SessionStorage wrapper

TYPO3 ships a module acting as a wrapper for sessionStorage. It behaves similar to the localStorage, except that the stored data is dropped after the browser session has ended.

The module TYPO3/CMS/Core/Storage/BrowserSession allows to store data in the sessionStorage.

API methods

get(key): Fetches the data behind the key.
set(key, value): Sets/overrides a key with any arbitrary content.
isset(key) (bool): Checks if the key is in use.
unset(key): Removes a key from the storage.
clear(): Empties all data inside the storage.
unsetByPrefix(prefix): Empties all data inside the storage with their keys starting with a prefix.
