我正在尝试为客户端编写注册页面，但此错误每时每刻都出现。
Failed to run query: SQLSTATE[HY093]: Invalid parameter number: parameter was not defined
我遵循了这个教程:http://untame.net/2013/06/how-to-build-a-functional-login-form-with-php-twitter-bootstrap/DB是:DB
代码如下:
<?php
require("config.php");
if(empty($_SESSION['user']))
{
header("Location: index.php");
die("Redirecting to index.php");
}
require("config.php");
if(!empty($_POST))
{
// Ensure that the user fills out fields
if(empty($_POST['username']))
{ die("Please enter a username."); }
if(empty($_POST['password']))
{ die("Please enter a password."); }
if(!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL))
{ die("Invalid E-Mail Address"); }
// Check if the username is already taken
$query = "
SELECT
1
FROM users
WHERE
username = :username
";
$query_params = array( ':username' => $_POST['username'] );
$query_params = array( ':nombre' => $_POST['nombre'] );
$query_params = array( ':empresa' => $_POST['empresa'] );
$query_params = array( ':apellidos' => $_POST['apellidos'] );
try {
$stmt = $db->prepare($query);
$result = $stmt->execute($query_params);
}
catch(PDOException $ex){ die("Failed to run query: " . $ex->getMessage()); }
$row = $stmt->fetch();
if($row){ die("This username is already in use"); }
$query = "
SELECT
1
FROM users
WHERE
email = :email
";
$query_params = array(
':email' => $_POST['email']
);
try {
$stmt = $db->prepare($query);
$result = $stmt->execute($query_params);
}
catch(PDOException $ex){ die("Failed to run query: " . $ex->getMessage());}
$row = $stmt->fetch();
if($row){ die("This email address is already registered"); }
// Add row to database
$query = "
INSERT INTO users (
username,
password,
salt,
email,
empresa,
nombre,
apellidos
) VALUES (
:username,
:password,
:salt,
:email,
:empresa,
:nombre,
:apellidos
)";
/*

// Security measures
$salt = dechex(mt_rand(0, 2147483647)) . dechex(mt_rand(0, 2147483647));
$password = hash('sha256', $_POST['password'] . $salt);
for($round = 0; $round < 65536; $round++){ $password = hash('sha256', $password . $salt); }
$query_params = array(

':password' => $password,
':salt' => $salt,

);
try {
$stmt = $db->prepare($query);
$result = $stmt->execute($query_params);
}
catch(PDOException $ex){ die("Failed to run query: " . $ex->getMessage()); }
header("Location: index.php");
die("Redirecting to index.php");
}

我看到所有的变量都是好的，我不知道错误在哪里。
我config。
<?php
// These variables define the connection information for your MySQL database
$username = "root";
$password = "root";
$host = "localhost";
$dbname = "4tickets";
$options = array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8');
try { $db = new PDO("mysql:host={$host};dbname={$dbname};charset=utf8", $username, $password, $options); }
catch(PDOException $ex){ die("Failed to connect to the database: " . $ex->getMessage());}
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
header('Content-Type: text/html; charset=utf-8');
session_start();
?>
我只添加了3个东西:empresa, nombre和apellidos，这些都不是教程中需要的。
提前感谢，约翰。
你在这里传递错误的参数:
// Check if the username is already taken
$query = "
SELECT
1
FROM users
WHERE
username = :username
";
$query_params = array( ':username' => $_POST['username'] );
$query_params = array( ':nombre' => $_POST['nombre'] );
$query_params = array( ':empresa' => $_POST['empresa'] );
$query_params = array( ':apellidos' => $_POST['apellidos'] );
你试图传递太多的参数，但是你每次都覆盖了$query_params。取出本节中的hombre, empress和apellidos，它应该提交。
