<?xml version="1.0"?>

    <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.
