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

1 2 3 4 5 6 7 8 9

<?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

1 2 3 4 5 6 7 8

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

1 2 3 4

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

<?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

1 2 3 4 5 6 7 8 9 10 11 12 13 14

<?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
