本文将指导您如何在Magento中创建新模块和页面，包括模块声明、配置、控制器类、块类、模板定义等步骤，最终实现显示“HelloWorld! I am a Magento Guy…”的页面。

Do you want to create a new page in Magento ? or Do you want to create a new module in Magento ? If yes, Then ok, just spend 10 minutes and follow below steps.

Objectives: I will create a new page in Magento whose output will be “Hello World ! I am a Magento Guy..”.

Target: Create a new module called “HelloWorld”

Step 1 : Module Declaration

Create app/etc/modules/M4U_HelloWorld.xml and write below code

<?xml version="1.0"?>

<config>

         <modules>

                <M4U_HelloWorld>

                        <active>true</active>

                        <codePool>local</codePool>

                </M4U_HelloWorld>

         </modules>

</config>

Step 2: Module Configuration

a. Create a controller class app/code/local/M4U/HelloWorld/controllers/IndexController.php

class M4U_HelloWorld_IndexController extends Mage_Core_Controller_Front_Action

{

    public function indexAction()

    {

     $this->loadLayout(array('default'));

     $this->renderLayout();

    }

}

b. Create a Block class app/code/local/M4U/HelloWorld/Block/HelloWorld.php

class M4U_HelloWorld_Block_HelloWorld extends Mage_Core_Block_Template

{

  // necessary methods

}

c. create configuration xml in app/code/local/M4U/HelloWorld/etc/config.xml

<?xml version="1.0"?>

<config>

	<global>

		<modules>

                <m4u_helloworld>

                        <version>0.1.0</version>

                </m4u_helloworld>

        </modules>

	<blocks>

            <helloworld>

                <rewrite>

		 <helloworld>M4U_HelloWorld_Block_HelloWorld</helloworld>

		</rewrite>

            </helloworld>

	 </blocks>



        </global>

	   <frontend>

                <routers>

                        <helloworld>

                                <use>standard</use>

                                <args>

                                      <module>M4U_HelloWorld</module>

                                      <frontName>helloworld</frontName>

                                </args>

                        </helloworld>

                </routers>

		<layout>

			<updates>

				<helloworld>

		   		      <file>helloworld.xml</file>

				</helloworld>

			</updates>

       		</layout>

        </frontend>

</config>

Define Frontend Template :

1. Define page layout in app/design/frontend/M4U /default/layout/helloworld.xml

N.B: Use default instead of M4U as template location if you use default design packages. Means create file in app/design/frontend/default/default/layout/helloworld.xml

<?xml version="1.0"?>



	<layout version="0.1.0">



		<helloworld_index_index>

			<reference name="root">

				<action method="setTemplate"><template>page/1column.phtml</template></action>

       	 	</reference>

			<reference name="content">

            	<block type="helloworld/helloworld" name="hello" template="helloworld/helloworld.phtml"/>

        	</reference>

		</helloworld_index_index>



	</layout>

2. Create template file app/design/frontend/M4U /default/template/helloworld/helloworld.phtml and write down

N.B: Use default instead of M4U as template location if you use default design packages. Means create file in app/design/frontend/default /default/template/helloworld/helloworld.phtml

Hello World ! I am a Magento Guy..

Hey, new module is ready to run and hit browser with url http://127.0.0.1/projectname/index.php/helloworld/

and see result.

That’s it……..

Is it easy or not ? what you think ?

Coder, Please at first try yourself.

Ohh.., Still are you facing problem ? Lets download full module source code from left panel “BOX” section or let me know.

Note: I have upgraded HelloWorld module source code of BOX widget. So it will resolve the problem which was faced by some guys.
