custom phtml not loading from custom layout magento

Question

My custom controller is loaded.

I want my phtml file to called from the layout.

I have tried as below:

\app\etc\modules\Mymodule_Customerpage.xml

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

\app\code\community\Mymodule\Customerpage\etc\config.xml

<?xml version="1.0" encoding="UTF-8"?>
 <config>
<modules>
    <Mymodule_Customerpage>
        <version>1.0.0</version>
    </Mymodule_Customerpage>
</modules>
<frontend>
    <layout>
        <updates>
            <mymodule_customerpage module="Mymodule_Customerpage">
                <file>mymodule_customerpage.xml</file>
            </mymodule_customerpage>
        </updates>
    </layout>    
    <routers>
        <mymodule_customerpage>
            <use>standard</use>
            <args>
                <module>Mymodule_Customerpage</module>
                <frontName>mymodule_customerpage</frontName>
            </args>
        </mymodule_customerpage>
    </routers>        
</frontend>

<global>
    <helpers>
        <mymodule_customerpage>
            <class>Mymodule_Customerpage_Helper</class>
        </mymodule_customerpage>
    </helpers>        
</global>

</config>

\app\design\frontend\base\default\template\mymodule_customerpage.phtml

<layout>
<customer_account>
    <reference name="customer_account_navigation">
        <action method="addLink">
            <name>my_module_section</name>
            <path>mymodule_customerpage/index/index</path>
            <label>My Module Link</label>
        </action>
    </reference>
</customer_account>

<mymodule_customerpage_index_index>
    <update handle="customer_account" />
    <reference name="my.account.wrapper">
        <block type="core/template" name="mymodule_customerpage_content" template="mymodule_customerpage.phtml"/>            
    </reference>
</mymodule_customerpage_index_index>

<!--  <mymodule_customerpage_recipecreation_index>

<!-- <default>
    <reference name="rec_creation_page">

</default> -->

</layout>

app\design\frontend\base\default\template\mymodule_customerpage.phtml

<?php
<div class="dashboard">
    <?php echo $this->getMessagesBlock()->getGroupedHtml() ?>
    <div class="box-account box-info">
        <div class="box-head">
            <h2><?php echo $this->__('Manage My Recipes') ?></h2>
        </div>
    </div>
</div>

<div class="page-title">
    <form action="<?php echo $this->getUrl('mymodule_customerpage/recipeCreation/index') ?>" method="post" id="form-validate" autocomplete="off">
        <button type="submit" class="button" title="<?php echo $this->__('Add New Recipe') ?>">
            <span><span><?php echo $this->__('Add New Recipe') ?></span></span>
        </button>
    </form>
</div>

app\code\community\Mymodule\Customerpage\controllers\RecipeCreationController.php

class Mymodule_Customerpage_RecipeCreationController extends Mage_Core_Controller_Front_Action {
public function preDispatch()
{
    parent::preDispatch();
    $action = $this->getRequest()->getActionName();
    $loginUrl = Mage::helper('customer')->getLoginUrl();

    if (!Mage::getSingleton('customer/session')->authenticate($this, $loginUrl)) {
        $this->setFlag('', self::FLAG_NO_DISPATCH, true);
    }
}      
public function indexAction()
{
    echo 'rec cre controller';
    $this->loadLayout();
    $this->renderLayout();
}
}

here when i click on Add new recipe button...

My controller mymodule_customerpage/recipeCreation/index/ is loading with blank page, which should call my phtml

Have placed phtml both in these locations and tried:

\app\design\frontend\default\default\template\addrecipe\createrecipe.phtml

\app\design\frontend\base\default\template\addrecipe\createrecipe.phtml

<?php
<div>
    <?php echo 'Create'; ?>
</div>

Answer 1

You have just little bit Case Sensitive mistake in you code

mymodule_customerpage_recipeCreation_index

To

mymodule_customerpage_recipecreation_index

Replace below code to in your layout file mymodule_customerpage.xml

<layout>
<mymodule_customerpage_recipecreation_index>
    <reference name="content">
        <block type="core/template" name="rec_creation" template="createrecipe.phtml"/>            
    </reference>
</mymodule_customerpage_recipecreation_index> 
</layout>

Answer 2

Try this,

Instead of this <reference name="rec_creation_page"> you try this <reference name="content">

<block type="customerpage/customerpage" name="rec_creation" template="createrecipe.phtml"/> change this also

<block type="customerpage/customerpage" name="rec_creation" template="foldername/createrecipe.phtml"/>
