config.xml not loading properly

Question

I have created a custom module probably 20 times and it is showing the same 404 error.

I have searched for an issue and eventually found nothing. isn't it because I am using ubuntu.

Please correct me if I am wrong.

This is my app/etc/Kuldeep_HelloWorld.xml file:

<?xml version="1.0"?>
<config>
    <modules>
        <Kuldeep_HelloWorld>
            <active>true</active>
            <codePool>local</codePool>
        </Kuldeep_HelloWorld>
    </modules>
</config>

This is app/code/local/Kuldeep/HelloWorld/etc/config.xml

<?xml version="1.0"?>
<config>
  <modules>
    <Kuldeep_HelloWorld>
      <version>0.1.0</version>
    </Kuldeep_HelloWorld>
  </modules>
  <frontend>
    <routers>
      <helloworld>
        <use>standard</use>
        <args>
          <module/>Kuldeep_HelloWorld</module>
          <frontName>hey</frontName>
        </args>
      </helloworld>
    </routers>
  </frontend>
<admin>
  <routers>
    <helloworld>
     <use>admin</use>
     <args>
      <module>Kuldeep_HelloWorld</module>
      <frontName>admin_helloworld</frontName>
     </args>
    </helloworld>
  </routers>
</admin>
<global>
  <helpers>
    <helloworld>
      <class>Kuldeep_HelloWorld_Helper</class>
    </helloworld>
  </helpers>
</global>
<adminhtml>
 <menu>
   <helloworld module="helloworld">
     <title>HelloWorld</title>
     <sort_order>100</sort_order>
    <children>
      <helloworld module="helloworld">
        <title>Hello World</title>
        <sort_order>0</sort_order>
        <action>admin_helloworld/adminhtml_index</action>
      </helloworld>
    </children>
   </helloworld>
 </menu>
</adminhtml>
</config>

This is controller file: app/code/local/Kuldeep/HelloWorld/controllers/IndexController.php

<?php
class Kuldeep_HelloWorld_IndexController extends Mage_Core_Controller_Front_Action{

   /**
   * Index action
   *
   * @access public

   * @return void
   */
   public function indexAction() {

      echo "it works!";

   }

   public function doneintagainAction() {

      echo "done it again....!!!!";
      }
}
?>

Answer 1

You have a syntax error in your etc/config.xml:

<module/>Kuldeep_HelloWorld</module>

If you notice in the first module tag, you have a slash. Change it to this:

<module>Kuldeep_HelloWorld</module>

Also, you never noted which URLs you are trying. Could you post those?

app/code/local/Kuldeep/Helloworld/controllers/IndexController.php

<?php
class Kuldeep_Helloworld_IndexController extends Mage_Core_Controller_Front_Action
{

   public function indexAction()
   {
       echo "it works!";
   }

   public function doneintagainAction()
   {
       echo "done it again....!!!!";
   }
}

/*you dont need to close a php tag-> "?>" */

NB: you need an adminhtml controller for your menu, the first one that you created was for frontend.

app/code/local/Kuldeep/Helloworld/controllers/Adminhtml/MenuController.php

<?php

class Kuldeep_Helloworld_Adminhtml_MenuController extends Mage_Adminhtml_Controller_Action
{
    public function indexAction()
    {
        $this->loadLayout()
            ->_setActiveMenu('menu/menu')
            ->_title($this->__('Submenu1'));
        $this->renderLayout();
    }
}
