尝试使用准备好的语句时出现未捕获的异常 'PDOException'

Question

我是 PDO 的新手，我想了解如何制作准备好的陈述，但我看不出我做错了什么这是我的信息

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY093]: Invalid parameter number: parameter was not defined' in C:\xampp\htdocs\Final\include\addbloguser.php:66 Stack trace: #0 C:\xampp\htdocs\Final\include\addbloguser.php(66): PDOStatement->execute() #1 C:\xampp\htdocs\Final\blogcp.php(49): require('C:\xampp\htdocs...') #2 {main} thrown in C:\xampp\htdocs\Final\include\addbloguser.php on line 66

这是代码。我很确定我犯了很多错误，如果你有时间，你能向我解释我做错了什么以及如何解决吗？

<?php


try {


require SITE_ROOT .  '\include\db_connect.php';

}
catch(PDOException $e)
{ 
echo $e->getMessage();
}


$name = $_POST['fname']; 
$lname = $_POST['lname'];
$username = $_POST['username']; 
$state = "basic"; 
$email = $_POST['email'];   
$password = $_POST['pass']; 
$password1 = $_POST['rpass'];



//verifications

//password 

if (empty($name) || empty($username) || empty($email) || empty($password) || empty($password1)){
    $error = "Complete all fields";
}
if ($password != $password1){
    $error = "Passwords don't match";
}

if (strlen($password) <= 6){
    $error = "Choose a password longer than 6 character";
}


if(!isset($error)){
//no error
$sthandler = $conn->prepare("SELECT username FROM blogusers WHERE username = :username");
$sthandler->bindParam(':username', $username);
$sthandler->execute();

if($sthandler->rowCount() > 0){
    echo "exists! cannot insert";
} else {
    //Securly insert into database
    $sql = 'INSERT INTO blogusers (name , lname ,username, state , email, password) VALUES (:name,:lnane:,:username,:state,:email,:password)';    
    $stmt = $conn->prepare($sql);
    $stmt->bindParam(':name',$name);
    $stmt->bindParam(':lname',$lname);
    $stmt->bindParam(':username',$username);
    $stmt->bindParam(':state',$state);
    $stmt->bindParam(':email',$email);
    $stmt->bindParam(':password',$password);
   $name = $_POST['fname']; 
$lname = $_POST['lname'];
$username = $_POST['username']; 
$state = "basic"; 
$email = $_POST['email'];   
$password = $_POST['pass']; 
    $stmt->execute();
    }
}else{
    echo "error occured: ".$error;
    exit();
}

?>

Answer 1

您的插入正在使用 :lnane:，而您正在绑定 :lname。

$sql = 'INSERT INTO blogusers (name , lname ,username, state , email, password) 
   VALUES (:name,:lnane:,:username,:state,:email,:password)';

更正后的行如下所示：

    $sql = 'INSERT INTO blogusers (name , lname ,username, state , email, password) 
   VALUES (:name,:lname,:username,:state,:email,:password)';
