Question

我试图用PHP OOP创建自己的CMS。基本上我有2个主类文件。其中一个是User.class.php，就像这样：

    <?php 
class User{
    private $db;
    public function __construct()
    {
        $this->db = new Connection();
        $this->db = $this->db->dbConnect();
    }
    public function Login($name, $pass)
    {
        if(!empty($name)&&!empty($pass))
        {
            $st = $this->db->prepare("select * from admins where username=? and password=?");
            $st->bindParam(1,$name);
            $st->bindParam(2,$pass);
            $st->execute();
            if($st->rowCount() == 1)
            {
                header('Location: maint/dashboard.php');
                $_SESSION["admin_username"] = $name;
                $joined = new Joined();
                $joined->Insert($_SESSION["admin_username"]);
                exit();
            }
            else
            {
                header("Location: index.php");
                exit();
            }
        }
    }
}
?>

此类文件实际上是我的登录表单的操作文件。还有另一个名为Joined.class.php的类文件，其中包含：

<?php 
class Joined{
    private $db;
    public function __construct()
    {
        $this->db = new Connection();
        $this->db = $this->db->dbConnect();
    }
    public function Insert($name)
    {
        if(!empty($name))
        {
            $ins = $this->db->prepare("UPDATE admins SET login='NOW()' WHERE username=?");
            $ins->bindParam(1,$name);
            $ins->execute();
        }
    }
}
?>

它的作用是从前一个类文件中获取$_SESSION["admin_username"]并在admins表上运行更新查询，并将我的表上的登录字段设置为当前日期，其中username是等于$_SESSION["admin_username"]。

此代码看起来很完美，并且不会返回任何类型的错误。但是，每当我登录我的帐户时，它也不会更新登录字段，我也不知道为什么！所以，如果您知道如何解决这个问题，请告诉我...提前致谢。

我怀疑某种会话问题。由于您实际上并不需要此部分代码的会话，请在user.class.php中尝试此操作

$joined->Insert($name);

哎呀，我找到了：

    <?php 
class User{
    private $db;
    public function __construct()
    {
        $this->db = new Connection();
        $this->db = $this->db->dbConnect();
    }
    public function Login($name, $pass)
    {
        if(!empty($name)&&!empty($pass))
        {
            $st = $this->db->prepare("select * from admins where username=? and password=?");
            $st->bindParam(1,$name);
            $st->bindParam(2,$pass);
            $st->execute();
            if($st->rowCount() == 1)
            {
                $_SESSION["admin_username"] = $name;
                $joined = new Joined();
                $joined->Insert($_SESSION["admin_username"]);
                header('Location: maint/dashboard.php');
                exit();
            }
            else
            {
                header("Location: index.php");
                exit();
            }
        }
    }
}
?>

基本上，它从上到下读取代码，所以我必须在调用类后调用标题。

$_SESSION["admin_username"] = $name;
            $joined = new Joined();
            $joined->Insert($_SESSION["admin_username"]);
            header('Location: maint/dashboard.php');
            exit();

PHP OOP查询不能正确更新数据库
