問題描述

我已經(jīng)嘗試了很多方法來使用下面的代碼(來自較大班級的片段)獲取最后插入的 ID，現(xiàn)在我已經(jīng)放棄了.

I have tried lots of ways to get the last inserted ID with the code below (snipplet from larger class) and now I have given up.

有誰知道如何讓 PDO lastInsertId 工作?

Does anyone know howto get PDO lastInsertId to work?

提前致謝.

    $sql = "INSERT INTO auth (surname, forename, email, mobile, mobilepin, actlink, regdate) VALUES (:surname, :forename, :email, :mobile, :mobpin, :actlink, NOW())";
$stmt = $this->dbh->prepare($sql);
if(!$stmt) {
 return "st";
}

$stmt->bindParam(':surname', $this->surname);
$stmt->bindParam(':forename', $this->forename);
$stmt->bindParam(':email', $this->email);
$stmt->bindParam(':mobile', $this->mobile);
$stmt->bindParam(':mobpin', $this->mobilePin);
$stmt->bindParam(':actlink', $this->actlink);

$result = $stmt->execute();
//return var_dump($result);
$arr = array();
$arr = $stmt->errorInfo();
$_SESSION['record'] = 'OK' . $dbh->lastInsertId();
$arr .= $_SESSION['record'];
return $arr;

推薦答案

在您的代碼片段中，我看到了一些可能對問題產(chǎn)生影響的輕微不一致.例如，在準(zhǔn)備您使用的 SQL 語句的代碼中，

In your code snippet, I saw some minor inconsistencies that may have an effect on the problem. For an example, in the code to prepare your SQL statement you use,

$stmt = $this->dbh->prepare($sql); 

注意 $this 關(guān)鍵字.然后要檢索 ID，您調(diào)用，

Notice the $this keyword. Then to retrieve the ID, you call,

$dbh->lastInsertId();

你有沒有試過使用，

$this->dbh->lastInsertId();

這篇關(guān)于PDO lastInsertId 問題，php的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
