Useful Information on Using qEngine
Special Variables
There are some special variables in qEngine:
- In UI:
- $login, user login status.
- $current_user_id
- $current_user_level, not used in default qE installation, as there is no user level required in qE. But you can set from 1 to 5, where 5 should have most privilages.
- $outline_tpl_mode, while not really special, usually this variable used to switch mode in outline.tpl by using BEGINIF (read more in BEGINIF document).
- In ACP:
- $current_admin_id
- $current_admin_level, also not really used in default qE. But admin level 5 should be kept by site owner, since this level has the most privalages, including site configuration. For daily administration, please use level 4.
- General:
- $txt (array), contains some information, and used by flush_tpl () function.
- $config (array), contains all configuration settings.
- $lang (array), contains all language variables (see includes/lang.php). A special thing about $lang is that you can use the array keys in lang directly in skin files. Eg, if you set $lang['l_name'], then you can use it directly in any .tpl files by using {$l_name}.
Output Mode
There are several type of output:
- Normal in UI, use: flush_tpl (); at the end of the code.
- Popup in UI, use: flush_tpl ('popup');
- Normal in ACP, use: flush_tpl ('adm');
- Popup in ACP, use: flush_tpl ('adm_popup');
- Printer friendly version, use: flush_tpl ('print');
