标签： php html mysqli

我有一个注册表，登录，家庭和用户离线。我正在使用wamp服务器2.5。 login将用户重定向到主页或登录页面。

我的问题是离线一切正常但在线注册表格的工作登录不会重定向到主页。

这是我与mysql代码的连接：

dbconfig.php

<?php

session_start();

$DB_host = "localhost:3306";
$DB_user = "cashgalo";
$DB_pass = "57121363RbK@*<R>";
$DB_name = "cashgalo_bill";

try
{
   $DB_con = new PDO("mysql:host={$DB_host};dbname{$DB_name}",$DB_user,$DB_pass);
 $DB_con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); }
catch(PDOException $e)
{
 echo $e->getMessage();

} 

include_once 'user.php';
$user = new USER($DB_con);

这是我的索引表单，用户在注册后登录

index.php

<?php
require_once 'dbconfig.php';

if($user->is_loggedin()!="")
{
 $user->redirect('homee.php');
 }

 if(isset($_POST['btn-login']))
 {
  $uname = $_POST['txt_uname_email'];
  $umail = $_POST['txt_uname_email'];
  $upass = $_POST['txt_password'];

   if($user->login($uname,$umail,$upass))
   {
    $user->redirect('home.php');
   }
   else
     {
         $error = "Wrong Details !";
      } 
     }
        ?>

        {

         <input type="text" class="form-control" name="txt_uname_email" placeholder="Username or E mail ID" required />
        </div>
        <div class="form-group">
         <input type="password" class="form-control" name="txt_password" placeholder="Your Password" required />
        </div>
        <div class="clearfix"></div><hr />
        <div class="form-group">
         <button type="submit" name="btn-login" class="btn btn-block btn-primary">

    </form>
   </div>
  </div>

这是密码哈希码：

   password hash().php
   <?php

 $password = "123456";
 $hash = password_hash($passwod, PASSWORD_DEFAULT);
 $hashed_password = "$2y$10$BBCpJxgPa8K.iw9ZporxzuW2Lt478RPUV/JFvKRHKzJhIwGhd1tpa";

 /*
 "123456" will become "$2y$10$BBCpJxgPa8K.iw9ZporxzuW2Lt478RPUV/JFvKRHKzJhIwGhd1tpa"
 */ 

?>

这是验证密码：

  password verify().php
  <?php

 $password = "123456";
 $hashed_password = "$2y$10$BBCpJxgPa8K.iw9ZporxzuW2Lt478RPUV/JFvKRHKzJhIwGhd1tpa";
 password_verify($password, $hashed_password);

 /*
  if the password match it will return true.
 */ 

?>

这是用户注册表单

 sign-up.php
 <?php
  require_once 'dbconfig.php';

  if($user->is_loggedin()!="")
  {
  $user->redirect('dashboard.php');
  }

 if(isset($_POST['btn-signup']))
  {
  $uname = trim($_POST['txt_uname']);
  $umail = trim($_POST['txt_umail']);
  $upass = trim($_POST['txt_upass']); 

  if($uname=="") {
     $error[] = "provide username !"; 
     }
    else if($umail=="") {
      $error[] = "provide email id !"; 
    }
     else if(!filter_var($umail, FILTER_VALIDATE_EMAIL)) {
        $error[] = 'Please enter a valid email address !';
    }
     else if($upass=="") {
       $error[] = "provide password !";
     }
   else if(strlen($upass) < 6){
      $error[] = "Password must be atleast 6 characters"; 
   }
   else
    {
  try
  {
     $stmt = $DB_con->prepare("SELECT user_name,user_email FROM users  WHERE user_name=:uname OR user_email=:umail");
     $stmt->execute(array(':uname'=>$uname, ':umail'=>$umail));
     $row=$stmt->fetch(PDO::FETCH_ASSOC);

     if($row['user_name']==$uname) {
        $error[] = "sorry username already taken !";
     }
     else if($row['user_email']==$umail) {
        $error[] = "sorry email id already taken !";
     }
     else
     {
        if($user->register($fname,$lname,$uname,$umail,$upass)) 
        {
            $user->redirect('sign-up.php?joined');
        }
     }
 }
 catch(PDOException $e)
 {
    echo $e->getMessage();
    }
  } 
 }

  ?>

这是我的用户php文件

   user.php
   <?php
    class USER
  {
  private $db;

function __construct($DB_con)
{
  $this->db = $DB_con;

public function register($fname,$lname,$uname,$umail,$upass)

   try
   {
       $new_password = password_hash($upass, PASSWORD_DEFAULT);

       $stmt = $this->db->prepare("INSERT INTO users(user_name,user_email,user_pass) 
                                                   VALUES(:uname, :umail, :upass)");

       $stmt->bindparam(":uname", $uname);
       $stmt->bindparam(":umail", $umail);
       $stmt->bindparam(":upass", $new_password);

   catch(PDOException $e)

         }
         else

   public function is_loggedin()

   }

  public function logout()
  {
    session_destroy();
    unset($_SESSION['user_session']);
    return true;
  }
 }
?>

这是我的用户主页

     <?php
  include_once 'dbconfig.php';
  if(!$user->is_loggedin())
  {
   $user->redirect('index.php');
    }
   $user_id = $_SESSION['user_session'];

 $stmt->execute(array(":user_id"=>$user_id));
 $userRow=$stmt->fetch(PDO::FETCH_ASSOC);
 ?>
