Overview
|
||
|
|
--------
|
||
|
|
|
||
|
|
One of the shared components of the OPNsense framework is the menu system, which
|
||
|
|
is wrapped in a single class and part of the base model.
|
||
|
|
|
||
|
|
The only responsibility of the menu system is to create a tree like structure to
|
||
|
|
represent the menu and being able to keep track of the mapping between a location
|
||
|
|
and the hierarchy of the menu system. To keep things clean and understandable,
|
||
|
|
the menu system doesn't know anything about users or authorisation.
|
||
|
|
|
||
|
|
Currently the main focus for the menu system is to support the legacy code, so
|
||
|
|
we will be able to reimplement the menu in both legacy and new code.
|
||
|
|
|
||
|
|
Our base UI controller (\\OPNsense\\Base\\ControllerBase) implements the menu
|
||
|
|
system for further use.
|
||
|
|
|
||
|
|
An example of how to create a menu, is given below:
|
||
|
|
|
||
|
|
.. code-block:: php
|
||
|
|
|
||
|
|
// create new menu
|
||
|
|
$menu = new Menu\MenuSystem();
|
||
|
|
// append an additional dynamic item into the system
|
||
|
|
$menu->appendItem("System.Advanced", "test123", array("url"=>"/testpage.php","order"=>1));
|
||
|
|
// test, print menu as structured named array
|
||
|
|
print_r($menu->getItems("/testpage.php"));
|
||
|
|
|
||
|
|
The current version only implements a static menu defined by one xml file
|
||
|
|
(models/OPNsense/Base/Menu/Menu.xml), but extending with additional xml files
|
||
|
|
is already supported in the component for future use.
|
||
|
|
|
||
|
|
--------
|
||
|
|
Menu.xml
|
||
|
|
--------
|
||
|
|
|
||
|
|
The menu xml is defined as follows:
|
||
|
|
|
||
|
|
.. code-block:: xml
|
||
|
|
|
||
|
|
<menu>
|
||
|
|
<MainItem order="0" VisibleName="System" cssClass="glyphicon glyphicon-dashboard">
|
||
|
|
<SubItem1 url="/ui/test.php"/>
|
||
|
|
<SubItem2 url="/ui/test2.php"/>
|
||
|
|
</MainItem>
|
||
|
|
</menu>
|
||
|
|
|
||
|
|
The top level should be named "menu" to let the system know this is a menu
|
||
|
|
structure, the next layers will be used for the structure of itself. To map the
|
||
|
|
attributes to the menu objects created there are setters in
|
||
|
|
OPNsense\\Base\\Menu\\MenuItem, in this version the next attributes are supported:
|
||
|
|
|
||
|
|
- order, sort order in our menu
|
||
|
|
- VisibleName, name to use ( if not set the tagname / id will be used)
|
||
|
|
- cssClass, style attributes for the frontend system.
