register.php

  <?php
//Connection
try {
    $conn = new PDO('mysql:host=localhost;dbname=s', 'root', '*');
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
    echo 'ERROR: ' . $e->getMessage();
}

//Post
$name = $_POST['name'];
$username =$_POST['username'];
$email $_POST['email'];
$password = $_POST['password'];
$password1 = $_POST['passwordconf'];
$ip = $_SERVER['REMOTE_ADDR'];


//Insert into datbase
    $sql = 'INSERT INTO userinfo (name ,username, email, password, ip) VALUES (:name,:username,:email,:password,:ip)';    
    $query = $handler->prepare($sql);

    $query->execute(array(

    ':name' => $name,
    ':username' => $username,
    ':email' => $email,
    ':password' => $password,
    ':ip' => $ip

    ));

?>

连接成功，数据库中存在所有行。我不确定现在去哪里或做什么。任何想法都会很棒。

Answer 1

您似乎使用了错误的变量：

$query = $handler->prepare($sql);

应该是：

$query = $conn->prepare($sql);

这会导致错误......

Answer 2

错误的变量：

$query = $handler->prepare($sql);

<强>校正：

$query = $conn->prepare($sql);

你忘了等号（我建议你用一些IDE来忽略这些愚蠢的错误）：

$email $_POST['email'];

<强>校正：

$email =  $_POST['email'];

Answer 3

试试这个。这些是$email变量中的语法错误，$handler->prepare($sql);应为$conn->prepare($sql);

<?php
//Connection
try {
    $conn = new PDO('mysql:host=localhost;dbname=s', 'root', '*');
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    echo 'ERROR: ' . $e->getMessage();
}

//Post
$name = $_POST['name'];
$username = $_POST['username'];
$email = $_POST['email'];
$password = $_POST['password'];
$password1 = $_POST['passwordconf'];
$ip = $_SERVER['REMOTE_ADDR'];


//Insert into datbase
$sql = 'INSERT INTO userinfo (name ,username, email, password, ip) VALUES (:name,:username,:email,:password,:ip)';
$query = $conn->prepare($sql);

$query->execute(array(
    ':name' => $name,
    ':username' => $username,
    ':email' => $email,
    ':password' => $password,
    ':ip' => $ip
));
?>
