Using custom permission options¶
TYPO3 allows extension developers to register their own permission options, managed automatically by the built-in user group access lists. The options can be grouped in categories. A custom permission option is always a checkbox (on/off).
The scope of such options is the backend only.
Options are configured in the global variable
The syntax is demonstrated in the following example, which adds three options under a given header:
$GLOBALS['TYPO3_CONF_VARS']['BE']['customPermOptions'] = array( 'tx_examples_cat1' => array( 'header' => 'LLL:EXT:examples/Resources/Private/Language/locallang.xlf:permissions_header', 'items' => array( 'key1' => array( 'LLL:EXT:examples/Resources/Private/Language/locallang.xlf:permissions_option1', 'EXT:t3skin/icons/gfx/savedok.gif', 'LLL:EXT:examples/Resources/Private/Language/locallang.xlf:permissions_option1_description', ), 'key2' => array('LLL:EXT:examples/Resources/Private/Language/locallang.xlf:permissions_option2'), 'key3' => array('LLL:EXT:examples/Resources/Private/Language/locallang.xlf:permissions_option3'), ) ) );
The result is that these options appear in the group access lists like this:
As you can see it is possible to add both an icon and a description text, that will be displayed as context-sensitive help.
As this is a rather old API the icon is actually pointed to using a reference to an actual file rather than using a sprite class.
To check if a custom permission option is set simply call the API function from the user object:
$BE_USER->check('custom_options', $catKey . ':' . $itemKey);
$catKey is the category in which the option resides. From the example
above this would be
$itemKey is the key of the item in the category you are evaluating.
From the example above this could be
depending on which one of them you want to evaluate.
The function returns true if the option is set, otherwise false.
Keys for options¶
It is good practice to use the extension keys prefixed with
the first level of the array to avoid potential conflicts with other
Never pick a key containing any of the characters “,:\|”. They are reserved delimiter characters.
