Call Any block Or Extension in any Page in Magento

Here I am  using my left navigation extension in home Page.

I  call Extension block in Home page layout . For Home Page we  will edit in local.xml .

Firstly Find Out the block where we used & call it any layout where you want

Like Our Extension block is this :-

<block type="sidenav/navigation" name="codnitive.home.sidenav.content.top" as="codnitiveSidenavContent" before="slider">

                <action method="setTemplate" modules="codnitivecatalog/sidenav/">

                    <template>codnitive/sidenav/navigation.phtml</template>

                </action>

            </block>

Now we put this block in Home Page . So we have to change in  local.xml

Suppose this is  home  page layout here we add left navigation in index reference & before content & before slider so call it just like this in xml File .

Themename/default/layout/local.xml

local.xml

<cms_index_index>

        <reference name="root">

<block type="sidenav/navigation" name="codnitive-home-side-nav" as="codnitive-home-side-nav" before="slider" template="codnitive/sidenav/navigation.phtml">            

            </block>                                              

               

            <!-- define the block slider -->

            <block type="cms/block" name="slider" as="slider" translate="label" before="content" after="codnitive-home-side-nav">

                <action method="setBlockId"><block_id>home-carousel</block_id></action>

            </block>                                                 

                                                                            

        </reference>                                        

        <reference name="left">

            <block type="catalog/navigation" before="-" name="leftNav" as="leftNav" template="catalog/navigation/leftnav.phtml"/>

        </reference>

        <reference name="content">

            <block type="cms/block" name="home-slider-below-banner" before="-" after="slider">

               <action method="setBlockId"><block_id>home-block-below-slider</block_id></action>

           </block>                                               

                                                                                               

        </reference>

    </cms_index_index>

Now this  navigation block call in .phtml file . Here For Home Page Cms we call 1 column layout.

So we call it in theme name/template/page/html.1column.phtml 

Like this

<?php

// call codinative slider

//call block name

echo $this->getChildHtml('codnitive-home-side-nav');

?>
