",$gender);
$query->bindParam(":ccnumber",$ccnumber);
    $query->bindParam(":expirymonth",$expmonth);
    $query->bindParam(":expiryyear",$expyear);
    //$query->debugDumpParams();
$result = $query->execute();
return $result;

提前致谢:)！

Answer 1

你有骆驼案：

$q = "INSERT ... :firstName, :lastName ...

然后是小写：

$query->bindParam(":firstname",$firstName);
$query->bindParam(":lastname",$lastName);

看起来像是一个区分大小写的问题。

您的查询中也有：

:expmonth, :expyear

然而你将它们绑定为：

$query->bindParam(":expirymonth",$expmonth);
$query->bindParam(":expiryyear",$expyear);

Answer 2

$查询 - ＆GT; bindParam（＆＃34;：expirymonth＆＃34;，$ expmonth）; $查询 - ＆GT; bindParam（＆＃34;：expiryyear＆＃34;，$ expyear）;

我想，你没有定义＆＃39; expirymonth＆＃39;和＆＃39; expiryyear＆＃39;在您的查询中。相反，你称之为＆＃39;：expmonth，：expyear＆＃39;

SQLSTATE [HY093]：参数号无效：参数未定义...
