的login.php

Question

我正在创建一个配置文件页面和一个登录页面，其中我存储会话ID，然后在配置文件中我检查是否isset但我得到的问题是系统总是显示错误消息，我使用< strong> print_r（$ _ SESSION）; 浏览器显示：

重要数据缺失（[first_name] =＆gt; [email] =＆gt;）

如何解决此错误?????

的login.php

<?php
session_start();
error_reporting(E_ALL);
require_once('include/connect.php');
$message = ""; 
if(!empty($_POST['email']))
{

$email = $_POST['email'];
$pass = $_POST['pass'];

$email = strip_tags($email);
$pass = strip_tags($pass);
$email = mysql_real_escape_string($email);
$pass = mysql_real_escape_string($pass);
//$pass = md5($pass);

$sql=mysql_query( "SELECT user_id, email_address, first_name FROM user WHERE email_address='$email'AND password='$pass'LIMIT 1") or die("error in user table");
$login_check = mysql_num_rows($sql);

  if($login_check > 0)
  {
      $row = mysql_fetch_array($sql);

          $id = $row['user_id'];
          $_SESSION['user_id'] = $id;

          $firstname = $row['first_name'];
          $_SESSION['first_name']= $firstname;

          $email = $row['email_address'];
          $_SESSION['email_address']= $email;

          mysql_query("UPDATE user SET last_log_date=now() WHERE user_id='$id'");

          header("Location: profile.php");    
  }//close if 
  else
  {
      $message = "incorrect Email or Password!!";
      //exit();
  }
}//close if

Answer 1

你需要改变一些事情

首先：在您的请求中获取first_name和电子邮件

'SELECT user_id,email,first_name FROM user WHERE email_address='$email'AND password='$pass'LIMIT 1'

其次，删除while循环并执行

$row = mysql_fetch_array($sql);

您限制为1个结果，因此无需在结果中循环

将$id=$_SESSION['user_id'];更改为$_SESSION['user_id'] = $id;

此外，将配置文件和删除循环的结果限制为1（user_id =＆gt; UNIQUE =＆gt; LIMIT 1）

Answer 2

所有你需要做的就是在一切结账后在会话变量[$ _SESSION ['username']]中存储一个值，然后使用会话中的值从mysql表中选择数据

----------------------------------例如----------- -------------------------------------------

登录login.php

if($login_check > 0)
{
  $_SESSION['email']=$email;//storing variable in SESSION
 header("Location: profile.php");    
}
else
{
  $message = "incorrect Email or Password!!";
  die();// kill the script
}

在profile.php上

<?php
session_start();// start session
require_once('include/connect.php'); //include connection file

$sql = mysql_query("SELECT * FROM user  WHERE email='(mysql_real_escape_string($_SESSION['email']))'") or die(mysql_error());
$row = mysql_fetch_array($sql);
// then just echo all the data you need
?>

个人资料页面无法使用会话ID

的login.php

profile.php
