在框架外部的PHP文件中调用OpenCart库函数 [英] Calling OpenCart library functions in a PHP file outside of the framework

问题描述

在控制器中，我可以轻松地调用这样的函数

In a controller, I can easily call a function like this

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

但是在框架之外的单独PHP文件中，如何访问该方法?我尝试了类似的方法，但是没有用:

But outside of the framework in a separate PHP file, how can I access that method? I tried something like this but it didn't work:

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

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

可以帮忙吗?

编辑/更新:这是我的startup.php文件中的内容:

Edit/Update: Here is what's inside my startup.php file:

<?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}); 
        }
    }
}

                $data[clean($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')) {

    }
}

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

推荐答案

而不是这样做:

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

(包括user类(仅 ))，包括startup.php，它们将从OpenCart加载所有系统类(可能是不需要的，或者可能与您需要的项目范围冲突)使用这些OpenCart类，但是在出现问题时可以解决此问题.您还需要包括OpenCart的config.php，以确保OpenCart的DB类具有用于连接定义的DB所需的常量.您可能想要通过 clear 方式检查文件是否首先存在:

(including the user class only), include the startup.php that will load all the system classes from OpenCart (may be unwanted or may collide with the scope of project where you need to use those OpenCart classes, but this could be fixed when problems occur). You would need to include the OpenCart's config.php as well to make sure that OpenCart's DB class will have the required constants for connecting to DB defined. You may want to do it in clear way by checking whether the files exist first:

$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，您可以尝试登录用户:

Then you can try to login your user:

$user = new User();
if ($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.

高兴的是，先看看admin/index.php在创建User对象之前如何实例化所有必需的类.

Pleaser, take a look into admin/index.php how all the required classes are instantiated prior to creating the User object.

$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);
