Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]
Type:	bool

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]
Type:	text

zlib in your PHP installation and
special rewrite rules for .css.gzip and .js.gzip

(please see _.htacces for an example). Range 1-9, where 1 is least compression and 9 is greatest compression. true as value will set the compression based on the PHP default settings (usually 5). Suggested and most optimal value is 5.

If set, values of the record are validated after saving in DataHandler. Disable only if using a database in strict mode.

$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’][‘checkStoredRecordsLoose’]¶

checkStoredRecordsLoose¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]
Type:	bool

$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’][‘defaultUserTSconfig’]¶

defaultUserTSconfig¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]
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.

$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’][‘defaultPageTSconfig’]¶

defaultPageTSconfig¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]
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 function ExtensionManagementUtility::addPageTSConfig. It is therefore highly recommended to migrate to using files like EXT:my_sitepackage/Configuration/page.tsconfig instead of setting this global variable.

Read more about Setting the Page TSconfig globally.

$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’][‘defaultPermissions’]¶

defaultPermissions¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]

Type:	array
Default:	[]

Array with sets of custom permission options. Syntax is:

typo3conf/AdditionalConfiguration.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: :|,.

$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’][‘fileDenyPattern’]¶

fileDenyPattern¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]
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 PHP constant FILE_DENY_PATTERN_DEFAULT

interfaces¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]
Type:	text
Default:	backend

This determines which interface options are available in the login prompt

(All options: “backend,frontend”)

$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’][‘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'.

$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’][‘flexformForceCDATA’]¶

flexformForceCDATA¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]
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¶

Path:

$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]

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 the typo3/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.

$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’][‘debug’]¶

debug¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘BE’]

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.

Migration¶

Remove $GLOBALS['TYPO3_CONF_VARS']['BE']['toolbarItems'] from your ext_localconf.php file. If autoconfigure is not enabled in your Configuration/Services.(yaml|php), add the tag backend.toolbar.item to your toolbar item class.
