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.

Target: Create a new module called “HelloWorld”
Step 1: Module Declaration
Create app/etc/modules/Tatva_HelloWorld.xml and write below code

1   <?xml version="1.0"?>   
2   <config>   
3            <modules>   
4                   <Tatva_HelloWorld>   
5                           <active>true</active>   
6                           <codePool>local</codePool>
7                   </Tatva_HelloWorld>   
8            </modules>   
9   </config>   
 

Step 2: Module Configuration

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

1   class Tatva_HelloWorld_IndexController extends Mage_Core_Controller_Front_Action
2   {   
3       public function indexAction()   
4       {   
5        $this->loadLayout(array('default'));   
6        $this->renderLayout();   
7       }   
8   }   
 

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

1   class Tatva_HelloWorld_Block_HelloWorld extends Mage_Core_Block_Template
2   {   
3     // necessary methods   
4   }   
 

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

01   <?xml version="1.0"?>   
02   <config>   
03       <global>   
04           <modules>   
05                   <tatva_helloworld>   
06                           <version>0.1.0</version>   
07                   </tatva_helloworld>   
08           </modules>   
09       <blocks>   
10               <helloworld>   
11                   <rewrite>   
12            <helloworld>Tatva_HelloWorld_Block_HelloWorld</helloworld>
13           </rewrite>   
14               </helloworld>   
15        </blocks>   
16       
17           </global>   
18          <frontend>   
19                   <routers>   
20                           <helloworld>   
21                                   <use>standard</use>   
22                                   <args>   
23                                         <module>Tatva_HelloWorld</module>
24                                         <frontName>helloworld</frontName>
25                                   </args>   
26                           </helloworld>   
27                   </routers>   
28           <layout>   
29               <updates>   
30                   <helloworld>   
31                         <file>helloworld.xml</file>   
32                   </helloworld>   
33               </updates>   
34               </layout>   
35           </frontend>   
36   </config>   
 

Define Frontend Template :

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

01   <?xml version="1.0"?>   
02       
03       <layout version="0.1.0">   
04       
05           <helloworld_index_index>   
06               <reference name="root">   
07                   <action method="setTemplate"><template>page/1column.phtml</template></action>
08               </reference>   
09               <reference name="content">   
10                   <block type="helloworld/helloworld" name="hello" template="helloworld/helloworld.phtml"/>
11               </reference>   
12           </helloworld_index_index>   
13       
14       </layout>   
 

2. Create template file app/design/frontend/Tatva/default/template/helloworld/helloworld.phtml and write down
N.B: Use default instead of Tatva as template location if you use default design packages. Means create file in app/design/frontend/default/default/template/helloworld/helloworld.phtml
