在框架之外的PHP文件中调用OpenCart库函数

在控制器中,我可以轻松调用这样的函数

$this -> user->login('username','password');

但是在单独的PHP 文件框架之外,我该如何访问该方法？我试过这样的东西,但它不起作用：

include($_SERVER['DOCUMENT_ROOT'].'/mydir/opencart/system/library/user.PHP');

$userobj=new User();
$userobj->login('username','password');

你能帮忙吗？

编辑/更新：这是我的startup.PHP 文件中的内容：

<?PHP
// Error Reporting
error_reporting(E_ALL);

// Check Version
if (version_compare(PHPversion(),'5.1.0','<') == true) {
    exit('PHP5.1+ required');
}

// Register Globals
if (ini_get('register_globals')) {
    ini_set('session.use_cookies','On');
    ini_set('session.use_trans_sid','Off');

    session_set_cookie_params(0,'/');
    session_start();

    $globals = array($_REQUEST,$_SESSION,$_SERVER,$_FILES);

    foreach ($globals as $global) {
        foreach(array_keys($global) as $key) {
            unset(${$key}); 
        }
    }
}

// Magic Quotes Fix
if (ini_get('magic_quotes_gpc')) {
    function clean($data) {
        if (is_array($data)) {
            foreach ($data as $key => $value) {
                $data[clean($key)] = clean($value);
            }
        } else {
            $data = stripslashes($data);
        }

        return $data;
    }           

    $_GET = clean($_GET);
    $_POST = clean($_POST);
    $_REQUEST = clean($_REQUEST);
    $_COOKIE = clean($_COOKIE);
}

if (!ini_get('date.timezone')) {
    date_default_timezone_set('UTC');
}

// Windows IIS Compatibility  
if (!isset($_SERVER['DOCUMENT_ROOT'])) { 
    if (isset($_SERVER['SCRIPT_FILENAME'])) {
        $_SERVER['DOCUMENT_ROOT'] = str_replace('\\','/',substr($_SERVER['SCRIPT_FILENAME'],0 - strlen($_SERVER['PHP_SELF'])));
    }
}

if (!isset($_SERVER['DOCUMENT_ROOT'])) {
    if (isset($_SERVER['PATH_TRANSLATED'])) {
        $_SERVER['DOCUMENT_ROOT'] = str_replace('\\',substr(str_replace('\\\\','\\',$_SERVER['PATH_TRANSLATED']),0 - strlen($_SERVER['PHP_SELF'])));
    }
}

if (!isset($_SERVER['REQUEST_URI'])) { 
    $_SERVER['REQUEST_URI'] = substr($_SERVER['PHP_SELF'],1); 

    if (isset($_SERVER['QUERY_STRING'])) { 
        $_SERVER['REQUEST_URI'] .= '?' . $_SERVER['QUERY_STRING']; 
    } 
}

if (!isset($_SERVER['HTTP_HOST'])) {
    $_SERVER['HTTP_HOST'] = getenv('HTTP_HOST');
}

require_once(DIR_SYSTEM . 'library/amazonus.PHP');
?>

而不是这样做：

include($_SERVER['DOCUMENT_ROOT'].'/mydir/opencart/system/library/user.PHP');

(包括仅用户类),包括将从OpenCart加载所有系统类的startup.PHP(可能不需要或可能与您需要使用这些OpenCart类的项目范围发生冲突,但这可以在问题时修复发生).您还需要包含OpenCart的config.PHP,以确保OpenCart的DB类具有连接到已定义的DB所需的常量.您可能希望通过检查文件是否首先存在来以明确的方式执行此操作：

$root = $_SERVER['DOCUMENT_ROOT'] . '/mydir/opencart/';

if (file_exists($root . 'config.PHP')) {
    require_once($root . 'config.PHP');
}
if (file_exists($root . 'system/startup.PHP')) {
    require_once($root . 'system/startup.PHP');
}
if (file_exists($root . 'system/library/user.PHP')) {
    require_once($root . 'system/library/user.PHP');
}

然后您可以尝试登录您的用户：

$user = new User();
if ($user->login('username','password')) {
    echo 'User was logged in successfully';
} else {
    echo 'User not found or username or password do not match.';
}

这将是一个代码示例.

请看一下admin / index.PHP,在创建User对象之前如何实例化所有必需的类.

$registry = new Registry();

$loader = new Loader($registry);
$registry->set('load',$loader);

$config = new Config();
$registry->set('config',$config);

$db = new DB(DB_DRIVER,DB_HOSTNAME,DB_USERNAME,DB_PASSWORD,DB_DATABASE);
$registry->set('db',$db);

// ... do the same for rest of required classes ...

$user = new User($registry);
