Question

我正在允许管理候选人的网站上工作。多种功能已经投入使用，例如高级搜索，带有ajax的候选动态列表，排序，以GDPR格式导出zip格式的候选内容。但是，目前还没有开发任何体系结构。因此，从我的登录表单中，我想添加MVC体系结构。

我是否正确的假设是，模型将包含SQL select语句，控制器将处理数据，例如if（isset（$ _ POST [“ identity”]））{并且视图将包含基本HTML格式用户将在哪里输入数据？

问题在于，从我现有的文件中，我看不到如何添加MVC。

我的config.php最终将变成model.php，index.php，login.php是视图，但是对于控制器，我却陷入困境！：/

配置。 php：

set_5

login.php：

<?php
$host = '127.0.0.1';
$db = 'candidates';
$user = 'root';
$pass = '';
$charset = 'utf8';

$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
$opt = [
    PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION,
    PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
    PDO::ATTR_EMULATE_PREPARES   => false,
    ];

try
{
    $cnx = new PDO($dsn, $user, $pass, $opt);
}
catch(PDOException $e)
{
    die('Connection failed :'. $e->getMessage());
}
?>

实际上，我相信您不只是学习如何将MVC应用于特定问题，而且还可以学习背后的概念和理论。您可以在here中查找基础。

此外，通常建议使用框架，这样您就不会无意间破坏某些设计模式概念。
