Hello everyone! I’ve recently got frustrated with Magento’s core functionality which requires XML definition for Administration menus. And I really wanted to add quick website / store links to it. Solution was to overwrite one of Magento’s Adminhtml blocks, and inject my non-XML, dynamic menu to it. If you’re interested in how I did it, read on.

To make it upgradeable, and painless, I’ve decided to make an extension just for this. It consists of only 2 Files, config.xml, and one Block rewrite.

First, I’ve created config.xml, and set it like this:

<?xml version="1.0" encoding="UTF-8"?>
<config><modules><Inchoo_ExtendedMenu><version>0.1.0</version></Inchoo_ExtendedMenu></modules><global><blocks><configurable><class>Inchoo_Configurable_Block</class></configurable><adminhtml><rewrite><page_menu>Inchoo_ExtendedMenu_Block_Adminhtml_Menu</page_menu></rewrite></adminhtml></blocks></global>
</config>

And since Magento parses XML as always, ideal solution for me was to hook on that parsed data just before printing the menu. So, block I mentioned earlier is “Mage_Adminhtml_Block_Page_Menu”. And here, I was interested in getMenuArray() method, and since it looks like this:

/*** Retrieve Adminhtml Menu array** @return array*/
public function getMenuArray()
{return $this->_buildMenuArray();
}

This was the bes place to interfere in Magento’s core. I’ve created my own class “Inchoo_ExtendedMenu_Block_Adminhtml_Menu” with source code:

<?php
class Inchoo_ExtendedMenu_Block_Adminhtml_Menu extends Mage_Adminhtml_Block_Page_Menu
{public function getMenuArray(){//Load standard menu$parentArr = parent::getMenuArray();//Prepare "View Sites" menu$parentArr['view_sites'] = array('label' => 'View Sites','active'=>false ,'sort_order'=>0,'click' => 'return false;','url'=>'#','level'=>0,'last'=> true,'children' => array());$app = Mage::app();$j = 0;$allWebsites = $app->getWebsites();$totalWebsiteCount = count($allWebsites) - 1;foreach ($allWebsites as $_eachWebsiteId => $websiteVal){$_storeName = $app->getWebsite($_eachWebsiteId)->getName();$_websiteUrl = array('label' => $_storeName,'active' => false ,'url' => '#','click' => "return false",'sort_order' => $j++ * 10,'level' => 1,'children' => array());if(count($parentArr['view_sites']['children']) == $totalWebsiteCount){$_websiteUrl['last'] = true;} else {$_websiteUrl['last'] = false;}$parentArr['view_sites']['children'][$j - 1] = $_websiteUrl;$allStores = $app->getWebsite($app->getWebsite($_eachWebsiteId)->getId())->getStores();$totalCount = count($allStores);$i = 0;foreach ($allStores as $_eachStoreId => $val){$_websiteId = $app->getStore($_eachStoreId)->getWebsiteId();if($_websiteId == $j){$_storeName = $app->getStore($_eachStoreId)->getName();$baseUrl = $app->getStore($_eachStoreId)->getUrl();$_websiteUrl = array('label' => $_storeName,'active' => false ,'click' => "window.open(this.href, 'Website - ' + this.href); return false;",'sort_order' => $i++ * 10,'level' => 2,'url' => $baseUrl);if(count($parentArr['view_sites']['children'][$j - 1]['children']) + 1 == $totalCount or $totalCount == 0)$_websiteUrl['last'] = true;else$_websiteUrl['last'] = false;$parentArr['view_sites']['children'][$j - 1]['children'][$i] = $_websiteUrl;}}}return $parentArr;}
}

What I did her was overwrite of “getMenuArray()” call on parent method, and population of resulting array with my own dynamic menu.

Result looks like this on default Magento 1.5.0.1 installation:

And you can download it here.

As always, please make backup before installation, as this is provided for usage at your own risk.

We have already seen in a previous post how to override a controller into Magento. This time I’ll show you how to create your own controller in admin panel in an efficiant way, because there are many solutions here and there but they do not always work and are sometimes obsolete. We will access our controller under a new custom tab.

Overview

Before showing you the code, here is what the admin panel will look like:

And here is the module structure:

Module configuration

app/code/community/JR/CreateAdminController/etc/config.xml:

<?xml version="1.0"?>
<config><modules><JR_CreateAdminController><version>1.0.0</version></JR_CreateAdminController></modules><global><helpers><jr_createadmincontroller><!-- Helper definition needed by Magento --><class>Mage_Core_Helper</class></jr_createadmincontroller></helpers></global><admin><routers><adminhtml><args><modules><foo_bar before="Mage_Adminhtml">JR_CreateAdminController_Adminhtml</foo_bar></modules></args></adminhtml></routers></admin>
</config>

Tabs and sub-tabs creation

app/code/community/JR/CreateAdminController/etc/adminhtml.xml:

<?xml version="1.0" encoding="UTF-8"?>
<config><menu><mycustomtab module="jr_createadmincontroller" translate="title"><title>My Custom Tab</title><sort_order>100</sort_order><children><index module="jr_createadmincontroller" translate="title"><title>Index Action</title><sort_order>1</sort_order><action>adminhtml/custom</action></index><list module="jr_createadmincontroller" translate="title"><title>List Action</title><sort_order>2</sort_order><action>adminhtml/custom/list</action></list></children></mycustomtab></menu><acl><resources><admin><children><custom translate="title" module="jr_createadmincontroller"><title>My Controller</title><sort_order>-100</sort_order><children><index translate="title"><title>Index Action</title><sort_order>1</sort_order></index><list translate="title"><title>List Action</title><sort_order>2</sort_order></list></children></custom></children></admin></resources></acl>
</config>

Controller creation

app/code/community/JR/CreateAdminController/controllers/Adminhtml/CustomController.php:

<?phpclass JR_CreateAdminController_Adminhtml_CustomController extends Mage_Adminhtml_Controller_Action
{public function indexAction(){$this->loadLayout()->_setActiveMenu('mycustomtab')->_title($this->__('Index Action'));// add template
$this->_addContent($this->getLayout()->createBlock('adminhtml/template')->setTemplate('lookbook/list.phtml'));$this->renderLayout();}public function listAction(){$this->loadLayout()->_setActiveMenu('mycustomtab')->_title($this->__('List Action'));// my stuff$this->renderLayout();}
}
