将数据库中的datetime NOW（）用预处理语句插入

Question

我试图在用户进行注册时插入日期但不起作用。当我将NOW()添加到查询时，它没有插入任何内容。如果我删除它，用户将被添加到数据库中。

这是正常的查询

$stmt = $pdo->prepare('INSERT INTO users (username,password,email,active) VALUES (:username, :password, :email, :active'); 
$stmt->execute(array(
    ':username' => $_POST['username'], 
    ':password' => $hashedpassword, 
    ':email' => $_POST['email'], 
    ':active' => $activasion 
)); 

我读过的其他线程并试用了此

$stmt = $pdo->prepare('INSERT INTO users (username,password,email,created,active) VALUES (:username, :password, :email, NOW(), :active'); 
$stmt->execute(array(
    ':username' => $_POST['username'], 
    ':password' => $hashedpassword, 
    ':email' => $_POST['email'], 
    ':active' => $activasion 
)); 

刚刚添加created和NOW()的查询，但没有将任何东西。

可能是什么问题？

Answer 1

你缺少对SQL右括号你正在喂养到prepare()：

$stmt = $pdo->prepare('INSERT INTO users (username,password,email,created,active) VALUES (:username, :password, :email, NOW(), :active'); 

应该

$stmt = $pdo->prepare('INSERT INTO users (username,password,email,created,active) VALUES (:username, :password, :email, NOW(), :active)'); 

由于@VincentDecaux表明，你的错误检查应该抓住这一点。如果您喜欢，请使用以下命令启用例外情况：

$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 

Answer 2

首先尝试抓住你的错误：

try { 
    $stmt = $pdo->prepare('INSERT INTO users (username,password,email,created,active) VALUES (:username, :password, :email, NOW(), :active'); 
    $stmt->execute(array(
     ':username' => $_POST['username'], 
     ':password' => $hashedpassword, 
     ':email' => $_POST['email'], 
     ':active' => $activasion 
    )); 
} 
catch(Exception $e) { 
    echo 'Exception -> '; 
    var_dump($e->getMessage()); 
} 

然后，你可以用这样的方式：

$stmt->execute(array(
    ':username' => $_POST['username'], 
    ':password' => $hashedpassword, 
    ':created' => date('Y-m-d H:i:s'), 
    ':email' => $_POST['email'], 
    ':active' => $activasion 
)); 

Answer 3

尝试的部份

$created = date("Y:m:d h:i:s"); 
$stmt = $pdo->prepare('INSERT INTO users (username,password,email,created,active) VALUES (:username, :password, :email, :created, :active'); 
$stmt->execute(array(
    ':username' => $_POST['username'], 
    ':password' => $hashedpassword, 
    ':email' => $_POST['email'], 
    ':active' => $activasion, 
    ':created' => $created 
));
