in my backend I have admin and managers. Managers have short functional. But I want show some content ALL backend users, not only admins. I use $this->tsfe->beUserLogin construction, and this content visible only for admins.
UPD I have FE module, it placed into several page. In my extension I have .php and .tpl files. I transmit $variable=$GLOBALS['TSFE']->beUserLogin from .php to .tpl file, and in .tpl I have construction if(variable) <div>...</div>. In the page I don't have div, if I don't have admin account.
if($GLOBALS['TSFE']->beUserLogin) die('Logged BE user'); if I am admin, it's work, but for another users script continue work.The managers have access only to folder with content element, but don't have to page, where this content placed.
The common backend user (not admin) need to have the access to the page at least possibility to see it on the Page tree (in WEB>Access module at least first option (ShowPage) must be marked for the group of the user)
Otherwise the $GLOBALS['TSFE']->beUserLogin var considers there's no logged BE user (or there's no BE user allowed to see this page as an admin).
