# Deprecation: #100053 - GeneralUtility::\_GP()

See [forge#100053](https://forge.typo3.org/issues/100053)

## Description

The method `\TYPO3\CMS\Core\Utility\GeneralUtility::_GP()` has
been marked as deprecated and should not be used any longer.

Modern code should access GET and POST data from the PSR-7 `ServerRequestInterface`,
and should avoid accessing superglobals `$_GET` and `$_POST`
directly. This also avoids future side-effects when using sub-requests. Some
`GeneralUtility` related helper methods like `_GP()` violate this,
using them is considered a technical debt. They are being phased out.

## Impact

Calling the method from PHP code will log a PHP deprecation level entry,
the method will be removed with TYPO3 v13.

## Affected installations

TYPO3 installations with third-party extensions using `GeneralUtility::_GP()`
are affected, typically in TYPO3 installations which
have been migrated to the latest TYPO3 Core versions and
haven't been adapted properly yet.

The extension scanner will find usages with a strong match.

## Migration

`GeneralUtility::_GP()` is a helper method that retrieves
incoming HTTP `GET` query arguments and `POST` body parameters and returns the value.

The same result can be achieved by retrieving arguments from the request object.
An instance of the PSR-7 `ServerRequestInterface` is handed over to
controllers by TYPO3 Core's PSR-15 `\TYPO3\CMS\Core\Http\RequestHandlerInterface`
and middleware implementations, and is available in various related scopes
like the frontend `\TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer`.

Typical code:

```php
use TYPO3\CMS\Core\Utility\GeneralUtility;

// Before
$value = GeneralUtility::_GP('tx_scheduler');

// After
$value = $request->getParsedBody()['tx_scheduler'] ?? $request->getQueryParams()['tx_scheduler'] ?? null;
```
