好吧，最近我看了一个教程，并用 Notepad++ 编写了代码。我正在尝试一个简单的 MYSQL 登录/注册表单，但是当我登录时，它给了我我写的“错误的 U/P”错误回显。它将数据库中的所有内容保存为 md5 等。这是我的代码。
注册.php
<?php
require('config.php');
if(isset($_POST['submit'])){
//Preform the verification of the nation
$email1 = $_POST['email1'];
$email2 = $_POST['email2'];
$pass1 = $_POST['pass1'];
$pass2 = $_POST['pass2'];
if($email1 == $email2) {
if($pass1 == $pass2) {
//All good. Carry on.
$name = mysql_escape_string($_POST['name']);
$lname = mysql_escape_string($_POST['lname']);
$uname = mysql_escape_string($_POST['uname']);
$email1 = mysql_escape_string($_POST['email1']);
$email2 = mysql_escape_string($_POST['email2']);
$pass1 = mysql_escape_string($_POST['pass1']);
$pass2 = mysql_escape_string($_POST['pass2']);
$pass1 = md5($pass1);
$sql = mysql_query("SELECT * FROM `users` WHERE `uname` = '$uname'");
if(mysql_num_rows($sql) > 0) {
echo "Sorry, that user already exists!";
exit();
}
mysql_query("INSERT INTO `users` (`id`, `name`, `lname`, `uname`, `email`, `pass`) VALUES (NULL, '$name', '$lname', '$uname', '$email1', '$pass1')");
}else{
echo "Sorry, your passwords do not match<br><br>";
exit();
}
}else{
echo "Sorry, your emails do not match.<br><br>";
}
}else{
$form = <<<EOT
<form action="register.php" method="POST">
First Name: <input type="text" name="name" /><br />
Last Name: <input type="text" name="lname" /><br />
Username: <input type="text" name="uname" /><br />
Email: <input type="text" name="email1" /><br />
Confirm Email: <input type="text" name="email2" /><br />
Password: <input type="password" name="pass1" /><br />
Confirm Password: <input type="password" name="pass2" /><br />
<input type="submit" value="Register" name="submit" />
</form>
EOT;
echo $form;
}
?>
登录.php
<?php
require('config.php');
if(isset($_POST['submit'])){
$uname = mysql_real_escape_string($_POST['uname']);
$pass = mysql_real_escape_string($_POST['pass']);
$pass = md5($pass);
$sql = mysql_query("SELECET * FROM `users` where `uname` = '$uname' and `pass` = '$pass'");
if(mysql_num_rows($sql) > 0){
echo "You are now logged in.";
exit();
}else{
echo "Wrong U/P combination";
}
}else{
$form = <<<EOT
<form action="login.php" method="POST">
Username: <input tye="text" name="uname" /><br>
Password: <input type="password" name="pass" /><br>
<input type="submit" name="submit" value="Login" />
</form>
EOT;
echo "$form";
}
?>
和 config.php
<?php
mysql_connect("localhost", "X", "X");
mysql_select_db("X");
?>
config.php 代码是正确的，但我不会放弃 X。
如您所见，此代码会在 login.php 不正确时回显错误。即使它是正确的，它也会给我这个错误。我使用了 MD5 哈希通行证，所以请帮忙！
