To check if user can for example view other users profiles, use this code:
If he doesn't have permission to do it, he will see only error message and script will stop working after trigger_error.
If you want to check a local permission, for example to read posts on forum with ID 5, use this code:
if (!$auth->acl_get('f_read', 5))
Full list of existing permissions is in your database, in phpbb_acl_options table.
Adding a permission
Adding new permissions to Olympus is simple. Example how to add a permission to control who can access foo.php:
- Insert a new row into phpbb_acl_options:
INSERT INTO phpbb_acl_options (auth_option, is_global, is_local, founder_only) VALUES ('u_foo', 1, 0, 0)
- Open language/xx/acp/permissions_phpbb.php and add the language vars:
'acl_u_foo' => array('lang' => 'Can view foo.php', 'cat' => 'misc'),
- Clear the cache folder by hand or use this code in a installer script:
The permission should be ready to assign to users/groups in the acp. To check whether the logged in user has the nescessary permission to view foo.php, use this code in that file:
Hint: You're able to create your own permission set in a separate file. Simply create a new file named permissions_xxx.php in language/xx/mods. It will automaticly included, don't worry about how.
This is a sample file:
* DO NOT CHANGE
if (empty($lang) || !is_array($lang))
$lang = array();
// DEVELOPERS PLEASE NOTE
// All language files should use UTF-8 as their encoding and the files must not contain a BOM.
// Placeholders can now contain order information, e.g. instead of
// 'Page %s of %s' you can (and should) write 'Page %1$s of %2$s', this allows
// translators to re-order the output of data while ensuring it remains correct
// You do not need this where single placeholders are used, e.g. 'Message %d' is fine
// equally where a string contains only two placeholders which are used to wrap text
// in a url you again do not need to specify an order e.g., 'Click %sHERE%s' is fine
// Adding new category
$lang['permission_cat']['mods'] = '.MODS';
// Adding the permissions
$lang = array_merge($lang, array(
'acl_u_foo' => array('lang' => 'Can view foo.php', 'cat' => 'mods'),
