Script Extensions
LIMBAS allows inclusion of extensions for special applications. There are two options:
Extend LIMBAS core with your own script
When LIMBAS is started, it identifies all files “ext_*.inc” from the directory ./dependent/EXTENSIONS and any subdirectories. Prior to the execution of a script .php, .dao or .lib it is verified if one or more (from various subdirectories) ext_.inc are present. If so they will be executed if necessary.
In the current version the following Source Files can be extended:
| Source Script | Extension Name | Execution | Functionality in LIMBAS |
| main.php | ext_main.inc | Skriptmitte | Home Page |
| main.php | ext_main.js | Skriptende | Home Page Javascript Body elements |
| main_admin.php | ext_main_admin.inc | Script middle | Admin Home Page |
| main_dyns.php | ext_ajax.inc | Skript start | Home Page for Ajax-Calls |
| gtab/gtab.lib | ext_gtab.inc | Skriptanfang | Basic functions for all database queries and changes |
| gtab/html/gtab_erg.php | ext_gtab_erg.inc | Script start | Functions for the list view |
| gtab/html/gtab_erg.dao | ext_gtab_erg_dao.inc | Script start | Functions for the list view |
| gtab/dao/gtab_change.dao | ext_gtab_change.inc | Script start | Functions for the detail view |
| lib/session_auth.lib | ext_session_auth.inc | Script end | Functions for the Session Initialization |
| lib/session_auth.lib | ext_ldap.inc | Script start | Functions for LDAP authentication |
| extra/report/report.dao | ext_report.inc | Skriptanfang | Funktionen für Reports |
| extra/explorer/filestructure.lib | ext_explorer.inc | Script start | Functions for LIMBAS DMS |
| layout/nav.php | ext_nav.inc | Script end | Extension of the navigation bar |
| extra/multiframe/multiframe.dao | ext_multiframe.inc | Script end | Functions for displays in the multi-purpose window on the right edge of the browser |
| layout/style/css.php | ext_css.inc | Script end | Extension for overrides of the main stylesheet of Limbas (for direct layout adjustments) |
| main.php | ext_main.css | Script middle | Additionally integrated CSS for own extensions |
Generally, unlimited extension scripts can be created, using the same name but saved in different folders. You can create your own folder structure in the ./dependent/EXTENSIONS directory which will give you a better overview.
Expand LIMBAS with own functions
The script to be executed by LIMBAS, must be in the directory ./dependent/EXTENSIONS or a subdirectory in a file with the extension *.ext
In Admin->Setup->Menu Items the script has to be selected, for the menu item that triggers the execution of the script. If the menu item already has a Limbas action the originally planned action will not be executed. Additionally own menu items can be added. These can be authorized and used to the full extend in extensions. Actions or links that are not used in menus can also be used like “menu items”.
Note:
Please bear in mind, that the select field is only available when the menue item has a unique action name.
In the example the file helloworld.ext is executed. It includes the following example code:
Example:
<?php
echo "hello world";
?>The action can now be call by the following link: http://…openlimbas/dependent/main.php?action=nav_meinMenue.
Extend the main.php with the file ext_main.inc
This file must be created in the directory /dependent/EXTENSIONS or a subdirectory. In order to select an extension for a new main menue item first an action must be inserted.
The action can be any name which will later be used to call the extension. (attention: each name can only be used once)
The call is carried out by the additon of the limbas link by “main.php?action=NAME_OF_THE_ACTION”.
Example: ext_main.inc:
<?
if($action == 'nav_myMenue' ){
#require('a file you need');
echo "hallo";
$action='null';
}
?>The line “$action=’null'” is an important entry, because otherwise all following actions will be executed.
If you call now the link …/main.php?action=nav_myMenue in the browser you can see the return value “hello”.
