I just create a module name referral. Now I want to place the referral block to another module template file name success.phtml. Can it be done?
referral.xml(in referral module)
<?xml version="1.0"?>
<layout version="0.1.0">

</checkout_onepage_success>
<!--block type="referral/referral" name="referralAddSession"><action method="referralAddSession"></action></block-->
</layout>
success.phtml
<?php if($hasBoughtMCash): ?>
<div> Your
<?php echo implode(', ',$hasBoughtMCash); ?>
purchase is successful.
</div>
<?php endif; ?>
<h2>Share in Facebook and Earn for Free MCash!</h2>
<?php echo $this->getChildHtml(); ?>
Referral.php(block)
public function referralCallLink() //success page
{
...
$collection7 = Mage::getModel('referral/referrallink')->getCollection();
$collection7->addFieldToFilter('customer_id', array('eq' => $cust_id));
$collection7->addFieldToFilter('grouped', array('eq' => $grouped));
foreach($collection7 as $data3)
{
$product = $data3->getData('product');
$link = $data3->getData('link');
$imageurl = $data3->getData('url');
//facebook
$title=urlencode('Shop, Save and Get Rewarded at MRuncit.com');
$url=urlencode($link);
$summary=urlencode('I just bought '.$product.' from MRuncit.com and earned some MReward Points!');
$image=urlencode($imageurl);

Answer 1

You should create the block as child of the success block in your layout XML:
<layout_handle_of_the_success_page>
<reference name="name_of_the_success_block_in_layout">
<block type="your/referral_block" />
</reference>
</layout_handle_of_the_success_page>
Then you can insert the following line in success.phtml:
<?php echo $this->getChildHtml('referral'); ?>
There are some names in the example XML that you have to replace with your own:
layout_handle_of_the_success_page - you will find it in the layout XML of the corresponding module. It should be in the form module_controller_action --> checkout_onepage_success
name_of_the_success_block_in_layout - also from the layout XML, look for the block with the success.phtml template and its name attribute --> checkout.success
your/referral_block - that's the class alias of the block that you want to insert in the form module/class --> referral/referral
