如果配置类,我首先有三个文件,第二个是用户类,第三个是索引文件。
的config.php
class connection{
public function dbConnect()
{
new PDO("mysql:host=localhost:3306;dbname=education","root","");
}
}
user.php的
<?php
session_start();
require_once '../cms/config.php';
class user{
private $db;
public function __construct()
{
$this->db= new connection();
$this->db= $this->db->dbConnect();
return $this->db;
}
public function login($user,$pass)
{
//creating a array for future usage
if(!empty($user) && !empty($pass))
{
$st=$this->db->prepare("select * from admin where admin_user=? AND admin_pass=?");
$st->bindParam(1,$user);
$st->bindParam(2,$pass);
$st->execute();
if($st->rowCount()==1)
{
$_SESSION['admin_user']=$user;
header("Location:admin.php");
}
else
{
$_SESSION['errorMessage']="Incorrect username or password!Please try again.";
echo $_SESSION['errorMessage'];
}
}
else
{
echo "Hey! Don't leave me empty";
}
}
}
?>
的index.php
require_once '../cms/user.php';
if(isset($_POST['submit']))
{
$user=$_POST['user'];
$user= mysql_real_escape_string($user);
$pass=$_POST['pass'];
$pass= mysql_real_escape_string($pass);
$object=new user();
$object->login($user,$pass);
}
当我尝试使用错误或正确的数据登录时,会抛出fatel错误。即使是昨天的工作文件。但今天发生了什么。这很烦人。 请帮忙。

您需要返回pdo实例。
class connection{
public function dbConnect()
{
// here, you need to return it
return new PDO("mysql:host=localhost:3306;dbname=education","root","");
}
}
