PHP登录表单不能正常工作

-2

我正在创建一个登录表单，但是一旦提交表单就没有做任何事情.. PHP不起作用.. 没有用。这是我的代码：PHP登录表单不能正常工作

的login.php：显示

<? 
    $con = mysqli_connect("localhost", "root", "pass", "DB"); 
    //Login Script 
    if (isset($_POST["email"]) && isset($_POST["password_login"])) { 
     $user_login = ($_POST["email"]); // filter everything but numbers and letters 
     $password_login = preg_replace('#[^A-Za-z0-9]#i', '', $_POST["password_login"]); // filter everything but numbers and letters 
     $md5password_login = md5($password_login); 
     $sql = mysqli_query($con, "SELECT id FROM users WHERE email='$user_login' AND password='$md5password_login' AND closed='no' LIMIT 1"); // query the person 
     //Check for their existance 
     $userCount = mysql_num_rows($sql); //Count the number of rows returned 
     if ($userCount == 1) { 
      while($row = mysql_fetch_array($sql)){ 
       $id = $row["id"]; 
     } 
      $_SESSION["id"] = $id; 
      $_SESSION["user_login"] = $user_login; 
      $_SESSION["password_login"] = $password_login; 
      exit("<meta http-equiv=\"refresh\" content=\"0\">"); 
      } else { 
      echo 'That information is incorrect, try again'; 
      exit(); 
     } 
    } 
    ?>

删除＃尽管如此，没有变化... –

<?php ...... your code ?>

–

变化按钮，输入型提交和代码其他许多错误的检查，仔细像J-查询ü没有给“＃”同时拍下按钮的编号 –

你在混合库文件。 mysqli不是 = mysql。你想要的是这样的：

$userCount = mysqli_num_rows($sql);

同样的事情也适用于$row = mysql_fetch_array($sql)，那将需要是：

$row = mysqli_fetch_array($sql)

此外，您的会话将不会被设定，因为你还没有开始它！如果你想使用会话，你需要开始他们每页，你打算使用它们：

<?php 
session_start();

请永远不要使用此代码投入生产。它很容易受到SQL Injection的影响，您应该至少对变量进行清理，但使用PDO或Mysqli Prepared Statements来代替。

注：看来你对（<? ?>）PHP短标记所以这不是问题，但不是每个主持人都会有其打开，所以最好使用正确的标签：

从行动=“＃”
