The script tried to execute a method or access a property of an incomplete object
提问by Irfan
I'm getting an error, the full error is:
我收到一个错误，完整的错误是：
Fatal error: authnet_cart_process() [<a href='function.authnet-cart-process'>function.authnet-cart-process</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "AuthnetCart" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /home/golfetc/public_html/wp-content/plugins/sccp-2.4.0/authnet_functions.php on line 1266
I'm using session to store cart object in it and get it later at some point. The authnetCart is basically class for cart object.
我正在使用会话将购物车对象存储在其中，并在稍后获取它。authnetCart 基本上是购物车对象的类。
// Check cart in session
if(isset($_SESSION['AUTHNET_CART'])) {
// Get cart from session
$authnetCart = $_SESSION['AUTHNET_CART'];
foreach($authnetCart->getCartItems() as $item) { // Line#1266
if ($item->getItemId() == $subscription_details->ID ) {
$addNewItem = false;
break;
}
}
......
You can see at line 1266, the code doesn't allow me to access its method. Any help will be highly appreciated. Thanks
您可以在第 1266 行看到，该代码不允许我访问其方法。任何帮助将不胜感激。谢谢

You need to include/ requirethe php with your class BEFOREsession_start()like
你需要include/require你的类PHP之前session_start()一样
include PATH_TO_CLASS . 'AuthnetClassFilename.php';
session_start();
if (isset($_SESSION['AUTHNET_CART'])) {
//...
}

It seems like your answer is in the error message.
您的答案似乎在错误消息中。
Before unserializing AUTHNET_CART, include the class which defines it. Either manually, or using an autoloader.
在反序列化 AUTHNET_CART 之前，包括定义它的类。手动或使用自动加载器。
include PATH_TO_CLASS . 'AuthnetClassFilename.php';
if(isset($_SESSION['AUTHNET_CART'])) {//...
It doesn't appear that you're actually unserializing it either (I'm assuming this was serialized before stuffing it into the session?)
看起来您实际上也没有对其进行反序列化（我假设在将其放入会话之前已对其进行了序列化？）
if(isset($_SESSION['AUTHNET_CART'])) {
// Get cart from session
/** UNSERIALIZE **/
$authnetCart = unserialize($_SESSION['AUTHNET_CART']);
foreach($authnetCart->getCartItems() as $item) { // Line#1266
if ($item->getItemId() == $subscription_details->ID ) {
$addNewItem = false;
break;
}
}
...

None of the other answers in here actually solved this problem for me.
这里的其他答案都没有真正为我解决这个问题。
In this particular case I was using CodeIgniter and adding any of the following lines before the line that caused the error:
在这种特殊情况下，我使用 CodeIgniter 并在导致错误的行之前添加以下任何行：
$this->load->model('Authnet_Class');
OR
或者
get_instance()->load->model('Authnet_Class')
OR
或者
include APPPATH . '/model/Authnet_Class.php';
Did notsolve the problem.
难道没有解决的问题。
I managed to solve it by invoking the class definition in the constructof the class where I was accessing Authnet_Class. I.e.:
我设法通过在我访问的类的构造中调用类定义来解决它Authnet_Class。IE：
class MY_Current_Context_Class extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('Authnet_Class');
}
// somewhere below in another function I access Authnet_Class ...
I now understand that the context where you access the Authnet_Classclass, needs to have its definition present on the context's class construct (and not just before you invoke the properties of Authnet_Class).
我现在明白，您访问Authnet_Class类的上下文需要在上下文的类构造中存在其定义（而不仅仅是在调用 的属性之前Authnet_Class）。
