Unable to display "Hello World" from custom module

Question

I am following the book: Getting Started with Magento Extension Development. And I'm unable to make my extension echoing "Hello World".

I believed there are 3 area I need to take care:

1. active the module from app/etc/modules/Froggyline_HappyHour.xml.

2. File: app/code/community/Froggyline/HappyHour/etc/config.xml

   <?xml version="1.0" encoding="UTF-8"?>
   <config>
       <modules>
           <Froggyline_HappyHour>
               <version>0.0.0</version>
           </Froggyline_HappyHour>
       </modules>
       <frontend>
           <routers>
               <froggyline_happyhour>
                   <use>standard</use>
                   <args>
                       <module>Froggyline_Happyhour</module>
                       <frontName>happyhour</frontName>
                   </args>
               </froggyline_happyhour>
           </routers>
       </frontend>
   </config>
   

3. FILE: app/code/community/Froggyline/HappyHour/controller/GreetingController.php

   <?php
   class Froggyline_HappyHour_GreetingController extends Mage_Core_Controller_Front_Action
   {
       public function helloWorldAction()
       {
           echo 'Hello World';
       }
   }
   ?>
   

I am visiting the following URL: http://localhost/happyhour/greeting/helloWorld and receive Http 404.

Which step did I miss, so that the page will display "Hello World"?

Answer 1

this is test and working

app/etc/modules/Froggyline_HappyHour.xml

<?xml version="1.0"?>
<config>
  <modules>
    <Froggyline_HappyHour>
      <active>true</active>
      <codePool>community</codePool>
      <version>0.0.0</version>
    </Froggyline_HappyHour>
  </modules>
</config>

app/code/community/Froggyline/HappyHour/etc/config.xml

<?xml version="1.0"?>
<config>
  <modules>
    <Froggyline_HappyHour>
      <version>0.0.0</version>
    </Froggyline_HappyHour>
  </modules>
  <frontend>
    <routers>
      <happyhour>
        <use>standard</use>
          <args>
            <module>Froggyline_HappyHour</module>
            <frontName>happyhour</frontName>
          </args>
      </happyhour>
    </routers>

  </frontend>

</config> 

missing the controllers folder (s) app/code/community/Froggyline/HappyHour/controllers/GreetingController.php

<?php
class Froggyline_HappyHour_GreetingController extends Mage_Core_Controller_Front_Action{
    public function HelloWorldAction() {

     echo "hello world"; exit;

    }
}

Answer 2

Make sure the version number in the config.xml matches the app/etc/modules/Froggyline_HappyHour.xml

Also, I've never seen a version 0.0.0. Try making it 0.1.0

Answer 3

Glad it worked at last. Don't forget to review all the file names as well...

Everything on the book is alright except in this file:

app/code/community/Foggyline/HappyHour/etc/ config.xml

Where you have to replace

<routers>
  <foggyline_happyhour>
  ...
  <foggyline_happyhour>
<routers>

by

<routers>
  <happyhour>
  ...
  <happyhour>
<routers>
