What is the purpose of an extension key? (3)
The extension key encrypts the extension.
It is the unique identifier for an extension.
The extension directory is named after the extension key.
The extension key guarantees portability and compatibility.
Extension keys can be purchased on typo3.org, so they provide financial backing for the TYPO3 project.
You want to download the data relating to an extension as a SQL dump. What do you need to do? (1)
This is only possible using a tool such as “phpMyAdmin”.
This can be achieved in the Extension Manager using the “Download SQL Dump” function.
You copy the extension directory where all files and data of an extension are saved.
The SQL dump is already contained within the download of an extension using the T3D Export Tool.
This can be achieved in the Install Tool using the “Download SQL Dump” function.
What exactly is deleted when you uninstall an extension in the Extension Manager? (2)
The temporary data of the extension.
The typo3conf/ext/ extension directory.
The extension key in the typo3conf/localconf.php file.
The extension key in the typo3conf/LocalConfiguration.php file.
The corresponding section in the typo3conf/PackageStates.php file.
The corresponding database tables.
A currently installed extension is obviously incompatible with your TYPO3 installation. How can you downgrade to a lower version? (2)
That is not possible. You can only ever install the newest version.
You can install all available versions in the “Get Extensions” sub menu of the Extension Manager.
You can download older versions on typo3.org and uploading them to the TYPO3 instance.
All old versions of an extension are archieved in the typo3temp/extensions/ directory.
You can install these versions by adding _recent to the file name.
How can you ensure, that the Extension Manager installs the latest version of an extension? (2)
You have to update the extension list before installing an extension.
You download the current ZIP file from https://extensions.typo3.org.
You have to tick the “Use latest version” check box in the settings of the Extension Manager.
You have to select “Latest” during the installation of an extension.
In the Install Tool, you have to make sure the option useLatestExtensionVersions is set to true.
When opening the Extension Manager, TYPO3 shows a note that the system is set to composer mode. What does this mean? (3)
The “composer mode” indicates, that TYPO3 runs in a debug mode.
Extensions can be installed/uninstalled using “composer” on the command line.
The Extension Manager can be used to activate or deactivate extensions.
If an extension requires configuration, the XML file of the extension needs to be edited.
With no appropriate access to the command line (e.g. via SSH), extensions can not be added by default.
How can you pass on a version of an extension installed in your system to another developer? (2)
You can download the corresponding ZIP file in the Extension Manager.
You can zip the extension directory and pass it on.
You first have to perform a database dump and then pass it on along with the original extension from the TYPO3 Extension Repository (TER).
There is no straightforward way of doing this, because you have usually made numerous settings in the TYPO3 system which need to be transferred as well.
You can download the extension in the “Extension download” section of the Install Tool.
What does it mean if an extension has the “beta” status? (1)
Such extensions may never be used for production systems.
This status is not really important.
By default, extensions whose status is not “stable” are not displayed in the extension list of the Extension Manager.
Extensions with the “beta” status are automatically deactivated in a productive server.
Extensions with known bugs are automatically marked as in “beta” status.
