Using this when not in object context ошибка - Ремонт и установка крупной бытовой техники

You are calling a non-static method :

public function foobarfunc() {
    return $this->foo();
}

Using a static-call :

foobar::foobarfunc();

When using a static-call, the function will be called (even if not declared as static), but, as there is no instance of an object, there is no $this.

So :

You should not use static calls for non-static methods
Your static methods (or statically-called methods) can’t use $this, which normally points to the current instance of the class, as there is no class instance when you’re using static-calls.

Here, the methods of your class are using the current instance of the class, as they need to access the $foo property of the class.

This means your methods need an instance of the class — which means they cannot be static.

This means you shouldn’t use static calls : you should instanciate the class, and use the object to call the methods, like you did in your last portion of code :

$foobar = new foobar();
$foobar->foobarfunc();

For more informations, don’t hesitate to read, in the PHP manual :

The Classes and Objects section
And the Static Keyword page.

Also note that you probably don’t need this line in your __construct method :

global $foo;

Using the global keyword will make the $foo variable, declared outside of all functions and classes, visibile from inside that method… And you probably don’t have such a $foo variable.

To access the $foo class-property, you only need to use $this->foo, like you did.

Are you getting into trouble with the “Using $this when not in object context” error in PHP? Fortunately, you have come to the right place. In this tutorial, we will give you a simple solution to resolve this issue without effort.

Using $this when not in object context: Why is this error coming?

Why did this error happen on your website? This error usually appears once you are writing a static method or calling a method statically. Or you are using $this once it is not in object context.

Initially, you need to understand that $this insides a class denotes the current object. It is what you are generated outside of the class to call class function or variable. Thereby, once you are calling your class function such as
foobar::foobarfunc()
, object is not generated. Whereas inside that function you have written return $this->foo().

As result, here $this is nothing. This is a reason why you get this error.

So, how to handle this problem effectively? In today’s blog, we will provide you with a simple method to help you get rid of this error. Now, let’s check it out.

Using $This When Not In Object Context

How to tackle the error “Using $this when not in object context” in PHP

Now, we will provide you with a quick method to address this issue.

First of all, you need to load your class replace:

foobar::foobarfunc();

By:

(new foobar())->foobarfunc();

Or:

$Foobar = new foobar(); $Foobar->foobarfunc();

Alternatively, you can make a static function to use
foobar::
.

class foobar { //...

static function foobarfunc() { return $this->foo(); } }

Now, you can check if the error is gone.

Привет всем.
Короче вчера обновил битрикс, ядро и модули, теперь при логине на сайте пишет:

[Error] 
Using $this when not in object context (0)
/var/www/u0462316/data/www/reg-inet.ru/bitrix/modules/main/classes/general/user.php:112
#0: CAllUser::GetFullName()
	/var/www/u0462316/data/www/reg-inet.ru/login/index.php:5

Причем заходит нормально…

в файле user.php ругается на 112 строку, там функция

public function GetFullName()
	{
		return $this->GetParam("NAME");
	}

а вызывается функция в индексном файле в папке login:

$userName = CUser::GetFullName();
if (!$userName)
	$userName = CUser::GetLogin();
?>

если правильно понимаю, то переменная $this не может быть использована в контексте стрелочной функции..
Какой выход есть для исправления ошибки?

Using $this when not in object context

Обновление PHP до последних версий повышает безопасность сайта и сокращает время загрузки страниц Joomla 3, поэтому возьмите update php за правило хорошего тона – это будет отличная профилактика программного геморроя. Следуя советам проктолога, я решил обновить PHP на блоге http://stihirus24.ru/ с версии 7.0 до 7.3.1, но печаль сразу же посетила моё сеошное сердце, ибо увидел я красоту со скрина выше.

Поиск корня ошибки

Далее телодвижения были нервные и хаотичные, так как на блоге Zegeberg, где вы и прибываете сейчас, версия 7.3 стала, как родная. Режим отладки при ошибке Joomla Using $this when not in object context показал следующее:

Отчего мозг начал кипеть и выделять ядовитые газы. Советы, консультации, взятки и угрозы позволили выяснить, что гадит на жизнь с высоты птичьего полёта компонент com_xmap, который не испытывает никаких добрых чувств к PHP 7.3. Убирать его не позволила дружбы с детства и верность суровым традициям, поэтому пришлось стать на 5 минут сеошником-хирургом.

замена getMenu()?

Практика хирургии показала, что эпицентр болезни зарыт в 96 строке файла роутер карты сайта:

/components/com_xmap/router.php;

Здесь требуется для полного и долгого счастья просто заменить в 96 строке:

getMenu()?

На:

$menu = JFactory::getApplication()->getMenu();

После этого Joomla 3.9.5 стала работать на PHP 7.3.1 как родная, они слились в единое целое, чем и сделали мне настроение.

Вывод прост – не ищите сложных ответов на простые вопросы, а чаще посещайте блог Zegeberg, слушайте Б.Г., не верьте девушкам со стильными стрижками) и читайте древнегреческих философов.
