/* ManagePermissions handles all possible permission stuff. The following
functions are used:
void ModifyPermissions()
- calls the right function based on the given subaction.
- checks the permissions, based on the sub-action.
- called by ?action=managepermissions.
- loads the ManagePermissions language file.
void PermissionIndex()
- sets up the permissions by membergroup index page.
- called by ?action=managepermissions
- uses the permission_index template of the ManageBoards template.
- loads the ManagePermissions language and template.
- creates an array of all the groups with the number of members and permissions.
void SetQuickGroups()
- handles permission modification actions from the upper part of the
permission manager index.
// !!!
void SwitchBoard()
- handles the process of switching boards: global to local and vice versa.
- checks the current session and then validates it.
- redirects if the board is already using the permission set being applied to it.
- copies the global permissions over when set to local.
- deletes rows in database for local permissions when switched to global.
void ModifyMembergroup()
- modify (local and global) permissions.
// !!!
void ModifyMembergroup2()
// !!!
void GeneralPermissionSettings()
- a screen to set some general settings for permissions.
void setPermissionLevel(string level, int group, int board = 'null')
- internal function to modify permissions to a pre-defined profile.
// !!!
void loadAllPermissions()
- internal function to load permissions into $context['permissions'].
// !!!
void init_inline_permissions(array permissions)
- internal function to initialise the inline permission settings.
- loads the ManagePermissions language and template.
- loads a context variables for each permission.
- used by several settings screens to set specific permissions.
void theme_inline_permissions(string permission)
- function called by templates to show a list of permissions settings.
- calls the template function template_inline_permissions().
save_inline_permissions(array permissions)
- general function to save the inline permissions sent by a form.
- does no session check.
