【问题描述】：

当我从我的登录或注册脚本重定向到 localhost/ 时收到 403 错误。

这是我的脚本：

    <html>
<center>
<head>
 <title>Login</title>
<font face="Courier" color="green">
<body background=background.png no-repeat center center fixed;
   -webkit-background-size: cover;
   -moz-background-size: cover;
   -o-background-size: cover;
   background-size: cover

<h1>Login</h1>
<?php
if (!isset($_POST['submit'])){
?>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
 Username: <input type="text" name="username" /><br />
 Password: <input type="password" name="password" /><br />

 <input type="submit" name="submit" value="login" />
 </form>
 <?php
 } else{
 require_once("db_const.php");
 $mysqli = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
 #check connection
 if ($mysqli->connect_errno) {
 echo "<p>MySQL error no {$mqsqli->connect_errno} : {$mysql->connect_error}</p>";
 exit();
}

$userame = $_POST['username'];
$password = $_POST['password'];

$sql = "SELECT * from users WHERE username LIKE '{$username}' AND password LIKE '[$password]' LIMIT 1";
$result = $mysqli->query($sql);
if (!$result->num_rows == 1) {
echo "<p>Invalid username/password combination</p>";
} else {
echo "<p>Logged in successfully</p>";

//do stuff
}
}
?>
 </font>
</body>
</center>
</html>

         <br />


  <input type="submit" name="submit" value="register" />
 </form>
 </font>
</center>
<?php
} else {
 $mysqli = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_AGE, DB_Gender);
 if ($mysqli->connect_errno)     {
echo "<p>MySQL error no {$mysqli->connect_errno} : {mysqli->connect_error}</p>";
exit();
}


# prepare data for insertion
$username = $_POST['username'];
$password =$_POST['password'];
$age =$_POST['Age'];
$gender =$_POST['Gender'];

$exists = 0;
$result = $mysqli->query("SELECT username from users WHERE username = '{$username}' LIMIT 1");
if ($result->num_rows == 1) {
$exists = 1;
}

if ($exists == 1)  echo "<p> Username already exists!</p>";
else {
      $sql = "INSERT INTO 'users' ('id', 'username', 'password', 'age', 'gender')
              VALUES (NULL, '{$username}', '{$password}', '{$age}'. '{$gender}')";

    if ($mysqli->query($sql)) {
    //echo "New Record has id" .$mysql->insert_id;
    echo "<p>Registered successfully!</p>";
    } else{
    echo "MySQL error no {mysql->errno} : {$mysql->error}</p>";
    exit();
    }
}
  } 
  ?>
    </body>
    </html>

请见谅，先谢谢了！

另外，有些人可能会评论说我应该对我的密码进行散列或加盐，但这对于这个项目来说不是必需的。

【问题讨论】：

A 403 表示“拒绝访问”，这可能与您的脚本无关。检查您的网络服务器/网络主机设置/

标签： php login registration

【解决方案1】：

你必须在这一行使用echo：

   action="<?php  echo $_SERVER['PHP_SELF']?>"

【讨论】：

刚刚在注册文件上试过了。这是我得到的：Warning: mysqli::mysqli() expects parameter 5 to be long, string given in C:\wamp\www\btyse\register.php on line 46Warning: mysqli::query() [mysqli.query]: Couldn't fetch mysqli in C:\wamp\www\btyse\register.php on line 60Warning: mysqli::query() [mysqli.query]: Couldn't fetch mysqli in C:\wamp\www\btyse\register.php on line 70
这是另一个错误兄弟，这不是关于你的问题，你必须搜索你的新问题，或者只是考虑一下！
