BE - backend configuration¶
The following configuration variables can be used to configure settings for the TYPO3 backend:
Note
The configuration values listed here are keys in the global PHP array
$GLOBALS['TYPO3_CONF_VARS']['BE']
.
This variable can be set in one of the following files:
languageDebug¶
Deprecated since version 12.4: Judging from translators feedback, the option is not used in practice: Setting the toggle to true leads to a massively convoluted backend experience that breaks tons of CSS and renders the backend so unusable that it is hardly a benefit at all. The setting will be removed with TYPO3 v13.
- $GLOBALS['TYPO3_CONF_VARS']['BE']['languageDebug']¶
- Type
bool
- Default
false
If enabled, language labels will be shown with additional debug information.
fileadminDir¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['fileadminDir']¶
- Type
text
- Default
'fileadmin/'
Path to the primary directory of files for editors. This is relative to the public web dir. DefaultStorage will be created with that configuration. Do not access manually but via
\TYPO3\CMS\Core\Resource\ResourceFactory::getDefaultStorage().
lockRootPath¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath']¶
- Type
text
- Default
''
This path is used to evaluate if paths outside of the public web path should be allowed. Ending slash required!
userHomePath¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['userHomePath']¶
- Type
text
- Default
''
Combined folder identifier of the directory where TYPO3 backend users have their home-dirs. A combined folder identifier looks like this:
[storageUid]:[folderIdentifier]
. For Example2:users/
. A home for backend user 2 would be:2:users/2/
. Ending slash required!
groupHomePath¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['groupHomePath']¶
- Type
text
- Default
''
Combined folder identifier of the directory where TYPO3 backend groups have their home-dirs. A combined folder identifier looks like this:

. Ending slash required!
userUploadDir¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['userUploadDir']¶
- Type
text
- Default
''
Suffix to the user home dir which is what gets mounted in TYPO3. For example if the user dir is
../123_user/
and this value is/upload
then../123_user/upload
gets mounted.
warning_email_addr¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['warning_email_addr']¶
- Type
text

compressionLevel¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['compressionLevel']¶
- Type
text
- Default
0
- Range
0-9
Determines output compression of BE output. Makes output smaller but slows down the page generation depending on the compression level. Requires
zlib in your PHP installation and
special rewrite rules for
.css.gz
and.js.gz
(before version 12.0 the extension was.css.gzip
and.js.gzip
)
Please see
EXT:install/Resources/Private/FolderStructureTemplateFiles/root-htaccess
for an example. Range1
-9
, where1
is least compression and9
is greatest compression.true
as value will set the compression based on the PHP default settings (usually5
). Suggested and most optimal value is5
.
installToolPassword¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['installToolPassword']¶
- Type
string
- Default
''
The hash of the install tool password.
checkStoredRecords¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['checkStoredRecords']¶

true
If set, values of the record are validated after saving in DataHandler. Disable only if using a database in strict mode.
checkStoredRecordsLoose¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['checkStoredRecordsLoose']¶
- Type
bool
- Default
true
If set, make a loose comparison ( equals 0) when validating record values after saving in DataHandler.
defaultUserTSconfig¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['defaultUserTSconfig']¶
- Type
text
Contains the default user TSconfig.
This variable should not be changed directly but by the following API function. This makes your code less likely to break in the future.
my_sitepackage/ext_localconf.php¶/** * Adding the default User TSconfig */ \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addUserTSConfig(' @import 'EXT:my_sitepackage/Configuration/TsConfig/User/default.tsconfig' ');
Read more about Setting default User TSconfig.
defaultPageTSconfig¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['defaultPageTSconfig']¶
- Type
text
Contains the default page TSconfig.
Never set this configuration variable directly. Use the following methods instead:
New in version 12.0: TSconfig stored in a file
EXT:my_sitepackage/Configuration/page.tsconfig
will be automatically loaded before the content of$TYPO3_CONF_VARS[SYS][defaultPageTSconfig]
.Page TSconfig stored in files like
EXT:my_sitepackage/Configuration/page.tsconfig
are loaded before$TYPO3_CONF_VARS[SYS][defaultPageTSconfig]
. This is done during build-time and therefore more performant than the legacy way of loading default Page Tsconfig during runtime by setting$TYPO3_CONF_VARS[SYS][defaultPageTSconfig]
or the API functionExtensionManagementUtility::addPageTSConfig
. It is therefore highly recommended to migrate to using files likeEXT:my_sitepackage/Configuration/page.tsconfig
instead of setting this global variable.Read more about Setting the Page TSconfig globally.
defaultPermissions¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['defaultPermissions']¶
- Type
array
- Default
[]
This option defines the default page permissions (
show
,edit
,delete
,new
,editcontent
). The following order applies:defaultPermissions
fromTYPO3\CMS\Core\DataHandling\PagePermissionAssembler
$GLOBALS['TYPO3_CONF_VARS']['BE']['defaultPermissions']
(the option described here)Page TSconfig via TCEMAIN.permissions
Example (which reflects the default permissions):
config/system/additional.php | typo3conf/system/additional.php¶$GLOBALS['TYPO3_CONF_VARS']['BE']['defaultPermissions'] = [ 'user' => 'show,edit,delete,new,editcontent', 'group' => 'show,edit,new,editcontent', 'everybody' => '', ];
If you want to deviate from the default permissions, for example by changing the everybody key, you only need to modify the key you wish to change:
config/system/additional.php | typo3conf/system/additional.php¶$GLOBALS['TYPO3_CONF_VARS']['BE']['defaultPermissions'] = [ 'everybody' => 'show', ];
defaultUC¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['defaultUC']¶
- Type
array
- Default
[]
Defines the default user settings. The following order applies:
uc_default
inTYPO3\CMS\Core\Authentication\BackendUserAuthentication
$GLOBALS['TYPO3_CONF_VARS']['BE']['defaultUC']
(the option described here)User TSconfig via setup
Example (which reflects the default user settings):
config/system/additional.php | typo3conf/system/additional.php¶$GLOBALS['TYPO3_CONF_VARS']['BE']['defaultUC'] = [ 'emailMeAtLogin' => 0, 'titleLen' => 50, 'edit_RTE' => '1', 'edit_docModuleUpload' => '1', ];
Visit the setup chapter of the User TSconfig guide for a list of all available options.
customPermOptions¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['customPermOptions']¶
- Type
array
- Default
[]
Array with sets of custom permission options. Syntax is:
config/system/additional.php | typo3conf/system/additional.php¶'key' => array( 'header' => 'header string, language split', 'items' => array( 'key' => array('label, language split','icon reference', 'Description text, language split') ) )
Keys cannot contain characters any of the following characters:
:|,
.
fileDenyPattern¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['fileDenyPattern']¶
- Type
text
- Default
''
A perl-compatible and JavaScript-compatible regular expression (without delimiters
/
) that - if it matches a filename - will deny the file upload/rename or whatever.For security reasons, files with multiple extensions have to be denied on an Apache environment with mod_alias, if the filename contains a valid php handler in an arbitrary position. Also, ".htaccess" files have to be denied. Matching is done case-insensitive.
Default value is stored in class constant
\TYPO3\CMS\Core\Resource\Security\FileNameValidator::FILE_DENY_PATTERN_DEFAULT
.Have also a look into the security guidelines.
interfaces¶
Changed in version 12.0: This option was removed with TYPO3 v12.0.
If a TYPO3 project really relies on this feature, create an
XCLASS of \TYPO3\CMS\Backend\Controller\LoginController
,
where also a custom Fluid template may be used.
explicitADmode¶
Changed in version 12.0: The handling of $GLOBALS['TYPO3_CONF_VARS']['BE']['explicitADmode']
has been changed and
is now set using explicitAllow
. Extensions should not assume this global array
key is set anymore as of TYPO3 Core v12. Extensions that need to stay compatible with v11
and v12 should instead use: $GLOBALS['TYPO3_CONF_VARS']['BE']['explicitADmode'] ?? 'explicitAllow'
.
flexformForceCDATA¶
- flexformForceCDATA']¶
- Type
bool
- Default
0
If set, will add CDATA to Flexform XML. Some versions of libxml have a bug that causes HTML entities to be stripped from any XML content and this setting will avoid the bug by adding CDATA.
versionNumberInFilename¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['versionNumberInFilename']¶
- Type
bool
- Default
false
If enabled, included CSS and JS files loaded in the TYPO3 Backend will have the timestamp embedded in the filename, ie.
filename.1269312081.js
. This will make browsers and proxies reload the files if they change (thus avoiding caching issues).IMPORTANT: This feature requires extra
.htaccess
rules to work (please refer to thetypo3/sysext/install/Resources/Private/FolderStructureTemplateFiles/root-htaccess
file shipped with TYPO3).If disabled the last modification date of the file will be appended as a query-string.
debug¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['debug']¶
- Type
bool
- Default
false
If enabled, the login refresh is disabled and pageRenderer is set to debug mode. Furthermore the fieldname is appended to the label of fields. Use this to debug the backend only!
toolbarItems¶
Warning
This configuration variable has been removed in TYPO3 version 12.0. Setting it has no effect.
Starting with version 12.0 toolbar items implementing
\TYPO3\CMS\Backend\Toolbar\ToolbarItemInterface
are automatically
registered by adding the tag backend.toolbar.item
, if autoconfigure
is enabled in Services.yaml
.
HTTP¶
- $GLOBALS['TYPO3_CONF_VARS']['BE']['HTTP']¶
- Type
array
Set HTTP headers to be sent with each backend request. Other keys than
['Response']['Headers']
are ignored.The default configuration:
[ 'Response' => [ 'Headers' => [ 'clickJackingProtection' => 'X-Frame-Options: SAMEORIGIN', 'strictTransportSecurity' => 'Strict-Transport-Security: max-age=31536000', 'avoidMimeTypeSniffing' => 'X-Content-Type-Options: nosniff', 'referrerPolicy' => 'Referrer-Policy: strict-origin-when-cross-origin', ], ], ]
Changed in version 12.3: The options
strictTransportSecurity
,avoidMimeTypeSniffing
andreferrerPolicy
were added.Note
The
Strict-Transport-Security
is only active, if the option $GLOBALS[TYPO3_CONF_VARS][BE][lockSSL] is enabled.
