Error in getting block in a template

Question

I am a magento beginner and need help with creating a new custom block. Basically, I just want the block to show "hello" if it is called.

1. Module installation xml file, app/etc/modules/MyExtensions_HelloBlock.xml

   <?xml version="1.0" encoding="UTF-8"?>
    <config>
    <modules>
    <MyExtensions_HelloBlock>
    <active>true</active>
    <codePool>local</codePool>
    </MyExtensions_HelloBlock>
    </modules>
   </config>
   

2. Module configuration xml file, app/code/local/MyExtensions/HelloBlock/etc/config.xml

   <?xml version="1.0" encoding="UTF-8"?>
    <config>
    <modules>
    <MyExtensions_HelloBlock>
    <version>0.0.1</version>
    </MyExtensions_HelloBlock>
    </modules>
    <global>
    <blocks>
    <helloblock>
    <class>MyExtensions_HelloBlock_Block</class>
    </helloblock>
    </blocks> 
    </global>
   </config>
   

3. Block class, app/code/local/MyExtensions/HelloBlock/Hello.php.

   <?php
   class MyExtensions_HelloBlock_Block_Hello extends Mage_Core_Block_Template 
   { 
    public function hello()
    {
    echo "hello";
    }
   }
   

4. Template file for the block, app/design/frontend/default/default/template/helloblock/hello.phtml

   <?php
    $this->hello();
   ?>
   

Then I call my new block like this in the template "app/design/frontend/venedor/default/template/page/1column.phtml"

echo $this->getLayout()->createBlock('helloblock/hello')->setTemplate('helloblock/hello.phtml')->toHtml();

Result:

Fatal error: Call to a member function setTemplate() on boolean in /app/design/frontend/venedor/default/template/page/1column.phtml on line 58

I was following this tutorial.

Answer 1

You have added wrong block class, it should be app/code/local/MyExtensions/HelloBlock/Block/Hello.php instead of app/code/local/MyExtensions/HelloBlock/Hello.php

You are missing Block directory in the module

• Black: I still get Fatal error: Call to a member function setTemplate() on boolean
• Piyush: did you moved your block in file inside Block directory?
• Black: "Hello.php" is now at "app/code/local/MyExtensions/HelloBlock/Block/Hello.php"
• Piyush: everything seems right, please check for typo and clear cache once
• Black: Yes you were correct... I accidendially named the folders "MyExtension" instead of "MyExtensions". Thanks!! :)
