Custom module does not display in page

Question

I'm trying to add custom block module to homepage but it does not load my block.phtml file. Here are my files: app/etc/modules/MG_Block.xml:

<config>
 <modules>
 <MG_MyBlock>
 <active>true</active>
 <codePool>local</codePool>
 </MG_MyBlock>
 </modules>
</config>

app/code/local/MG/MyBlock/etc/config.xml:

<config>
 <modules>
 <MG_MyBlock>
 <version>0.1.0</version>
 </MG_MyBlock>
 </modules>
 <global>
 <blocks>
 <mg_myblock>
 <class>MG_MyBlock_Block</class>
 </mg_myblock>
 </blocks>
 </global>
</config>`

app/code/local/MG/MyBlock/Block/Products.php:

class MG_MyBlock_Block_Products extends Mage_Core_Block_Abstract{
 public function index(){
 return "hello world";
 }
}

app/design/frontend/rwd/default/template/mg/products.phtml:

<?php echo $this->index(); ?>

app/design/frontend/rwd/default/layout/local.xml:

<layout version="0.1.0">
 <default>
 <reference name="content"> 
 <block type="mg_myblock/products" output="toHtml" name="myblock" template="mg/products.phtml" after="-" />
 </reference>
 </default>
</layout>

When I use var_dump in _construct() function in my block it shows var_dump but it does not load template file.

• Suresh Chikani: add your controller code for more idea.
• marcin.g: I extend Mage_Core_Block_Template instead of Mage_Core_Block_Abstract and it works.

Answer 1

First add "module.xml" in layout tag in "config.xml".

<config>
 <modules>
 <MG_MyBlock>
 <version>0.1.0</version>
 </MG_MyBlock>
 </modules>
 <global>
 <blocks>
 <mg_myblock>
 <class>MG_MyBlock_Block</class>
 </mg_myblock>
 </blocks>
 </global>
 <frontend>
 <routers>
 <myblock>
 <use>standard</use>
 <args>
 <module>myblock</module>
 <frontName>formtest</frontName>
 </args>
 </myblock>
 </routers>
 <layout>
 <updates>
 <mymodule>
 <file>mymodule.xml</file>
 </mymodule>
 </updates>
 </layout>
 </frontend>
</config>

Then define "module.xml".

<layout version="0.1.0">
 <formtest_myblock_index>
 <reference name="content"> 
 <block type="mg_myblock/products" output="toHtml" name="myblock" template="mg/products.phtml" after="-" />
 </reference>
 </formtest_myblock_index>
</layout>

Try with this.

Rename the file MG_Block.xml in app/etc/modules/ to MG_MyBlock.xml
