Answer 1

I found several errors in your code you can check the below code and let me know if its working

app\code\community\JR\CreateAdminController\controllers\Adminhtml\CustomController.php

<?php
class JR_CreateAdminController_Adminhtml_CustomController extends Mage_Adminhtml_Controller_Action
{
 public function declarationAction()
 {
 $this->loadLayout()
 ->_setActiveMenu('sales')
 ->_title($this->__('Declaration'));
 $this->renderLayout();
 }
}

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>
 <declaration module="jr_createadmincontroller" translate="title">
 <title>Declaration Action</title>
 <sort_order>3</sort_order>
 <action>adminhtml/custom/declaration</action>
 </declaration>
 </children>
 </mycustomtab>
 </menu>
 <acl>
 <resources>
 <admin>
 <children>
 <custom translate="title" module="jr_createadmincontroller">
 <title>My Controller</title>
 <sort_order>-100</sort_order>
 <children>
 <declaration translate="title">
 <title>Declaration Action</title>
 <sort_order>3</sort_order>
 </declaration>
 </children>
 </custom>
 </children>
 </admin>
 </resources>
 </acl>
</config>

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>
 <class>JR_CreateAdminController_Helper</class>
 </jr_createadmincontroller>
 </helpers>
 <blocks>
 <jr_createadmincontroller>
 <class>JR_CreateAdminController_Block</class>
 </jr_createadmincontroller>
 </blocks>
 </global>
 <admin>
 <routers>
 <adminhtml>
 <args>
 <modules>
 <JR_CreateAdminController before="Mage_Adminhtml">JR_CreateAdminController_Adminhtml</JR_CreateAdminController>
 </modules>
 </args>
 </adminhtml>
 </routers>
 </admin>
 <adminhtml>
 <layout>
 <updates>
 <jr_createadmincontroller>
 <file>jr_createadmincontroller.xml</file>
 </jr_createadmincontroller>
 </updates>
 </layout>
 </adminhtml>
</config>

Correct the file name of your xml here

app\design\adminhtml\default\default\layout\jr_createadmincontroller.xml

<?xml version="1.0"?>
<layout>
 <adminhtml_custom_declaration>
 <reference name="content">
 <block type="core/template" name="custom_declaration" template="custom/declaration.phtml" />
 </reference>
 </adminhtml_custom_declaration>
</layout>

Create two additional files

app\code\community\JR\CreateAdminController\Block\Adminhtml\Custom.php

<?php
class JR_CreateAdminController_Block_Adminhtml_Custom extends Mage_Adminhtml_Block_Template
{
}

app\code\community\JR\CreateAdminController\Helper\Data.php

<?php
class JR_CreateAdminController_Helper_Data extends Mage_Core_Helper_Abstract
{
}

Hopes this helps you out !!!

• Ramesh S: No bro still empty imgur.com/siLek3v
• Priyank: Did you correct your xml file name defined in admin layout app\design\adminhtml\default\default\layout\jr_createadmincontroller.xml ? rename this file jr_customcontroller.xml to jr_createadmincontroller.xml
• Ramesh S: Yes bro i did... :(
• Ramesh S: See this imgur.com/a/4d2Be
• Priyank: is your block file being called? Try creating a constructor and print something and test if your blocks get called? Can you update your code in your question to look out what else is missing? This worked for me

Answer 2

Your layout file content should be

<?xml version="1.0"?>
<layout>
 <adminhtml_adminhtml_custom_declaration>
 <reference name="content">
 <block type="jr_createadmincontroller/adminhtml_custom" name="custom_declaration" template="custom/declaration.phtml" />
 </reference>
 </adminhtml_adminhtml_custom_declaration>
</layout>

There is also a custom block needs to be defined along with the above change. It should be like

File : app\code\community\JR\CreateAdminController\Block\Adminhtml\Custom.php

<?php
class JR_CreateAdminController_Block_Adminhtml_Custom extends Mage_Adminhtml_Block_Template
{
}

After these changes are done in your module, then clear your cache and try to load your page again.

• Ramesh S: In template folder am creating a custom/declaration.phtml is this correct ?
• Rajeev K Tomy: it seems correct.
• Ramesh S: But sorry it's not working bro
